| # 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 | ||
