Android equivalent of IOS App-Groups functionality

Question

Is there anything equivalent of ios app groups for interprocess communication and sharing data?

I know android has Content Provider, but that is not the same thing.

Ios app groups:

App groups allow multiple apps produced by a single development team to access shared containers and communicate using interprocess communication (IPC). Apps may belong to one or more app groups.

Android content provider:

Content providers are Android’s central mechanism that enables you to access data of other applications – mostly information stored in databases or flat files. As such content providers are one of Android’s central component types to support the modular approach common to Android. Without content providers accessing data of other apps would be a mess.

Answer 1

You can communicate via IPC over BroadcastReceivers and via ContentProviders. If you want to share files, any apps signed with the same key can access each other's files. Broadcasts and ContentProviders can be tied to permissions to keep other apps out
