here is my code :

CvSVM svm= new CvSVM();
svm.train(trainData, sampleIdx);
String model= String.valueOf(svm);// i changed the svm object to string because save() accept only a string object
svm.save(model);

here is the error :

12-06 19:25:17.488 2712-2712/? E/cv::error(): OpenCV Error: Unspecified error (Could not open the file storage. Check the path and permissions) in CvStatModel::save, file /home/reports/ci/slave_desktop/50-SDK/opencv/modules/ml/src/inner_functions.cpp, line 71

**line 71 = svm.save(model);**

Actually looking at the error, I am suspecting it is not able to locate the saved SVM correctly. Could you check path and make sure you use absolute locations?
