PhysicsWorld的AndEngine错误

Question

我是java和andengine的新手，并尝试制作已发布的跳线游戏以了解它是如何工作的。一切都很好，但如果我尝试加载PhysicsWorld，我会得到以下错误：

也许有人可以帮助我哪里错了？我怎么说，我是这个系统的新人xD

Answer 1

此错误表示未找到物理库框。您必须在app文件夹中添加physicsbox2dextenstion.so文件，如图所示。看完照片后你可能会很清楚。希望这对你有帮助。

Answer 2

项目无法找到libandenginephysicsbox2dextension.so。检查项目中是否有.so个文件。对于不同的cpu架构，AndEnginePhysicsBox2DExtension内有三个.so文件。
