java Google Play Services Unity

Question

我正在尝试使用谷歌推出的Jar解析器来添加Google Play服务-https://github.com/googlesamples/unity-jar-resolver来创建一个我们可以重用的插件，以便轻松地将Google Play服务添加到我们的项目中

我创建了他们的示例依赖类的副本：

    // Setup the resolver using reflection as the module may not be

    Type playServicesSupport = Google.VersionHandler.FindClass(
      "Google.JarResolver", "Google.JarResolver.PlayServicesSupport");
    if (playServicesSupport == null) {
      return;
    }
    svcSupport = svcSupport ?? Google.VersionHandler.InvokeStaticMethod(
      playServicesSupport, "CreateInstance",
      new object[] {
          "GooglePlayGames",
          EditorPrefs.GetString("AndroidSdkRoot"),
          "ProjectSettings"
      });

    // For example to depend on play-services-games version 9.6.0  you need to specify the
    // package, artifact, and version as well as the packageId from the SDK manager in case
    // a newer version needs to be downloaded to build.

    Google.VersionHandler.InvokeInstanceMethod(
      svcSupport, "DependOn",
      new object[] {
      "com.google.安卓.gms",
      "play-services-games",

      namedArgs: new Dictionary<string, object>() {
          {"packageIds", new string[] { "extra-google-m2repository" } }
      });

    // This example gets the com.安卓.support.support-v4 library, version 23.1 or greater.
    // notice it is in a different package  than the play-services libraries.

    Google.VersionHandler.InvokeInstanceMethod(
      svcSupport, "DependOn",
      new object[] { "com.安卓.support", "support-v4", "23.1+" },
      namedArgs: new Dictionary<string, object>() {
          {"packageIds", new string[] { "extra-安卓-m2repository" } }
      });

    Google.VersionHandler.InvokeInstanceMethod(
      svcSupport, "DependOn",
            new object[] { "com.hyprmx.mediate", "HyprMediate-SDK", "1.1.0" });

  }

  /// <summary>
  /// Registers the IOS dependencies.
  /// </summary>
  public static void RegisterIOSDependencies() {

    // Setup the resolver using reflection as the module may not be
    // available at compile time.
    Type iosResolver = Google.VersionHandler.FindClass(
        "Google.IOSResolver", "Google.IOSResolver");
    if (iosResolver == null) {
      return;
    }

    // Dependencies for iOS are added by referring to CocoaPods.  The libraries and frameworkds are
    //  and added to the Unity project, so they will automatically be included.
    //
    // This example add the GooglePlayGames pod, version 5.0 or greater, disabling bitcode generation.

    Google.VersionHandler.InvokeStaticMethod(
      iosResolver, "AddPod",
      new object[] { "GooglePlayGames" },
      namedArgs: new Dictionary<string, object>() {
          { "version", "5.0+" },
          { "bitcodeEnabled", false },
      });
  }

  // Handle delayed loading of the dependency resolvers.
  private static void OnPostprocessAllAssets(
      string[] importedAssets, string[] deletedAssets,
      string[] movedAssets, string[] movedFromPath) {
    foreach (string asset in importedAssets) {
      if (asset.Contains("IOSResolver") ||
        asset.Contains("JarResolver")) {
        RegisterDependencies();
        break;
      }
    }
  }
}

然而，我在Unity中遇到了一个错误：Assets/Plugins/MyDependencies.cs(96,5): error CS0103: The nameGoogle'在当前上下文中不存在`

有什么想法可以让我更新代码，让谷歌能够解析，这样我就可以运行这个类了？看起来他们提供了dll来帮助解决这个问题，但我不知道如何让他们解决。我试图使用using dll1等来引用它们，但似乎没有找到它们
