al_get_native_file_dialog_path - Allegro 5 API

       Returns  one  of  the  selected paths with index i.  The index should range from 0 to the return value of
       al_get_native_file_dialog_count(3alleg5) -1.

              Note: On Android, this function returns a content:// Universal Resource Identifier  instead  of  a
              file  path  due  to  the  constraints  of  Scoped  Storage.   Selected files may be accessed using
              al_android_open_fd(3alleg5).
