My Android emulator beachballs on startup almost every time I try to use it. I'm currently using Android Studio 0.2.0 build 130.737825 on OSX 10.8.4. It seems like it will launch into Android once or twice, then if I close and reopen, it hangs on the black screen before the Android splash screen. At this very moment, it's been hung for about 15 minutes. I don't see anything useful happening in Console. And Android Studio is fine. It's just the emulator that hangs.
The android emulator is pretty much unusably slow. I recommend using genymotion instead of the emulator. Genymotion runs the android device as a virtual machine, so it's basically like having a real device running. And it's super fast.
Android's emulator is slower than Apple's simulator. you can refer to here to know why. But you can actually enhance the virtual device(x86 not ARM) performance, if you install Intel x86 Emulator Accelerator(HAXM) which can be found in Android SDK Manager.

I am new to android studio, and I do not have an android phone, so the first thing I actually tried to do is to try out the emulator before I get any further into android studio, but I am facing alot of problems.
When I press on the RUN button, I do find a "Nexus 5X API 27 X86" by default, when I run it, well here comes the problems. Sometimes it runs and opens properly, but without being able to find my app on the device, sometimes the app opens automatically. The device is always so slow, most of the times when I try to open an app, I get a msg "APP(google most of the time) has stopped working" or "Android is starting.." out of nowhere, and that same msg sometimes pops out automatically when I first run the emulator. Sometimes I get "Application Installation Failed" error, found some solutions saying to trun off instant run, I turned it off and I still get the error sometimes.
Generally, it is just impossible to start coding with such device, I had an android phone before and it was much easier.
As far as I know, my laptop should easily support both the android studio and the emulator.
One more thing, whenever I try to set up a new device on kitkat or something, the device doesnt come alive, just a stuck black screen with a logo in the middle.
My laptop:
Intel Core i7-5500U 2.4GHz
4gb RAM + 8gb RAM
Nvidia GeForce 920m - 2gb
64bit
And yeah, HAXM is installed.
Android Studio 3.0.1
Any assistance would be appreciated.
You can try genymotion if you feel android emulator is slow. https://www.genymotion.com/
you can find the difference between the android emulator and genymotion.
android genymotion vs emulator
Emulator's now is much faster and better then genymotion,just create your own device going to avd manager and then try to run it,one more thing , did you turn on intel virtualization in bios ?
I am attempting to Use Fast Deployment to quickly test my Android App in the emulator. I am doing this because, as you probably know, building and testing an app on the emulator is incredibly slow and quite frustrating so I need to speed this up.
PS: If you have any advice on how you can deploy and run an app on an emulator in under 30 seconds I'd greatly appreciate it. My app is tiny and simple so it shouldn't take bloody 1.5 mins to run on the emulator?
The deployment is failing and giving me the error:
Xamarin.AndroidTools.AndroidDeploymentException:
FastDevDirectoryCreationFailed at
Xamarin.AndroidTools.AndroidDeploySession.WaitForRemoteDirCreation(String
destinationPath, CancellationToken token) at
Xamarin.AndroidTools.AndroidDeploySession.InstallAssemblies(String

at Xamarin.AndroidTools.AndroidDeploySession.Run(CancellationToken
token) at
Xamarin.AndroidTools.AndroidDeploySession.RunLogged(CancellationToken
token) at
Xamarin.AndroidTools.AndroidDeploySession.Start(CancellationToken
token)
How I can fix this error? And successfully Use Fast Deployment and deploy it to the emulator? How you speed up Android emulator deployment and testing?
Relevant information:
On Windows 8.1 Surface Pro 2 (4gb ram)
Using VS2013 Professional
The Android emulator is a Nexus (API 21) CPU = Intel ATOM x86. I am using this because Xamarin suggests this to speed up deployment.
The project uses Xamarin and MVVM Cross
If I deploy to a different emulator using Use Fast Deployment I get no deployment error but when the app runs it crashes immediately with: Unfortunately 'app' has stopped
Though I don't know what fast deployment is, I can however suggest a very fast emulator - Genymotion. I use it for my app and it deploys in under 10 seconds. Below is the link. https://www.genymotion.com/
A few quick points, the document recommends using the Xamarin Android Player, so I would recommend using that too. If you don't really need to use a simulator, then deploying to device is also nice and quick too. That said, this scenario should work, is it possible to send over some more details on your issue to contact#xamarin.com and someone should be able to help (and mention I sent your issue this way?
If Genymotion doesnt work for you try Andy emulator. If both are still too slow for you try using xamarin studio with genymotion
Visual Studio Emulator for Android
also works very well. It uses hyper-V, so no need to install VirtualBox like GenyM, which can cause conflicts with hyper-V if you're doing windows developement at the same time.
For me, this error just randomly started appearing when trying to build from Visual Studio. It seems like something was wrong with the phone.
I cleared the phone's cache and I was able to install the app through Visual Studio again. To clear a phone's cache, you usually need to turn it off and then turn it back on in "Recovery booting". Usually this means holding some combination of volume button/power button/main button. Once booted in this mode, you should be able to see a "clear cache" option and then restart.
For my work project I received I'd need to use the emulator as the company does not have a 5.0 device yet.
But when I try to start it, it loads infinitely. I've checked the logs, and it reboots because of this: http://pastebin.com/yCjiAaPR
Has anyone ran into this issue and solved it yet?
PS: Latest Android SDK, fresh updated! Computer is a Lenovo G50-70, target is ARMv7 with 2gb ram.
Use the GenyMotion emulator instead it is VERY fast, very easy .If you insist to use it then this can be due to the reason that you don't have enough RAM. also try this solution if it still don't work
android emulator won't start
Hi I am new in android and started to learn
I have Windows 7 PC, with 2.33GHz Intel Core I3.
I am using Eclipse SDK
Version: 4.2.2
Build id: M20130204-1200
Android Development Toolkit
Version: 22.6.2.v201403212031-1085508
I have tried to run simple hello world program and don't know but emulator is showing just
android----- android, it's not even starting it's main windows
can anybody help me how to resolve that issue
I personally suggest you instead of use of Android Emulator use
GenyMotion or BlueStacks in both of them
for just android application development and testing Genymotion is the best best and the best
first time emulator start takes soo long, i mean first time ever, and first time in day.
however, you can check the Logcat and see what is going on,
you can view logcat (if not already appearing) by going to
Window -> Show View -> Logcat
if does not appear in the list, click other, and search for logcat.
once emulator started it will show log in logcat window.
it might be useful.
You should try the x86 version of the emulator, with HAXM enabled (if your computer supports Intel VT) it will be much faster than the ARM version.
Then, when creating a new device, choose the Intel Atom (x86) option for its CPU.
This is the guide I followed, looks like things haven't changed much since then.
You just wait..It takes a lot of time for the emulator to start..Make sure that snapshot is checked while creating the new avd and next time when you launch the avd make sure the Launch from snapshot checkbox is checked..
Android Emulators are very slow and buggy try GenyMotion it is fastest Emulator !
Every Android Developer should have.
I am trying to test a simple status bar notification program on Android 3.0 emulator.
When I try to run my application from eclipse, sometimes either I see a message that apk can't be installed when I check the DDMS log, I see java outOfMemory error. Though my application is fairly simple just one java file.
Sometimes when I launches my emulator it shut down my windows completely. I tested this on Windows XP and Ubuntu as well. In Ubuntu too when emulator was about to launch completely and showing home page my OS crashes.
Any other version of Android works well on my PC like 2.2, 2.3. I see this issue only with 3.0 (honecomb) version. Any resolution to this?
Thanks

Well when making an AVD from the AVD Manager , assign it maybe 200 -500 mb and this issue will be resolved.
I have noticed the resource usage while running 3.0 is much more than 2.3 and below. The error you are getting refers to the emulator/eclipse needing more memory not your application. How much memory and CPU do you have?
