Have an "'Resource.Attribute' does not contain a definition for 'actionBarSize'" error

Question

Was trying to debug an empty app and got "'Resource.Attribute' does not contain a definition for 'actionBarSize'" error. I have reinstalled android SDK's.

    public static void UpdateIdValues()
    {
        global::Xamarin.Forms.Platform.Android.Resource.Attribute.actionBarSize = global::L1NQ.Droid.Resource.Attribute.actionBarSize;
    }
    public partial class Attribute
    {

        static Attribute()
        {
            global::Android.Runtime.ResourceIdManager.UpdateIdValues();
        }

        private Attribute()
        {
        }
    }

Answer 2

I had the same problem (and various more) after create a new .forms project (shared) with VS2015 Update 3 RC. To the JDK 7, I had installed the version:
Java SE Development Kit Update 55

After I have downloaded and installed
Java SE Development Kit Update 79

from: Download JDK 7 - Update 79

and rebooted my machine
this problem (an various further problems) has gone.
