Android: Go back to previous activity

Question

I want to do something simple on android app. How is it possible to go back to a previous activity.

What code do I need to go back to previous activity

Answer 1

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

This will get you to a previous activity keeping its stack and clearing all activities after it from the stack.

For example, if stack was A->B->C->D and you start B with this flag, stack will be A->B
