无法启动应用程序

我无法使我的应用程序从Visual Studio 2015 / Xamarin运行Android设备。它无法在设备上启动，并显示以下消息：

The application could not be started.
Ensure that the application has been installed to the target device and has a launchable activity (MainLauncher = true).  
Additionally, check Build->Configuration Manager to ensure this project is set to Deploy for this configuration.

因此，我将装饰器添加[Activity(MainLauncher = true)]到MainActivity中。

我检查了中的Build-> Configuration ManagerAnyCPU，Build和Deploy。

重新启动，结果相同，未在设备上启动，并给出了相同的消息。

StackOverflow上的一则文章表明以前的应用程序可能尚未完全删除，因此请从adb shell发出以下命令：

adb -s 09103e9 shell pm list packages 

显示设备上的软件包：

这些都不是应用程序。网络上的一些建议是删除Mono软件包，因此我使用以下命令删除了它们：

adb -s 091930e9 shell pm uninstall -k Mono.Android.Platform.ApiLevel-23
adb -s 091930e9 shell pm uninstall -k Mono.Android.DebugRuntime

但这没有效果。从Visual Studio启动应用程序后，将重新安装该应用程序。

在VS中MyProject.Native.Droid properties > Android Options > Packaging，未选中“使用快速部署”（仅调试模式）无效。

在VS中MyProject.Native.Droid properties > Android Options > Advanced，验证是否已检查x68。

查看@hvaughn建议的生成输出，有以下警告，这也是错误列表中的警告：

Found conflicts between different versions of the same dependent assembly. 
In Visual Studio, double-click this warning (or select it and press Enter) to fix the conflicts; otherwise, add the following binding redirects to the "runtime" node in the application configuration file:
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly><assemblyIdentity name="System.Net.Http" culture="neutral" publicKeyToken="b03f5f7f11d50a3a" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" /></dependentAssembly></assemblyBinding> 
    MyProject.Native.Droid          
    One or more dependent assemblies have version conflicts

在错误列表中还显示：

Do you want to fix these conflicts by adding binding redirrect records in the application configuration file?

我单击是。然后，此警告消失，直到下一次构建并再次出现，因此这无效。

然后是这样的：

:Deployment failed
Mono.AndroidTools.InstallFailedException: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]
   at Mono.AndroidTools.Internal.AdbOutputParsing.CheckInstallSuccess(String output, String packageName)
   at Mono.AndroidTools.AndroidDevice.<InstallPackage>c__AnonStoreyD.<>m__0(Task`1 t)
   at System.Threading.Tasks.ContinuationTaskFromResultTask`1.InnerInvoke()
   at System.Threading.Tasks.Task.Execute()
Deployment failed because of an internal error: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]
InternalError
Build succeeded.
Deploy successfully on Google Nexus 7

这发生在2台设备上，即Google Nexus 7和Samsung SM-T530NU。

该代码来自远程Git存储库。

根据@Matt的建议，我创建了一个新的Hello World类型的解决方案，并将其安装在设备上。

不确定该怎么做，网络上针对此错误的建议是删除该应用程序，我使用了该应用程序，adb如上所示。我也对“部署成功...”消息感到困惑，因为它不在设备上。

编辑

解决的办法是恢复出厂设置。这告诉我，尽管我采取了各种步骤删除应用程序/程序包，但它仍然以某种方式存在。
