Basically, what I want to do is something like this: enter image description here
I read some solutions about using another maps, but I have all my project build it on Google Maps, so I was looking for something to adapt it to that.
I want to download an area of the map (as map or as image) with markers that are in a local database, and after load it offline with their respective markers.
I hope someone can help me, is the last part of my project.
Thank you so much.
