I have been working on Android for several months. Now I want to switch to games on Android. So, are there any resources, e-books or tutorials where I can study game development, be it 2D or 3D.
Thanks.
This is a long and difficult road. Start with 2D graphics by making some simple animations on your images, try making a simple game. Check out the API for 2D and 3D graphics.
Here are some useful links.
