Is there a decent Android equivalent to Michael Hartl's Ruby on Rails Tutorial?
<p>I know about the <a href="http://developer.android.com/training/index.html" rel="nofollow">Android Official documentation</a> and some other resources, but these tend to be kind of boring for me. Is there anything like railstutorial.org for the Android world?</p>

<p>Suggestions much appreciated.</p>
