When I start an emulator from Android studio, it closes immediately and it shows these messages in the Android studio event log
Previously, I had Genymotion installed, but the problem still occurs after I have successfully removed it (along with Virtual Box) from my computer.
I have VMware on my computer, but this was never a problem for successfully running an Android Emulator.
I have tried all of the proposed solutions on the internet (including reinstall of Android studio, update HAXM...), but nothing works.
Maybe it is due to the fact that your pc doesn't have much memory or disk space to run android emulator.Please check this if it helps.
Check what 'adb devices' shows you.
Seems like you still have some parallel instance running
May be it depends on your computer features.After you open a place where android studio is set up,everything might be okey

I have been working on a particular Android application for sometime and have been able to run these apps via Android Studio quite fine before but since applying a recent update I have not been able to run the app via Android studio because of the following error:
android.os.TransactionTooLargeException
Error: Could not access the Package Manager. Is the system running?
I have tried to troubleshoot this issue by connecting via a different TCP/IP instead of through USB (thinking it was a cable fault of sorts), reinstalling ADB, removing the ADB driver and restarting Android Studio, and all of the above yielded the same error when trying to run the app from Android Studio.
The update that was applied was the addition of the YouTube Android Player to a fragment. The fragment that contains YouTube Player was added to FragmentManager of the parent Activity during the onCreate method of this fragment. Could this be the problem? Or am I looking in the wrong place
Any insight would be appreciated.
You may have gotten this error while attempting to run an Android application on an emulator or device using Android Studio. The most common cause of this error is simple as stated in this link: You have to manually unlock your Android Virtual Device by swiping the "lock" icon on the screen. Security measures prevent the emulator from letting you connect the debugger before doing this. Make sure also that you are running Android Studio version above 0.3.2 or the latest version. There was some issue reported in AS 0.3.2. You can update it from Help >Check for update.
Found this thread which states that it might be an issue with your emulator not with Android Studio. Maybe you are trying to install application before even the emulator started properly. Wait till the home screen appears in the emulator before trying to install any application.
Also try to install any apk in Emulator from command line
Steps to install
Go to $Android_SDK_DIR\platform-tools, right click there keeping shift key pressed and Chose "Open Command Window here".
Run command adb devices to make sure yout emulator is running properly. It will show all your running emulators.
Now if emulators are showing properly, type the command adb install YOUR_FULL_APK_PATH , YOUR_FULL_APK_PATH is of any .apk
file path in your system.
You need to wait for the emulator to full start which may take a few minutes. Once it is fully started (UI on the emulator will change), it should work. You will need to restart the app after the emulator is running and choose the running emulator when prompted. You can check on this bug report the full details.
Hope this helps!
I'm not sure, but check if this works.
menu>> tools>>Android>>Enable ADB integration check it
I am using Genymotion for personal use to test my apps.However, the emulator opens up, displays everything fine.As soon as I run my app, it hangs or crashes.Same is happening when I use default android emulator.Also its taking quite too long to open my default emulator.I checked HAX on console and it is running fine.My system RAM is 8Gb.It appears to me some memory like issue but cannot figure it out exactly.
I had the same problem with ...
The solution that worked for me with x86 emulator was to update HAXM with the last version and to restart my computer.

may be this also works for you
The root cause was a missing video driver (the vanilla Microsoft one wasn't enough). I was working with a cobbled-together frankenbox and found it useful to follow the instructions on finding the right driver here:

I create blank xamarin android project without add any code when i debug this project debugging without problem but when i run app with visual studio emulator for android emulator is running but not starting my app and deploy failed and don't show me error
why ?
please help me
I had the same issue. VS 2015 can launch the VS emulator but can't deploy the app.
I was able to solve the issue like this:
Launch the emulator (F5 in VS, then cancel the deployment using the Build/Cancel menu)
Click on the chevron icon (») in the toolbar to the right of the emulator
Select the Network tab
Locate the preferred network ip address
Back in VS, click on the Open Adb Command Prompt toolbar button
Type adb connect [the emulator ip address]
Press F5 again in VS
Looks like a VS bug to me.
I had the same issue. It turned out the root cause was that the VS Emulator couldn't find adb.exe.
When that happens it won't connect to the emulator unless you do the manual connection following the steps CSharpRocks gives. The emulator also won't be listed under "adb devices".
The fix for me was to reinstall the Android SDK, using the Windows EXE based installer (not the zip installer). The EXE installer sets the HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Android SDK Tools key, Path value, in the registry, pointing to the Android SDK root directory.
The VS Emulator uses that registry setting (or the Android Studio install registry setting) to find the SDK, assuming you didn't install the Android SDK with Visual Studio itself. With that, it should be able to find adb.exe and work.
Have a look here:
Xamarin Forms Android App Crashes Running Debug with VS Android Emulator
Start the Hyper-V manager
Select the emulator you are trying to use
Right-click, hit settings
Click processor
Click Compatibility
Set checkbox “Migrate to a physical computer with a different processor version”
I'm having a very similar issue. I have found two different kind-of-work-arounds, but have not yet figured out a full solution.
Start the emulator before trying to deploy to it
Launch the Visual Studio Emulator for Android application from the start menu.
Launch one of the available emulators via the green arrow
Attempt to again launch your application from visual studio, selecting the VS Emulator N-inch... emulator from the drop down menu
For me for some reason the app still doesn't "launch" on the emulator, although it is installed. So I have to open the application menu and select my app. Additionally it will usually crash the first several times I try to open it, but eventually displays my single default label, Welcome to Xamarin Forms!.
Run the application in Ad-Hoc mode
Before running the application, change the solution configuration (from the top toolbar next to the green "run" button) to Ad-Hoc.
The problem with both of these methods though is that I'm still not able to actually debug an application. I can run it, but my breakpoints are ignored and I think that will make finding bugs difficult once I actually start to write a real application.
I hope to update this answer once I figure out an actual solution.
I had the same problem yesterday. The problem appeared (probably) because I tried to start development after a long break. I updated VS and everything, but faced many issues.
Eventually you need to start fresh
Make sure SDK for emulator points to the right place (HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Android SDK Tools)
Run Visual Studio with Administrator privileges
Go to Hyper-V Manager and delete ALL Virtual Switches - let the system recreate them when needed. It will do it properly
Delete all existing emulators and recreate them in Visual Studio. I even found a comment to name them without spaces - not sure if it is needed, but wouldn't hurt.
Doing all this helped me. But I was on the verge of reinstalling Windows 10 clean. I think lots of things and configuration changed and are no longer compatible.
Try it enabling Hyper-V and using a Visual Studio Emulator from android; that worked for me after a lot of attempts and research
I had the same issue but in my case it was not the registry. After doing a release build, I deployed the app to the emulator device in release mode which pushes the app to the device and then effectively "disconnects". This leaves a version of the app on the device which seems to block further attempts at debugging or deploying.
I solved it by starting the emulator, going to "settings -> apps" and manually uninstalling my app. Then the next debug build & deploy worked again.
You could probably also manually start the emulator and say "wipe device" option so it starts fresh.
In VS2017, on a Windows10 machine, all I had to do to get the app to show up was turn off Mobile Data.
(swipe down or use settings, then click Mobile Data and confirm to turn it off).
After I turned it back on, I could access the app. Before doing this, it always seemed that the emulator ran, but wouldn't run the app.
... no idea why this worked, but I'm posting it here in case it helps someone.
During my troubleshooting process, I also looked at these articles:

I had such issues before with the android SDK emulator, now I'm using Genymotion emulator instead of it, it is more light and faster and will be detected automatically by you VS once launched.
you can download the free version from here : https://www.genymotion.com/
and also you can download any device emulator.
When I try to launch Android emulator, it crashes on Mac OS X. It was working some time ago, but now it isn't and I don't have an idea why.
Crash log: http://pastebin.com/04MjCqaS
Terminal log in verbose mode: http://pastebin.com/L6y6rUr0
Same issue here, I'm running a mac mini with 8GB of RAM and MacOS Lion. It used to work with the old AVD with some random crashes every now and then but since the last update to APi 17 it's a pain in the neck.
The ADT bundle doesn't work at all. After tweaking the memory limits on eclipse.ini file it throws random memory errors. Also it's not been able to download and install the m2e (maven to eclipse) plugin.
I moved to IntelliJ and I'm able to launch AVD manager but none of the "old" created devices work. If I create a new one and I launch it it works until I close it, then I have to restart the Mac and create a new device. Also it randomly shows errors when I want to delete those old created virtual devices.
Also the DDMS fails to start. I launch it, shows its icon on the Dock but it doesn't respond until I force close.
What a Nightmare.
** EDIT **
I found at android dev bug tracker this issue when you're running 2 screens: here
This is happening to me with the android emulator. I solved it like this:
cd ~/.android/avd
ls *.avd
Now choose the emulator that is crashing and
cd name_of_the_emulator.avd
touch emulator-user.ini
vi emulator-user.ini
And now reset window.x, that's window.x=0
exit and run the emulator.
If you move and close the emulator to the secondary screen it will crash the next time you want to run it.
Kill your Docker process
One problem I have seen multiple time is with Docker. Android Emulator crashes when Docker is running on Mac.
I was following the PhoneGap "Getting Started" guide for Android, and when I got to "Deploy to Emulator," after I created a new AVD, my Mac would crash and reboot. I stumbled on this thread, but thought it worth mentioning that what actually solved the problem for me was an Intel patch for the Hardware Accelerated Execution Manager located here: http://software.intel.com/en-us/articles/intel-hardware-accelerated-execution-manager
This is because Android SDK use some deprecated libraries of Mac OS X. I have the same problem (sometimes even kernel panic) before I start use android device. Maybe in future versions of Android SDK this problem will be fixed.
I just updated the Android SDK manager to the latest Android 4.2 (API 17) level updates, and now all my old AVD's crash. The newly created one using API 17 works, however.
I have the same issue. You can try to create a new AVD with the appropriate API level. I am able to run these the first time(s) after creating. That seems to be a memory error.
My AVDs are able to run the first time after reboot. After this they keeps crashing.
I had the same issue using mac 10.6 and 2 monitors one through a usb adapter to HDMI.
I have tried all of this suggestions and nothing did work.
I ended up creating a new user into my mac and with the same android sdk and same eclipse with a new workspace did work.
I'm not sure whether just creating a new workspace would do the tweak, I didn't try it.
for those who come across to this annoy issue worth to try it before switch to a new account.
You can delete your emulators from ~/.android/avd
Then create new emulators.
I am just beginning to use Eclipse for Android applications. After updating my Android SDK i can't run my projects on device anymore. It says "Installing app.apk..." but nothing happens. Installing my app with adb without eclipse works, where could be an Issue? I reinstalled SDK and Eclipse twice.
Try unistalling the application from the phone before re-installing it. Also make sure you have the option to allow non-market apps checked in your phone settings --> applications.
Is it getting stuck at a particular percentage? If that is the case, the solution was to keep the virtual device running before you attempt to run the project.
I had the same problem on my computer. Android sdk on eclipse doesn't work well with windows x64.
So to launch the application you have to kill the adb process. Wait that adb restart and launch one more time.
