Instead of loading your native library as

static{
    System.loadLibrary("YOUR_LIBRARY");
}

load your library after opencv manager is connected in "onManagerConnected" method in you "BaseLoaderCallBack". Following is my code snippet working for me

public void onManagerConnected(int status) {
                switch(status){
                case LoaderCallbackInterface.SUCCESS:
                    Toast.makeText(getApplicationContext(), "manager connected", Toast.LENGTH_LONG).show();
                    System.loadLibrary("MYNATIVELIB");
                    break;
                default:
                    super.onManagerConnected(status);
                    break;
                }
            }
