Firebase cloud messaging notification not received

问题:

I am having an issue with FireBase Cloud Messaging in which I get the Token from the device and send the notification test through the Google Firebase notification console however, the notification is never logged nor pushed to the android virtual device. The documentation for FCM is almost exactly the code that I have below and little else in the way of what else you would have to do to get push notifications working with firebase. I have gone through all of the setup information (build.gradle additions, Installing google play services, etc...) as specified in the documentation but still do not have messages generating. I do receive a one-time error immediately after pushing the notification that states "I/FA: Tag Manager is not found and thus will not be used" but that is the only data that is output and I did not find anything related to Tag Manager requirements and FCM on the googles. What is wrong with the code that I am not receiving my push notifications to the logcat or the device? Please let me know any further information that would be helpful. Thanks.

NotificationGenie.java

public class NotificationGenie extends FirebaseMessagingService {

private static final String TAG = "Firebase_MSG";

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    // TODO(developer): Handle FCM messages here.
    // If the application is in the foreground handle both data and notification messages here.
    // 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.
    sendNotification(remoteMessage.getNotification().getBody());
    Log.d(TAG, "From: " + remoteMessage.getFrom());
    Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
}

private void sendNotification(String messageBody) {
    Intent intent = new Intent(this, PostLoginActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.tf2spyprofile)
            .setContentTitle("FCM Message")
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

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

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

}

回答1:

You have placed your service outside the application tag. Change bottom to this.

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

</application>

I had the same problem and it is solved by defining enabled, exported to true in my service

  <service
            android:name=".MyFirebaseMessagingService"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT"/>
            </intent-filter>
        </service>

"You must also keep in mind that to receive Messages sent from Firebase Console, App must be in background, not started neither hidden." --- According to @Laurent Russier's comment.

I never got any message from Firebase, until i put my app in the background.

This is true only on usb connection for emulator you get notification in foreground as well

回答4:

Call super.OnMessageReceived() in the Overriden method. This worked for me! Finally!

回答5:

I faced the same issue of Firebase cloud messaging not received by device.

In my case package name defined on Firebase Console Project was diferent than that the one defined on Manifest & Gradle of my Android Project.

As a result I received token correctly but no messages at all.

To sumarize, it's mandatory that Firebase Console package name and Manifest & Gradle matchs.

You must also keep in mind that to receive Messages sent from Firebase Console, App must be in background, not started neither hidden.

回答6:

I had a similar problem, but in my case I was missing the google-services plugin from my Gradle build (I was adding Firebase to an existing project).

I added the following to my root build.gradle:

classpath 'com.google.gms:google-services:3.1.0'

and the following to the end of my app-level build.gradle:

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

I then had to download the google-services.json file from the Firebase Console (having originally imported an existing Google Cloud project) and copy it to my app directory`.

回答7:

I faced the same problem but I had still had some debris in my manifest from the old GCM. When I took the following permission out of my manifest it fixed the error. com.google.android.c2dm.permission.RECEIVE

回答8:

If you have just added FCM to an existing app, onTokenRefresh() will NOT be called. I got it to run by uninstalling the app and installing it again.

You need to Follow Below Manifest Code (must have Service in manifest)

 <?xml version="1.0" encoding="utf-8"?>

回答12:

When you copying your device token, it might copying the space, double check you have copied the correct token

回答13:

I've been working through this entire post and others as well as tutorial videos without being able to solve my problem of not receiving messages, the registration token however worked.

Until then I had only been testing the app on the emulator. After trying it on a physical phone it instantly worked without any prior changes to the project.

回答14:

I had this problem, I checked my code. I tried to fix everything that was mentioned here. lastly the problem was so stupid. My device's Sync was off. that was the only reason I wasn't receiving notifications as expected.

回答15:

maybe it is from the connection I changed the connection from Ethernet to wireless the it worked without doing anything else
