Can multiple Android applications share a single process and application context?

Question

I am wondering if I could share a singleton on the application context across multiple applications? Each application would be in its own APK but This might sound like bad

Answer 1

Yes, they can. You just need to assign same values to android:sharedUserId and android:process in both applications and sign them with same certificate.
