Libgdx游戏在Android上崩溃

Question

我使用libgdx做了一个游戏，它之前在桌面和android上运行良好。 我不确定它是否因为我开始使用box2d物理引擎和liquidfun粒子，基本上发生的是，当我点击我的游戏时它开始加载然后加载它应该去游戏屏幕，但它崩溃然后说“不幸的是，myGame已经停止了“。

错误信息：

E/AndroidRuntime: FATAL EXCEPTION: GLThread 3764
Process: com.nivekbryan.puffypuff, PID: 8416
java.lang.NoClassDefFoundError: Failed resolution of: Lcom/badlogic/gdx/physics/box2d/World;

我按照这个设置教程介绍了如何移植liquidfun库，它从2014年开始有点老了。 游戏运行Ok作为桌面应用程序。

这是我的build.gradle文件（依赖项），可能是什么问题？ 为什么作为桌面应用程序而不是作为Android应用程序？

更新：

我发现这个解决方案链接所以我做的是将gdx-liquidfun.jar复制到Android - > libs然后右键单击并添加为库，但我仍然得到错误。 请帮助，提前谢谢（我正在使用Intellij社区版）

把它放在android依赖项中：

    natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-armeabi"
    natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-armeabi-v7a"
    natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-x86"

这在核心依赖项中：

    compile "com.badlogicgames.gdx:gdx-box2d:$gdxVersion"
