title: Android Google Maps API v2 not displaying anything
body: <p>I'm trying to work with Google Maps API v2, and I've read a lot of questions and answers and nothing so far. It works, never crashes, but it shows only a white display with Google maps logo in the bottom left corner and in the bottom right corner the 2 buttons for zoom out/in, and that's all. Why?</p>
