Question

In a Visual Studio 2015, Xamarin, Android SDK, jdk 1.7, and emulator are installed and Xamarin has all green checked items in tools>options>Xamarin. But When I try to create Blank App (Android) VS shows an error:

Object reference not set to an instance of an object

Then new project fail to create and solution explorer will be empty.

How could I solve it?

I solved it with updated Android SDK setup (API Level 19 and 21) [3rd party] to Android SDK setup (API Level 22) [3rd party] in Visual Studio setup.
