Error building helloWorld application using xamarin.Forms

I am trying to run the hello forms application that visual studio creates when you select the Xamarin.Forms template.But I am getting lots of errors when I try to start the android version of the application.Here are some of the errors that I get :

Activate(java.lang.String,java.lang.String,java.lang.Object,java.lang.Object[]) in mono.android.TypeManager cannot be applied to (java.lang.String,java.lang.String,md5d4dd78677dce656d5db26c85a3743ef3.CarouselPageAdapter,java.lang.Object[])
mono.android.TypeManager.Activate ("Xamarin.Forms.Platform.Android.CarouselPageAdapter, Xamarin.Forms.Platform.Android, Version=1.3.3.0, Culture=neutral, PublicKeyToken=null", "", this, new java.lang.Object[] { });

cannot find symbol
symbol : method getClass()
location: class md5d4dd78677dce656d5db26c85a3743ef3.CarouselPageAdapter
if (getClass () == CarouselPageAdapter.class)

package android.support.v4.content.Loader does not exist
android.support.v4.content.Loader.OnLoadCompleteListener

all the other errors(total of 30) are like the errors above only with different class names.I already updated the support library from the android sdk manager but I still get these errors.What do you suggest I do?
