Android LunarLander example does not seem to use 'invalidate'
<p>I am studying the LunarLander example in the Android sample code: <a href="http://developer.android.com/resources/samples/LunarLander/index.html" rel="nofollow">http://developer.android.com/resources/samples/LunarLander/index.html</a></p>

<p>I am puzzled because the comments say in several places that the code uses 'invalidate' to trigger redrawing. But I can't find it in the code.</p>

<p>More importantly I believe that drawing should always happen in a View's onDraw and not inline elsewhere in a thread. </p>

<p>Has anyone studied that example and have comments about why invalidate() is not being called?</p>

<p>Thanks for sharing your insights!</p>
