Answer 1

Here you mCamera is returning null. This is due to improper initialization of camera. Use Camera.open(); to initialize it. Also check for any exceptions thrown in process of initialization. Also make sure that you have all necessary permissions in manifest file

 try {
    camera = Camera.open();
    Log.d(CameraCaptureActivity.LOG_TAG, "getCameraInstance()open:: " + camera);
} catch (Exception e) {
    // Check here for any exceptions
}
