您的元数据错误：main 是默认的本机库名称，如果未在清单中指定，请参阅 https://developer.android.com/reference/android/app/NativeActivity.html
或者您的派生 Activity 可能会忽略清单。 NativeActivity 不是为扩展而构建的，所以你应该格外小心。
我让它工作了。我注意到的问题似乎是我的项目特有的，我不知道为什么会这样。这是我发现的：
1) 由于某些原因，UEDeployAndroid.cs 中的 MakeApk 方法在清理过程中删除了文件。在清理期间，它还会删除项目的 build.xml。您可以在文件 UEDeployAndroid.cs 的第 1936 行中看到这一点。我不确定为什么清理会删除 build.xml。现在，由于 build.xml 被删除，Ant 不会构建项目。因此我不得不 运行 命令 'android update project'。我能够使用命令行构建工具继续构建过程。
2) 每次UE编辑器更新项目时，似乎都会创建一个新版本的原生库libUE4.so。因此当我 运行 GameActivity.java 时它没有找到库。我能够使用 dumpsys 找出文件夹路径和本机库版本。在重新安装之前删除旧包。
