android thread still running after pressing back button

Question

I want to stop a thread when a back button is pressed.
I'm using Handler.

Answer 1

You need to use Handler's removeCallbacks() function.

Sample code:

@Override
public boolean onBackPress(int keyCode, KeyEvent event)  {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        handler.removeCallbacks(yourRunnable);
        return true;
    }

    return super.onKeyDown(keyCode, event);
}

Answer 2

You can't use either stop or destroy methods. In the onStop method you have to use this.
