Android Question How to make map in OSMdroid?

[Lyndon Bermoy]

I followed all the tutorials here: https://www.b4x.com/android/forum/threads/osmdroid-mapview-for-b4a-tutorial.16310/

But i can't make my own map using this OSMdroid. At first run I only see a gridlines in the MapView and its empty. I understand that it uses Mapnik and call other maps inside of it. But how can I put my own image map or something in the MapView?

I will be making a campus map navigator for our school and this library will be a great help for me to make this app for the school.

Thanks
