AgConnectServicesConfig仅读取AgConnect-Services.json首次

Question

我正在将华为套件（地图，分析，崩溃和推动）集成到我的Xamarin表单应用中，但是有奇怪的行为，AgConnect-Services.JSON仅在我第一次运行该应用程序时才读取，如果我使用该应用程序此代码 var appid = agConnectServicesConfig.fromContext（this）.getString（“ client/app_id”）; > 该值为null。要再次读取配置文件，我也必须卸载该应用程序，即使在发布模式下，也会发生这种情况。 我从华为降低了所有nuget，我使用

public class HmsLazyInputStream : LazyInputStream
    {
        public HmsLazyInputStream(Context context)
            : base(context)
        {
        }

        public override Stream Get(Context context)
        {
            try
            {
                return context.Assets.Open("agconnect-services.json");
            }
            catch (Exception e)
            {
                Log.Error("Hms", $"Failed to get input stream" + e.Message);
                return null;
            }
        }
    }

[ContentProvider(new string[] { "com.test.qa.XamarinCustomProvider" }, InitOrder = 99)]
    public class XamarinCustomProvider : ContentProvider
    {
        public override int Delete(Android.Net.Uri uri, string selection, string[] selectionArgs)
        {
            throw new NotImplementedException();
        }

        public override string GetType(Android.Net.Uri uri)
        {
            throw new NotImplementedException();
        }

        public override Android.Net.Uri Insert(Android.Net.Uri uri, ContentValues values)
        {
            throw new NotImplementedException();
        }

        public override bool OnCreate()
        {
            AGConnectServicesConfig config = AGConnectServicesConfig.FromContext(Context);
            config.OverlayWith(new HmsLazyInputStream(Context));
            return false;
        }

        public override ICursor Query(Android.Net.Uri uri, string[] projection, string selection, string[] selectionArgs, string sortOrder)
        {
            throw new NotImplementedException();
        }

        public override int Update(Android.Net.Uri uri, ContentValues values, string selection, string[] selectionArgs)
        {
            throw new NotImplementedException();
        }
    }

MainActivity.cs中的初始化

if (useHMSService)
           {
               AGConnectCrash.Instance.SetUserId("Anonymous user");
               HiAnalyticsTools.EnableLog();
               var instance = HiAnalytics.GetInstance(this);
               instance.SetAnalyticsEnabled(true);
               instance.SetReportPolicies(new List<ReportPolicy> { ReportPolicy.OnAppLaunchPolicy });

               MapsInitializer.SetApiKey("APIKEY");
               HmsMessaging.GetInstance(this).AutoInitEnabled = true; //Init push notifications

               var appId = AGConnectServicesConfig.FromContext(this).GetString("client/app_id");
               if (!string.IsNullOrWhiteSpace(appId))
               {
                   AlertDialog.Builder alert = new AlertDialog.Builder(this);
                   alert.SetTitle("AppID");
                   alert.SetMessage(appId);

                   Dialog dialog = alert.Create();
                   dialog.Show();
               }

           }

您的问题与使用非官方绑定和包装有关。

这是指向官方Nuget软件包的链接和有关如何使用它的文档。

该示例显示了如何使用MAP KIT软件包和绑定，但是在GitHub站点的示例项目上可以使用其他软件包和绑定。

Here the sample binding project that you can try out.
