I cannot start a virtual devices on android SDK when I press the start button on AVD manager, this error shows on my screen:
Starting emulator for AVD \'AVD
I just encountered this problem again and realized that newer versions of Android Studio and SDK are placing AVDs along the following path for OSX:
Users/yourUsername/Library/Android/sdk/.android/avd as opposed to the older practice of placing AVDs here: Users/yourUsername/.android/avd
So, I just updated my bash_profile file to point ANDROID_AVD_HOME to the new location--which did indeed contain the ini file for the AVD I'd created, and then the launch went fine.
