For a while I was able to run my app in the android emulator that was installed with Android Studio.
I have since updated SDKs and installed some x86 emulators with SDK manager and now none of the emulators will run properly no matter what I do..
They won't run if I select the run button in android Studio and they won't run if I select the run button I AVD manager.
If I view windows task manager I can see the emulator starting up but they just crash before the emulator window appears.
So what do I do here? Uninstall bloody Android Studio and start over???? Because nothing else that I have googled on this problem works.
All the solutions others have proposed appear to be very vague and a result of random trial and error rather than inside knowledge.
I have tried deleting my emulators and creating new ones.
I have tried wiping data in AVD manager.
I have tried changing the SDK versions in the emulators.
I have tried switching between ARM and X86 system images.
I have tried switching between 'Software GLES' and 'Automatic'
None of them fixes the problem.
The emulators start up in task manager but crash before anything becomes visible while android studio waits in vane for the device to start up.

For some reason ever since I updated Android Studio to version 4.1, whenever I try to run the emulator I get this error:
Error while waiting for device: The emulator process for AVD Pixel_2_API_29 was killed.
I have tried reinstalling android studio, cold booting the device and literally everything I could think of.
newbie here but wanted to learn more about developing apps, so downloaded Android Studio to do an intro lesson and was frustrated by the same issue -emulator was "killed" before opening. Well, I think I saw a vague suggestion somewhere to uninstall Emulator using SDK Manager (SDK Manager - System Settings - Android SDK - SDK Tools), then reinstalling from same place (SDK Manager). Voila! It worked for me. The emulator works and I see my virtual device. As a newbie you can imagine how cryptic this all was for me, but it's one way to learn, I guess!
I have just uploaded my Android Studio version to 2.3, and I am now having problems testing my app in my emulator. It is a Nexus 5X emulator with Android 7.0 Nougat loaded on it (API 24), with an ABI: armeabi-v7a (I have an AMD processor, so to the best of my knowledge I can only use this). Before, it was a bit slow and would sometimes come up with a 'Not Responding' error, but clicking 'Wait' would always do the trick.
After the Android Studio update, when I press 'Run', it opens up & boots the emulator. However, once booted, it gets stuck on the "Launching App - Installing APKs" process. It probably shows that it is doing this for about 2 minutes, before stopping. It then shows "Launching Instant Run Service" for a few seconds. The green 'run' arrow then becomes active again, as if there is no emulator open. The emulator is open, but there is no app. If I click the green 'run' arrow with the emulator already open, it does a gradle build sync & then doesn't even attempt to launch the app/install APKs - it only says "Launching Instant Run Service" for a few seconds, even though nothing happens.
I have tried removing the emulator & recreating it, and I have also tried fiddling with some of the parameters as suggested in other posts which concern similar (but not identical) issues to this. The first time I tried to run the app on the emulator after the update, I had many messages pop up in the event log, saying Android Studio Can't Bind to Local 86xx for debugger, whilst the Android Device Monitor was opened. Ever since then, with the ADM closed, I have had the problem described above, with no error messages showing in the error log.
Any help with this issue would be very much appreciated - please note it concerns the very latest version of Android Studio which I have only just had a popup requesting that I install. Build Tools Version in build.gradle has also been updated from 24.0.2 to 25.0.0.
If you haven't already done it:
Open Tools -> Android -> SDK Manager
Select tab SDK Tools, flag Android Emulator (version 27.0.5 at the moment) and Apply
This solution worked for me, hope this can help
I tried all of the aforementioned and it didn't help. What helped was disabling Instant Run in Settings -> Build, Execution, Deployment -> Instant Run.

Updating the Java SDK solved the problem for me.
you need to download the Android Emulator for Android Version 2.3 or make sure when you updated your AS from 2.2 to 2.3 all these components got updated and installed. I had the same problem and i just downloaded the Android emulator and it worked fine for me.
had the same problem, after two days of trying to solve this, i decided to uninstall android studio, and then install the new virsion 2.3 all over again, now Emulator working just fine!
*not much of programming, but it did the job!
Don't worry about updating anything. For some reason upgrading to 2.3 makes the default setting for running your app set to "androidDependencies" which does nothing except give you strange errors. Just go to Run -> Edit Configurations and in the window that pops up try to delete with the minus symbol the selection on the left pane with the task called android dependencies. Then click on "app" under the "Android App" expandable arrow at the top. (see the pic)
edit configuration window
I recently download Android Studio 2.3 and installed default components and some Android OS for emulator. When I use an emulator (version 26.0.0) I have problem with its sound and image (display is very poor).
I'm using Ubuntu 16.04.2, Kernel 4.8 and KVM is setup.
It's an example of my problem:
I think you've not enabled the developer settings in your emulator. Sometimes after update the emulator is reset and all the settings are lost. Enabling it, should solve the problem.
I'm using android studio about 2 weeks and everything is going right until I try to create a new app and the android studio ask me for updates to API level 22 and I did it. After this update my emulator doesn't load my app anymore, the emulator opens but the app doesn't show up and even appears at emulator.
Log:
Device Nexus_5_API_21_x86 [emulator-5554] is online, waiting for processes to start up..
I try to uninstall and install again the android studio but even reinstalling with API level 21 keep not working.
Even the default Hello World application doesn't load and not show up at my emulator.
I had the same issue, and was able to work around it by manually starting the emulator first, then running the app and choosing the running emulator
I had this same issue with my first app on android studio 2.1.2. I just tried to run it and see on emulator screen but app didn't show up there.
Remember to check the messages panel it saying something wrong with my java version. I had installed JDK 7. I installed JDK 8 and that fixed the problem.
It was working fine till I updated the Android SDK tools from the SDK Manager to version 24.1.2. However a virtual device was running at the time of the update and it asked me to close 3 processes in order for the update to continue. I thought the virtual device was interfering so I closed it and tried to proceed with the update,it gave me the same error. Therefore I cancelled the update and closed the studio. After restarting the studio,it gave an error saying the SDK could not be found and would not let me do anything else. I uninstalled the studio after deleting the SDK folder and reinstalled it. I downloaded the system images needed for the virtual devices and some other packages and created a new virtual device. When I tried to run the application,it gave me the dialogue box to chose the virtual device,I chose the newly created one and it gave the command to start the device. Yet no emulator window for the device appeared.
D:\sdk\tools\emulator.exe -netdelay none -netspeed full -avd MTK
emulator: device fd:5500
HAX is working and emulator runs in fast virt mode
HAXM is installed and it worked fine before. On checking the task manager upon launching the application,an emulator-x86.exe process appears briefly before disappearing. Nothing happens after that. Launching the program again gives the same result. If I try to launch the device from the AVD manager,I get the same result. I have tried using the arm images,varying the ram size,snapshot enabled/disabled,use HOST GPU enabled/disabled,system restarted,removal of /.android content,setting up the SDK in a different drive and deleting the ANDROID_SDK_HOME system variable and resetting it.
I have also tried with Genymotion. The virtual device window briefly appears and I can the see the android logo at startup but then it says "player.exe has encountered a problem and needs to close. We are sorry for the inconvenience." I have tried it using both the Genymotion Android SDK tools and the custom Android SDK tools to no avail. If I try to delete the device it says please stop the virtual device before deleting it even though it is not running.
I spent most of my day trying to solve exactly the same problem until one of my colleagues remembered he had exactly the same issue and that was related to Docker.
Docker uses Hypervisor Framework which is incompatible with the HAXM used by the Android emulator. Therefore if you try to run the Android emulator while Docker is running it will just quit without a warning. Quitting Docker will allow to use the simulator - Docker for Mac conflict with Android emulator
Sometimes it is because you are low on memory, or it might be an AVD specific glitch. I had many (20) devices saved in my AVD and was lower than normal on memory on my laptop. The native emulator folder would disappear right away but genymotion worked fine.
I removed the old devices and create a new one from scratch in AVD and the problem disappeared.
I am trying to run the Android emulator on a 64 bit Windows 7 machine. I have installed the Android SDK, JDK, Eclipse, and the Android plugins for Eclipse. From the SDK Manager, I have installed the Android SDK Tools, as well as all of the files for Android 4.1 (API 16).
From Eclipse, when I want to open the emulator I select the AVD Manager and click on a device that I have created. The AVD Manager says that the virtual device is a valid device. When I launch the machine, a box pops up that says "Starting Android Emulator," and there is a loading bar right below it. The bar will get to about 95%, and then the box will disappear and nothing will happen. There will be no errors and no messages in the console output box in Eclipse. I get similar behavior when I try to launch the emulator by running an app from Eclipse.
I have tried uninstalling and reinstalling the SDK to a new directory, as well as downloading a different version of Eclipse (I am currently using Eclipse Java EE, earlier I was using Eclipse Classic 4.2). I also tried downloading the API 15 platform and using that as a virtual device, and I still have the same issues.
I have checked my task manager, and the only new process that is ever created is adb.exe, and this only happens when I try to run my app, but not when I start the emulator on its own.
Any idea what might be causing this, or what methods I might use to troubleshoot this that will actually give me some kind of error message, rather than just disappearing and not doing anything? Thanks.
Edit: When I try to run the emulator from the AVD Manager directly, I get the same behavior as when running through Eclipse (loading box pops up, then disappears, then nothing).
Try to use BlueStacks emulator instead standart. It work much more faster and reliably. You can download it from http://bluestacks.com. After installing reboot the system. I think all be fine.
I had the same problem. Enabling Host GPU emulation worked for me.
