Problem with Xamarin with Visual Studio 2015

I installed Visual Studio 2015 with Xamarin and when I create a blank app I try to run it without changing anything and it displays an "implementation error" in Output it says : 2> it was attemped a numerical comparison in "$(_DeviceSdkVersion)" that evaulates "" instead of a number, in the condition "$(_DeviceSdkVersion) >=21". Please help me, I want to learn but can't even run the default app 😣

If anyone else need the answer: You need to look in Android SDK Manager the SDK Path. That path has to be in Tools, Options, Xamarin, Androis Settings, Android SDK Location (and after you change that have to save, close and open again to try). Also should look in microsoft page for the solution of emulator problems, I used both things 😉


Thank you, It was really usefull to understeand the real problem, I resolved it different cause I don't have Genymotion but I finally could run it!!


I think this can help you. I do not know how to solve this problem, but enjoyed their doubts because I am also studying development with Xamarin.
