Question

How can I make it so that pressing the back button does not close my application? I want to display a confirmation message.

Thank you.

Answer 1

Source: Override back button to act like home button

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        //Display confirmation here, finish() activity.
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

That was a very quick search, try to look a little next time.
