如何在Android上使用opencv

@Override
 public void onResume()
 {
  super.onResume();
  if (!OpenCVLoader.initDebug()) {
   Log.d(TAG, "Internal OpenCV library not found. Using OpenCV Manager for initialization");
   OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_3_0_0, this, mLoaderCallback);
  } else {
   Log.d(TAG, "OpenCV library found inside package. Using it!");
   mLoaderCallback.onManagerConnected(LoaderCallbackInterface.SUCCESS);
  }
 }

private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
  @Override
  public void onManagerConnected(int status) {
   // TODO Auto-generated method stub
   switch (status){
    case BaseLoaderCallback.SUCCESS:
     Log.i(TAG, "成功加载");
     break;
    default:
     super.onManagerConnected(status);
     Log.i(TAG, "加载失败");
     break;
   }
  }
 };
