ANDROID_EMULATOR_HOME
Sets the path to the user-specific emulator configuration directory.
default location of the emulator configuration directory is $ANDROID_PREFS_ROOT/.android/.
ANDROID_AVD_HOME
Sets the path to the directory that contains all AVD-specific files, which mostly consist of very large disk images. The default location is $ANDROID_EMULATOR_HOME/avd/. You might want to specify a new location if the default location is low on disk space.
