Unity3d 无法在编译时合并多个 android 清单

Question

我最近开始了一个项目，并尝试从 Firebase 添加一些包。问题是当我尝试构建一个 android export unity 时无法合并项目中包含的 android manifest 文件。 （我不确定，但似乎当我解决冲突时它不起作用，因为在每次构建期间统一删除清单文件并重建具有相同冲突问题的清单，但也许我没有很好地处理冲突）。

这是错误：

您可以尝试使用 Gradle 系统。如果仍然无法正常工作，请将您的项目导出到 Android Studio。它会让你更好地理解问题。然后，您可以直接从 Android Studio 解决这些错误。

确保您已从 Assets > Play Service Resolver > Android > Force Resolve 导入所需的库。
