ExoPlayer error 2101 - File not found

[Saezy (Farhad Stanekzay)]

I have tried this and that error stops:

Problem with picking audio file

The TaifunPlayer needs a full path to access the removable SDcard, e.g .: file:///storage/9C33-6BBD/Music/Pink Floyd - Wish You Were Here.mp3 Only an absolute path is required for access to the ASD and the other external storage, e.g.: /storage/emulated/0/Music/loop.ogg But the full path works as well. So use always a full path. [grafik] For more details, see also here.

But now I get this error: java.io.FileNotFoundException

Edit: This was solved by changing exoplayer to Taifun player, thank you @bodymindpower for the solution linked here!
