When trying to create and start an Android 4.0 emulator I get the Android emulator skin but the OS doesn't seem to start.
I've installed the ARM EABI v7 package from Android SDK manager at tried to create an emulator, but got an error message about a missing userdata.img file.
I then found that the system $ANDROD_LIB$/system-images/android-14/armeabi-v7a/ library was created and copied these files into $ANDRROID_LIB$/platforms/android-14/images/ after which I could create a the emulator image.
When starting this new emulator this as stated above only shows the Skin (window) but don't start the OS. Im on a Mac, and all previously created emulators still work fine.
Installed rev 15 tools and with idea 110.291 I could choose armeabi-v76 start the emulator and restart it after 30 minutes and now it started.
