Huawei Push Kit, payload sent does trigger onMessageReceive

Based on the documentation I follow here documentation
the payload I had sent does not trigger onMessageReceived method for me to parse it instead it automatically trigger notification by the Huawei notification center.
this is a sample payload I've sent, and I've already include foreground_show and set it to false as mention in the web:
{
"validate_only":false,
"message": {
"notification": {
"title": "message title",
"body": "message body"
},
"android": {
"notification": {
"foreground_show": false,
"click_action": {
"type": 3
}
}
},
"data":"{'param2':'value1','param3':'value2'}",
"token": [
"ABW18Q4Rw5CAB68f9yS_1f859k0s-t3G1aIZheq5l6TedFj_Iold4I6M2EK-pwPTzt6HXxL_"
]
}
}
the result was, it does not trigger onMessageReceive function but it automatically creates the notification on the device.
but if I remove notification and android from the payload and only sending data it successfully trigger onMessageReceive :
{
"validate_only": false,
"message": {
"data": "{'param1':'value1','param2':'value2'}",
"token": [
"ABW18Q4Rw5CAB68f9yS_1f859k0s-t3G1aIZheq5l6TedFj_Iold4I6M2EK-pwPTzt6HXxL_"
]
}
}
this is the class where I already override the onMessageReceived:
class CustomPushService : HmsMessageService() {
private val TAG = "PushTokenLog"
override fun onNewToken(token: String?, bundle: Bundle?) {
super.onNewToken(token, bundle)
Log.d(TAG, "receive token:$token")
}
override fun onMessageReceived(remoteMessage: RemoteMessage?) {
Log.d(TAG, "onMessageReceived")
Log.d(TAG, "onMessageReceived:title:${remoteMessage?.notification?.title}")
super.onMessageReceived(remoteMessage)
}
}
I already include foreground_show: false and it wont trigger onMessageReceived unless if I only sending data in the payload then it will trigger onMessageReceived.
so is it not possible to send full payload as shown in the first payload and trigger onMessageReceived so that I can process the payload? and please let me know if my method wrong

In your request payload, you've set "message.android.notification.foreground_show” to “false”, which means your app is in the foreground and you will get the message data in the function onMessageReceived. Please double-check if your app is in the foreground.
Your device EMUI must be greater than EMUI 9.1.0, and Push SDK version must be greater than 4.0.
The class CustomPushService definition is good.
I used your 1st sample payload to test on my project. It worked very well. Please see below screenshot. The process entered into the function onMessageReceived as below.
Please refer to https://developer.huawei.com/consumer/en/doc/development/HMSCore-Guides/android-server-dev-0000001050040110 and https://developer.huawei.com/consumer/en/doc/development/HMSCore-References/https-send-api-0000001050986197 for more information.
If you still have issues, please share logcat logs with me.

Firebase push notifications is not triggering onMessageReceive on Android when the app is closed

When I don't send the notification object in the JSON request to the Firebase API, the onMessageReceive is triggered normally and my notifications work as intended, but, when I use the notification or the android object in the JSON that I send as params the onMessageReceive is not triggered when the app is in background.
I've been trying to debug this but I can't figure it out.
I have a simple class in my server that user Firebase API to send the push notifications.
In the params that I send to the server, I'm sending the following attributes.
"apns": {
"title": title.nil? ? "Testing notification" : title,
"body": body.nil? ? "This is a test push notification, liking it?" : body,
"mutable_content": true,
"sound": sound.nil? ? "enabled" : sound
},
"android": {
"title": title.nil? ? "Testing notification" : title,
"body": body.nil? ? "This is a test push notification, liking it?" : body,
"sound": sound.nil? ? "enabled" : sound
},
or the following for cross plataforms.
"notification": {
"title": title.nil? ? "Testing notification" : title,
"body": body.nil? ? "This is a test push notification, liking it?" : body,
"mutable_content": true,
"sound": sound.nil? ? "enabled" : sound
},
This configuration is suggested by google in the following official documentation
Firebase Documentation
The only way it actually works is when I DO NOT SEND the notification or android object and generate the notification with the data I send in the data attribute of the JSON object sended to the Firebase API
params = {
"#{key}": to,
# "apns": {
# "title": title.nil? ? "Testing notification" : title,
# "body": body.nil? ? "This is a test push notification, liking it?" : body,
# "mutable_content": true,
# "sound": sound.nil? ? "enabled" : sound
# },
# "android": {
# "title": title.nil? ? "Testing notification" : title,
# "body": body.nil? ? "This is a test push notification, liking it?" : body,
# "sound": sound.nil? ? "enabled" : sound
# },
"data": {
"title": title,
"body": body
}
}.to_json
The notifications sent through the Firebase console don't work either.
¿Any ideas?

Use Below Xml Code in andorid manifest
<service
android:name=".services.MyFirebaseMessagingService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
Create MyFirebaseMessaginfService Class to recive Firebase Notification When App is close.
public class MyFirebaseMessagingService extends FirebaseMessagingService {
LocalBroadcastManager broadcaster;
#Override
public void onCreate() {
broadcaster = LocalBroadcastManager.getInstance(this);
}
#Override
public void onNewToken(#NonNull String token) {
Log.d(TAG, "Refreshed token: " + token);
Const.FireBaseTokenID=token;
Log.e(TAG, "onComplete:Service "+Const.FireBaseTokenID );
}
public MyFirebaseMessagingService() {
getFireBaseID();
}
public static void getFireBaseID() {
FirebaseInstanceId.getInstance().getInstanceId()
.addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
#Override
public void onComplete(#NonNull Task<InstanceIdResult> task) {
if(!task.isSuccessful()){
Log.w(TAG, "getInstance ID Failed "+task.getException() );
return;
}
String token = task.getResult().getToken();
Log.e(TAG, "onComplete:Service Method "+token );
}
});
}
#Override
public void onMessageReceived(#NonNull RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
String call_api=remoteMessage.getData().get("callapi");
String play_id=remoteMessage.getData().get("play_id");
String clue_number=remoteMessage.getData().get("clue_number");
String title=remoteMessage.getData().toString();
Log.e(TAG, "onMessageReceived: callapi "+call_api );
Log.e(TAG, "onMessageReceived: play_id "+play_id );
Log.e(TAG, "onMessageReceived: clue number "+clue_number );
Log.e(TAG, "onMessageReceived: title "+title );
Intent intent= new Intent("remoteMessage");
intent.putExtra("call_api", call_api);
intent.putExtra("play_id", play_id);
intent.putExtra("clue_number", clue_number);
intent.putExtra("title", title);
broadcaster.sendBroadcast(intent);
}
}

You should send with format data, same:
{
"message":{
"token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"data":{
"Nick" : "Mario",
"body" : "great match!",
"Room" : "PortugalVSDenmark"
}
}
}

Notification not receive when Application terminated in android

I use firebase push notification to device token. When app is opening or in foreground I can get notification well. But when app is kill or clear app on current task, I cannot receive notification send.
I have tried on onMessageReceived aleardy at first time work. but now it's not work when killed app.
Code Receive Notification:
class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(p0: RemoteMessage) {
val data = p0!!.data
Log.e("AAAAAAAAAAAAA: ","data
111111111111111111111111111111111111111111111111:" + data["key1"])
}
}
Post Send notification data:
Send to: https://fcm.googleapis.com/fcm/send
Data :
{
"to" : "token key",
"data": {
"key1" : "value1",
"key2" : "value2",
"other_key" : true
}
}
Result, for app is opening, I can receive data well, but when killed I cannot receive data.

If you're sending data to
https://fcm.googleapis.com/fcm/send
you're using the legacy http protocol as you can see here
This is not very clear in documentation.
In this protocol to receive the data message when app is in background or closed you should use this payload:
{
"to" : "token key",
"data": {
"key1" : "value1",
"key2" : "value2",
"other_key" : true
},
"priority" : 10,
"time_to_live" : 60
}
Test first with maximum priority (10) and then downgrade according t your needs. Also adjust time_to_live in seconds according to your needs.

FCM notification title remains "FCM Message"

I'm trying to use the Firebase Cloud Messaging. I send the notifications from a Node.js server to my apps that are registered to the notification system.
My problem is that on Android 5.1 the notification is "FCM Message" even if I setted the title attribute in the nofitification json. It works fine in Android 6.0. I tried to reboot my device as well.
And this is the code I use to send the notification:
function sendNotificationToUser(userToken, message, onSuccess) {
request({
url: 'https://fcm.googleapis.com/fcm/send',
method: 'POST',
headers: {
'Content-Type' :' application/json',
'Authorization': 'key='+API_KEY
},
body: JSON.stringify({
notification: {
"title": 'My App Name',
"body": message,
"sound": 'default'
},
to : userToken
})
}, function(error, response, body) {
if (error) { console.error(error); }
else if (response.statusCode >= 400) {
console.error('HTTP Error: '+response.statusCode+' - '+response.statusMessage);
}
else {
onSuccess();
}
});
}
As you can see the notification title I send is "My App Name" but on device it shows "FCM Message".
What do I have to do?!

You need to pass the title and then receive it in remoteMessage.getNotification().getTitle() , this will catch title and then display in the top or pass complete JSON from web and receive like this
JSONObject jsonObject = new JSONObject(remoteMessage.getData());
Here is the complete method:
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// ...
// TODO(developer): Handle FCM messages here.
// Not getting messages here? See why this may be: https://firebase.google.com/support/faq/#fcm-android-background
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());
}
// 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.
}
Ref link

I found that it is a problem related to onMessageReceived callback.
As you can see on the receive a FCM guide

This is expected. (Tested upto Android 10)
FCM has different behaviours for app status (foreground and background / killed).
You should handle this by the payload you sent from server, according to your use case.
The msg sent from server has to be sent in either "notification" or "data" format, from dashboard or server side api.
Note: From firebase dashobard you can only send "notification" body and not data. In such cases, FCM will directly display the notif without giving a callback to your app.
Server side
Below are sample formats :
Notification Type Format
Note : Android System will by default display the notification in the notification tray and you don't need to display it.
{
"to": "your_token_id",
"notification" : {
"title" : "FCM Notification title!",
"body" : "FCM Notification subtext!",
"content_available" : true,
"priority" : "high"
}
}
Data Format (For receiving callback in app, in foreground and background)
Note : You have to handle callback and display notif on your own.
{
"to": "your_token_id",
"data" : {
"title" : "FCM Notification Title ",
"subtext" : "FCM Notification Sub Title",
"type" : "999",
"priority" : "high"
}
}
Android Client
To handle the payload received in your Android receiver, checl the official guide here
override fun onMessageReceived(remoteMessage: RemoteMessage) {
Log.d(TAG, "From: ${remoteMessage.from}")
// Check if message contains a data payload.
remoteMessage.data.isNotEmpty().let {
Log.d(TAG, "Message data payload: " + remoteMessage.data)
if (/* Check if data needs to be processed by long running job */ true) {
// For long-running tasks (10 seconds or more) use WorkManager.
scheduleJob()
} else {
// Handle message within 10 seconds
handleNow()
}
}
// Check if message contains a notification payload.
remoteMessage.notification?.let {
Log.d(TAG, "Message Notification Body: ${it.body}")
}
// 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.
}
Check the documentation here

This is how i get the title from remote messages:
var title = ""
override fun onMessageReceived(remoteMessage: RemoteMessage) {
if (remoteMessage.notification != null) {
title = remoteMessage.notification!!.title!!
}
}
val notificationBuilder = NotificationCompat.Builder(applicationContext, channelId)
.setContentTitle(title)

How to handle FCM upstream message in Node server?

I am using node-xcs module to create XMPP CCS server in NodeJs, But in that module there is no method to send ACK message which is required to send back to FCM.

do you use fcm-node package for get FCM token . using that we can register device look at my full coding i have use it for send notification to mobile
var FCM = require('fcm-node');
exports.SendNotification = function(msg,title,type,id,user_id,api_token)
{
var fcm = new FCM(constants.serverKey);
var message = {
registration_ids : api_token,
notification: {
title: title,
body:msg
},
data: {
type: type,
id:id,
user_id:user_id
}
};
fcm.send(message, function(err, response){
if (err)
{
console.log("Error for Send Notification",err);
return;
}
else
{
console.log("Successfully sent Notification", response);
return;
}
});
}
and than call this function like this
msg='new notification for you'
title='Hello'
id='34'
user_id='34'
result='api_token'//save this token in database and retrive using user_id
SendNotification(msg,title,'START_APPOINTMENT',id,user_id,result);
