In part 2 of my tutorial (here is part 1) I’ll show you how to create offline maps using Mobile Atlas Creator and how to define min and max-zoom-levels in your app.
Mobile Atlas Creator is a cool open-source project, that allows you to use different map providers (OpenStreetMap, Google Maps, Bing Maps, Yahoo Maps, …), donwload these maps and export to different atlas formats. Have a look at their website (http://mobac.dnsalias.org/) and download the latest stable version.
