set FCM high-priority when using firebase-admin

Question

I have the following code which uses firebase-admin to send messages using Firebase cloud messaging

Message message = null;
message = Message.builder().putData("From", fromTel).putData("To", toTel).putData("Text", text)
            .setToken(registrationToken).build();

String response = null;
try {
    response = FirebaseMessaging.getInstance().sendAsync(message).get();
    responseEntity = new ResponseEntity<String>(HttpStatus.ACCEPTED);
} catch (InterruptedException | ExecutionException e) {
    e.printStackTrace();
}
System.out.println("Successfully sent message: " + response);

The above code works fine. But I need to send "high-priority" messages so that the device can receive them while in doze mode.

How can I make the messages "high-priority"?

Answer 1

For sending to Android devices, when building the message, set its AndroidConfig to a value that has Priority.HIGH:

AndroidConfig config = AndroidConfig.builder()
        .setPriority(AndroidConfig.Priority.HIGH).build();

Message message = null;
message = Message.builder()
        .putData("From", fromTel).putData("To", toTel).putData("Text", text)
        .setAndroidConfig(config) // <= ADDED
        .setToken(registrationToken).build();

For additional details, see the example in the documentation.

When sending to Apple devices, use setApnsConfig(), as explained in the documentation.

Thanks for the answer. The high priority is working, but still if I don't touch my phone for a while, and when I send it a Firebase cloud message it takes the phone a very long time to process it. Am I supposed to using Firebase Job Dispatcher in order for my app to work when the phone is sleep? When the phone is awake the phone processes everything within a few seconds – Proudlove

With a high-priority message, I would expect the message receipt delay to be about the same for an awake and sleeping device. What model phone are you testing with? I have seen reports of different behaviors depending on device model. – Sympathize

It's running on the Moto G4 Play – Proudlove

You could try sending notifications from the Firebase Console. The are high-priority by default and will give you an idea of receipt delay for different device states. – Sympathize

I did some debugging, I now print something on the app screen with a timestamp when a Firebase message is received. The message does appear, but it does not continue to do rest of the job. It's supposed to create a new instance of a class, then create a new thread and download an image. This is the class that it will use once a Firebase message is received pastebin.com/RUrZwb4L I'm not sure if I'm doing something wrong on my side – Proudlove

SO is not an efficient forum for debugging. I would expect an awakened device to remain awake for at least 10 seconds. Maybe the image download is taking longer than expected. You're making good use of log-statements. Add more if needed to determine if the device is going to sleep before the processing is complete. – Sympathize

I will try to figure it out with more debugging, but I think the issue is the phone. I'm going to try it with a different ROM to see what happens – Proudlove

Without an AndroidConfig Builder

function sendFCM(token, from, to, text) {
    var admin = require("firebase-admin");
    var data = {
        from: from,
        to: to,
        text: text
    };
    let message = {       
        data: data,
        token: token,
        android: {
            priority: "high",  // Here goes priority
            ttl: 10 * 60 * 1000, // Time to live
        }
    };
    admin.messaging()
        .send(message)
        .then((response) => {
            // Do something with response
        }).catch((error) => {
            console.log(error);
        });
}

public async Task send_PushNotification(FirebaseAdmin.Messaging.Message MESSAGE)
    {   
        var defaultApp = FirebaseApp.Create(new AppOptions()
        {
            Credential = GoogleCredential.FromFile(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "key_FB.json")),
        });

        var message = MESSAGE;
        message.Token = FB_TOKEN;
        message.Android = new AndroidConfig();
        message.Android.Priority = Priority.High;
        message.Android.TimeToLive = new TimeSpan(0,0,5);
       
        var messaging = FirebaseMessaging.DefaultInstance;
        var result = await messaging.SendAsync(message);
        Console.WriteLine(result);
    }

Wunderlich

Please provide more explanation to your answer, e.g. putting it in the context of a question. – Curve

This may help somebody.

public String sendFcmNotification(PushNotificationRequestDto notifyRequest) throws FirebaseMessagingException {
        String registrationToken = notifyRequest.getToken();

        AndroidConfig config = AndroidConfig.builder()
                .setPriority(AndroidConfig.Priority.HIGH).build();

        Notification notification = Notification.builder()
                .setTitle(notifyRequest.getTitle())
                .setBody(notifyRequest.getBody())
                .build();

        Message message = Message.builder()
                .setNotification(notification)
//                .putData("foo", "bar")
                .setAndroidConfig(config)
                .setToken(registrationToken)
                .build();


        return FirebaseMessaging.getInstance().send(message);
    }

Worked nicely! Thanks. – Towhee
