使用存档管理器将解决方案发布到APK时，未安装APK。
当我使用ES文件资源管理器点击设备上的APK时，会显示一条消息：“应用未安装”
以下是我使用的版本：
Microsoft Visual Studio Premium 2012版本11.0.50727.1 RTMREL Microsoft .NET Framework版本4.6.01055
已安装版本：Premium
Visual C＃2012 04941-004-0043007-02064 Microsoft Visual C＃2012
Xamarin 4.2.2.6（27a9b40）启用Visual Studio扩展 开发Xamarin.iOS和Xamarin.Android。
Xamarin.Android 7.0.2.42（501e63c）启用Visual Studio扩展 开发Xamarin.Android。
Xamarin.iOS 10.3.1.7（8b53676）启用Visual Studio扩展 Xamarin.iOS的开发。
有没有人可以确切地了解为什么没有安装该应用程序？
当我使用设备记录时，我看到以下输出

问题在于我忽略了使用分发功能对APK进行签名。一旦我能够使用我的密钥签名，APK就会成功安装。

为其他人澄清......
您必须做三件事来构建APK并在设备上运行它。
