B4XMap (Open Street Map viewer)
Just came across this and thinking about moving to this from OSMDroid. Trying to figure out how to download a map area based on min and max latitude and longitude and can't figure out how to get from latitude and longitude to the Open Street Map x and y tile numbers, so I can do something like...
I use the nice OSM Viewer b4xmap and I have just one single question.
How do I find out if a specific position (lat/lon) is already visible on the map or not.
If Not I would like to show that position If it is already visible then no repositioning required.
Thanks for your kind support
