Emulator in Android Studio doesn t start

Question

I think it s a problem with the SDK reference in Project Structure  but when I click run and I choose Launch Emulator nothing appears

User · Answer

For me  on MacOS X  the emulator process was already running  but without the interface  I had to open MacOS Activity Monitor and kill the process qemu-system-x86 64  Afterwards  running the app launched the emulator successfully  Select the process called qemu-system-x86 64 in Activity Monitor and click the X button to kill the process  Then click Run or Debug in Android Studio

I had the same issue in Android Studio 2 3 3 on Mac OS X 10 12 6 and the issue was caused by Android Studio using an old version of HAXM  6 0 3 when it should have been 6 2 1      kextstat   grep intel   148    0 0xffffff7f8342c000 0x14000    0x14000    com intel kext intelhaxm  6 0 3  50449AFC-F7C6-38A0-B820-233E8A050FD6  lt 7 5 4 3 1 gt    Removing and reintalling HAXM from within Android Studio according to the instructions didn t work  https   software intel com en-us android articles installation-instructions-for-intel-hardware-accelerated-execution-manager-mac-os-x  Instead  download the HAXM installer manually or if that link expires  find it under https   software intel com en-us android tools under Intel   Hardware Accelerated Execution Manager  Intel   HAXM    After running the installer  it now shows that the current version of HAXM is installed     kextstat   grep intel   169    0 0xffffff7f83472000 0x1d000    0x1d000    com intel kext intelhaxm  6 2 1  7B6ABC56-699C-3449-A0EC-BEB36C154E3C  lt 7 5 4 3 1 gt    After upgrading HAXM manually  I m able to launch x86 64 emulators     Old answer  which might work instead  note that this didn t work for me for x86 64 images    Create a new device   Tools- gt Android- gt AVD Manager    Create Virtual Device  Tablet -  Nexus 7 -  Next  The Recommended tab should be highlighted   Even though I had the API Level 25 SDK installed  it showed   Nougat Download 25 x86 Android 7 1 1  Google APIs   So I clicked Download link which seems to have repaired the API Level 25 SDK   I finished creating my new device and it ran fine   Unfortunately I had already deleted my old device  so if this works for someone else  please leave a comment here to let us know if your original device worked afterwards  thanks

I had the same problem  but now I m using it successfully   As you know  the minimum RAM required to run android studio is 4 GB  but if you only have 4 GB RAM  you probably won t be able to run many other applications at the same time   It s also possible that some windows driver  e g  graphics  is incompatible  You may want to experiment with software and hardware options for graphics   https   developer android com studio run emulator-acceleration html  It might also help to increase the connection timeout in settings tasks

I had a similar problem    Android Emulator doesn t open  You need to discover the reason of this    You could run your emulator from the command line  For this you could copy and paste your command line from  Run  or  AVD  Android Studio console   For example        path  android-sdk tools emulator exe -avd Default Nexus 5 -netspeed   full -netdelay none    When you launch it from a command line terminal  It give you a message with the error  In my case it was useful for discover the problem         android-sdk tools emulator  ERROR  x86 emulation   currently requires hardware acceleration  Please ensure Intel HAXM is   properly installed and usable  CPU acceleration status  HAX kernel   module is not installed     I needed to activate GPU acceleration with a tool to enable it on my machine  I solved it installing from SDK Manager the tool HAXM    I had another problem    For example i had assigned a bad url for skin path of my virtual device     To solve it I have configured my virtual device with a valid skin from my platform sdk    path  android-sdk platforms android- number  skins SCREEN SIZE     Now it is opening fine   Update 8 8 2019   For newer version of Android SDK  emulator path should be     path  android-sdk emulator emulator exe   reference  thank you  CoolMind

I had the same problem on Windows 10  after I moved my android-SDK folder to D   as I was low on space on c     It turned out that the Android emulator looks for Android SDK via Global  environment  Variables  not the path defined inside Android Studio   So I edited the Environment variable of ANDROID HOME and that was it

User · Answer

If anyone is still having trouble with launching the avm take note of the android studio event log when you try to run the avm  When I tried running the avm android studio mentioned that my environment variable ANDROID SDK HOME was set to the same place as ANDROID HOME and it shouldn t be  It recommends deleting the variable ANDROID SDK HOME which I did and then restarted android studio and avm started working

User · Answer

Although some answers above suggest to increase the RAM of the AVD but this does not help me  The AVD seems to load forever  but at the end it does not go online  In Android Studio 3 3 2 I was able to get my AVD to start and run by changing Graphics in the Emulated Performance section from Automatic to Hardware-GLES 2 0

User · Answer

It seems that  Waiting for target device to come online      is a generic message that appears  always  when the emulator can not start properly  And what s the cause of that  As you can see  there could be many causes   I think the best way to find the concrete error with the emulator is to start it within a terminal  So   1 - Open a terminal and go to this folder   Android Sdk tools  2 - Start the emulator with this command     emulator -avd EMULATOR NAME -netspeed full -netdelay none   You can see the name of your  previously created with AVD Manager  emulators with this command     emulator -list-avds   If everything is ok  the program doesn t start  and it writes in the terminal the concrete error   In my case  the application says that there is a problem loading the graphic driver   libGL error  unable to load driver  r600 dri so    As it is explained here  it seems that Google packaged with Android Studio an old version of one library  and the emulator fails when it tries to use my graphic card   Solution  Very easy  to use the system libraries instead of the packaged in Android Studio  How  Adding  -use-system-libs  at the end of the command  So     emulator -avd EMULATOR NAME -netspeed full -netdelay none -use-system-libs   The definitive solution is to set the ANDROID EMULATOR USE SYSTEM LIBS environment variable to 1 for your user system  With this change  when I run the emulator within Android Studio  it will also load the system libraries   PS 1 - The easiest way I found to set the environment variable  it s to modify the script that launch the Android Studio  studio sh  in my case it is inside  opt android-stuido bin   and add at the begining this   export ANDROID EMULATOR USE SYSTEM LIBS 1   PS 2 - I work with Debian Jessie and Android Studio 2 2 3  My graphic card is an ATI Radeon HD 6850 by Sapphire   UPDATE December 2017  I had the same problem with Debian Stretch and Android Studio 3 0 1  same graphic card   The same solution works for me

now I use android studio on mac  I have the problem  When I executed emulator in cmdline  I got error message  So I thought that there maybe not was the exe permission on emulator  Then when I added the permission on it by chmod  everything work

User · Answer

I spent several hours on this problem  What worked for me was opening the Tools- Android- SDK Manager  choosing Android SDK under System Settings on the left of the screen and going to the SDK tools tab  I then unchecked the settings for Android emulator and the Intel x86 Emulator Accelerator  I applied these changes  restarted Android Studio and then re-checked these option and applied the changes  The program reinstalled the emulator components and things seem to work  Hope this helps someone

User · Answer

I ve faced similar problem  You can edit the configuration or create new AVD with higher RAM  Also try increasing Heap to 128  Emulator will work smoothly even without HAXM

User · Answer

Besides using an external emulator such as bluestacks  you can also create a new new AVD and choose a system image with an ABI of armeabi-v7a with an API level of 21  instead of choosing ABI of x86 which fails  I was having the same problem  i tried this and it worked  hope this will be useful as well

User · Answer

One reason could be that the chosen ABI does not fit to your system  For me  only arm64 is working

User · Answer

It probably won t start because you    no CPU is installed  then follow this answer  Unable to create Android AVD because of Target and CPU ABI settings     OR   don t have the correct SDK downloaded    If you migrated your project from Eclipse chances are that on running an emulator you will get stuck with this message not seeing anything else   Waiting for device   If you open the device manager you probably see something like this     Just recreate your devices

User · Answer

Just check the error log it is necessory that yoou should know the fault  It may be window acceleration HAXM error as mentioned above you have to install it separately in that case    generally the path is   c  users youruser appdata local run some bat file named like HAXM   here the error pops in android studio is and above was the solution to this     android-sdk tools emulator  ERROR  x86 emulation currently requires hardware acceleration  Please ensure Intel HAXM is properly installed and usable  CPU acceleration status  HAX kernel module is not installed   tell me further if the issue persists altough after this i suppose you will be able to see nexus 5 emulator on screen

I have similar problem but I have solved it by switching to  Android 4 2 2 armeabi-v7a   I needed to test it on Jelly Bean  in my AVD and it fixed the problem for me   What seems to happen is that my processor is AMD and Intel X86 hardware emulation couldn t start  So I changed to use  API  other than  x86   even though it recommended me to use x86   Hope this helps

I faced the same problem  From some research that I did  I realized that my computer does not support virtualization  So I had to install BLUESTACKS  Believe me it worked   you can also try it    Just go to your directory C  Android sdk platform-tools  and double click adb Ensure that your bluestack is running  When you try to run the project  it automatically shows up to run with the bluestacks    just choose the bluestack and you are done    If you want the setup of bluestack  just google it you can have a number of sites to download from for free
