I need to finish my thesis. I want to make like an GIS on my android. All I need is build android application that can show the map, draw polygon overlay on it, add house button in it, and save as an image. I'd already know how to show Google-Maps on my android, but I don't know how to draw polygon overlay on it. All I need seems like this screenshot.
