<p>This sample demonstrates how to design an application that is compatible across different Android versions. Applications
should degrade gracefully on older platform versions, dropping features or providing
when the platform support needed by features or functionality isn't available.</p>
<p>In this case, the CrossCompatibility application shows how to use APIs that are not available in all Android versions and
still create a single <code>.apk</code> that runs on all Android versions.</p>
<li>The main application's <a
href="AndroidManifest.html">AndroidManifest.xml</a> file declares that it is backwards compatible with API level 3 devices with attribute <code>minSdkVersion</code> in the <code>uses-sdk</code> tag.
is a version independent abstract class which factors out multitouch APIs that differ between platform versions. </li>

blogpost <a href="">here</a>.</p>
