The problem is your project is not linking the .so files. 问题是您的项目未链接.so文件。
Its very simple. 非常简单。 Follow this simple steps 遵循以下简单步骤
1) Create a new folder called "lib" inside the libs folder of the main app . 1）在主应用程序的libs文件夹中创建一个名为“ lib”的新文件夹。
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 . 2）从andEnginePhysicsBox2DExtension / libs文件夹复制所有文件夹，例如.armabi，armabi-v7a等，然后粘贴到主应用程序中先前创建的“ lib”文件夹中。
3) Now compress the "lib" folder as "lib.zip" and rename it to "lib.jar" . 3）现在将“ lib”文件夹压缩为“ lib.zip” ，并将其重命名为“ lib.jar” 。 this changes the zip extension to jar . 这将zip扩展名更改为jar 。
4) Finally add a line -- compile files('lib.jar') under dependencies{} in Build.gradle file of your main app . 4）最后添加一行-在主应用程序的 Build.gradle文件中的dependencies {}下编译files（'lib.jar'） 。
5) Clean and build the project. 5）清理并构建项目。
