原样stated here by 42labs :

Luckily it is very easy to fix - in your sources root (the directory where AndroidManifest.xml is) make a directory named libs inside which then make a directory named armeabi. Now get AndEnginesources (from an OpenGL ES 2.0 branch) - from here. You can clone the repository or download it. Doesn’t matter.

What matters is that you should copy the libandengine.so available there in libs/armeabi to the libs/armeabi you have just created in your directory. Will fix the issue :)

Probably this is not the official solution, maybe we haven’t seen a note somewhere on AndEngine’s forums, but this method fixes the problem in 30 seconds and doesn’t produce any other issues.

And - Why did it crash? What does it fix?

It’s quite funny actually. Google developers, when preparing the Froyo Java SDK, forgot to implement Java versions of some of (standard!) OpenGL ES 2.0 functions. The solution to this problem is to use JNI to create a call bridge to a native function that is missing in the SDK. AndEngine has this bridge in the mentioned libandengine.so. When the engine is launched it checks the version of OS. If it is Froyo (or lower) it tries to load the library. If the library is not present it has no way of solving this and has to crash.
