Xamarin窗体- Android -远程推送通知- hub.Register()；版本中的异常在调试中构建良好
Xamarin窗体- Android -远程推送通知- hub.Register()；版本中的异常在调试中构建良好
提问于 2020-12-21 20:44:48
因此，在这方面的工作让我想起了为什么我绝对不喜欢远程推送通知。Xamarin窗体解决方案，特别是试图让远程推送通知在一个临时分布式.apk文件中工作。
以下是相关代码：
安卓原生项目中的FireBaseService：
using Android.App;
using Android.Content;
using Android.Util;
using AndroidX.Core.App;
using Firebase.Messaging;
using Newtonsoft.Json;
using Mobile.Client.Configuration;
using System;
using System.Linq;
using WindowsAzure.Messaging;
using Xamarin.Forms;
namespace Mobile.Client.Droid.Notifications
{
[Service]
[IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })]
[IntentFilter(new[] { "com.google.firebase.INSTANCE_ID_EVENT" })]
public class FirebaseService : FirebaseMessagingService
{
const string TAG = "FirebaseService";
public override void OnMessageReceived(RemoteMessage message)
{
Log.Debug(TAG, "From: " + message.From);
if (message.GetNotification() != null)
{
//These is how most messages will be received
Log.Debug(TAG, "Notification Message Body: " + message.GetNotification().Body);
SendNotification(message.GetNotification().Body);
}
else
{
//Only used for debugging payloads sent from the Azure portal
SendNotification(message.Data.Values.First());
}
}
public override async void OnNewToken(string token)
{
Log.Info(TAG, $"Registration Token: {token}");
App.Current.Properties["NotificationToken"] = token;
await App.Current.SavePropertiesAsync();
SendRegistrationToServer(token);
}
private void SendNotification(string messageBody)
{
var intent = new Intent(this, typeof(MainActivity));
intent.AddFlags(ActivityFlags.ClearTop);
var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.UpdateCurrent);
var notificationChannelName = AppSettingsManager.Settings["NotificationChannelName"];
var notificationBuilder = new NotificationCompat.Builder(this, notificationChannelName);
notificationBuilder.SetContentTitle("Notification")
.SetSmallIcon(Resource.Drawable.nndc_logo)
.SetContentText(messageBody)
.SetAutoCancel(true)
.SetAllowSystemGeneratedContextualActions(true)
.SetShowWhen(false)
.SetContentIntent(pendingIntent);
var notificationManager = NotificationManager.FromContext(this);
notificationManager.Notify(0, notificationBuilder.Build());
MessagingCenter.Send(App.Current, "NotificationRecieved");
}
private void SendRegistrationToServer(string token)
{
try
{
var notificationHubName = AppSettingsManager.Settings["NotificationHubName"];
var listenConnectionString = AppSettingsManager.Settings["ListenConnectionString"];
var subscriptionTags = AppSettingsManager.Settings["SubscriptionTags"]?.Split(",");
var fCMTemplateBody = AppSettingsManager.Settings["FCMTemplateBody"];
NotificationHub hub = new NotificationHub(notificationHubName, listenConnectionString, this);
Log.Info(TAG, $"Created hub object: {hub.NotificationHubPath}");
// register device with Azure Notification Hub using the token from FCM
Registration registration = hub.Register(token, subscriptionTags);
Log.Info(TAG, $"Registered token and tags: {registration.PNSHandle}");
// subscribe to the SubscriptionTags list with a simple template.
string pnsHandle = registration.PNSHandle;
Log.Info(TAG, $"PNS Handle: {pnsHandle}");
TemplateRegistration templateReg = hub.RegisterTemplate(pnsHandle, "defaultTemplate", fCMTemplateBody, subscriptionTags);
Log.Info(TAG, $"Registered template: {templateReg.NotificationHubPath}");
}
catch (Exception e)
{
Log.Info(TAG, $"PNS REGISTRATION EXCEPTION: {JsonConvert.SerializeObject(e)}");
//Log.Error("DEBUG", $"Error registering device: {e.Message}");
}
}
}
}Android宣言：

</manifest>不管怎么说，正如标题所说，这在调试中很好，它注册没有问题，并发送推送通知从天蓝色绝对罚款。据我所知，FCM键对于沙箱或生产是一样的，所以我不认为是那样的，但是如果我错了，请随时纠正我。
如果我在发行版中运行此命令，或者将其安装为apk文件，则会得到以下错误：

我也在此链接上针对github上的回购提出了这个问题。他们建议在Pro卫兵或r8周围发消息。实际上，我没有这些设置，但是由于我知道Xamarin和VS有时会做自己的事情，所以我设置了r8收缩器，现在当我运行它时，我得到了下面的错误，它看起来更具有描述性，因为它显示了一个潜在的400个错误。

通知中心客户端
我建议使用Microsoft.Azure.NotificationHubs NuGet软件包 with NotificationHubClient.CreateFcmNativeRegistrationAsync向通知集线器注册。
下面是我在我的开源应用程序GitTrends：Android.cs#L87-L98中注册的代码
var hubClient = NotificationHubClient.CreateClientFromConnectionString("Your Notification Hub Connection String", "Your Notification Hub Name");
await hubClient.CreateFcmNativeRegistrationAsync(token);Google服务JSON
我还建议您确保在Android中包含一个google-services.json文件。(这是我在我的GitTrends应用程序中使用的)。
还需要将其作为GoogleServicesJson项添加到Android文件中：
<ItemGroup>
<GoogleServicesJson Include="google-services.json" />
