无法解析Google Glass上的符号“ CameraConfigurationUtils”

Question

I recently checked out some code from Git on Android Studio. The project uses barcodeScanner, I use CameraConfigurationManager.java but when I check I get an error from CameraConfigurationUtils. Might anyone know why? Thanks!

code:

 private CameraConfigurationManager() {
  }

  static void configure(Camera camera) {
    Camera.Parameters parameters = camera.getParameters();
    parameters.setPreviewSize(1280, 720);
    //parameters.setPreviewSize(1920, 1080);
    configureAdvanced(parameters);
    camera.setParameters(parameters);
    //logAllParameters(parameters);
  }

  private static void configureAdvanced(Camera.Parameters parameters) {
    CameraConfigurationUtils.setBestPreviewFPS(parameters);
    CameraConfigurationUtils.setBarcodeSceneMode(parameters);
    CameraConfigurationUtils.setVideoStabilization(parameters);
    CameraConfigurationUtils.setMetering(parameters);
    CameraConfigurationUtils.setZoom(parameters, ZOOM);
  }

  private static void logAllParameters(Camera.Parameters parameters) {
    if (Log.isLoggable(TAG, Log.INFO)) {
      for (String line : CameraConfigurationUtils.collectStats(parameters).split("\n")) {
        Log.i(TAG, line);
      }
    }
  }

}

You downloaded the zxing source code. The glass module depends on android-common which has the class you're looking for.
