Error on Android when SetPage(new MyMasterDetailPage()) "DrawerLayout must be measured with..."

Hi,

I've got an issue when I use the SetPage() method in my Android MainActivity and try to set a MasterDetailPage. The error message I get is:

Java.Lang.IllegalArgumentException: DrawerLayout must be measured with MeasureSpec.EXACTLY.

I try to implement something similair as this example. However when I try to implement it, I get this error. The strange thing is that this happens even when I have a completely empty MasterDetailPage (except from the required parts). I also tried copying the MasterDetailPage from the example but that didn't work either.

When I use SetPage() to another regular ContentPage, it works fine.

(I am using Xamarin 1.2.2)

The MasterDetailPage, MainPage (PCL)

<?xml version="1.0" encoding="utf-8" ?>
<MasterDetailPage xmlns="http://xamarin.com/schemas/2014/forms"
  xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
  x:Class="//namespace//.Views.MainPage"
  Title="aaaa">

  <MasterDetailPage.Detail>
    <ContentPage Title="Main">
      <ContentPage.Content>
        <Label Text="bbbb" />
      </ContentPage.Content>
    </ContentPage>
  </MasterDetailPage.Detail>

  <MasterDetailPage.Master>
    <ContentPage Title="Menu">
      <ContentPage.Content>
        <Label Text="aaaa" />
      </ContentPage.Content>
    </ContentPage>
  </MasterDetailPage.Master>
</MasterDetailPage>

MainActivity.cs (Android Project)

[Activity(Label = "App Name", MainLauncher = true, Theme = "@android:style/Theme.Holo.Light", ConfigurationChanges=Android.Content.PM.ConfigChanges.Orientation | Android.Content.PM.ConfigChanges.ScreenSize)]

    public class MainActivity : AndroidActivity, IRootPageManager
    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            Xamarin.Forms.Forms.Init(this, bundle);

            SetPage(App.GetSplashPage(this));
        }

        public void ShowMainPage()
        {
            SetPage(App.GetMainPage(this));
        }

        public void ShowLoginPage()
        {
            SetPage(App.GetLoginPage(this));
        }
    }
