How can i implement offline map in android. I tried it with mapsforge library. It does not provides binary map file for Wisconsin state. So How can create my own map binary file ?

Thanks in advance.

You will need two things:

  1. a program that allows you to use the mapsforge library. Concerning this, you can stick with the program called AdvancedMapViewer which comes as an example with the library.

  2. a mapfile. Bascially you have to create your own mapfile from OpenStreetMap data. This is done with a plugin for Osmosis. This plugin is described here:

https://github.com/mapsforge/mapsforge/blob/master/docs/Getting-Started-Map-Writer.md

In short it works like this:

then put the created file wisconsin.map on your device and load it from AdvancedMapViewer.
