Using a Pre-Downloaded Offline Map

Question

I want to download a map for offline use, save the map files in my code, and then display that map if no Internet connection is established on application startup. Is this possible, or is it only possible to use an offline map that you have already saved earlier in the same session? If it is possible, how would I do this?

By downloading map data before your trip, you can access routes, landmarks, and important locations without relying on mobile data or Wi-Fi. Offline maps are especially useful for traveling in remote areas, hiking, road trips, or click here places with poor network coverage.

Thanks for your response, Guillaume. I've spent the last month trying to get a trial of ArcGIS Pro so that I can create mobile map packages, but customer service has told me that I can't do that while I have an active ArcGIS developer license. Is there a way that I can create mobile map packages without ArcGIS Pro? It seems like there should be a way, right?

Hi,

if you have an Internet connection upon application startup, then lose it later

This sample shows how to generate an offline map, this step requires to be online to get the data. But when you have an offline map (the mmpk file in sample), you can use it offline.

Here's a sample to open a mmpk file: https://developers.arcgis.com/qt/cpp/sample-code/open-mobile-map-map-package/
