i have an app where i get certain data like date , time , team 1 and team 2 from sport api , i want to use FCM to show a notification with data every time ( my notifications are for football live games of premier league , so when games start playing , a notification should pop up in the user app ), is it possible to send data from api to my app via FCM to show a notification , i ve read a little bit about FCM HTTP V1 , but i'm still not sure wether it does the job or not , any suggestions guys , thank you .
You can send JSON that target a specific Topic to all user that subscribe to that Topic.
You can subscribe the user in the that topic by calling this
FirebaseMessaging.getInstance().subscribeToTopic("your_topic");
Once subscribe you can send this JSON to the API https://fcm.googleapis.com/fcm/send
{
"to":"/topics/your_topic",
"notification": {
"title": "Title Message"
"body": "Body Message"
},
"data": {
"time": "your time"
"date": "your date"
"home_team": "your home team"
"away_team": "your away team"
}
together with your headers "Content-Type", "application/json" and "Authorization", "key=your_FCM_legacy_server_key"
it's up to you on how you handle that "data" on your NotificationService
this how you handle the data in this part of JSON
"data": {
"time": "your time"
"date": "your date"
"home_team": "your home team"
"away_team": "your away team"
}
handle it like this
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Map<String, String> data = remoteMessage.getData();
String time= data.get("time");
String date= data.get("date");
String home_team= data.get("home_team");
String home_away= data.get("home_away");
String body = remoteMessage.getNotification().getBody(); //retrieve the notification body
String title = remoteMessage.getNotification().getTitle(); //retrieve the notification title
}

I am trying to display a notification when the fcm message received and the APP is in the background. I tried different flavors of notifications but not luck. The notification won't show
Here is the code
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(GlobalVar.TAG, "From: " + remoteMessage.getFrom());
super.onMessageReceived(remoteMessage);
String channelId = getString(R.string.notification_channel_id);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(remoteMessage.getNotification().getTitle())
.setContentText(remoteMessage.getNotification().getBody()).setAutoCancel(true);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(0, builder.build());
}
I know this is getting called because I get the log.
If the app is in the background then FCM displays notifications. It is the above code that is not displaying it when app is in foreground
Any suggestions?
PS: I created the channel in the Application class
I don't get errors in the log cat. I am also setting all the notifications settings as per code below. Please note my device receive and display notifications already from FCM when it is in background. But when it is in foreground and "I" handle the display of notification then it does not work
Hopefully your server is sending you notification in data key.
Here as I saw your code, You are getting notification data using remoteMessage.getNotification()
Now you have to make changes in your server side script that they send in data key as follow (You can test temporary before changing server code):
{
"to" : "YOUR_FCM_TOKEN_WILL_BE_HERE",
"collapse_key" : "type_a",
"data" : {
"body" : "Body of Your Notification in Data",
"title": "Title of Your Notification in Title",
"key_1" : "Value for key_1",
"key_2" : "Value for key_2"
}
}
and after that you can receive like this:
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
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());
}
}
To know more about it:
Hope you will get help in this. Do let me know if you get any problem.
If you're not using your own server, then you can't achieve this. You need to use your own server to modify the JSON format from this:
{
"to" : "YOUR_FCM_TOKEN_WILL_BE_HERE",
"collapse_key" : "type_a",
"notification" : {
"body" : "Body of Your Notification in Data",
"title": "Title of Your Notification in Title",
"key_1" : "Value for key_1",
"key_2" : "Value for key_2"
}
}
to:
{
"to" : "YOUR_FCM_TOKEN_WILL_BE_HERE",
"collapse_key" : "type_a",
"data" : {
"body" : "Body of Your Notification in Data",
"title": "Title of Your Notification in Title",
"key_1" : "Value for key_1",
"key_2" : "Value for key_2"
}
}
when your server will modify "notification" tag with "data" then only you can recieve notification in background.
Let me go straight to the point, with Firebase Cloud Messaging and Android Oreo there have been some major changes when it comes to using their APIs.
I have entered my Firebase Server Api Key in the PubNub Console, push notification works absolutely fine on the Firebase console, but when publishing notification with PubNub, remoteMessage.toString gives => com.google.firebase.messaging.RemoteMessage#ffe9xxx in the OnMessageReceived function.
I am publishing something like this
JsonObject payload = new JsonObject();
JsonObject androidData = new JsonObject();
androidData.addProperty("contentText","test content");
androidData.addProperty("contentTitle","Title");
JsonObject notification = new JsonObject();
notification.add("notification",androidData);
JsonObject data = new JsonObject();
data.add("data", notification);
payload.add("pn_gcm", data);
in
PubNubObject.publish()
.message(payload)
etc..
Any idea why is this happening?
Thank you in advance.
Code on the receiving end
There is a class which extends FirebaseMessagingService, codes for OnMessageReceived function:
if (remoteMessage.getNotification() != null) {
//for testing firebase notification
Log.d(TAG, "Message Notification
Body:"+remoteMessage.getNotification().getBody());
} else {
//for anything else, I wanted to see what was coming from the server
//this is where I am getting the message when using PubNub notification
Log.d(TAG, "onMessageReceived: remoteMessage to
str:"+remoteMessage.toString() );
}
Android getData vs getNotification API
You are nesting the notification key/value inside of the data key and just need to use the API, remoteMessage.getData() instead of remoteMessage.getNotification().
If notification key was at the top level, it would work. See Android docs here.
Instead of this:
{
"pn_gcm": {
"data": {
"notification": {
"contentText": "test content",
"contentTitle": "Title"
}
}
}
}
This if switing to remoteMessage.getData():
{
"pn_gcm": {
"data": {
"contentText": "test content",
"contentTitle": "Title"
}
}
}
Or this if sticking with remoteMessage.getNotification():
{
"pn_gcm": {
"notification": {
"contentText": "test content",
"contentTitle": "Title"
}
}
}
}
PubNub basically just looks for the pn_gcm in the message payload when it is published and grabs whatever is inside of it and passes that directly to Google's FCM service for the devices that are registered (with PubNub) for that channel to receive GCM (FCM).
If the data is not formatted properly we would receive an error back from FCM which should be reported on the channel's -pndebug channel (assuming pn_debug:true was included in the published message payload).
For full details on troubleshooting FCM (GCM) or APONS issues with PubNub, please review How can I troubleshoot my push notification issues?
I'm trying to implement FCM notification in my app. I have read FCM data message type will receive notification even when app is in background so am trying to implementing that in onMessageRecieved method am getting unexpected response like this:
{title =2, message={"Status":"UNASSIGNED","CompanyName":"gd","LastModifiedDateTime":"2017-04-25 18:59:41","IsPartRequired":false,"ProblemCategory":"CONFIGURATION","IsGeneralClaim":false,"RegistrationID":1057,"IncidentCode":"INS\/2017\/04\/25-0010","StatusID":0,"CreatedDateTime":"2017-04-25 18:59:41","IsInstallationCall":false}}
Don't know how to parse this get separate value from title and message let me post my firebase message code:
public class FireBaseMessage extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Map<String,String> data = remoteMessage.getData();
Log.d(TAG, "From: " + data.toString());
//
}
}
In this log message am getting response like that how to get value from that is try like:
int title=data.get("title");
getting null pointer as this is not in valid format. In my server side i have am trying to post json format like this:
{
"to":"es_OToDkj00:APA91bFqxbVMAaXy5fPtDbNVAkIwyVrPCmfGci2otHZPvdRoXPv-oDdjgtLR92Nqe8w6f57nCVceLbc3_zBWsInG9g1Pfdp3LvsMKyuaiYps0L1y3tn0N0XbzGseEI6jyiqs1r-sT9lb",
"data":{
"message":{
"RegistrationID":1057,
"IncidentCode":"INS/2017/04/25-0010",
"CompanyName":"ABM INFOTECH",
"StatusID":5,
"Status":"ASSIGNED",
"CreatedDateTime":"2017-04-25T12:03:45",
"LastModifiedDateTime":"2017-04-25T18:59:41",
"ProblemCategory":"CONFIGURATION",
"IsPartRequired":false,
"IsInstallationCall":false,
"IsGeneralClaim":false
},
"title ":"1"
}
Don't know where I'm making a mistake. Can anyone help me? Thanks in advance!
To get the Title: from message payload
use:
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
// Check if message contains a data payload.
//In case when notification was send in "notification" parameter we need to check wheather data is null or not.
if (remoteMessage.getData()!=null && remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
String title = remoteMessage.getData().get("title").toString();
}
}
EDIT
check if your remoteMessage contain the specific key:
if (remoteMessage.getData()!=null){
for (Map.Entry<String, String> entry : remoteMessage.getData().entrySet()) {
String key = entry.getKey();
String value = entry.getValue();
Log.d(TAG, "key, " + key + " value " + value);
}}
There are two types of FCM messages:
1) Notification Messages
2) Data Messages
Notification Message Structure:
{
"message":{
"token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification":{
"title":"Portugal vs. Denmark",
"body":"great match!"
}
}
}
In order to get data from the notification payload/messages:
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message From " + remoteMessage.getFrom()); //sender ID
Log.d(TAG, "Notification Title " + remoteMessage.getNotification().getTitle()); //notification title
Log.d(TAG, "Notification Body " + remoteMessage.getNotification().getBody()); //notification body
}
}
Data Message Structure:
{
"message":{
"token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"data":{
"Nick" : "Mario",
"body" : "great match!",
"Room" : "PortugalVSDenmark"
}
}
}
In order to get data from the data payload/messages:
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Data: " + remoteMessage.getData()); //Whole data
Log.d(TAG, "Key Data : " + remoteMessage.getData().get("key").toString()); //Get specific key data
}
}
You have an extra space character in your "title" parameter:
"title ":"1"
It's hard to see since it's just a space. It should be:
"title":"1"
The reason you're note getting any value is because technically, the key being sent is "title " (with a space), while in your client code, you're only using "title" (without a space).
You should be able to receive it correctly after you remove the extra space.
After many search I have found this answer, it working perfect
To make firebase library to call your onMessageReceived() in the following cases
App in foreground
App in background
App has been killed
you must not put JSON key 'notification' in your request to firebase API but instead use 'data', see below.
The following message will not call your onMessageReceived() when your app is in the background or killed, and you can't customize your notification.
{
"to": "/topics/journal",
"notification": {
"title" : "title",
"text": "data!",
"icon": "ic_notification"
}
}
but instead using this will work
{
"to": "/topics/dev_journal",
"data": {
"text":"text",
"title":"",
"line1":"Journal",
"line2":"刊物"
}
}
Basically, the message is sent in the argument RemoteMessage along with your data object as Map, then you can manage the notification in onMessageReceived as in the snippet here
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Map<String, String> data = remoteMessage.getData();
//you can get your text message here.
String text= data.get("text");
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
// optional, this is to make beautiful icon
.setLargeIcon(BitmapFactory.decodeResource(
getResources(), R.mipmap.ic_launcher))
.setSmallIcon(smallIcon) //mandatory
.......

reference: How to handle notification when app in background in Firebase
I'm using Firebase with an Android app (Auth, Database and Notification).
I'm trying to send notification from an external server (in nodejs) so an user can send a notification to another user.
So the android app memorize a list of UserId (the same ids from Firebase Auth) and then send this list to the nodejs server.
With this list, the server contact the url 'https://fcm.googleapis.com/fcm/send', but Firebase returns me a InvalidRegistration because i'm sending a list of userId and not the list of registration token created by firebase notification.
Should I memorize those tokens or there is a way to send notification with the user id ?
(And when I try with a list of tokens, of course it's working.)
var requestData = {
"registration_ids": userIds, //Problem is here
"data": {
"message": "A message"
}
};
request({
url: "https://fcm.googleapis.com/fcm/send",
method: "POST",
json: true,
headers: {
"Authorization": "key=firebaseKey",
"content-type": "application/json",
},
json: requestData
},
function(err, response, body) {
});
Yes, you can. For this you have to register these user Ids instead of device Id token. Then firebase recognized your user Ids.
#Override
public void onNewToken(#NonNull String token) {
super.onNewToken(token);
Log.d("user_token: ",token);
}
I'm using Amazon SNS to send push notifications to an Android device. If I send the following JSON I can't read the parameters in the data element.
{
"default": "message here",
"GCM": {
"data": {
"message": "This is the message"
}
}
}
I can read the default element but in my broadcastreceiver I can't do this.
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
Log.d("GCM",extras.getString("message");
}
Trying to read the message element causes an error.
If I send directly through GCM I can read all of the parameters that start with data. using the above method with no problem at all.
What am I doing wrong?
You need escape double quotation in GCM value.
{ "default": "message here", "GCM": "{ \"data\": { \"message\": \"This is the message\" } }" }
