卸载和重新安装 APK 后 Xamarin 表单“未安装应用程序”错误

[英]Xamarin Forms “App Not Installed” Error After Uninstall & Reinstall of APK

原文 2018-07-13 13:56:58 1 2 c#/ visual-studio/ xamarin/ xamarin.forms/ xamarin.android

I have built an APK of an Android app which I created with Xamarin Forms.我已经构建了一个使用 Xamarin Forms 创建的 Android 应用程序的 APK。 The APK works perfectly, but if I uninstall it and reinstall it, I get an error message "App Not Installed" upon trying to reinstall the APK. APK 运行良好，但如果我卸载它并重新安装它，我在尝试重新安装 APK 时收到错误消息“未安装应用程序”。

If I change the version number / version name and make a new APK, it can be reinstalled again successfully, but this means users can't simply uninstall / reinstall the same version of the app at will.如果我更改版本号/版本名称并制作新的APK，它可以再次成功重新安装，但这意味着用户不能随意卸载/重新安装相同版本的应用程序。 How can I make it so it's possible to uninstall / reinstall the same APK successfully?我如何才能成功卸载/重新安装同一个 APK？ Thank you.谢谢你。

I had the same problem, and I found the solution here .我遇到了同样的问题，我在这里找到了解决方案。 Basically, Play Protect will not enable you to reinstall, even if it prompts you again.基本上，Play Protect 不会让您重新安装，即使它再次提示您。 Disabling Play Protect solved it for me.禁用 Play Protect 为我解决了这个问题。

The solution from here worked for me: 这里的解决方案对我有用：
