android - Xamarin - “ManifestMerger”任务意外失败

问题描述

更新 Visual Studio 版本后，我的 Xamarin Forms 项目未构建，向我显示以下错误。我试图创建一个空白应用程序，但出现同样的错误。

错误：

========== Rebuild All: 1 succeeded, 1 failed, 0 skipped ==========

为了尝试正确，我尝试将 Xamarin.Forms 版本降级到 4.6.0.847 版本并在 AndroidManifest.xml 中添加工具，但不起作用。

环境：

适用于 Windows 的 Microsoft Visual Studio Community 2019 版本 16.10.3

Xamarin.Android SDK 11.3.0.4

Xamarin.Forms 5.0.0.2083

目标框架：Android 11.0 (R)

转载： https ://github.com/FlavineiOliveira/AppBlank

标签： androidvisual-studioxamarinxamarin.androidandroid-manifest

解决方案

现在问题解决了，但我不知道它发生了。

之前，我尝试过：

  1. 清洁和重建解决方案
  2. 删除文件夹 bin、obj 并重建解决方案
  3. 更新和降级 Xamarin.Forms 版本
  4. 关闭和打开解决方案以重建
  5. 重新启动我的电脑
  6. 修复 Visual Studio
  7. 卸载并安装 Visual Studio

现在，我只需打开解决方案并尝试重建。

成功。

环境是一样的。
