MonoDroid: Fragment.Instantiate ClassNotFoundException

I am trying to create a swipping tab view using the ActionBar in Mono for Android. The adroid for eclipse plugin has this as a default project template and I have manage to convert it over, I am now trying to add the functionally to separate my fragments out. When I try to run my project I get a ClassNotFoundException Here is the code for the Fragment ``` using Fragment = Android.Support.V4.App.Fragment; namespace MobileCompanion.AndroidOS.App.UI.Customers { public class HomeTab : Fragment { public override Android.Views.View OnCreateView(Android.Views.LayoutInflater inflater, Android.Views.ViewGroup viewGroup, Android.OS.Bundle p2) { return null; } } } ``` and here is my section adapter ``` using System.Collections.Generic; using Android.Content; using Android.OS; using Android.Support.V4.App; using Java.Lang; namespace MobileCompanion.AndroidOS.App { public class SectionsPagerAdapter : FragmentPagerAdapter { private readonly Context _context; public readonly IList<TabInfo> Tabs = new List<TabInfo>(); private Bundle _bundle; public SectionsPagerAdapter(FragmentManager fm, Context context, Bundle savedInstanceState) : base(fm) { this._context = context; this._bundle = savedInstanceState; } public override Fragment GetItem(int i) { var args = new Bundle(); var page = Fragment.Instantiate(this._context, typeof(HomeTab).FullName); // var page = new HomeTab(); <<--- Work but nothing displayed as none of the create methods are run page.Arguments = args; return page; } public override int Count { get { return this.Tabs.Count; } } public override ICharSequence GetPageTitleFormatted(int p0) { return new String(this.Tabs[p0].PageTitle); } } } ``` Java.Lang.RuntimeException: Unable to instantiate fragment MobileCompanion.AndroidOS.App.UI.Customers.HomeTab: make sure class name exists, is public, and has an empty constructor that is public at Android.Runtime.JNIEnv.CallStaticObjectMethod (intptr,intptr,Android.Runtime.JValue[]) [0x00024] in /Users/builder/data/lanes/monodroid-mac-monodroid-4.2.4-branch/9f7cbd60/source/monodroid/src/Mono.Android/src/Runtime/JNIEnv.g.cs:767 at Android.Support.V4.App.Fragment.Instantiate (Android.Content.Context,string) [0x00034] in /Users/builder/data/lanes/monodroid-mac-monodroid-4.2.4-branch/9f7cbd60/source/monodroid-bindings/Compatibility-v4/bindings/obj/platform-14/src/generated/Android.Support.V4.App.Fragment.cs:624 at MobileCompanion.AndroidOS.App.SectionsPagerAdapter.GetItem (int) [0x00007] in c:\Projects\MobileCompanion\trunk\MobileCompanion.Android.App\SectionsPagerAdapter.cs:28 at Android.Support.V4.App.FragmentPagerAdapter.n_GetItem_I (intptr,intptr,int) [0x00008] in /Users/builder/data/lanes/monodroid-mac-monodroid-4.2.4-branch/9f7cbd60/source/monodroid-bindings/Compatibility-v4/bindings/obj/platform-14/src/generated/Android.Support.V4.App.FragmentPagerAdapter.cs:56 at (wrapper dynamic-method) object.780b3637-f853-4d6e-8435-9c92bc6a9dd5 (intptr,intptr,int) --- End of managed exception stack trace --- android.support.v4.app.Fragment$InstantiationException: Unable to instantiate fragment MobileCompanion.AndroidOS.App.UI.Customers.HomeTab: make sure class name exists, is public, and has an empty constructor that is public ``` at android.support.v4.app.Fragment.instantiate(Fragment.java:395) at android.support.v4.app.Fragment.instantiate(Fragment.java:363) at ``` mobilecompanion.androidos.app.SectionsPagerAdapter.n_getItem(Native Method) ``` at ``` mobilecompanion.androidos.app.SectionsPagerAdapter.getItem(SectionsPagerAdapter.java:30) ``` at ``` android.support.v4.app.FragmentPagerAdapter.instantiateItem(FragmentPagerAdapter.java:97) ``` at android.support.v4.view.ViewPager.addNewItem(ViewPager.java:692) at android.support.v4.view.ViewPager.populate(ViewPager.java:821) at android.support.v4.view.ViewPager.populate(ViewPager.java:772) at android.support.v4.view.ViewPager.onMeasure(ViewPager.java:1234) at android.view.View.measure(View.java:12723) at ``` android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:4698) ``` at android.widget.FrameLayout.onMeasure(FrameLayout.java:293) at android.view.View.measure(View.java:12723) at ``` android.widget.LinearLayout.measureVertical(LinearLayout.java:812) ``` at android.widget.LinearLayout.onMeasure(LinearLayout.java:553) at android.view.View.measure(View.java:12723) at ``` android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:4698) ``` at android.widget.FrameLayout.onMeasure(FrameLayout.java:293) at ``` com.android.internal.policy.impl.PhoneWindow$DecorView.onMeasure(PhoneWindow.java:2092) ``` at android.view.View.measure(View.java:12723) at ``` android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1064) ``` at android.view.ViewRootImpl.handleMessage(ViewRootImpl.java:2442) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4424) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at ``` com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) ``` at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) at dalvik.system.NativeStart.main(Native Method) ``` Caused by: java.lang.ClassNotFoundException: MobileCompanion.AndroidOS.App.UI.Customers.HomeTab ``` at ``` dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:61) ``` at java.lang.ClassLoader.loadClass(ClassLoader.java:501) at java.lang.ClassLoader.loadClass(ClassLoader.java:461) at android.support.v4.app.Fragment.instantiate(Fragment.java:385) ```
