Xamarin/Visual Studio 2017 app deploys successful, but no app shows in the android emulator?

When I build and deploy my app in Xamarin/Visual Studio 2017, the build-output outputs the following:

Restoring NuGet packages...
To prevent NuGet from restoring packages during build, open the Visual Studio Options dialog, click on the Package Manager node and uncheck 'Allow NuGet to download missing packages during build.'

The app seems to be build and deployed successfully, but the app does never show up anywhere on the android emulator?

When I first created the .Driod project, I could run the Hello World-app just fine.

I fixed this just now by going to the Android Options, selecting Advanced Properties and adding x86 to the supported architectures. Then start the emulator from AVD Android Emulator Manager. After it starts, debug the app. Good luck.
