Given the flexibility and power of this capability, the implementation of dynamic feature modules is relatively simple.

In basic terms, dynamic feature modules are built using split APK files which allow multiple APK files to be brought together to form a single app.

As we learned in “Creating, Testing and Uploading an Android App Bundle”, dynamic delivery and app bundles work by generating a custom APK file that contains only the bytecode and resources necessary to run the app on a specific device configuration.
