To solve this problem, we can’t find the solution of / storage / emulated / 0 / file. I can’t. You can try this

Open Device File Explorer-& GT; Locate the MNT folder -> Find the SDCard folder -> Find storage – & gt; Find your file in turn (add it if you don’t have one) -> Just put the full path in your code.
eg:

String sdpath = Environment.getExternalStorageDirectory()
                    .getAbsolutePath();
filepath = File.separator + "mnt" + File.separator + "sdcard" + sdpath + File.separator + "movie.mp4";
