As file paths are not usable in API 29 and above for public files I suggest that you don't try to use them but use a Java FileDescriptor instead.

As per https://developer.android.com/training/data-storage#scoped-storage

And more specifically https://developer.android.com/training/data-storage/shared/media#open-file-descriptor

A lot of API's allow you to provide a FileDescriptor instead of a path.

e.g. Use https://developer.android.com/reference/android/media/MediaPlayer.html#setDataSource(java.io.FileDescriptor)

instead of

https://developer.android.com/reference/android/media/MediaPlayer.html#setDataSource(java.lang.String)

To get a fileDescriptor from a URI do the following (in Java)

ParcelFileDescriptor pfd =
                this.getContentResolver().
                        openFileDescriptor(URI, "r");

FileDescriptor fileDescriptor = pfd.getFileDescriptor();
