Cannot create Android project in xamarin

Issue

I have installed visual studio ultimate 2012 with Xamarin. I have set JDK, sdk and ndk path correctly. I have even set JAVA_HOME path correctly to jdk 1.7. when I tried to create new Android project, It gives me an error "Object reference not set to an instance of an object". The output is as below
