Cool. I monetize most of my Android apps with ads. I found it hard to do this with games. I have not figured out game monetization yet. I guess in-app purchases are what a lot of people do. I ported an open source game to Android which is on over 40,000 devices currently. Normally that would mean over $100 a month in ads, but this app generates nothing. A lot of what I have been porting has been C++ (or C) code written in OpenGL 1.x, with lots of things like glBegin/glEnd statements etc. There are some bumps putting that on OpenGL ES but it has been OK so far. I know some game companies have a 90% common OpenGL ES C++ code base, and then the other 10% for iOS and Android specific hooks.
