<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>
|
|
|
|
<ul>
|
|
<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.
|
|
</li>
|
|
<li>
|
|
<a
|
|
href="src/com/example/android/touchexample/VersionedGestureDetector.html">VersionedGestureDetector.java</a>
|
|
is a version independent abstract class which factors out multitouch APIs that differ between platform versions. </li>
|
|
|
|
</ul>
|
|
|
|
