Describe the problem

• In Setup -> Step 2 -> Manual setup, the explanation to proceed manually in order to support both SplitCompat and PlayStoreDynamicFeatureManager is missing in all cases the exact path/file where to add the mentioned java/kotlin code.
• Furthermore, code fragments are Java, when actually most of Android modern code is based on Kotlin. At least both Java and Kotlin code should be provided.

Expected fix

Refactor the mentioned step to provide exact file paths to edit, and provide Java and Kotlin code for all code fragments.

@domesticmouse, you're up this week. Any chance of helping with this?

[domesticmouse]

Two problems. First, I don't know kotlin. Second, I'm fully focused on I/O.

@RedBrogdon can you pick another DRE to own this issue?
