Black screen appears when use process attribute in monodroid activity

Issue

From one activity my app will go to a second activity (I send some of this activities code here). This activity has a mapview. because that I have 2 mapview in my app I should to use 'Process' attribute in this activity.but when I use this attribute before lunching the activity app displays a black screen for some seconds and then my ProgressDialog and activity will display. I wanna that this black screen not appear

This is the definition of my class:

    [Activity (Label = "PropertyShowActivity",
           Process =":PropertyShowMapActivity")]            
public class PropertyShowActivity : MapActivity
{.....}

The onCreate code of this activity is:

protected override void OnCreate (Bundle bundle)
    {
        try {
            base.OnCreate  (bundle);

            RequestWindowFeature (WindowFeatures.NoTitle);
            PD = new ProgressDialog (this);
            PD.SetMessage ("Please Wait...");
            PD.Indeterminate = true;
            PD.SetCancelable (false);
            PD.Show ();
            currentproperty = new Property ();
            SetContentView (Resource.Layout.PropertyShow);
            mapLayout = FindViewById ,,,,<LinearLayout > (Resource .Id.PrptyLocationOnMapLayout);
            mapLayout .Visibility = ViewStates.Gone;



            if (RplSettings.Sitename == string.Empty) {
                RplSettings.LoadAllSettings (this);
            }
            action = Intent.GetStringExtra (AppConstants.Action);
            Pid = Intent.GetLongExtra ("Pid", 0);

            Common .MenuInitialize (this, "Property");
            Common .MenuEventInitialize (this);
            AssignBottomActionBarEvents ();

            FindElemnts ();

            if (Pid == 0)
                Pid = Intent.GetIntExtra ("Pid", 0);

            if (action == string.Empty) {
                PD.Hide ();
                Finish ();
            }
            if (action == AppConstants.DownloadProperty) {
                LoadPropertyData ();
            } else if (action == AppConstants.OfflineProperty) {
                OfflineProperty = true;
                //var path = Intent.GetStringExtra (AppConstants.PropertyFilePath);
                //currentproperty = IOAddOn.ParsePropertyJsonString (UTF8Encoding.UTF8.GetString (Property.LoadPropertyFromSD (path)));
                LoadPropertyData ();
            }


        } catch (Exception ex) {
            Common.HandleException (ex);
        }
    }

and also the logs of ddms is: when I define my class such as below it works fine:

[Activity (Label = "PropertyShowActivity")]         
public class PropertyShowActivity : MapActivity
{.....}

Solution

I resolved it bur running two app in same process.But after going to second activity i saved the state of new app in application class of app. and then when I back tp first map activity in OnResume i change the state of mapview to the past state. It work right.
