I am going to implement an in-application maps in my Android application, so my first thought was: Google Maps.
However it does not support caching - if user closes application, all loaded maps are deleted. Then I found Bing Maps which supports caching.
There is Bing Maps Android SDK, but it is delivered as a whole Android application. I do not know at all how to use it.
Are there any tutorials, examples, etc showing how to use it with custom application as a build-in activity ?
