Opencv's Photo library method is giving error

I'm a complete beginner in opencv so please do excuse me if my question is foolish .Actually I was trying the following opencv function to reduce noise of an image but the function i.e Photo.fastNlMeansDenoising(mat,mat) is not working I don't understand why. As per the error it's showing that we can only use CV1,CV2 and CV3 which is there in my case but still I'm getting the error.

I also tried this answer but it couldn't solve my problem .

Can anyone please help me to fix this issue ?

Code:

Mat tmp = new Mat (bitmap.getWidth(), bitmap.getHeight(), CvType.CV_8UC3);

            Utils.bitmapToMat(bitmap, tmp);


            Photo.fastNlMeansDenoising(tmp,tmp);


            Utils.matToBitmap(tmp,bitmap);

Error:

 CvException [org.opencv.core.CvException: cv::Exception: /hdd2/buildbot/slaves/slave_ardbeg1/50-SDK/opencv/modules/photo/src/denoising.cpp:78: error: (-5) Unsupported image format! Only CV_8UC1, CV_8UC2 and CV_8UC3 are supported in function void cv::fastNlMeansDenoising(cv::InputArray, cv::OutputArray, float, int, int)

Try to update your library and your problem would be solved means if you're using 2.x then update it to opencv 3.0
