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

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

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

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

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

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

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

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
