ok If this is the case then you can implement the "Back" key in your
code as:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
// your implementation
return true;
} else {
return super.onKeyDown(keyCode, event);
}
}
or if you are using API 8
@Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
}
