Answer 1

I faced same issue, i fixed it by - Adding mCamera = null; in surfaceDestroyed(SurfaceHolder holder) method of Preview class.

public void surfaceDestroyed(SurfaceHolder holder) {
    // Surface will be destroyed when we return, so stop the preview.
    if (mCamera != null) {
        mCamera.stopPreview();
        mCamera.release();
        mCamera = null;
    }
}

and - Adding

camera = Camera.open();
    camera.startPreview();
    params = camera.getParameters();
    preview.setCamera(camera);

in OnResume() method of my CameraActivity.
