Android Question Viewing a single map from a OSM file, without downloading tiles

[Lakhtin_V]

In all examples by OSM, map is built from tiles, with access to the INTERNET. In my application, all work takes place on a predetermined section of the map. I want the application to work offline. I don't want to download tiles from the OCM server. I already have one file with the OCM extension, with a map of the area I need. How should I redo the code so that this map, a pre-downloaded map is displayed. I received the file with the OSM map on the main site of the mapsource project using export.
All examples use tile downloads and require certain registration and restrictions. Where can I find a primitive example of displaying a pre-downloaded single file? Is it possible in this case, after displaying, to add markers to it?

I tried this code but it doesn't work

        Dim mapAty As MapView
        ' Init MapView use lib [B]OSMDroid_3_0_8[/B]
        mapAtyrau.Initialize("map")
        Activity.AddView(mapAtyrau, 2%x, 30%y, 96%x, 59%y)
        
        ' Set Path OSM file
        Dim mapFile As String
        mapFile = File.Combine(File.DirInternal, "mapATY.osm")
        If File.Exists(File.DirInternal, "mapATY.osm") Then
            mapAtyrau.SetTileSource(mapFile)
        End If
