You missed import on native libraries, check https://github.com/nicolasgramlich/AndEngineExamples for details ;)

Thank you peter.But I've import all the required libraries. – Sümeyra May 28 '14 at 11:10
@peter_budo could you please elaborate a bit? I don't understand the problem and AndEngineExamples has no details on this problem. – Sudhanshu Nov 05 '14 at 00:17

The problem is your project is not linking the .so files.

Its very simple. Follow this simple steps

1) Create a new folder called "lib" inside the libs folder of the main app.

2) Copy all the folders ie.armabi , armabi-v7a etc from andEnginePhysicsBox2DExtension/libs folder, and paste in in the previously created "lib" folder in main app.

3) Now compress the "lib" folder as "lib.zip" and rename it to "lib.jar". this changes the zip extension to jar.

4) Finally add a line -- compile files('lib.jar') under dependencies{} in Build.gradle file of your main app.

5) Clean and build the project.
