AutoFocus for Android 4.0
<p>I have an camera app done for Android 2.3 which basically starts the CameraPreview class and draws a rectangle over the preview and does autofocus within the preview. It works without any issues in Nexus S running on Android 2.3.</p>

<p>But when I run this app on Galaxy Nexus running on Android 4.0 the autofocus functionality is not working.  I checked the developer website and the Camera.AutoFocusCallback is still available for Android 4.0.</p>

<p>Any idea what's the issue?</p>

<p>Thanks in Advance,
Perumal</p>
