InvalidCastException on Android #7

Closed guyeeba closed 6 years ago

guyeeba commented 6 years ago

Hi,

I receive an InvalidCastException on Android (UWP and iOS builds work fine).

Both Emulator (6.0.0) and physical device (7.0) is affected. Latest Xamarin.Forms, Visual Studio, everything.

Stack trace:

I narrowed the relevant XAML down to this, but I still get the exception:

    <segmentctrl:SegmentedControl
      x:Name="PositionCtrl" 
      Grid.Row="2"
      SelectedTextColor="White"
      Margin="8,8,8,8">
      <segmentctrl:SegmentedControl.Children>
         <segmentctrl:SegmentedControlOption Text="a"/>
         <segmentctrl:SegmentedControlOption Text="b"/>
      </segmentctrl:SegmentedControl.Children>
    </segmentctrl:SegmentedControl>

Thanks!

Thank you for the feedback.

Unfortunately I can't reproduce the error. Does it fail if you try and run the Android test included in this GitHub repo?

Any chance you create a small project where you provoke the error and share that with me?

1iveowl commented 6 years ago

I did some changes and released version 1.0.6.

Not sure if it helped, as I'm still not able to reproduce. Let me know if version 1.0.6 made any difference.

Thank you.

Well, whatever you did, it helped...

Thanks a lot!

I added the latest release of the Android libraries and recompiled. It must have been some error in the Xamarin libraries.

Glad it helped.
