I have a problem while running the examples from andengine. The error I\'m getting is at this line:
System.loadLibrary( \"andenginephysicsbox2dextension\" );
The error you are getting is because you have to build the Box2D extension yourself. I think there is tutorial how to do it. However i stoped there and downloaded the demos from market. Then eventually switched to libGDX.
looks like you missed to copy the native libraries. AndEngine is now hosted on github and it is in perfectly active development! ( https://github.com/nicolasgramlich/AndEngine ) more info on what changed in the new GLES2 version here: http://www.andengine.org/forums/announces/andengine-gles2-pre-release-on-december-23rd-t6097.html#p26851
Using AndEngine as a library project is recommended and this will automatically 'copy' the native libraries to your project.

The new way of using andEngine is to include the git repos as libraries (without making any jars)
