Answer 1

I don't know if this will work, but you could try it:

• From Activity A, start activity B for a result using startActivityForResult()

• In Activity B, when the user triggers Activity C, start activity C.

startActivity() returns immediately, so

• set a result that will inform A to finish as well,

• Call finish() in B.

• When A receives that result from B, A calls finish() on itself as well.

Failing that, you could make Activity C into its own app and then close the first app (with A & B) after it starts the second.
