I wonder how this class work.
There isn't any constructor. I think it is here that we can modify the drawer, but I don't know how.
Class related to -> osmdroid-android
Lot of thanks, there isn't any specific documentation about this class.
Since osmdroid is a jar, we can't embed resources in it (at least that was the case when osmdroid was first developed). So the ResourceProxy is a solution to provide a "resource set" that is used throughout the app. You can create your own class from this and provide custom resources (like different languages, icons, etc...).
