Set display orientation failed in android camera

I published a week ago an app named "Cam Shooter" which uses a camera surfaceview and a fire button.I got more than 20 reports about this error:

 java.lang.RuntimeException: set display orientation failed

In my code there is some lines to fix the rotation and aspect ratio of the camera, maybe it is causing the problem.

 @Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {       
    Parameters parameters = mCamera.getParameters();
    List<Camera.Size> previewSizes = parameters.getSupportedPreviewSizes();
    Camera.Size previewSize = previewSizes.get(4); //480h x 720w

    parameters.setPreviewSize(previewSize.width, previewSize.height);
    parameters.setFlashMode(Parameters.FLASH_MODE_AUTO);
    parameters.setFocusMode(Camera.Parameters.FOCUS_MODE_AUTO);

    mCamera.setParameters(parameters);

    Display display = ((WindowManager)getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
    if(display.getRotation() == Surface.ROTATION_0) {                        
        mCamera.setDisplayOrientation(90);                             // LINE 139
    } else if(display.getRotation() == Surface.ROTATION_270) {
        mCamera.setDisplayOrientation(180);
    }

    mCamera.startPreview();
}

Does anyone know how to get rid of this error ?

Have you found a solution to your issue? I'm wondering whether you've tried to stop capturing and drawing preview frames before setting new rotation of preview display? For example:

mCamera.stopPreview();                    
mCamera.setDisplayOrientation(degrees);
mCamera.startPreview();
