I added code to pick Camera using CameraInfo because just adding Camera.open() was not working on HTC devices and I changed the holder in mCamera.setPreviewDisplay(holder) to mHolder which is an instance variable.
I try to open the custom Camera in the onResume of an Activity,in the logcat output I have noticed that the code goes into surfaceChanged after surfaceCreated because that is where I set the Camera Preview size using Parameters,then it seems to have failed to allocate memory: GenericAlloc: Failed to allocate device memory(I have low memory on my device ~2.47GB free space)mis it because of that.
I get the following huge,unknown error,you can take a look at my CameraActivity and my CameraPreview:

Now it looks like nothing can connect to the Camera,not even the default Camera app.Why did the error occur and how can I resolve it?
EDIT:
This seems to be a freak occurance,I switched the phone off and turned it back on again and it seems to be working just fine.Another cause could be calling this code in surfaceDestroyed:
private void killCamera()
{
if(mCamera!=null)
{
mCamera.cancelAutoFocus();
mCamera.release();
mCamera=null;
}
}
