#   1. Install an Android SDK from https://developer.android.com
#   2. Set the $ANDROID_HOME environment variable
#   3. Uncomment the line in WORKSPACE containing android_sdk_repository
#
# Note that if the environment is not set up as above android_integration_test
# will silently be ignored and will be shown as passing.
