我无法从Visual Studio 2015 / Xamarin将hello world应用程序部署到我的Android设备（Oneplus 3）。
我在MainActivity中检查了装饰器，MainLauncher设置为true。
我检查了Build-＆gt; Configuration Manager中的Deploy选项，并勾选了它。
我尝试从手机上的应用程序管理器中卸载应用程序，但它没有列出。
我尝试使用adb卸载应用程序但是它返回了此错误：
java.lang.IllegalArgumentException: Unknown package: com.test.helloandroid
at com.android.server.pm.Settings.isOrphaned(Settings.java:4134)
at com.android.server.pm.PackageManagerService.isOrphaned(PackageManagerService.java:18757)
at...
所以看起来这个包甚至没有部署在手机上
包名称以小写字母开头，没问题。
我查看了构建日志，并看到以下消息之一：

（对不起，如果在例外情况下有一些无意义，我翻译了它）
似乎Visual Studio或ADB 在手机上部署应用程序时遇到一些麻烦，原因是什么？我尝试更换USB端口，但我也没有运气。
我尝试创建一个新的Blank Xamarin.Android解决方案和Native Portable解决方案并部署它们，但它对我没有用。
我不知道此时该怎么做。我应该重置工厂吗？
