# FIXME: to make this work, this apparently needs:
# - a newer version of gradle in build.gradle (e.g. 3.2.1)
# - google() in the repos in build.gradle
# - gradle version 4.6 in gradle-wrapper.properties ?
# - some kind of flavor declaration?
# All while not breaking the existing Travis Android build.
# good luck.
