Question

我需要你的帮助。一段时间以来一直在为这个错误而苦苦挣扎。感谢您的帮助。

如果您需要更多信息，请告诉我。

我正在开发一款带有自定义 android 活动的游戏。因此，我创建了一个示例项目并更改了源代码以处理自定义 android 活动。我得到它来正确编译和构建应用程序，但是当我运行它时，我收到一条错误消息。日志猫有如下错误信息：

您的元数据错误：如果清单中未指定，ma​​in 是默认的本地库名称，请参阅https://developer.android.com/reference/android/app/NativeActivity.html

或者您的派生活动可能会忽略清单。 NativeActivity 不是为扩展而构建的，因此您应该格外小心。

Answer 2

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) 出于某种原因，UEDeployAndroid.cs 中的 MakeApk 方法会在清理过程中删除文件。在清理过程中，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来继续构建过程。

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。

谢谢
