I'm trying to set up the sample android application from https://github.com/telerik/Android-samples

I cloned the Git repo and am obviously missing the Telerik libraries needed for the application.

When I try to install the Telerik libraries using Nuget Package Manager, I get the following error:

"Severity    Code    Description    Project    File    Line    Suppression State
Error        Could not install package 'Xamarin.Android.Support.Animated.Vector.Drawable 25.1.0'. You are trying to install this package into a project that targets 'MonoAndroid,Version=v6.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author."

It seems that the project is broken, or doesn't work with VS 2019, because I am definitely not targeting v6.0 and the error doesn't change when I change target versions (both manifest and build versions).

I tried opening the project in VS 2017, but received a message that the project is incompatible and should be opened in VS 2015 or earlier.

The sample app hasn't been updated on GitHub for at least 2 years.

Is there any plans to update these samples to work on current dev environments?

Hello Dan,

That repository is for a product that was discontinued a few years ago, UI for Android. Learn more in this blog post http://www.telerik.com/android-ui-sunsetting 

Telerik UI for Xamarin

We do have another product with which you can build for Android, Telerik UI for Xamarin. I've listed some of the resources below:

Telerik UI for Xamarin Documentation

  • Look under the Xamarin.Forms Controls section. You can deploy to iOS, Android and Windows 10 (UWP) with the same UI with all of those.
  • If you do not want to use Xamarin.Forms, then review the documentation under the Native Controls Wrappers section.
    • You can directly use these in a non-Xamarin.Forms app, however the control availability is limited because all of development efforts are focused for Xamarin.Forms (because you can deploy to all the platforms at the same time)

Xamarin Demo Applications

  1. Telerik UI for Xamarin Samples Application (this is a highly polished app you see in the app stores)
  2. SDK Browser Application (this contains all the feature examples from the documentation)
  3. Native-only Examples

Complete Real-World Application Demos

We have also build out four fully implemented complete real-world application that you can use for enterprise or consumer facing scenarios. They leverage everything from SQL server, REST API, Custom AI and more.

Tip - Be sure to visit the README page for each of those demos in GitHub as they fully walk you though the setup.

You can also read my blog post series on how I built the CRM application.

I hope this helps clear things up.
