Answer 1

This error means that the library for physics box was not found. You have to add physicsbox2dextenstion.so file in app folder as shown in picture. You may be clear after watching picture. Hope this help you.

Answer 2

Project not able to find libandenginephysicsbox2dextension.so. Check do you have .so files inside your project. For different cpu architecture there are three .so file inside AndEnginePhysicsBox2DExtension.
