Android app development is currently the 4 most sought-after digital skill on Indeed, which means there are plenty of opportunity for freelance Android app developers. The fastest way to learn Android development is online.
Android apps are written using the Java programming language. The combination of these three tools will give you the full integrated development environment you require to start building Android apps.
Take an Android development course online. The best way to learn is by diving in and hacking together some basic apps. I also recommend reviewing their new introduction to creating apps with Material Design.
Google has created an Android Developer portal where you can get everything you need to start creating your first Android app. These are the most up-to-date resources that I have found for learning Android app development online.
Updated for the latest version of Android 5 Lollipop. This course has assignments and video lectures that will help you build your first mobile apps for either Android or the iPhone or iPad.
You can only go so far with free resources. The best way to learn a difficult technical skill like Android app development is to join an online coding bootcamp. Internal hardware, such as accelerometers, gyroscopes and proximity sensors are used by some applications to respond to additional user actions, for example adjusting the screen from portrait to landscape depending on how the device is oriented, [67] or allowing the user to steer a vehicle in a racing game by rotating the device, simulating control of a steering wheel.
Android devices boot to the homescreen, the primary navigation and information "hub" on Android devices, analogous to the desktop found on personal computers. Android homescreens are typically made up of app icons and widgets ; app icons launch the associated app, whereas widgets display live, auto-updating content, such as a weather forecast, the user's email inbox, or a news ticker directly on the homescreen.
Along the top of the screen is a status bar, showing information about the device and its connectivity. This status bar can be "pulled" down to reveal a notification screen where apps display important information or updates.
An All Apps screen lists all installed applications, with the ability for users to drag an app from the list onto the home screen. A Recents screen lets users switch between recently used apps.
Applications " apps " , which extend the functionality of devices, are written using the Android software development kit SDK [76] and, often, the Java programming language. The SDK includes a comprehensive set of development tools, [83] including a debugger, software libraries, a handset emulator based on QEMU, documentation, sample code, and tutorials.
Android has a growing selection of third-party applications, which can be acquired by users by downloading and installing the application's APK Android application package file, or by downloading them using an application store program that allows users to install, update, and remove applications from their devices.
Google Play Store is the primary application store installed on Android devices that comply with Google's compatibility requirements and license the Google Mobile Services software.
Due to the open nature of Android, a number of third-party application marketplaces also exist for Android, either to provide a substitute for devices that are not allowed to ship with Google Play Store, provide applications that cannot be offered on Google Play Store due to policy violations, or for other reasons.
F-Droid, another alternative marketplace, seeks to only provide applications that are distributed under free and open source licenses. Since Android devices are usually battery-powered, Android is designed to manage processes to keep power consumption at a minimum.
When an application is not in use the system suspends its operation so that, while available for immediate use rather than closed, it does not use battery power or CPU resources.
The software is available for developers, and was released in Since, Android devices with Intel processors began to appear, including phones [] and tablets. While gaining support for bit platforms, Android was first made to run on bit x86 and then on ARM Android devices incorporate many optional hardware components, including still or video cameras, GPS, orientation sensors, dedicated gaming controls, accelerometers, gyroscopes, barometers, magnetometers, proximity sensors, pressure sensors, thermometers, and touchscreens.
Some hardware components are not required, but became standard in certain classes of devices, such as smartphones, and additional requirements apply if they are present. Some other hardware was initially required, but those requirements have been relaxed or eliminated altogether.
For example, as Android was developed initially as a phone OS, hardware such as microphones were required, while over time the phone function became optional. In addition to running on smartphones and tablets, several vendors run Android natively on regular PC hardware with a keyboard and mouse.
Android is developed by Google until the latest changes and updates are ready to be released, at which point the source code is made available to the Android Open Source Project. In, the green Android logo was designed for Google by graphic designer Irina Blok.
The design team was tasked with a project to create a universally identifiable icon with the specific inclusion of a robot in the final design. After numerous design developments based on science fiction and space movies, the team eventually sought inspiration from the human symbol on restroom doors and modified the figure into a robot shape.
As Android is open-source, it was agreed that the logo should be likewise, and since its launch the green logo has been reinterpreted into countless variations on the original design.
Google announces major incremental upgrades to Android on a yearly basis. Compared to its primary rival mobile operating system, Apple 's iOS, Android updates typically reach various devices with significant delays.
Except for devices within the Google Nexus brand, updates often arrive months after the release of the new version, or not at all. The lack of after-sale support from manufacturers and carriers has been widely criticized by consumer groups and the technology media.
In, Google began decoupling certain aspects of the operating system particularly its core applications so they could be updated through the Google Play store independently of the OS.
One of those components, Google Play Services, is a closed-source system-level process providing APIs for Google services, installed automatically on nearly all devices running Android 2.
With these changes, Google can add new system functionality through Play Services and update apps without having to distribute an upgrade to the operating system itself. In May, Bloomberg reported that Google was making efforts to keep Android more up-to-date, including accelerated rates of security updates, rolling out technological workarounds, reducing requirements for phone testing, and ranking phone makers in an attempt to "shame" them into better behavior.
As stated by Bloomberg: Wireless carriers were described in the report as the "most challenging discussions", due to carriers' slow approval time due to testing on their networks, despite some carriers, including Verizon and Sprint, having already shortened their respective approval times.
HTC 's then-executive Jason Mackenzie called monthly security updates "unrealistic" in, and Google was trying to persuade carriers to exclude security patches from the full testing procedures.
In a further effort for persuasion, Google shared a list of top phone makers measured by updated devices with its Android partners, and is considering making the list public.
Mike Chan, co-founder of phone maker Nextbit and former Android developer, said that "The best way to solve this problem is a massive re-architecture of the operating system", "or Google could invest in training manufacturers and carriers "to be good Android citizens"".
Android's kernel is based on one of the Linux kernel 's long-term support LTS branches. As of, Android devices mainly use versions 3. Android's variant of the Linux kernel has further architectural changes that are implemented by Google outside the typical Linux kernel development cycle, such as the inclusion of components like device trees, ashmem, ION, and different Out of memory OOM handling.
In August, Linus Torvalds said that "eventually Android and Linux would come back to a common kernel, but it will probably not be for four to five years". The interfaces are the same but the upstream Linux implementation allows for two different suspend modes: However, root access can be obtained by exploiting security flaws in Android, which is used frequently by the open-source community to enhance the capabilities of their devices, [] but also by malicious parties to install viruses and malware.
Android is a Linux distribution according to the Linux Foundation, [] Google's open-source chief Chris DiBona, [] and several journalists. As of latest version, Android Oreo, Google "mandates a minimum kernel version and kernel configuration" for security reasons, e.
On top of the Linux kernel, there are the middleware, libraries and APIs written in C, and application software running on an application framework which includes Java - compatible libraries.
Development of the Linux kernel continues independently of other Android's source code bases. Following the trace-based JIT principle, in addition to interpreting the majority of application code, Dalvik performs the compilation and native execution of select frequently executed code segments "traces" each time an application is launched.
For its Java library, the Android platform uses a subset of the now discontinued Apache Harmony project. Bionic itself has been designed with several major features specific to the Linux kernel.
At the same time, Bionic is licensed under the terms of the BSD licence, which Google finds more suitable for the Android's overall licensing model. Android does not have a native X Window System by default, nor does it support the full set of standard GNU libraries.
Since Marshmallow, " Toybox ", a collection of command line utilities mostly for use by apps, as Android doesn't provide a command line interface by default, replaced similar "Toolbox" collection.
Android has an active community of developers and enthusiasts who use the Android Open Source Project AOSP source code to develop and distribute their own modified versions of the operating system.
Historically, device manufacturers and mobile carriers have typically been unsupportive of third-party firmware development. Manufacturers express concern about improper functioning of devices running unofficial software and the support costs resulting from this.
As a result, technical obstacles including locked bootloaders and restricted access to root permissions are common in many devices. However, as community-developed software has grown more popular, and following a statement by the Librarian of Congress in the United States that permits the " jailbreaking " of mobile devices, [] manufacturers and carriers have softened their position regarding third party development, with some, including HTC, [] Motorola, [] Samsung [] [] and Sony, [] providing support and encouraging development.
As a result of this, over time the need to circumvent hardware restrictions to install unofficial firmware has lessened as an increasing number of devices are shipped with unlocked or unlockable bootloaders, similar to Nexus series of phones, although usually requiring that users waive their devices' warranties to do so.
They are reportedly able to read almost all smartphone information, including SMS, location, emails, and notes. GCHQ has, according to The Guardian, a wiki - style guide of different apps and advertising networks, and the different data that can be siphoned from each.
The documents revealed a further effort by the intelligence agencies to intercept Google Maps searches and queries submitted from Android and other smartphones to collect location information in bulk.
Research from security company Trend Micro lists premium service abuse as the most common type of Android malware, where text messages are sent from infected phones to premium-rate telephone numbers without the consent or even knowledge of the user.
Other malware displays unwanted and intrusive advertisements on the device, or sends personal information to unauthorised third parties. In August, Google announced that devices in the Google Nexus series would begin to receive monthly security patches.
Google also wrote that "Nexus devices will continue to receive major updates for at least two years and security patches for the longer of three years from initial availability or 18 months from last sale of the device via the Google Store.
Google was starting from scratch with zero percent market share, so it was happy to give up control and give everyone a seat at the table in exchange for adoption.
As such, security has become a big issue. Android still uses a software update chain-of-command designed back when the Android ecosystem had zero devices to update, and it just doesn't work".
And a bunch of broken promises". They also wrote that "About half of devices in use at the end of had not received a platform security update in the previous year", stating that their work would continue to focus on streamlining the security updates program for easier deployment by manufacturers.
Patches to bugs found in the core operating system often do not reach users of older and lower-priced devices. For example, Samsung has worked with General Dynamics through their Open Kernel Labs acquisition to rebuild Jelly Bean on top of their hardened microvisor for the "Knox" project.
Android smartphones have the ability to report the location of Wi-Fi access points, encountered as phone users move around, to build databases containing the physical locations of hundreds of millions of such access points.
These databases form electronic maps to locate smartphones, allowing them to run apps like Foursquare, Google Latitude, Facebook Places, and to deliver location-based ads. Android applications run in a sandbox, an isolated area of the system that does not have access to the rest of the system's resources, unless access permissions are explicitly granted by the user when the application is installed.
Since February, Google has used its Google Bouncer malware scanner to watch over and scan apps available in the Google Play store. Before installing an application, the Google Play store displays a list of the requirements an app needs to function.
After reviewing these permissions, the user can choose to accept or refuse them, installing the application only if they accept. An opt-in system is used instead, in which users are prompted to grant or deny individual permissions to an app when they are needed for the first time.
Applications remember the grants, which can be revoked by the user at any time. Permissions can still be revoked for those apps, though this might prevent them from working properly, and a warning is displayed to that effect.
Nova wrote that "The Android operating system deals with software packages by sandboxing them; this does not allow applications to list the directory contents of other apps to keep the system safe.
By not allowing the antivirus to list the directories of other apps after installation, applications that show no inherent suspicious behavior when downloaded are cleared as safe.
The study by Fraunhofer AISEC, examining antivirus software from Avast, AVG, Bitdefender, ESET, F-Secure, Kaspersky, Lookout, McAfee formerly Intel Security, Norton, Sophos, and Trend Micro, revealed that "the tested antivirus apps do not provide protection against customized malware or targeted attacks", and that "the tested antivirus apps were also not able to detect malware which is completely unknown to date but does not make any efforts to hide its malignity".
In August, Google announced Android Device Manager renamed Find My Device in May, [] [] a service that allows users to remotely track, locate, and wipe their Android device, [] [] with an Android app for the service released in December.
The source code for Android is open-source: Google publishes most of the code including network and telephony stacks under the non-copyleft Apache License version 2. Associated Linux kernel changes are released under the copyleft GNU General Public License version 2, developed by the Open Handset Alliance, with the source code publicly available at all times.
Typically, Google collaborates with a hardware manufacturer to produce a flagship device part of the Nexus series featuring the new version of Android, then makes the source code available after that device has been released.
The reason, according to Andy Rubin in an official Android blog post, was because Honeycomb was rushed for production of the Motorola Xoom, [] and they did not want third parties creating a "really bad user experience" by attempting to put onto smartphones a version of Android intended for tablets.
These applications must be licensed from Google by device makers, and can only be shipped on devices which meet its compatibility guidelines and other requirements. Moreover, open-source variants of some applications also exclude functions that are present in their non-free versions, such as Photosphere panoramas in Camera, and a Google Now page on the default home screen exclusive to the proprietary version "Google Now Launcher", whose code is embedded within that of the main Google application.
Richard Stallman and the Free Software Foundation have been critical of Android and have recommended the usage of alternatives such as Replicant, because drivers and firmware vital for the proper functioning of Android devices are usually proprietary, and because the Google Play Store application can forcibly install or deinstall applications and, as a result, invite non-free software; although the Free Software Foundation has not found Google to use it for malicious reasons.
Google licenses their Google Mobile Services software, along with Android trademarks, only to hardware manufacturers for devices that meet Google's compatibility standards specified in the Android Compatibility Program document.
Alibaba Group defended the allegations, arguing that the OS was a distinct platform from Android primarily using HTML5 apps, but incorporated portions of Android's platform to allow backwards compatibility with third-party Android software.
Indeed, the devices did ship with an application store which offered Android apps; however, the majority of them were pirated. Android received a lukewarm reaction when it was unveiled in Although analysts were impressed with the respected technology companies that had partnered with Google to form the Open Handset Alliance, it was unclear whether mobile phone manufacturers would be willing to replace their existing operating systems with Android.
Nokia was quoted as saying "we don't see this as a threat," and a member of Microsoft's Windows Mobile team stated "I don't understand the impact that they are going to have.
Since then Android has grown to become the most widely used smartphone operating system [] [] and "one of the fastest mobile experiences available. As a result, it has been described by technology website Ars Technica as "practically the default operating system for launching new hardware" for companies without their own mobile platforms.
Android allows extensive customisation of devices by their owners and apps are freely available from non-Google app stores and third party websites. These have been cited as among the main advantages of Android phones over others.
Despite Android's popularity, including an activation rate three times that of iOS, there have been reports that Google has not been able to leverage their other products and web services successfully to turn Android into the money maker that analysts had expected.
Android has suffered from "fragmentation", [] a situation where the variety of Android devices, in terms of both hardware variations and differences in the software running on them, makes the task of developing applications that work consistently across the ecosystem harder than rival platforms such as iOS where hardware and software varies less.
For example, according to data from OpenSignal in July, there were 11, models of Android device, numerous different screen sizes and eight Android OS versions simultaneously in use, while the large majority of iOS users have upgraded to the latest iteration of that OS.
They maintain this forces Android developers to write for the "lowest common denominator" to reach as many users as possible, who have too little incentive to make use of the latest hardware or software features only available on a smaller percentage of devices.
Research company Canalys estimated in the second quarter of, that Android had a 2. By the third quarter of, Gartner estimated that more than half In July, Google said that, Android devices were being activated every day, [] up from, per day in May, [] and more than million devices had been activated [] with 4.
Android market share varies by location. In April Android had 1. As of February [update] , the Google Play store has over 2. Android devices account for more than half of smartphone sales in most markets, including the US, while "only in Japan was Apple on top" September—November numbers.
Three billion Android smartphones are estimated to be sold by the end of including previous years. According to Gartner research company, Android-based devices outsold all contenders, every year since According to StatCounter, which tracks only the use for browsing the web, Android is the most popular mobile operating system since August According to StatCounter, Android is most used on mobile in all African countries, and it stated "mobile usage has already overtaken desktop in several countries including India, South Africa and Saudi Arabia", [] with virtually all countries in Africa having done so already except for seven countries, including Egypt, such as Ethiopia and Kenya in which mobile including tablets usage is at While Android phones in the Western world commonly include Google's proprietary add-ons such as Google Play to the otherwise open-source operating system, this is increasingly not the case in emerging markets; "ABI Research claims that 65 million devices shipped globally with open-source Android in the second quarter of [], up from 54 million in the first quarter"; depending on country, percent of phones estimated to be based only on Android's source code AOSP, forgoing the Android trademark: According to a January Gartner report, "Android surpassed a billion shipments of devices in, and will continue to grow at a double-digit pace in, with a 26 percent increase year over year.
Gartner expected the whole mobile phone market to "reach two billion units in ", including Android. According to a Statistica 's estimate, Android smartphones had an installed base of 1.
In the second quarter of, Android's share of the global smartphone shipment market was According to an April StatCounter report, Android overtook Microsoft Windows to become the most popular operating system for total Internet usage.
In September, Google announced that Android had 1. Despite its success on smartphones, initially Android tablet adoption was slow. Due to the lack of Android tablet-specific applications in, early Android tablets had to make do with existing smartphone applications that were ill-suited to larger screen sizes, whereas the dominance of Apple's iPad was reinforced by the large number of tablet-specific iOS applications.
Despite app support in its infancy, a considerable number of Android tablets alongside those using other operating systems, such as the HP TouchPad and BlackBerry PlayBook were rushed out to market in an attempt to capitalize on the success of the iPad.
This approach, such as with the Dell Streak, failed to gain market traction with consumers as well as damaging the early reputation of Android tablets. An exception was the Amazon Kindle Fire, which relied upon lower pricing as well as access to Amazon's ecosystem of applications and content.
As of the end of, over According to StatCounter's web use statistics, as of August 15, , Android tablets represent the majority of tablet devices used in South America It can now be as integral to your mobile portfolio as Apple 's iOS devices are".
Charts in this section provide breakdowns of Android versions, based on devices accessing the Google Play Store in a seven-day period ending on October 2, just after release of Android Oreo.
In general, paid Android applications can easily be pirated. In, Google released a tool for validating authorized purchases for use within apps, but developers complained that this was insufficient and trivial to crack.
Google responded that the tool, especially its initial release, was intended as a sample framework for developers to modify and build upon depending on their needs, not as a finished piracy solution.
Both Android and Android phone manufacturers have been involved in numerous patent lawsuits. On August 12, , Oracle sued Google over claimed infringement of copyrights and patents related to the Java programming language.
They said that Android's Java runtime environment is based on Apache Harmony, a clean room implementation of the Java class libraries, and an independently developed virtual machine called Dalvik.
In December, Google announced that the next major release of Android Android Nougat would switch to OpenJDK, which is the official open-source implementation of the Java platform, instead of using the now-discontinued Apache Harmony project as its runtime.
Code reflecting this change was also posted to the AOSP source repository. In addition to lawsuits against Google directly, various proxy wars have been waged against Android indirectly by targeting manufacturers of Android devices, with the effect of discouraging manufacturers from adopting the platform by increasing the costs of bringing an Android device to market.
Google has publicly expressed its frustration for the current patent landscape in the United States, accusing Apple, Oracle and Microsoft of trying to take down Android through patent litigation, rather than innovating and competing with better products and services.
In, FairSearch, a lobbying organization supported by Microsoft, Oracle and others, filed a complaint regarding Android with the European Commission, alleging that its free-of-charge distribution model constituted anti-competitive predatory pricing.
Google has developed several variations of Android for specific use cases, including Android Wear for wearable devices such as wrist watches, [] [] Android TV for televisions, [] [] Android Auto for cars, [] [] and Brillo, [] later renamed Android Things, for smart devices and Internet of things.
The open and customizable nature of Android allows device makers to use it on other electronics as well, including laptops and netbooks, [] [] smartbooks, [] cameras, [] headphones, [] home automation systems, game consoles, mirrors, [] media players, [] and landline telephones.
In, Google demonstrated "Android Home", a home automation technology which uses Android to control a range of household devices including light switches, power sockets and thermostats.
Google, he said, was thinking more ambitiously and the intention was to use their position as a cloud services provider to bring Google products into customers' homes. Parrot unveiled an Android-based car stereo system known as Asteroid in, [] followed by a successor, the touchscreen-based Asteroid Smart, in Android comes preinstalled on a few laptops a similar functionality of running Android applications is also available in Google's Chrome OS and can also be installed on personal computers by end users.
In December, one reviewer commented that Android's notification system is "vastly more complete and robust than in most environments" and that Android is "absolutely usable" as one's primary desktop operating system.

This new series of courses from Vanderbilt University on Coursera is designed to help you launch your career as an Android developer. Although only a subset of total CyanogenMod users elected to report their use of the firmware, [9] on March 23, , some reports indicated that over 50 million people ran CyanogenMod on their phones.
In, the founder, Steve Kondik, obtained venture funding under the name Cyanogen Inc. The code itself, being open source, was later forked and its development continues as a community project under the LineageOS name.
CyanogenMod offered features and options not found in the official firmware distributed by mobile device vendors. Features supported by CyanogenMod included native theme support, [16] FLAC audio codec support, a large Access Point Name list, Privacy Guard per-application permission management application, support for tethering over common interfaces, CPU overclocking and other performance enhancements, unlockable bootloader and root access, soft buttons, status bar customisation and other "tablet tweaks", toggles in the notification pull-down such as Wi-Fi, Bluetooth and GPS, and other interface enhancements.
CyanogenMod did not contain spyware or bloatware, according to its developers. Soon after the introduction of HTC Dream named the "T-Mobile G1" in the United States mobile phone in September, a method was discovered to attain privileged control termed " root access " within Android's Linux-based subsystem.
In the following year, modified firmware for the Dream was developed and distributed by Android enthusiasts. One, maintained by a developer named JesusFreke, became popular among Dream owners.
In August, JesusFreke stopped work on his firmware and suggested users to switch to a version of his ROM that had been further enhanced by developer Cyanogen the online name used by Steve Kondik, a Samsung software engineer [21] called "CyanogenMod" user adaptations being often known as modding.
CyanogenMod grew in popularity, and a community of developers, called the CyanogenMod Team and informally "Team Douche" [23] made contributions. Within a few months, the number of devices and features supported by CyanogenMod blossomed, and CyanogenMod became one of the popular Android firmware distributions.
Similar to many open-source projects, CyanogenMod was developed using a distributed revision control system with the official repositories being hosted on GitHub.
A version of ADW. Launcher, an alternative launcher home screen for the Android operating system, became the default launcher on CyanogenMod 5. The launcher provides additional features not provided by the default Android launcher, including more customization abilities including icon themes, effects, and behavior, the ability to backup and restore configuration settings, and other features.
Initially, CyanogenMod releases were provided on a nightly, milestone, and "stable version" schedule; as of CyanogenMod 11 M6, the "stable" label will no longer be used, having been supplanted by "milestone" M-builds that are part of the CyanogenMod's rolling release development model.
Some unofficial builds for supported devices were listed in the CyanogenMod Wiki. CyanogenMod 7 firmware is based on Android 2. The custom portions of CyanogenMod are primarily written by Cyanogen Steve Kondik but include contributions from the xda-developers community such as an improved launcher tray, dialer, and browser and code from established open-source projects such as BusyBox in the shell.
CyanogenMod 7 development began when Google released Android 2. CyanogenMod version 8 was planned to be based on Android 3. However, as the source code for Honeycomb wasn't provided by Google until it appeared in the source tree history of its successor, Android 4.
CyanogenMod 9 is based on Google's Android 4. By the last days of November, some alpha versions had been distributed, in particular for the Samsung mobile phones Nexus S and Galaxy S.
On August 9, , after various betas and release candidates, CyanogenMod released the finished version of CyanogenMod 9. On August 29, , CyanogenMod released a minor update, version 9. Designed by user Ciao, Cid C.
With build M6 it was clarified that CyanogenMod would no longer be releasing final builds specially tagged "stable", but instead would utilize the rolling release model with M-builds representing a stable channel.
The latest version of CyanogenMod 11S for the One is The first nightly release of CyanogenMod 12, based on Android 5. A stable snapshot was released on June 25, , and a security patch snapshot was released on September 1, The first nightly release of CyanogenMod First stable builds were released on Due to the early release of Android 7.
The first experimental build of Cyanogenmod It is missing some of the signature features of CyanogenMod, however, and was considered a "work in progress".
In December the CyanogenMod developer group forked and re-branded the CyanogenMod code into a new project named LineageOS, which is built on top of CyanogenMod versions 13 and Rumors of plans to commercialize CyanogenMod, as well as the subsequent announcement of Cyanogen Inc.
Several CyanogenMod developers raised concerns that developers who had provided their work in the past were not being appropriately acknowledged or compensated for their free work on what was now a commercial project, further that the original ethos of the community project was being undermined and that these concerns were not being adequately addressed by Cyanogen Inc.
In response, Steve Kondik affirmed commitment to the community, stating that the majority of CyanogenMod historically did not use GPL but the Apache licence the same license used by Google for Android, and dual licensing was being proposed in order to offer "a stronger degree of protection for contributors Focal is a special case— it has to be GPL because [ This is a very common licensing model in the open-source world.
But none of this matters. Developer Entropy also observed that CyanogenMod was legally bound by its position to make some of the firmware changes, because of the Android license and marketing conditions "CTS terms" , which specify what apps may and may not do, and these were raised in part by Android developers at Google informally speculatively as a result of perceptions of CyanogenMod's high profile in the market.
In his blog post on Cyanogen's funding, venture funder Mitch Lasky stated: In January, it was reported that Microsoft had invested in Cyanogen, and that this might be part of a strategy to create an Android version that worked well with Microsoft platforms.
In July it fired around 30 of its staff and management, including its product head, and closed their Seattle office other offices were described as "gutted" , as part of a strategic change by the newly employed Chief Operating Officer Lior Tal.
Media analysis focused on dubious management decisions at Cyanogen Inc. In the company abruptly notified its existing partner OnePlus — who used CyanogenMod for its phones and had just launched models in India — that it had reached an exclusive agreement covering India with another supplier, leading to an acrimonious breakup of their relationship, which was described in the media as "practically screwing over" and "betraying" OnePlus and a "surprisingly childish" move; OnePlus was banned from selling in India as a result.
A day after leaving, Steve Kondik wrote a blog post in which he stated that in hindsight, he had trusted and hired "the wrong people", who had not shared a common vision, and that he had ended up unable to prevent the failure of the company and the forming of a "new team" in its place.
He drew attention to his own part in the failure, the loss of rights to the "CyanogenMod" name by the community, and to the rift in perception among Android developers "The rest of the ROM community seems to be highly dependent on us, but simultaneously wants us dead.
How on earth do you fix this? On December 23, , Cyanogen Inc. He stated that while "that this most recent action from [Cyanogen Inc. Early responses of tablet and smartphone manufacturers and mobile carriers were typically unsupportive of third-party firmware development such as CyanogenMod.
Manufacturers expressed concern about improper functioning of devices running unofficial software and the related support costs. As a result, technical obstacles including locked bootloaders and restricted access to root permissions were common in many devices.
However, as community-developed software has grown more popular [95] [96] [ not in citation given ] and following a statement by the U. Library of Congress that permits "jailbreaking" mobile devices, [97] manufacturers and carriers have softened their position regarding CyanogenMod and other unofficial firmware distributions, with some, including HTC, [98] Motorola, [99] Samsung [] [] and Sony Ericsson, [] providing support and encouraging development.
As a result of this, in the need to circumvent hardware restrictions to install unofficial firmware lessened as an increasing number of devices shipped with unlocked or unlockable bootloaders, similar to the Nexus series of phones.
Device manufacturers HTC [94] and Motorola announced that they would support aftermarket software developers by making the bootloaders of all new devices unlockable, although this still violates a device's warranty.
Phone manufacturers have also taken to releasing "developer editions" of phones that are unlocked. These packages were included with the vendor distributions of Android, but not licensed for free distribution.
After Google sent a cease and desist letter to CyanogenMod's chief developer, Steve Kondik, in late September demanding he stop distributing the aforementioned applications, development ceased for a few days.
Following a statement from Google clarifying its position [] and a subsequent negotiation between Google and Cyanogen, it was resolved that the CyanogenMod project would continue, in a form that did not directly bundle in the proprietary "Google Experience" components.
On September 28, , Cyanogen warned that while issues no longer remain with Google, there were still potential licensing problems regarding proprietary, closed-source device drivers.
Before installing an application, the Google Play store displays a list of the requirements an app needs to function. After reviewing these permissions, the user can choose to accept or refuse them, installing the application only if they accept.
An opt-in system is used instead, in which users are prompted to grant or deny individual permissions to an app when they are needed for the first time. Applications remember the grants, which can be revoked by the user at any time.
Permissions can still be revoked for those apps, though this might prevent them from working properly, and a warning is displayed to that effect. Nova wrote that "The Android operating system deals with software packages by sandboxing them; this does not allow applications to list the directory contents of other apps to keep the system safe.
By not allowing the antivirus to list the directories of other apps after installation, applications that show no inherent suspicious behavior when downloaded are cleared as safe. The study by Fraunhofer AISEC, examining antivirus software from Avast, AVG, Bitdefender, ESET, F-Secure, Kaspersky, Lookout, McAfee formerly Intel Security, Norton, Sophos, and Trend Micro, revealed that "the tested antivirus apps do not provide protection against customized malware or targeted attacks", and that "the tested antivirus apps were also not able to detect malware which is completely unknown to date but does not make any efforts to hide its malignity".
In August, Google announced Android Device Manager renamed Find My Device in May, [] [] a service that allows users to remotely track, locate, and wipe their Android device, [] [] with an Android app for the service released in December.
The source code for Android is open-source: Google publishes most of the code including network and telephony stacks under the non-copyleft Apache License version 2. Associated Linux kernel changes are released under the copyleft GNU General Public License version 2, developed by the Open Handset Alliance, with the source code publicly available at all times.
Typically, Google collaborates with a hardware manufacturer to produce a flagship device part of the Nexus series featuring the new version of Android, then makes the source code available after that device has been released.
The reason, according to Andy Rubin in an official Android blog post, was because Honeycomb was rushed for production of the Motorola Xoom, [] and they did not want third parties creating a "really bad user experience" by attempting to put onto smartphones a version of Android intended for tablets.
These applications must be licensed from Google by device makers, and can only be shipped on devices which meet its compatibility guidelines and other requirements.
Moreover, open-source variants of some applications also exclude functions that are present in their non-free versions, such as Photosphere panoramas in Camera, and a Google Now page on the default home screen exclusive to the proprietary version "Google Now Launcher", whose code is embedded within that of the main Google application.
Richard Stallman and the Free Software Foundation have been critical of Android and have recommended the usage of alternatives such as Replicant, because drivers and firmware vital for the proper functioning of Android devices are usually proprietary, and because the Google Play Store application can forcibly install or deinstall applications and, as a result, invite non-free software; although the Free Software Foundation has not found Google to use it for malicious reasons.
Google licenses their Google Mobile Services software, along with Android trademarks, only to hardware manufacturers for devices that meet Google's compatibility standards specified in the Android Compatibility Program document.
Alibaba Group defended the allegations, arguing that the OS was a distinct platform from Android primarily using HTML5 apps, but incorporated portions of Android's platform to allow backwards compatibility with third-party Android software.
Indeed, the devices did ship with an application store which offered Android apps; however, the majority of them were pirated. Android received a lukewarm reaction when it was unveiled in Although analysts were impressed with the respected technology companies that had partnered with Google to form the Open Handset Alliance, it was unclear whether mobile phone manufacturers would be willing to replace their existing operating systems with Android.
Nokia was quoted as saying "we don't see this as a threat," and a member of Microsoft's Windows Mobile team stated "I don't understand the impact that they are going to have.
Since then Android has grown to become the most widely used smartphone operating system [] [] and "one of the fastest mobile experiences available. As a result, it has been described by technology website Ars Technica as "practically the default operating system for launching new hardware" for companies without their own mobile platforms.
Android allows extensive customisation of devices by their owners and apps are freely available from non-Google app stores and third party websites. These have been cited as among the main advantages of Android phones over others.
Despite Android's popularity, including an activation rate three times that of iOS, there have been reports that Google has not been able to leverage their other products and web services successfully to turn Android into the money maker that analysts had expected.
Android has suffered from "fragmentation", [] a situation where the variety of Android devices, in terms of both hardware variations and differences in the software running on them, makes the task of developing applications that work consistently across the ecosystem harder than rival platforms such as iOS where hardware and software varies less.
For example, according to data from OpenSignal in July, there were 11, models of Android device, numerous different screen sizes and eight Android OS versions simultaneously in use, while the large majority of iOS users have upgraded to the latest iteration of that OS.
They maintain this forces Android developers to write for the "lowest common denominator" to reach as many users as possible, who have too little incentive to make use of the latest hardware or software features only available on a smaller percentage of devices.
Research company Canalys estimated in the second quarter of, that Android had a 2. By the third quarter of, Gartner estimated that more than half In July, Google said that, Android devices were being activated every day, [] up from, per day in May, [] and more than million devices had been activated [] with 4.
Android market share varies by location. In April Android had 1. As of February [update] , the Google Play store has over 2. Android devices account for more than half of smartphone sales in most markets, including the US, while "only in Japan was Apple on top" September—November numbers.
Three billion Android smartphones are estimated to be sold by the end of including previous years. According to Gartner research company, Android-based devices outsold all contenders, every year since According to StatCounter, which tracks only the use for browsing the web, Android is the most popular mobile operating system since August According to StatCounter, Android is most used on mobile in all African countries, and it stated "mobile usage has already overtaken desktop in several countries including India, South Africa and Saudi Arabia", [] with virtually all countries in Africa having done so already except for seven countries, including Egypt, such as Ethiopia and Kenya in which mobile including tablets usage is at While Android phones in the Western world commonly include Google's proprietary add-ons such as Google Play to the otherwise open-source operating system, this is increasingly not the case in emerging markets; "ABI Research claims that 65 million devices shipped globally with open-source Android in the second quarter of [], up from 54 million in the first quarter"; depending on country, percent of phones estimated to be based only on Android's source code AOSP, forgoing the Android trademark: According to a January Gartner report, "Android surpassed a billion shipments of devices in, and will continue to grow at a double-digit pace in, with a 26 percent increase year over year.
Gartner expected the whole mobile phone market to "reach two billion units in ", including Android. According to a Statistica 's estimate, Android smartphones had an installed base of 1. In the second quarter of, Android's share of the global smartphone shipment market was According to an April StatCounter report, Android overtook Microsoft Windows to become the most popular operating system for total Internet usage.
In September, Google announced that Android had 1. Despite its success on smartphones, initially Android tablet adoption was slow. Due to the lack of Android tablet-specific applications in, early Android tablets had to make do with existing smartphone applications that were ill-suited to larger screen sizes, whereas the dominance of Apple's iPad was reinforced by the large number of tablet-specific iOS applications.
Despite app support in its infancy, a considerable number of Android tablets alongside those using other operating systems, such as the HP TouchPad and BlackBerry PlayBook were rushed out to market in an attempt to capitalize on the success of the iPad.
This approach, such as with the Dell Streak, failed to gain market traction with consumers as well as damaging the early reputation of Android tablets. An exception was the Amazon Kindle Fire, which relied upon lower pricing as well as access to Amazon's ecosystem of applications and content.
As of the end of, over According to StatCounter's web use statistics, as of August 15, , Android tablets represent the majority of tablet devices used in South America It can now be as integral to your mobile portfolio as Apple 's iOS devices are".
Charts in this section provide breakdowns of Android versions, based on devices accessing the Google Play Store in a seven-day period ending on October 2, just after release of Android Oreo.
In general, paid Android applications can easily be pirated. In, Google released a tool for validating authorized purchases for use within apps, but developers complained that this was insufficient and trivial to crack.
Google responded that the tool, especially its initial release, was intended as a sample framework for developers to modify and build upon depending on their needs, not as a finished piracy solution.
Both Android and Android phone manufacturers have been involved in numerous patent lawsuits. On August 12, , Oracle sued Google over claimed infringement of copyrights and patents related to the Java programming language.
They said that Android's Java runtime environment is based on Apache Harmony, a clean room implementation of the Java class libraries, and an independently developed virtual machine called Dalvik.
In December, Google announced that the next major release of Android Android Nougat would switch to OpenJDK, which is the official open-source implementation of the Java platform, instead of using the now-discontinued Apache Harmony project as its runtime.
Code reflecting this change was also posted to the AOSP source repository. In addition to lawsuits against Google directly, various proxy wars have been waged against Android indirectly by targeting manufacturers of Android devices, with the effect of discouraging manufacturers from adopting the platform by increasing the costs of bringing an Android device to market.
Google has publicly expressed its frustration for the current patent landscape in the United States, accusing Apple, Oracle and Microsoft of trying to take down Android through patent litigation, rather than innovating and competing with better products and services.
In, FairSearch, a lobbying organization supported by Microsoft, Oracle and others, filed a complaint regarding Android with the European Commission, alleging that its free-of-charge distribution model constituted anti-competitive predatory pricing.
Google has developed several variations of Android for specific use cases, including Android Wear for wearable devices such as wrist watches, [] [] Android TV for televisions, [] [] Android Auto for cars, [] [] and Brillo, [] later renamed Android Things, for smart devices and Internet of things.
The open and customizable nature of Android allows device makers to use it on other electronics as well, including laptops and netbooks, [] [] smartbooks, [] cameras, [] headphones, [] home automation systems, game consoles, mirrors, [] media players, [] and landline telephones.
In, Google demonstrated "Android Home", a home automation technology which uses Android to control a range of household devices including light switches, power sockets and thermostats.
Google, he said, was thinking more ambitiously and the intention was to use their position as a cloud services provider to bring Google products into customers' homes. Parrot unveiled an Android-based car stereo system known as Asteroid in, [] followed by a successor, the touchscreen-based Asteroid Smart, in Android comes preinstalled on a few laptops a similar functionality of running Android applications is also available in Google's Chrome OS and can also be installed on personal computers by end users.
In December, one reviewer commented that Android's notification system is "vastly more complete and robust than in most environments" and that Android is "absolutely usable" as one's primary desktop operating system.
