android - 我在 ios 上收到推送通知，但在 Android 上没有

问题描述

我需要有关 android 平台上 xamarin.forms 项目通知的帮助。

OnTokenRefresh 方法效果很好。我正确创建了令牌并将其发送到我的服务器，但问题是当我发送推送时它从未进入 OnMessageReceived 方法。在 IOS 中一切正常。

我的 FirebaseInstanceIdService 实施 =>

[Service]
[IntentFilter(new[] { "com.google.firebase.INSTANCE_ID_EVENT" })]
public class MyFirebaseIIDService : FirebaseInstanceIdService
{
    const string TAG = "MyFirebaseIIDService";
    public override void OnTokenRefresh()
    {
        var refreshedToken = FirebaseInstanceId.Instance.Token;
        Log.Debug(TAG, "Refreshed token: " + refreshedToken);
        Helper.Settings.PlatformSNS = refreshedToken;
    }
}

我的 FirebaseMessagingService 实施 =>

[Service]
[IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })]
public class MyFirebaseMessagingService : FirebaseMessagingService
{
    const string TAG = "MyFirebaseMsgService";
    public override void OnMessageReceived(RemoteMessage message)
    {
        base.OnMessageReceived(message);
        Log.Debug(TAG, "-------------------------------ES UN MENSAJE-------------------------------");
        Log.Debug(TAG, "From: " + message.From);
        Log.Debug(TAG, "Notification Message Body: " + message.GetNotification().Body);
        
    }
}

解决了

问题出在（或者我认为是）包名称中。旧 => com.mycompany.Company。新 => com.mycompany.company。

使用新软件包，一切正常。
