Custom notify sound not working. Sound from internal storage, file owner not my app.

Code:

 Uri sound = Uri.parse(account.notifySound); 
 // "account.notifySound" contains path to audio file, obtained from ringtone picker 

 NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
 .setSmallIcon(R.drawable.ic_stat_new_message)
 .setContentTitle(messageTitle)
 .setContentText(messageBody)
 .setAutoCancel(true)
 .setSound(sound)
 .setContentIntent(pendingIntent);

 if (account.notifyLedColor > 0) notificationBuilder.setLights(MainActivity.ledColorsList[account.notifyLedColor - 1], 100, 50);

 NotificationManager notificationManager =
 (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
 notificationManager.notify(tag, 0, notificationBuilder.build());

Error:

java.lang.SecurityException: Permission Denial: reading com.android.fileexplorer.provider.FileExplorerFileProvider uri content://com.android.fileexplorer.myprovider/external_files/zedge/notification_sound/Marbles.mp3 from pid=1874, uid=1000 requires the provider be exported, or grantUriPermission()

How to fix it?

UPD:

I added after "Uri sound = Uri.parse(account.notifySound);":

 grantUriPermission("com.android.systemui", sound, Intent.FLAG_GRANT_READ_URI_PERMISSION); 

And got an error:

 java.lang.SecurityException: Uid 10204 does not have permission to uri 0 @ content://com.android.fileexplorer.myprovider/external_files/zedge/notification_sound/Marbles.mp3

UPD2:

Ringtone chooser opened multiple sound explorer, eg "Music", "Themes", again "Music" - another sound explorer, different on first "Music" ...

And when i select sound in "Music", picked soundUri = :

content://com.android.fileexplorer.myprovider/external_files/zedge/notification_sound/Snapchat_Tone-04a0409e-68c4-4294-beb3-bb137b8d5886.mp3

When select sound in "Themes" picked uri:

file:///storage/emulated/0/MIUI/.ringtone/Snapchat_Tone-04a0409e-68c4-4294-beb3-bb137b8d5886.mp3

This sound plays when it Uri begins with "file:///" (sound explorer "Themes") and got error when Uri begins "content://" (sound explorer "Music").

Although some other files play when choosing in "Music" with Uri begins "content://..."

As compiler said:

requires the provider be exported, or grantUriPermission()

You could try this:

grantUriPermission("com.android.systemui", sound,
 Intent.FLAG_GRANT_READ_URI_PERMISSION);

where sound is the Uri that you are using with setSound().

If you can not sure which packages should grant permission, below helper functional would loop search:

public static void grantUriPermission(Activity ctx, Intent intent, Uri uri, int permissionFlags) 
 List<ResolveInfo> resolvedIntentActivities = ctx.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);

 for (ResolveInfo resolvedIntentInfo : resolvedIntentActivities) 
 String packageName = resolvedIntentInfo.activityInfo.packageName;

 ctx.grantUriPermission(packageName, uri, permissionFlags);
