Problems with plugins

Hi, I’m really new, and I’m creating a simple game for android, and I was trying to add some achievements and leaderboard from google play and some IAP, but after I import my package for these plugins the console show me this error:

ResolutionException: Cannot find candidate artifact for com.android.support:support-v4:25.2.0
Google.JarResolver.PlayServicesSupport.GetDependencies (Google.JarResolver.Dependency dep, System.Collections.Generic.List1 repoPaths) Google.JarResolver.PlayServicesSupport.GetTransitiveDependencies (System.Collections.Generic.Dictionary2 dependencies, System.Collections.Generic.List1 repoPaths) Google.JarResolver.PlayServicesSupport.FindMissingDependencyPaths (System.String destinationDirectory, System.Collections.Generic.Dictionary2& dependencyPaths, Google.JarResolver.ExplodeAar explodeAar)

GooglePlayServices.PlayServicesResolver.AutoResolve ()
UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at C:/buildslave/unity/build/artifacts/generated/common/editor/EditorApplicationBindings.gen.cs:197)

What could I do?

I experienced the same issue today. The solution was rather simple but I decided to come back here to share it anyways since many people seem to be having the same problem.

To fix the problem, simply check that you have all the required pieces of the Android SDK installed. Although
the Android Support Repository is not listed as a required dependency in the Google Play Games plugin’s Github page, it is required.
