1->2->3 activities, at third "back button" I want to go to the first one

I have a MainActivity, then I call SecondActivity (where I choose a file whose data is given to ThirdActivity.

If back button is pushed, I want the app to go back yo MainActivity and not SecondActivity.

How can I do that?

You could also override onKeyPressed() (or whatever it's called) for the back button and startActivity().

There are two ways to do it.

  1. In SecondActivity, call finish() immediately after you start Activity 3.

  2. Pass in the NO_HISTORY flag in the Intent for SecondActivity when starting it in MainActivity.

Just after you call startActivity with the Intent for activity 3, call finish in activity 2:

//in activity 2

    Intent intent = new Intent(...);
    startActivity(intent);
    finish();
