Question

In my application i have two screen. Screen1 and screen2 . If i am in screen2 when i click the back button it shows the screen1. I need to close application at the time of clicking back button in the screen2 . How to do this???

Answer 1

Probably you start screen2 from screen1 via an Intent.

After you call startActivity(screen2) you should close screen1, via the finish() call.

Something like:

Intent screen2=new Intent(Screen1.this,Screen2.class);
startActivity(screen2);
finish();
