当我尝试将我在 xamarins 中的项目部署到我的 android 手机上时，会引发此错误消息。它适用于我朋友的手机，但不适用于我的。

【问题讨论】：

在您的手机上进入设置并找到所有已安装的应用程序。即使该应用程序可能不再在您的手机上显示为图标，它仍然可以安装。确保在应用管理屏幕中完全卸载了应用，然后重试
@GeraldVersluis 在应用中找不到它
@ChristianKhalil 你好，你朋友的设备是什么？如果使用 Android 10 物理设备，安装时需要继续点击接受对话窗口。

【解决方案1】：

按照以下步骤操作：

确保在调试配置中禁用快速部署
如果您运行的是 Android 6 或更高版本，请开启 Shared Runtime 以加快未来的部署速度
将 android 包名称重命名为 com.sample_company.sample_app 之类的名称（暂时，您可以稍后更改名称）
清理并重建解决方案

如果这不起作用，请在此处尝试此解决方案并滚动到 pinedax 答案：

Could not determine the installation package com.company.appName
