You can also add dynamic feature modules to your app project and include them in your app bundle, which allows your users to download those features on-demand. You can test downloading on-demand features through the Play Console testing tracks. However, you’ll need to join our beta program to publish app bundles that include dynamic features to production. Please express interest in joining the beta via the form below.
To publish an app bundle and participate in the beta, you must also enroll your app in app signing by Google Play in the Play Console.
