Restart Activity Android

Question

I'm working on an Android application that uses AndEngine. I try to restart an activity in this way:

private void restartActivity() {
    startActivity(new Intent(this, TMXTiledMapExample.class));
    finish();
}

This solution works on most devices, but I've realized that not the Nexus4.

In fact, I get the following error :
