During the making of a game, we often get stuck. Fortunately, AndEngine has an active community that can help us resolve our problems. From a long-term view, it's also beneficial to give back to the community. One of the easiest ways is to give feedback on other developers' games. Creating a circle of friends in the community is always beneficial later on when you need to test your game with other people.
Tip
The community forums are located at http://www.andengine.org/forums/. There are also many sites with AndEngine tutorials. The best known is Mathew's tutorial website, which can be found at http://www.matim-dev.com/. You can also visit my website for more tutorials at http://android.kul.is/.
We can find more help in other game development communities that aren't directly associated with AndEngine. For example, http://www.stackoverflow.com is a good website for asking questions about programming.
