Static Initialization on OpenCV Android

I'm trying to run `face detection' - Add OpenCV with static initialization using

http://docs.opencv.org/trunk/doc/tutorials/introduction/android_binary_package/dev_with_OCV_on_Android.html#application-development-with-static-initialization

But i get an "OpenCV error: Cannot load info library for OpenCV."

I did the following things:

  1. made native build manually. So the binary lib generated in libs->armeabi-v7a->libdetection_based_tracker.so

  2. added the code in FdActivity.java

if (!OpenCVLoader.initDebug()) { Log.e(TAG, "Cannot connect to OpenCV Manager"); }

code instead of

(!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_2, this, mOpenCVCallBack)) { Log.e(TAG, "Cannot connect to OpenCV Manager"); }

what seems to be the problem?

Static Initialization on OpenCV Android

Hi I am using OpenCV face-detection sample(OpenCV 2.4.2). I have changed the face-detection sample to OpenCV static initialization. I changed the below code in my FdActivity.java file. But I am not able to open native camera. when I call the "openCamera()" method it shows "Fatal error: can't open camera!" alert box. what seems to be the problem?

@Override

        requestWindowFeature(Window.FEATURE_NO_TITLE);

Static Initialization on OpenCV Android

Hi I am using OpenCV face-detection sample(OpenCV 2.4.2). I have changed the face-detection sample to OpenCV static initialization. I changed the below code in my FdActivity.java file. But I am not able to open native camera. when I call the "openCamera()" method it shows "Fatal error: can't open camera!" alert box. what seems to be the problem?

@Override
    public void onCreate(Bundle savedInstanceState) {
        Log.i(TAG, "onCreate");
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        Log.i(TAG, "Trying to load OpenCV library");
        if (!OpenCVLoader.initDebug()) {
            Log.e(TAG, "Cannot connect to OpenCV Manager");
        } else {
            mOpenCVCallBack.onManagerConnected(LoaderCallbackInterface.SUCCESS);
        }
    }

logcat:
