aSyncTask with CameraDemo and Preview gives looper error
<p>I am using the CamneraDemo sample as part of an Android project.   I have put the CameraDemo code inside an aSyncTask and from there it creates a new Preview.   The code for the Preview class creates a SurfaceView and since I moved the CameraDemo code into the aSyncTask I get the 'cant create handler inside thread that has not called looper.prepare()'  I have googeld around this and seen suggestions re using a runnable but can't get my head around how to do that with the aSyncTask situation. </p>
