Android Surface View Stops Updating

First off, my phone doesn't support the native camera, so I'm using the Sample1 as an example.

I have built an activity with some ProgressBars, some TextViews, and a surface view with the captured image. The Progess bars and TextViews update fine, but the SurfaceView will stop updating. It won't start again until I open another activity and go back to my activity.

I don't know where to look for the problem, so I'm looking for debugging tips, or requests for more information.

Android Surface View Stops Updating

First off, my phone doesn't support the native camera, so I'm using the 2.4.0 ~~equivalent of tutorial-0~~ tutorial-1(Add OpenCV) as an example.

I don't know where to look for the problem, so I'm looking for debugging tips, or requests for more information.

LogCat Info: In the beginning, things are working just fine. The surfaceView is created, normally. The frames are being processed. Then the surface gets created again, for some reason.

I/Sample1View.java( 2574): processFrame
I/Sample::SurfaceView( 2574): In While Loop (SampleViewBase::Run)
I/Sample::SurfaceView( 2574): surfaceCreated

Then there are some error messages from the camera?
