Since I have started finding a good third party libraries for game development on android platform, Im getting confused. So want to know from the people who are already using some of the game libraries themselves (no googled resources please).
So my question is : What are some of best Android Game libraries(2D/3D)?
Note: to keep this poll as useful as possible, please remember:
When adding a new library, provide a short summary of what it does / why you think it's useful. Please make sure the answers are not repeated.
One link/source per answer is preferable.
