问题 Using VS2015/Windows 10, I created a Blank App (Portable) and set the startup project to Droid. I had only one emulator by default, so I created a Galaxy Nexus/API 23/Intel Atom x86 using the AVD with HAXM. I can't get this blank project to run on either emulator. When I hit debug, it goes through the motions and starts the emulator but nothing happens.

问题 I'm developing a Xamarin Forms application(currently only Android support). The default setup set TargetFramework to 7.1. The minimum android version for this project must be 7.0. This produces a warning: The $(TargetFrameworkVersion) for Xamarin.Forms.Platform.Android.dll (vv7.1) is greater than the $(TargetFrameworkVersion) for your project (v7.0). You need to increase the $(TargetFrameworkVersion) for your project. It seems natural to me, to compile for the version that you will be using.
