Is there a way to combing the Mobile Map Package map data with an online map? I'm thinking this would serve two purposes:
1. To be a base map under labeled streets and other features.
2. Provide a fail back map in case there is no online connectivity - in other words, when the internet or a connection to our map server is unavailable at least we have the mmpk data to display.
In our application we currently use the Mobile Map Package (mmpk) data successfully similar to the example here:
Is there a way to add an online map to the MapView object as another layer or something else?
Yes, you can do this. As long as the online layer and the layers from the MMPK share the same spatial reference.
