请帮助！
我已经尽力了，但是这个问题没有解决。
我已经检查了所有可以在Google上找到的问题，但仍然无法解决。
当我单击 Build 或 Build and Run 时，提示“无法合并android清单” 我正在尝试为android构建apk 。
这是控制台中列出的问题。
问题1。
Error: Error while saving blame file, build will continue
Error: The prefix "tools" for attribute "tools:ignore" associated with an
element type "activity" is not bound.

问题2。

UnityEditor.BuildPlayerWindow+BuildMethodException: 3 errors

我已经完成/尝试过的事情：（问题仍未解决）
通过Android Studio SKD管理器下载了所有sdk（API级别）10,11，一直下载到27。
我尝试过通过统一的玩家偏好来更改sdk，也尝试过更改manifist文件的SDK版本（我的当前说的是minsdk 15）。还尝试将AndroidManifest文件从temp / StagingArea复制到Assets / Plugins / Android，但仍然无法正常工作。
非常感谢您的帮助，
谢谢！
