    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
    Code:
    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 don't need to request any permission here. Watch the runtime permissions video tutorial.

    The problem is somewhere else.

    I thought so, but tried already all other ideas ...so..

    any leads where the problem could be ? the file is added with file manager, exists check is ok and then on load it crashes..

    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
