问题:

I want to implement an offline map of an area(city size), I need to use tiled map with several zoom levels and be able to zoom in/out by pinching on the map, double tap, pan and so on. I don't want to use OpenStreetmap. The map I use is a transit map, so it is very different from openstreetmap. I have tools to cut the map into tiles.

I wonder if there is any free library that I can use, I know this question has been asked(like android tiled map technique) but I could not find an acceptable answer.

I am aware of the mAppWidget, but it is too expensive. Would appreciate any help or hint.

There's a complete list of open-source map engines here. OSMand is one of the most popular. It'd be worth your time to get familiar with the Openstreetmap site; you can get your offline tiles from there as well.
