Updating old Android App to new versions and got a problem with mediaplayer

this is updated code supposed to play sound if the file exist
B4X:
Sub PlaySound(Zvuk As String, Opakovani As Boolean)
    Dim rp As RuntimePermissions
    rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)
    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
    If Result = False Then Return

    Dim cesta As String = rp.GetSafeDirDefaultExternal("shared")
       
    If File.Exists(cesta,Zvuk) = False Then
        LogColor("neeexistuje",Colors.Magenta)
    Else
        LogColor("Existuje",Colors.Magenta)
        mp.Load(cesta, Zvuk)
        mp.Looping = Opakovani
        mp.Play
    End If
End Sub

check for exists pass and then it crash on mp.load

You are using the file from the FILES Folder?

Yep the old version were downloading the files from somewhere but after update it stoped working so I tried to include sound files directly to the app. and yes those sound files are in Files folder now
