Android emulators: Difference between revisions

'''[[wikipedia:Android (operating system)|Android]]''' is a mobile operating system developed by Google and the Open Handset Alliance. It was originally developed in secret before launching in 2008 as a competitor against Apple's [[iOS emulators|iPhone]]. While other mobile operating systems had been made throughout the years, none have emerged in terms of market share nearly as much as Android.

Android is like a Linux distribution in that it uses the Linux kernel to facilitate communication with the hardware and manage processes on the system. Unfortunately, the similarities end there as Android uses an entirely different toolset from standard Linux distributions and no support is given for running it on PCs. (Software development on Android is also nothing like Linux development as apps are compiled into architecture-specific <code>APK</code>s via Java which, like IPA files on [[iOS emulators|iOS]], are specially designed Zip files. They may be occasionally coupled with <code>OBB</code> files). While Android can technically run Linux binaries, doing so requires superuser privileges that Android does not provide by default. For many devices, you can expect to see a custom ROM that has an integrated su binary (or a means to install it easily, such as a custom recovery) but not all devices have one.

However, the Linux kernel is flexible enough that it can be emulated well unlike iOS, older cell-phone models, and older Japanese Galapagos mobile phones. While Android natively supports mice<ref group=N>If you have an Android device you can confirm this by connecting a Bluetooth mouse or a USB mouse via a USB On-the-Go adapter.</ref>, most apps expect users to have a touchscreen, so Android emulators will usually default to emulating touchscreen presses like [[Nintendo DS emulators|DS emulation]] (though it can be less than ideal in many cases). The host's keyboard may often emulate the button controller add-ons, and some emulators support [[Xbox 360 emulators|Xbox 360]] controllers as well with some more tweaks.

'''Important Note:''' These emulators are usually closed source and while they're distributed for free, their devs look for roundabout ways to monetize them. One such high profile case was BlueStacks. Make sure to check if there are pre-installed apps on your emulator (and disable them), monitor your Internet connection download caps and processor activity to detect any abnormal activity (and block domains accordingly if the need arises) and avoid as much as possible giving sensitive account data (just in case it's key-logged). Besides basic safety, these precautions often make impacted emulators run much faster when the adware services and apps are turned off. Windows subsystem for Android is an exception, as Microsoft made it and monetizing comes from the Windows copy you brought.  

The VM column describes what backend technology the emulator uses. Emulators labeled with "VirtualBox" sometimes needs the user to install [https://www.virtualbox.org/ Oracle VM VirtualBox]. Usually, it is installed automatically.

:A closed-source Android emulator with hardware-accelerated 3D graphics and USB host support, available for Windows, macOS, and Linux. In its latest versions, it has pretty good compatibility with commercial games. It's a commercial product though, aimed at software developers and QA teams. You'll need to create an account and download the free non-commercial use license available. Except for pay-to-remove "free for personal use" watermark on the screen, paid builds to add features only useful for Android app developers.

Setting up the emulator itself is not too hard, but a bit of tinkering is required to add the Google Play store and [http://forum.xda-developers.com/showthread.php?t=2528952 ARM processor emulation] (what you need essentially here to play the commercial releases) as well as [https://groups.google.com/d/msg/genymotion-users/JpO8HR39PR0/NpSkrnsB8d8J Xbox 360 controller support]. Not noob-friendly, but if you're experienced enough with Android to know your way around a rooted filesystem it shouldn't be too hard.

'''Note as of November 25th, 2019''': The above paragraph is outdated and ARM Emulation has been broken in Genymotion for a while, so you can't use ARM apps unless you get a really old version.

:Also commercial with a free option (requires a google account). It's less good than Genymotion and doesn't handle USB cable emulation. Previous versions used to come with an installer with adware comes with junk apps within the emulator and has a non-intuitive uninstaller, but that's no longer the case today. It includes Google Apps by default, though you'll need to install a file manager to copy game cache when loading your own .apk files.

:An Android emulator also with good accuracy. When testing games along side Nox, LDPlayer shows to have better performance/compatibility with games.

Has good accuracy but forcefully uninstalls VirtualBox, so it cannot co-exist with Genymotion and Xamarin. It's not recommended because it will install hidden background services (xunlei.exe, and Thunder.exe, both by the Chinese company which developed Droid4x) that seed Chinese torrents constantly and they are a pain to uninstall or deactivate (in case you've already fallen for it, use Revo Uninstaller).

:Not recommended because it will install a [https://www.reddit.com/r/emulation/comments/8rq4fm/reminder_that_andyroid_mines_cryptocurrency/ cryptocurrency miner] on your system without asking or informing about this to the user. Just like Genymotion, Andy OS uses VirtualBox, but with a twist: if it detects an installed VirtualBox during installation, '''it will delete it''' and will refuse to work. Beware!

:Not to be confused with a [http://ds-duos.blogspot.com/ similarly-named Nintendo DS emulator] by Roor, is a relative newcomer to the Android emulation market, made by American Megatrends i.e. the very same people behind the BIOS/UEFI firmware your PC may be using. Emulation is modest at best, with games and apps such as [[DraStic]] struggling on lower-end hardware. And to top it all off, it isn't free either.

:Can open .apk files using the ARC Welder extension, though their emulation on PC is average at best. Here's a [http://docs.google.com/spreadsheets/d/1iIbxaftAu_ho5rv9fUlXSLTzwU6MbKOldsWXyrYiyo8/edit#gid=0 compatibility list] and a [https://www.reddit.com/r/chromeapks dedicated subreddit]. Google has announced [http://arstechnica.com/gadgets/2016/05/the-play-store-comes-to-chrome-os-but-not-the-way-we-were-expecting/ Play Store for Chrome OS], but it works on a different "container" technology that is embedded in the Chrome OS. In addition, Google will [http://blog.chromium.org/2016/08/from-chrome-apps-to-web.html discontinue Google Chrome apps on PC], so any major updates to ARC Welder for PC is unlikely.

:(Without the 'e' suffix) is a fast Android emulator that does not rely on VirtualBox or any similar technology. It isn't accurate though. While Google Play store can be installed with some tinkering, not many games can be installed (due to not faking device names) and will spawn multiple harmless-yet-annoying app_process.exe crashes. The official site is down since July 2016, so any updates are unlikely.

:An open-source project that aims to port the Android operating system to x86-based netbooks. Comes with Google Play and libhoudini (x86/ARM translation layer) installed. 3D acceleration works well both when installed directly on the machine as a local OS and also on VMware. VMware Player 15 supports emulating OpenGL ES 3 on the target and performance is quite good. VirtualBox 3d support is poor and probably won't work. Android x86 is continually being improved and can be tried fairly painlessly through VMware. Genymotion is (or at least used to be) a closed-source fork of Android x86, designed exclusively to be run on VirtualBox.

:A project that aims to run Android applications on Ubuntu distributions. Currently, it is on alpha state and only known to work on Ubuntu 16.04. Anbox requires custom kernel modules to run because unlike other emulators which emulate the whole Linux kernel, this one uses the host system's Linux kernel directly.

:A project by KDE that aims to run Android applications on Linux using KDE5 and Qt5 technology. The project is infancy state and only known to run on latest Kubuntu versions. It currently lacks ARM processor emulation, so not many games will run. It is however known to play [https://www.youtube.com/watch?v=9SC6c_ih_Ac Flappy Bird] and can show [https://www.youtube.com/watch?v=ju_R8ftiIp4 Spotify's login screen]. It uses modified [[QEMU]] to emulate the Android operating system. Last major update was March 2016 and seems abandoned.

:A newcomer to the Android emulation market. Not much is known about this because it required a minimum of $25/month subscription of main Xamarin products. The main Xamarin products were  [https://blog.xamarin.com/xamarin-for-all made available for free] after the purchase by Microsoft, but Xamarin Android Player was discontinued.

:A program that runs another copy of Android on the current Android system, which would be useful for running multiple copies of the same application simutaniously, running applications that rely on older/newer versions of Android system, testing out different Android system variations, or safely executing operations/applications that's likely to do harm to current system/user data.

:A Microsoft-developed Android emulator for Windows 10 Mobile included in several insider previews. It could run [https://www.reddit.com/r/windowsphone/comments/3gaoct/android_apps_that_work_on_win10_right_now/ a few applications], though apps required Google Play Services did not run or had issues. This project was reportedly [http://www.windowscentral.com/microsofts-project-astoria-delayed discontinued] in November 2015 and [http://www.winbeta.org/news/microsoft-confirms-the-death-of-project-astoria-focusing-on-other-bridges-instead its cancellation was confirmed] on February 2016, so the emulator is not included in more recent versions of Windows 10 Mobile.

Android is open source, but the Google Play Store has to be licensed from Google in order to incorporate it into a build, including Play Services and many other Google apps. That often means developers pay a fee that can trickle back to the user in some form (either through adware, privacy-invading trackers, or by selling the emulator as a commercial product). Custom ROMs for real Android devices on Android 4 and earlier used to bundle the Google Play Store but this changed with newer versions. The new method is to install a custom ROM and then install "GApps" through another service like [https://opengapps.org/ the Open GApps Project].

Many games often optimize and compile specifically for ARM processors, which prevents them from being executable on x86 CPUs, even when using a project like Android-x86. Some emulators like BlueStacks have ARM emulation by default; in others like Genymotion, it is possible to install an ARM emulator manually (though only on older versions as such functionality is broken in newer releases).

Some games take more aggressive measures to detect the presence of Custom ROMs (unofficial firmware) or Android emulators (like the ones listed in this page) in the variety of ways like checking for the existence or absence of system files in order to prevent the game from running in any unverified environments. These games are very difficult or plain impossible to play on emulators without resorting to cracked versions of the games.

There are many [[wikipedia:Fork_(software_development)|forks]] of Android, these go beyond a custom UI and are new OS's that use the Android code in addition to writing their own code. depending on how much (and what) new code, features and API's were added, will determine the effects they will have on Android emulation but if one is for sure, these forks are (most likely) going to cause some emulation issues.

Because it's possible to fork and created you're own Android-based OS, many developers have used Android to power their own commercial console. However, as mentioned before, just because it uses Android as a base does not mean they will all work properly on a normal Android emulator.

|Released in 2018 by Clementoni, the Clemstation is an "multimedia educational console" only sold in Italy that appears to be on a running custom version of Android. Because it's still being sold, it unknown how games will be made for it and when it well be discontinued, info on how many units have been sold so far not been released to the public.  

|Released in 2018 by Italian toy company Clementoni and sold exclusively in Italy, My Clem Box is an educational console with Wii-like motion controls. Because it's still being sold, it unknown how games will be made for it and when it will be discontinued. Info on how many units have been sold so far have not been released to the public.

|Released  in 2017.by Takara Tomy. The NEO Series are educational consoles only sold in Japan and appear to be using a custom version of Android. Because it's still being sold, it unknown how games will be made for it and when it well be discontinued, info on how many units have been sold so far not been released to the public.

|A console/media box hybrid manufactured by Nvidia. Has a lot of heavy-hitting titles such as Metal Gear Rising: Revengeance, Doom 3, Half-Life 2 etc.

|A failed microconsole that started from a Kickstarter project. The controller sucks and the games can be found elsewhere. Since the Ouya runs on Android, emulation is technically possible by extracting menu/application apk files and running them in an Android emulator or VM.

|A tiny console with the size of a USB thumb drive.  

|A console designed by Tencent, manufactured by multiple different manufacturers such as Lenovo and Skyworth. Designed to run cellphone games and simple emulators.
