安装应用程序时永远不会调用 FirebaseMessagingService

【中文标题】安装应用程序时永远不会调用 FirebaseMessagingService

【英文标题】：FirebaseMessagingService is never called when app is installed

【问题描述】：

我刚刚将 FCM 添加到我现有的应用程序中，看起来它不是 FirebaseMessagingService，根本没有被调用。

我为此创建了一个 POC，它运行良好。在安装应用时调用 onNewToken 回调，并在应用处于前台时调用 onMessageReceived。

但在我现有的项目中，它似乎不起作用。请注意，我的项目已经支持 firebase 远程配置

google-services.json 文件已被下载并放在 app 目录下。

androidManifest.xml

<service
        android:name=".MyFirebaseMessaging"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

MyFirebaseMessaging.java

public class MyFirebaseMessaging extends FirebaseMessagingService 
private final String TAG = MyFirebaseMessaging.class.getSimpleName();
public final static String channel1ID = "channel1ID";
public final static String channel1Name = "channel1Name";

@Override
public void onMessageReceived(RemoteMessage remoteMessage) 
    Log.i(TAG, "<<notification>> onMessageReceived");
    if (remoteMessage == null) 
        return;
    
    if (remoteMessage.getData() != null && remoteMessage.getData().size() > 0) 
        Map<String, String> data = remoteMessage.getData();
        String body = data.get("body");
        String title = data.get("title");
        generateNotification(title, body);
     else if(remoteMessage.getNotification() != null) 
        RemoteMessage.Notification notification = remoteMessage.getNotification();
        String title = notification.getTitle();
        String body = notification.getBody();
        generateNotification(title, body);
    


private void generateNotification(String title, String body) 
    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) 
        NotificationChannel channel1 = new NotificationChannel(channel1ID, channel1Name,
                NotificationManager.IMPORTANCE_DEFAULT);

        notificationManager.createNotificationChannel(channel1);
    

    Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.my_large_icon);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channel1ID)
            .setSmallIcon(R.drawable.my_icon)
            .setContentTitle(title)
            .setContentText(body)
            .setPriority(NotificationCompat.PRIORITY_DEFAULT)
            .setLargeIcon(bitmap)
            .setStyle(new NotificationCompat.BigPictureStyle().bigPicture(bitmap).bigLargeIcon(null));

    notificationManager.notify(0, builder.build());



@Override
public void onNewToken(String s) 
    super.onNewToken(s);
    Log.i(TAG, "<<notification>> onNewToken: " + s);

build.gradle - 应用程序

dependencies 
   ...
  implementation 'com.google.firebase:firebase-core:17.0.0'
  implementation 'com.google.firebase:firebase-messaging:19.0.1'
  ...

apply plugin: 'com.google.gms.google-services'

build.gradle - 项目

 dependencies 
   ...
   classpath 'com.google.gms:google-services:4.2.0'
   ...
 

【问题讨论】：

您可以尝试使用降级的消息吗？比如'com.google.firebase:firebase-messaging:17.1.0'

你使用 Firebase 控制台发送消息吗？

@JolsonDaCosta 我使用了 Firebase 控制台和邮递员来发送数据负载。两个 r 都不起作用

@majuran 会尝试。但它在我的 poc 项目中运行良好

【参考方案1】：

你能试试这些版本吗？因为在我的应用中它运行良好。

implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-messaging:17.6.0'

【参考方案2】：

发现问题。问题是我的项目正在使用已弃用的 FirebaseInstanceIdService。从我的清单文件中删除它们有效

<receiver
        android:name="com.google.firebase.iid.FirebaseInstanceIdInternalReceiver"
        tools:node="remove" />
    <receiver
        android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver"
        tools:node="remove" />

    <service
        android:name="com.google.firebase.iid.FirebaseInstanceIdService"
        tools:node="remove" />
