I tried searching for the same error with no results so here's my question:
I have a Xamarin form project that will be deployed on Android and iOS. In one of my views i have 2 buttons that will only be visible if the user has selected a few option first. This is working just fine on iOS, but when I deploy on the Android simulator the buttons are not being displayed unless I switch orientations. Here's a sample of the code:
<Button
Grid.Column="0"
Grid.Row="0"
TextColor="{StaticResource AwesomeTxtColor}"
Text="Click Me"
BackgroundColor="{StaticResource AwesomeBgColor}"
IsVisible="{Binding SelectedIndex, Converter={StaticResource isGreaterOrEqualZero}}"
Command="{Binding AwesomeCommand}" />
Again, converter is working per debugging session and bindings too. The issue is only happening for me on Android. iOS is working as expected. Xamarin Forms version: 2.3.4.267. Anyone have experienced this before or have any ideas on what might be the problem?
It turned out that it was a threading issue. Lists used to populate pickers on my view were loaded using:
await Task.Run(() => {
//API calls to load lists
});
I changed that to:
Device.BeginInvokeOnMainThread(() => {
//API calls to load lists
});
And now Android updates the UI. Odd but apparently those values on the lists were stuck on a different thread...
