Firebase云消息传递 - onMessageReceived无法正常工作

时间：2018-02-24 23:00:41

标签： java android firebase firebase-cloud-messaging

我想在我的应用中制作一个简单的通知功能。我关注了this YouTube视频以及这两个Firebase文档网址1和2以及Android Studio中的Firebase工具助手（我说我已连接到Firebase）。出于某种原因，在我的旧应用程序上执行这些步骤和文档（下面发布了代码），它不允许我接收通知。但是，如果我在一个全新的应用程序上执行相同的步骤，它将完美地运行。我在后台，活动和终止状态下测试了同一物理设备和环境中的两个应用程序。每次我创建的新演示应用程序都没有问题，但我想要通知的旧应用程序不起作用。两者均未经过设备ID测试。我甚至没有得到任何错误日志或任何TAG日志。我认为我的一个编译项目是干扰的，不确定究竟是什么，但我可能要看那里。

我还检查了所有这些SO帖子：1 2 3以及更多

PS。我在下面删除了我的包名，我在FireBase上多次检查并且它们匹配，所以我知道这不是问题。但是，我的新演示应用程序的FireBase显示我的应用已连接，但我的旧应用程序的FireBase没有。此外，我之前已经设定了赏金，但仍然遇到同样的问题。

这是我有问题的代码：

Notification.java（它是一个类似文档的服务）

public class Notification extends FirebaseMessagingService {
public Notification() {
}
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    showNotification(remoteMessage.getData().get("message"));

    Log.d("FMC", "Message Notification Body: " + remoteMessage.getNotification().getBody());
}

private void showNotification(String message) {
    Intent i=new Intent(this, SplashScreen.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent=PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder builder=new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentTitle("FCM TITLE").setContentText(message)
            .setSmallIcon(R.drawable.pt_icon)
            .setDefaults(android.app.Notification.DEFAULT_ALL)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager= (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(0,builder.build());
}
}
  

注意我甚至没有登录上面的notification.java。

如果您正在接收设备令牌并且您有服务器api密钥，请使用pushtry 检查您的代码是否正常工作。 如果您的代码中有任何错误，则会出现无效注册， 404错误等错误。 对于FCM的实施，您可以按照本教程 - FCM Tutorial

进行操作

我在build.gradle文件中注意到的另一件事是applicationId "Package Name"中没有任何defaultConfig。 我不确定，但这是包名，并在我们在firebase控制台上创建项目时使用（带包的项目名称）

由于 Android Oreo 新notifications model，因此需要指定频道定义以构建和显示通知，因此很可能未显示您的通知。同样在您的app.gradle中，您的目标是版本26 Android Oreo ，因此您必须以下列方式实现以下代码。

很容易采用。你需要做的就是：

<强> 1。在YourApplicationClass.onCreate（）

中定义通知渠道 
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

            NotificationChannel chan1 = new NotificationChannel(
                YOUR_DESIRED_CHANNEL_ID_STRING,
                YOUR_DESIRED_CHANNEL_LABEL_STRING, 
                NotificationManager.IMPORTANCE_DEFAULT);

            chan1.setDescription(YOUR_DESIRED_CHANNEL_DESC_STRING);//OPTIONAL
            chan1.setLightColor(Color.BLUE);//OPTIONAL     
            chan1.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);//OPTIONAL
            chan1.setShowBadge(true);//OPTIONAL

            getManager().createNotificationChannel(chan1);
        }

<强> 2。用此构造函数替换您的通知构建器 

    NotificationCompat.Builder builder=
new NotificationCompat.Builder(this, YOUR_DESIRED_CHANNEL_ID_STRING);

很高兴知道您可以定义多个具有针对Android Oreo及更高版本的不同属性的频道

答案 2 :(得分：4)

如果你看看这个doc 您似乎没有扩展FirebaseInstanceIdService的服务来管理令牌创建/轮换。 Here是一个示例代码。此类将接收您将推送通知发送到特定设备所需的令牌。

<service
    android:name=".MyFirebaseInstanceIDService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
</service>

修改：

好的，这个错误现在让我烦恼。我看了你的依赖树，我看到你重复了一些。例如，您有三个版本：

compile 'com.android.support:appcompat-v7:25.4.0'

也许您应该将其清除到最新版本，或者将其与工作版本相匹配。您也在使用新的gradle插件，但在大多数情况下，您还没有更新您的依赖关系以使用implementation代替compile，也可以尝试一下？在这里why你应该这样做。

//这有助于在手机重启时在后台启动FCM服务。

答案 4 :(得分：3)

从FCM消息中删除通知有效内容，以便将数据有效负载传递给onMessageReceived方法。

仔细阅读以下链接。

当您的应用在后台时，仅当没有通知有效负载时，数据有效负载才会传递到onMessageReceived方法。 （标记单词）

如果两个有效负载都存在，那么系统会自动处理通知部分（系统托盘），并且您的应用程序会在启动器活动的附加内容中获取数据有效负载（在用户点击通知后）。

为了能够成功地为Android和iOS两个平台提供服务，您可能需要根据客户端的操作系统发送不同的FCM消息。

答案 5 :(得分：3)

希望您了解通知的类型，如需发送通知，您必须使用自定义服务器或邮递员等，有关详细信息，请参阅以下问题的答案：

How to handle notification when app in background in Firebase

无论如何，您必须在FirebaseMessagingService中调用handleIntent（Intent intent）方法才能调用onMessageReceived（）方法。

即使我遇到同样的问题，也可以通过在AndroidManifest.xml中添加完整路径 android：name 服务来解决问题

<service android:name="com.testapp.Notifaction">
     <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

尝试一次＆amp;如果您有任何问题，请告诉我。

由于您尚未从Firebase收到任何日志事件，请检查以下步骤：

  • 转到Firebase项目控制台，输入项目设置并检查包名称是否正确。
  • 再次下载JSON文件并将其复制到app/模块（将项目视角从Android更改为项目）， MAKE SURE文件名 google-services.json
  • 运行您的项目，转到logcat搜索关键字Firebase，如果成功，您将看到消息：
  

I / FirebaseInitProvider：FirebaseApp初始化成功

答案 8 :(得分：2)

让我们一步一步地检查您的所有代码与我的实际项目进行比较，该项目是使用Firebase Messaging服务的最新版本进行生产的：

  • 您对gradle的依赖关系看起来不错，但您只需要implementation "com.google.firebase:firebase-messaging:15.0.2"

  • 您可以尝试将您的课程重命名为不同的课程吗？ Notification名称可能是与自己的Android Notification类的交互。还记得它应该有一个Empty构造函数（但我在你的代码中看到你有它）

将其称为MessagingController，并将其放在<application>内的清单上，如：

   <!--Service to control messaging requests-->
        <service
            android:name=".messaging.controller.MessagingController"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>
    </application>

此外，请不要忘记您需要FirebaseInstanceService的实例，这需要像Official Doc says一样：

  

扩展FirebaseInstanceIdService以处理注册令牌的创建，轮换和更新的服务。这是发送到特定设备或创建设备组所必需的。

<!--Firebase instance service to renew messaging tokens-->
        <service
            android:name=".messaging.service.FirebaseInstanceService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
            </intent-filter>
        </service>
  • 您是否从Firebase控制台发送通知？或使用Firebase Cloud功能？在这两种情况下，您是否引入了正确的令牌？如果您设置超时令牌，Firebase控制台会显示错误，您应该添加如下通知：

enter image description here

  • 好的，此时，您的代码至少应该在日志中接收通知，

  • 如果您需要，可以检查下一个项目是应用程序Skeleton来构建通知系统。也许它对你有帮助：https://github.com/FrangSierra/PushNotificationSkeleton

  • 最后，如果您想查看一些有关如何从服务器发送通知的云功能代码，建议您查看This repository

让应用程序在firebase数据库中侦听一些值，并将其更改为您想要的消息。 我这样做是为了我的应用程序，它的工作就像魅力。

您是否在FCM控制台上注册了您的应用程序？并在您的应用程序中添加了.json文件？

有两种类型的通知数据 1）通知有效载荷 2）数据有效载荷 如果您从通知有效负载平均值的服务器发送数据。有可能没有调用来自FirbaseMessagingService的onMessageRecieved（）查看this link

答案 12 :(得分：1)

这只是一个简单的建议，但几周之前给我造成类似错误的原因是我发送了错误的通知形式。 我发出了无声通知，即使我应该发出响亮的声音。检查服务器如何发送消息。我还搞砸了FCM API期望密钥的顺序。

这是我的工作大声通知代码，由Django Python服务器发送：

def _build_loud_message(not_id, data):
    """Construct loud notifiation message.
    Loud means that this message will show up in the notifications hub
    of the app.
    """
    return {
        'message': {
            'notification': {
                'title': 'New activity',
                'body': 'Hey you have some new activity!'
            },
            'data': {"data": data},
            'apns': {
                'payload': {
                    "notId": not_id,  # notId HAS TO BE FIRST!!!
                    'aps': {
                        'badge': 1,
                        'sound': 'default',
                        'content-available': 1
                    }
                },
                'headers': {
                    'apns-priority': '10',
                    'apns-collapse-id': 'myid-1'
                }
            },
            'android': {
                'priority': "high",
                'data': {
                    "androidData": data
                },
                'notification': {
                    'sound': 'default',
                    'tag': 'mytag-1'
                }
            }
        }
    }

还要密切注意提及dic键的顺序。更改它们可能导致消息无法从FCM成功发送到设备，即使FCM api说它已成功发送。
