While developing AndEngine was a lot of fun, it also also consumed many(!) months of my life. It actually continues to cost me a significant amount of money to host the AndEngine forums.
If you made profit using your game and can afford to spare a fraction of it to the developer of the game engine you used, I would be very grateful! =)

- AndEngine has to be build with ADT-17 or higher!
 
- AndEngine relies on ADT to auto-generate a "BuildConfig" class. IntelliJ IDEA (as of 11.1.1) has not fully integrated with ADT-17+. In order to build AndEngine with IntelliJ IDEA, you can simply add the following class yourself in the root package (org.andengine):
 
package org.andengine;
public final class BuildConfig { 
    public final static boolean DEBUG = true;
