About bundletool

bundletool is the underlying tool that Gradle, Android Studio, and Google Play use to build an Android App Bundle or convert an app bundle into the various APKs that are deployed to devices. bundletool is also available to you as a command line tool, so you can recreate, inspect, and verify Google Play’s server-side build of your app’s APKs.

The motivation of this plugin is to extract an universal .apk file from an .aab file. Since we cannot distribute aab files, it's great that we can extract from the very same binary a file that we can distribute internally.

Usage

In your Fastfile you need to use bundletool action. After you build the .aab file you can run the following code.

bundletool(
  ks_path: keystore_path,
  ks_password: keystore_password,
  ks_key_alias: keystore_alias,
  ks_key_alias_password: keystore_alias_password,
  bundletool_version: '1.10.0', # For searching a specific version of bundletool visit https://github.com/google/bundletool/releases
  aab_path: aab_path,
  apk_output_path: apk_output_path,
  verbose: true,
  cache_path: cache_path
)

This will output the universal .apk in the output path you set.
