Killing an app that fails the License check
<p>I've been implementing the Android market Licensing in my app and it looks like everything works.  At present, however, when the chec kfails, I'l displaying a Toast message and calling moveTaskToBack().</p>

<p>This is obviously not an acceptable way to close the app, since the user can simply open it again and carry on as before.</p>

<p>What would be the best way to actually kill the app after the Toast has displayed?</p>
