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.

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.

Not receive fcm notification when app is closed

Hello I am trying tyo implement FCM in xamarin forms app.
i Installed Plugin.FirebasePushNotification Plugin
i implement refresh token class
[Service]
[IntentFilter(new[] { "com.google.firebase.INSTANCE_ID_EVENT" })]
public class MyFirebaseIIDService : FirebaseInstanceIdService
{
const string TAG = "MyFirebaseIIDService";
public override void OnTokenRefresh()
{
var refreshedToken = FirebaseInstanceId.Instance.Token;
Log.Debug(TAG, "Refreshed token: " + refreshedToken);
SendRegistrationToServer(refreshedToken);
}
void SendRegistrationToServer(string token)
{
// Add custom implementation, as needed.
}
}
and this class for receive notification but not get notification when app is close
[IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })]
public class MyFirebaseMessagingService : FirebaseMessagingService
{
const string TAG = "MyFirebaseMsgService";
// [START receive_message]
public override void OnMessageReceived(RemoteMessage message)
{
}
}
and i used this payload
{ "to" : "APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx...", "notification"
: {
"body" : "great match!",
"title" : "Portugal vs. Denmark" } }

From Android Official document,FirebaseMessaging has method of subscribeToTopic .
public Task subscribeToTopic (String topic)
Subscribes to topic in the background.
The subscribe operation is persisted and will be retried until successful.
This uses a Firebase Instance ID token to identify the app instance and periodically sends data to the Firebase backend.
Here is a official sample for Android FCM Remote Notifications.After testing this project,If not subscribing notification, notification will not receive when app stopped.
You can have a try.Code as follow when App load:
FirebaseMessaging.Instance.SubscribeToTopic("news");

In my case. I added OneTimeWork with Result.retry and added setBackoffCriteria to 30 seconds to ensure FirebaseMessaging.getInstance().isAutoInitEnabled().
If the result is false, I run it again with FirebaseMessaging.getInstance(). setAutoInitEnabled(true).
Sorry if my english is so bad, because I use Google Translate.

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)

Cannot send push notification via Azure Mobile Service

I have setup a Mobile Service in Azure and connected it to my Android app. Through this app I am calling the Azure API to insert an object into a database table linked to the mobile service.
I have written the script that is executed before it gets inserted. That script is intended to send a push notification to another device.
Now the case is, the object gets inserted into table but no push notification is received. What could be wrong? How can i debug?
Here's my insert script:
function insert(item, user, request) {
var devices = tables.getTable('Devices');
var receiverHandle;
devices.where({userId: item.receiver}).read({
success: populateHandle
});
request.execute({
success: function() {
// Write to the response and then send the notification in the background
request.respond();
console.log(item);
push.gcm.send(item.handle, item, {
success: function(response) {
console.log('Push notification sent: ', response);
}, error: function(error) {
console.log('Error sending push notification: ', error);
}
});
}
});
function populateHandle(results){
receiverHandle = results[0].handle;
}
}
Although logs state successful delivery of push notification. I am not receiving it on my device.
Here is one of the logs:
Push notification sent: { isSuccessful: true, statusCode: 201, body: '', headers: { 'transfer-encoding': 'chunked', 'content-type': 'application/xml; charset=utf-8', server: 'Microsoft-HTTPAPI/2.0', date: 'Sun, 10 Aug 2014 15:01:52 GMT' }, md5: undefined }

Refer to Migrate a Mobile Service to use Notification Hubs.
Microsoft had been upgraded the Mobile Service, to push notifications powered by Notification Hubs. You will not be affected if you created the mobile service before the upgrade.
Base on the response { isSuccessful: true, statusCode: 201, body ... }, it indicate that your Mobile Service is the new version.
If you prefer to send push without Notification Hubs, don't use push.gcm.send, use the following code snippet instead.
var legacyGcm = require('dpush');
legacyGcm.send(your_GCM_APIKEY, regId, item, function (error, response) {
if (!error) {
// success code
} else {
// error handling
}
});
