Application can't be moved to SD card
<p>I have put the following in <code>AndroidManifest.xml</code> as described in the <a href="http://developer.android.com/guide/appendix/install-location.html" rel="nofollow">article</a>:</p>

<pre><code>&lt;application android:name="MyApp" ... android:installLocation="auto"&gt;
    ...
&lt;/application&gt;

&lt;uses-sdk android:minSdkVersion="4" android:targetSdkVersion="8" /&gt;
</code></pre>

<p>but the <code>Move to SD card</code> is remaining disabled for my application (other installed applications on my phone can be successfully moved to SD card). What's wrong with it?</p>
