Crash in Android

[rotorgames]

Hi. Thank you for awesome plugin but I have a problem with it.

I have error in Android when I added CarouselView in layout.

Xamarin.VS 4.2.0.680 Xamarin.Forms to 2.3.2.127 Android 6.0

P.S. Crash is only if I use nuget package in my project. When I deploy your demo project that all working.

<abstractions:CarouselViewControl  Position="0" ItemsSource="{Binding MyList}" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">
  <abstractions:CarouselViewControl.ItemTemplate>
    <DataTemplate>
      <Label Text="{Binding .}"/>
     </DataTemplate>
   </abstractions:CarouselViewControl.ItemTemplate>
</abstractions:CarouselViewControl>

Yes, i merged your fix. I new package is on the way as soon as i solve a pending issue in Android. Thanks

@alexrainman Please. Do code review in your repository. When I fixed this problem I had more problems with obj, bin and packages folders. Any changes in it are added to commit that's why I don't see real changes. Thx

[alexrainman]

?

[rotorgames]

@alexrainman Delete all obj, bin, packages folders and create gitignore

[alexrainman]

I know those are extra files but, what real problem you have with them?

This is what i have done that is community visible:

• Alex has been pretty active sharing his knowledge and answering questions in StackOverflow, GitHub and Xamarin Forums.
• Alex has been open sourcing Xamarin components and plugin with the community, with more of 10 repositories being maintained on GitHub.
• One of Alex's Xamarin.Forms plugin, the CarouselView, is currently being pulled into the Xamarin.Forms core (xamarin/Xamarin.Forms#853). As an stable widget, this control has become the standard for Xamarin.Forms carousel screens with more that 16K downloads in NuGet and more than 100 solved and not open issues.
• Another Alex's plugin, the SegmentedControl (https://github.com/alexrainman/SegmentedControl), is a big candidate to be also pulled into Xamarin.Forms core.
• Plus Xamarin.Forms UI related plugins, Alex shares plugins to set app icon Badge, Google Analytics and KeyChain access.
• Alex shares his knowledge about cutting edge technologies like Couchbase NoSQL and MobileIron integration with Xamarin Apps.
