Map tiles disappear when after some time

Hello there,

I’ve developed an android application which track the current position, and draw routing paths, on a specific device, the map suddenly disappear. I checked the console, no errors found, I’m not sure what is the problem, anyone has an idea?

Thanks

Which map library do you use?

Better ask in their forum (Mapsforge / VTM is here) posting more details about the implementation.

I did exactly what is explained here

it works fine, but not on the device I want to run the app on.
