xamarin.forms googlemaps infowindow click open new page

Question

in my Xamarin.Forms App I have an Page which indicates an GoogleMap. Everything is working perfect, but when I click on an InfowWindow from a pin, i cant open a new detailpage. The App hangs and I can do nothing with the App. I get no error message.

But its working in iOS.

Heres the Code:

private void MapObjekt_InfoWindowClicked(object sender, InfoWindowClickedEventArgs e)
        {
            App.locator.StopListeningAsync();
            App.locator.PositionChanged -= Locator_PositionChanged;

            objektliste detailPage = new objektliste();
            App.mdp.Detail = detailPage;
        }

Whats my fault ?

Answer 1

问题是，我必须像这样在Mainthread中打开Page：

Device.BeginInvokeOnMainThread(() => { App.mdp.Detail = detailPage; });
