Back key not fully killing app, notification persists
<p>Min SDK is 7</p>

<p>I have a little notification on the top of the screen, but when you press the back key on the main activity, it doesn't go away. What do I need to add to my back button override to fix this?</p>

<pre><code>@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
    if ((keyCode == KeyEvent.KEYCODE_BACK))
    {
        finish();
    }
    return super.onKeyDown(keyCode, event);
}
</code></pre>
