Question

我无法从FirebaseMessagingService实例中读取日志。我没有看到任何日志条目打印到LogCat。

断点也不起作用。 putExtra来电不会触发 - 我的MainActivity中的额外内容始终为null。

这种行为可能是什么原因？

感觉就像以某种方式调用默认的超类FirebaseMessagingService实例。我的自定义代码似乎完全被忽略了。

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMsgService";

    /**
     * Called when message is received.
     *
     * @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
     */
    // [START receive_message]
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // [START_EXCLUDE]
        // There are two types of messages data messages and notification messages. Data messages are handled
        // here in onMessageReceived whether the app is in the foreground or background. Data messages are the type
        // traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app
        // is in the foreground. When the app is in the background an automatically generated notification is displayed.
        // When the user taps on the notification they are returned to the app. Messages containing both notification
        // and data payloads are treated as notification messages. The Firebase console always sends notification
        // messages. For more see: https://firebase.google.com/docs/cloud-messaging/concept-options
        // [END_EXCLUDE]

        // TODO(developer): Handle FCM messages here.
        Log.d(TAG, "From: " + remoteMessage.getFrom());

        // Check if message contains a data payload.
        if (remoteMessage.getData().size() > 0) {
            Log.d(TAG, "Message data payload: " + remoteMessage.getData());

            if (/* Check if data needs to be processed by long running job */ true) {
                // For long-running tasks (10 seconds or more) use Firebase Job Dispatcher.
                scheduleJob();
            } else {
                // Handle message within 10 seconds
                handleNow();
            }

        }

        // Check if message contains a notification payload.
        if (remoteMessage.getNotification() != null) {
            Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
        }

        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated. See sendNotification method below.


        Log.i(TAG, "onNewIntent send notification");
        sendNotification(remoteMessage.getNotification().getBody());
    }
    // [END receive_message]

    /**

     */
    private void scheduleJob() {
        // [START dispatch_job]
        FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(this));
        Job myJob = dispatcher.newJobBuilder()
                .setService(MyJobService.class)
                .setTag("my-job-tag")
                .build();
        dispatcher.schedule(myJob);
        // [END dispatch_job]
    }

    private void sendNotification(String messageBody) {
        Log.i(TAG, "onNewIntent");

        Intent intent = new Intent().setClass(getApplicationContext(), MainActivity.class);
        intent.putExtra("fcm", "test");
        intent.putExtra("notification", true);
        intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
        String uniqueID = UUID.randomUUID().toString();
        intent.setAction(uniqueID);

        PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0 /* Request code */, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
//                .setSmallIcon(R.drawable.ic_stat_ic_notification)
                .setContentTitle("FCM Message")

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());

        MainActivity mainActivity = AppDelegate.shared().mainActivity;
        if (mainActivity != null) {
            NotificationsViewmodel notificationsViewmodel = mainActivity.notificationsViewmodel;
            if (notificationsViewmodel != null) {
                notificationsViewmodel.actionGetNotifications();
            }
        }
    }
}

没有日志（无论我在此窗口中尝试选择什么）：
