                    filemanagerstring = selectedImageUri.getPath();

                    //MEDIA GALLERY
                    selectedImagePath = getPath(selectedImageUri);

                    //DEBUG PURPOSE - you can delete this if you want
                    if(selectedImagePath!=null)
                        System.out.println(selectedImagePath);
                    else System.out.println("selectedImagePath is null");
