Suppose I have an Android block of code that looks something like this:
String[] proj = {MediaStore.Audio.Media.ARTIST, MediaStore.Audio.Media._ID}; int[] to = n
MediaStore.MediaColumns.DATA is what you are looking for something like 'FILE_PATH'.
So file path can be retrieved by
String filePath = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA));
