Xamarin Android App begegnet Klasse nicht gefunden ... auf Pfad: DexPathList [[ZIP-Datei ...] ...]

Question

Ich habe einen Fehler, wenn ich versuche, die folgende Codezeile in einem Xamrin auszuführen Android App:

EntityEditor ee = new EntityEditor(); 

die EntityEditor-Klasse ist eine DialogFragment, dessen Code sieht wie folgt aus:

namespace Storyvoque 
{ 
    public class EntityEditor : DialogFragment 
    { 
     EditText entityId; 
     EditText entityType; 
     EditText entityName; 
     EditText entityDescription; 
     EditText containerEntityId; 
     AutoCompleteTextView containerEntityName; 
     EditText targetEntityId; 
     AutoCompleteTextView targetEntityName; 
     EditText destinationEntityId; 
     AutoCompleteTextView destinationEntityName; 
     EditText entityOwner; 
     EditText entityDate; 
     CheckBox syncPending; 

     public StoryEntity editData; 

     public override void OnCreate(Bundle savedInstanceState) 
     { 
     base.OnCreate(savedInstanceState); 

     // Create your fragment here 
     } 

     public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
     { 
     return inflater.Inflate(Resource.Layout.EntityEditor, container, false); 
     } 

     public override void OnViewCreated(View view, Bundle savedInstanceState) 
     { 
     entityId = (EditText)View.FindViewById(Resource.Id.entityId); 
     entityType = (EditText)View.FindViewById(Resource.Id.entityType); 
     entityName = (EditText)View.FindViewById(Resource.Id.entityName); 
     entityDescription = (EditText)View.FindViewById(Resource.Id.entityDescription); 
     containerEntityId = (EditText)View.FindViewById(Resource.Id.containerEntityId); 
     containerEntityName = (AutoCompleteTextView)View.FindViewById(Resource.Id.containerEntityName); 
     targetEntityId = (EditText)View.FindViewById(Resource.Id.targetEntityId); 
     targetEntityName = (AutoCompleteTextView)View.FindViewById(Resource.Id.targetEntityName); 
     destinationEntityId = (EditText)View.FindViewById(Resource.Id.destinationEntityId); 
     destinationEntityName = (AutoCompleteTextView)View.FindViewById(Resource.Id.destinationEntityName); 
     entityOwner = (EditText)View.FindViewById(Resource.Id.entityOwner); 
     entityDate = (EditText)View.FindViewById(Resource.Id.entityDate); 
     syncPending = (CheckBox)View.FindViewById(Resource.Id.syncPending); 

     base.OnViewCreated(view, savedInstanceState); 
     } 

     public void LoadData(StoryData source, UserData users, StoryEntity data) 
     { 
     entityId.Text = data.EntityId.ToString(); 
     entityType.Text = data.EntityType.ToString(); 
     entityName.Text = data.Name; 
     entityDescription.Text = data.Text; 
     containerEntityId.Text = data.Container.ToString(); 
     containerEntityName.Text = source.GetWrapper(data.Container)?.Name ?? string.Empty; 
     targetEntityId.Text = data.Target.ToString(); 
     targetEntityName.Text = source.GetWrapper(data.Target)?.Name ?? string.Empty; 
     destinationEntityId.Text = data.Destination.ToString(); 
     destinationEntityName.Text = source.GetWrapper(data.Destination)?.Name ?? string.Empty; 
     entityOwner.Text = users[data.UserNum]?.DisplayName ?? data.UserNum.ToString(); 
     entityDate.Text = data.Date.ToLocalTime().ToString("G"); 
     syncPending.Checked = data.SyncRequired; 
     } 

     public void StoreData(StoryEntity data) 
     { 
     data.EntityId = Int32.Parse(entityId.Text); 
     data.Name = entityName.Text; 
     data.Text = entityDescription.Text; 
     data.Container = Int32.Parse(containerEntityId.Text); 
     data.Target = Int32.Parse(targetEntityId.Text); 
     data.Destination = Int32.Parse(destinationEntityId.Text); 
     } 

     public override void OnDismiss(IDialogInterface dialog) 
     { 
     StoreData(editData); 
     base.OnDismiss(dialog); 
     } 
    } 
} 

ich nehme an wir nicht an der AXML Datei suchen müssen, weil sie nie die Funktion OnCreatedView erreicht, bevor Der Fehler tritt auf. Die Aufrufliste des Fehlers sieht so aus:
