Anki API. How to get file

AnkiDroid (Android) Help
1

Hello.
I am new to Android development.
I am trying to get sound file from anki droid api (for specific card).
I can get file name, I know where it is stored.
But I do not know how to load this file and play. (I do not know file uri).
Does anyone know how to get and play sound file, or at least how to compose uri for file stored in andkidroid?

I tried this:

        File file = new File("/storage//emulated/0/AnkiDroid/collection/google-9c5f81dc-c9c55395-1b3ef9a5-60c32e58-5c595fda.mp3");
        //Uri uri = FileProvider.getUriForFile(context, "com.ichi2.anki" + ".provider", file);
        //Uri uri = FileProvider.getUriForFile(context, "com.ichi2.anki" + ".flashcards", file);
        Uri uri = FileProvider.getUriForFile(context, "com.ichi2.anki" + ".apkgfileprovider", file);
        String myPackageName = context.getApplicationContext().getPackageName();
        context.getApplicationContext().grantUriPermission(myPackageName, uri, Intent.FLAG_GRANT_READ_URI_PERMISSION);
        Cursor fileCursor = mContext.getContentResolver().query(uri,null, null, null);
        if (fileCursor != null) {
            fileCursor.close();
        }

But it crashes with exception
