title: How to solve: Warning XBD100: ItemGroup `XamarinBuildDownloadRestoreAssemblyAar` is no longer supported. Xamarin Android Project
body: <p>I install from NuGet package manager <code>Xamarin.GooglePlayServices.Ads</code> and after trying to debug I receive this error:</p>
  <pre><code>Warning XBD100: ItemGroup `XamarinBuildDownloadRestoreAssemblyAar` is no longer supported.  If your build is failing, revert to an older Xamarin.Build.Download version, or migrate your packages to use the new `XamarinBuildDownloadAndroidAarLibrary` ItemGroup.  If your build is succeeding it is safe to ignore this warning. (XBD100) (WeatherLocationInfo.Android)
  </code></pre>
  <p>When I click on the warning send me on file <code>Xamarin.Build.Download.targets</code> on this part of the code:</p>
  <pre><code>&lt;Target Name=&quot;_XamarinBuildDownloadAarRestore&quot;
      Condition=&quot;'@(XamarinBuildDownloadRestoreAssemblyAar)'!=''&quot;
      DependsOnTargets=&quot;_XamarinBuildDownload&quot;&gt;
      &lt;Warning
          Code=&quot;XBD100&quot;
          Text=&quot;ItemGroup `XamarinBuildDownloadRestoreAssemblyAar` is no longer supported.  If your build is failing, revert to an older Xamarin.Build.Download version, or migrate your packages to use the new `XamarinBuildDownloadAndroidAarLibrary` ItemGroup.  If your build is succeeding it is safe to ignore this warning.&quot;
          /&gt;
  &lt;/Target&gt;
  </code></pre>
  <p>Is there a way to solve the problem ?</p>
