You can override the Back Button key press like so:

@Override
public boolean onKeyUp(int keyCode, KeyEvent msg) {

     switch(keyCode) {
     case(KeyEvent.KEYCODE_BACK):
          Intent a1_intent = new Intent(this, A1Activity.class);
          startActivity(a1_intent);
          finish();
          return true;



     }
     return false;
}
