Answer 1

had the same problem on windows 64 bit i'm using the latest android sdk build tools at this moment (v25.0.1) just installed jdk 9 and a 32 bit version of jdk(version 7) due to this link

then changed the jdk path in tools>options>Xamarin>Android settings. restart visual studio. clean and rebuild. that's it.

Answer 2

You may have wrongly selected "target Android version" to version your emulator is running on.

Make sure that these two are aligning.

VS -> (right click on project) -> properties - > Android Manifest (tab) -> Target Android version (drop down)

Answer 3

In my system, I'm using latest Android SDK build tools at this moment(v26.0.1) and Visual Studio 2017 Version 15.7.4.

In Regedit the Android SDK also same Visual Studio tools>options>Xamarin>Android settings. But the problem was same with me.

In my case, I changed the Package Name in Android Manifest then the problem has been solved.
