XLabs Android.OS.BaseBundle

hey guys

im getting this on xlabs for media picker?

   Missing method GetString in assembly /storage/emulated/0/Android/data/CoRE.Mobile/files/.__override__/XLabs.Platform.Droid.dll, type Android.OS.BaseBundle
    The class Android.OS.BaseBundle could not be loaded, used in XLabs.Platform.Droid

ive implemented the resolver container as most people have

private void SetIoc()
        {
            var resolverContainer = new SimpleContainer();

            var app = new XFormsAppDroid();

            app.Init(this);

            var documents = app.AppDataDirectory;
            var pathToDatabase = Path.Combine(documents, "xforms.db");

            resolverContainer.Register<IDevice>(t => AndroidDevice.CurrentDevice)
                .Register<IDisplay>(t => t.Resolve<IDevice>().Display)
                .Register<IJsonSerializer, XLabs.Serialization.JsonNET.JsonSerializer>()
                .Register<ITextToSpeechService, TextToSpeechService>()
                .Register<IDependencyContainer>(resolverContainer)
                .Register<IXFormsApp>(app)
                .Register<ISecureStorage>(t => new KeyVaultStorage(t.Resolve<IDevice>().Id.ToCharArray()))
                .Register<ISimpleCache>(
                    t => new SQLiteSimpleCache(new SQLite.Net.Platform.XamarinAndroid.SQLitePlatformAndroid(),
                        new SQLite.Net.SQLiteConnectionString(pathToDatabase, true), t.Resolve<IJsonSerializer>()));


            Resolver.SetResolver(resolverContainer.GetResolver());
        }

i have the permissions

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

along with some others
i even went as far as copying the MediaPicker and MediaPickerActivity files out of labs like some people have suggested...with

                .Register<IMediaPicker>(t => new CoRE.Mobile.Services.MediaPicker())

no such luck

currently using Xamarin.Forms 1.3.4 and XLabs 2.0, i did try on another git branch upgrading it to latest builds but same issue
running on an Android 4.2.1 tablet?

anyone got any suggestions?
