Short answer  try to create the same image using the old school  lt AndroidSDK gt  AVD Manager exe   Working in Android Studio  running all the integrated tools  it became natural to me not to use the old managers  AVD SDK    In my case  I had this problem when used the new  integrated  AVD Manager to create devices with old system images  API 11 and below  as I ve tested    When I tried to use the old school AVD Manager tool  located in  lt AndroidSDK gt  AVD Manager exe  to create these old device images  I had success

A common approach to follow to solve this problem   1 CHECK your SDK manager by running from your android studio and stand alons sdk folder by executing   android sh helps you to find broken packages   Try installing System emulator images with google API support than the Intel one  Just like   i solved my problem by running into another system image  Experment on KVM based Virtulaization suggested by Google for Linux

It is possible that you really have no system images  Double-check that  ANDROID HOME system-images android- lt YOUR DESIRED API gt  armeabi-v7a exists and is not empty  If they really are missing - install reinstall with SDK manager

Open Android studio  Go to setting   System Setting   Android SDK  Get the  Android SDK Location   Set the environment variable ANDROID SDK ROOT  to this value     It worked for me and I m on Windows 10 and Android studio 2 3 3

Normally  the error will occur due to an unsuitable AVD emulator for the type of app you are developing for  For example if you are developing an app for a wearable but you are trying to use a phone emulator to run it

I had the same error  The solution for me was change the ANDROID HOME path  First I took a look into tools- android- sdk manager from Android Studio  In that window  we can see the path where Android Studio looks for the SDK  image  Then I opened a Windows CMD shell  executed   echo  ANDROID HOME    but the path was different to the one in ANDROID STUDIO CONFIGURATION of the first step   The solution was to change in user environment  the ANDROID HOME  to the one of the first step  image  I finally closed the cmd shell  and opened another cmd shell to execute   echo  ANDROID HOME    the path was updated  and I could run my emulator perfectly

Just fixed this  Hope this helps others   Issue as in Android studio v2  This issue is for arm emulators  In this example I am using armeabi-v7a API 16  The fix is three steps   Step 1  Open sdk manager and make sure that you have installed ARM EABI v7a System Image  Step 2   This is the obvious case of adding the location of sdk to system variables   Right click on  This PC  icon on desktop  then  Properties - gt  Advanced system settings - gt  Environment Variables    Then add the path to sdk as new to system variables section using variable name ANDROID SDK ROOT   Step 3  Restart Android Studio for changes to register  After correcting the ANDROID SDK ROOT is undefined issue  the emulator still can t find the kernel files even though it can see that the sdk manager installed it to   path-to-sdk sdk system-images android-16 default armeabi-v7a kernel-qemu  The reason is a mix-up between the location the sdk manager installs the kernel file to and the location the emulator is looking for it   If you open your config ini  Android Studio -  AVD Mananger -   Show On Disk   for your emulator you will see the following line   image sysdir 1 add-ons addon-google apis-google-16 images armeabi-v7a    i e  path-to-sdk add-ons addon-       Instead of changing this value in the config ini file I copied   path-to-sdk sdk system-images android-16 default armeabi-v7a kernel-qemu    kernel file from the folder sdk manager installed   to   path-to-sdk add-ons addon-google apis-google-16 images armeabi-v7a   And that was the missing kernel file  You can run the emulator   You will need to close the Android Studio and reopen again  Give the emulator some time as it is 10x times slower compared to x86   Mine took about 5 minutes to start

In my case  Windows 10  the reason was that I dared to unzip the android sdk into non default folder  When I moved it to the default one c  Users  username  AppData Local Android Sdk and changed the paths in Android Studio and System Variables  it started to work

Hey there just ran into the same issue you did  the 3rd link down in google brought me to this bit of code that throws the error    if  kernelFile    NULL            kernelFile   avdInfo getKernelPath avd           if  kernelFile    NULL                derror   This AVD s configuration is missing a kernel file                   const char  sdkRootDir   getenv  ANDROID SDK ROOT                if  sdkRootDir                    derror   ANDROID SDK ROOT is defined   s  but cannot find kernel file in                             s  PATH SEP  system-images  PATH SEP                           sub directories   sdkRootDir  sdkRootDir                 else                   derror   ANDROID SDK ROOT is undefined                              exit 2     to which the person wrote       If the kernel image name ends in  -armv7   then change the cpu            type automatically  This is a poor man s approach to configuration            management  but should allow us to get past building ARMv7            system images with dex preopt pass   So I went back in and downloaded the x86 intel atom version for my desired API level and was able to get the emulator up without the error  Hope it helps you too

Go to Tools   Android   AVD Manager  Click the arrow under the Actions column on far right  where error message is   Choose Edit  Leave the default selection  For me  MNC x86 Android M   Click Next  Click Finish  It saves your AVD and error is now gone from last column   And emulator works fine now
