# Script to build all MediaPipe Android example apps.
#
# To build all apps and store them in out_dir, and install them:
# $ ./build_android_examples.sh -d out_dir
# Omitting -d and the associated directory saves all generated APKs in the
# current directory.
# $ ./build_android_examples.sh -d out_dir --nostrip
# Same as above except that the symnbols are not stripped.
#
# To install the apps already stored in out_dir (after building them with the
# usages above):
# $ ./build_android_examples.sh -d out_dir -i
# Omitting -d and the associated directory assumes the apps are in the
# current directory.
