thank you for this great help but unfortunately this isn't my case. not me who created the cursor and iterate through it. I am just receiving the Uri from another activity via an intent. and it isn't good to iterate through all images to find one its Uri matches one I received especially that I am not sure it will always be a Uri of an image.
still can I get the file name?
