# android create avd
# You can create an AVD for API level 10 (which 'ruboto setup' gives you by default) via:
# android -s create avd -f -n Android_2.3.3 -t android-10 --sdcard 64M --abi armeabi
android -s create avd -f -n Android_4.4.2 -t android-19 --sdcard 256M --abi x86 -t 1


#   Android 4.4.2 is a basic Android platform.
#   Do you wish to create a custom hardware profile [no]no
