Android book for custom ROM building
<p>I'm looking for a book or other resource which gives me a good overview over the Android system.<br>
Things I'm looking for:</p>

<ul>
<li>how to define preinstalled apps / widgets</li>
<li>how to add drivers for sensor data (e.g. accelerometer)</li>
<li>how to configure display parameters</li>
</ul>

<p>Every recommendation is welcome as I didn't find anything yet.</p>
