I have an Android app which uses:

  • ActionBarSherlock Xamarin component
  • MvvmCross fragment support.

I just upgraded to MvvmCross 3.1.1 and I get some errors:

Error 2 The type 'Android.Support.V4.App.Fragment' is defined in an assembly that is not referenced. You must add a reference to assembly 'Xamarin.Android.Support.v4, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

Error 3 The type 'Android.Support.V4.App.FragmentActivity' is defined in an assembly that is not referenced. You must add a reference to assembly 'Xamarin.Android.Support.v4, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

I delete bin and obj folders just to be sure and rebuilt, same errors.

If I add the Android Support Library v4 Xamarin component, I get a many errors like

Error 11 The type 'Android.Support.V4.App.ActionBarDrawerToggle' exists in both 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v4.3\Mono.Android.Support.v4.dll' and '..\xamandroidsupportv4-18-4.18.1\lib\android\Xamarin.Android.Support.v4.dll' ..MyActionBarDrawerToggle.cs 19 44

If I remove the Mono.Android.Support.v4 I got error which asks me to put it back.

You need to move so that all your libraries which use the newly branded Xamarin support assemnbly - see bugzilla.xamarin.com/show_bug.cgi?id=15205 - Stuart
thanks Stuart but I don't understand what I should do. Do I need to recompile MvvmCross Droid Fragging plugin from source code? - Andrei N.
Also, I don't understand what has changed with the latest version of MvvmCross, why didn't I have this problem before? - Andrei N.

thanks. problem is ActionBarSherlock Xamarin component is build with Mono.Android v4. I tried to replace it with Xamarin Android v4 and the sample doesn't work. And I am in hurry with getting a new build. I'm now considering reverting back to the previous version of Mvvmcross. - Andrei N.

It seems you have an old version of ActionBar Sherlock component that references Mono.Android.Support.v4, the latest version 4.4.0.2 uses the new Android Support Library.

Hope this helps.
