onMessageReceived method in FirebaseMessagingService is not called

I'm sending notification using a firebase cloud function. When I'm sending the payload with notification key, notification sends but method not invoked. But with data key, nothing happened.
Here is my code for FirebaseMessagingService
#Override
public void onMessageReceived(RemoteMessage 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());
sendNotification(remoteMessage.getData().get("title"), remoteMessage.getData().get("body"));
if (/* Check if data needs to be processed by long running job */ true) {
// For long-running tasks (10 seconds or more) use Firebase Job Dispatcher.
scheduleJob();
} else {
// Handle message within 10 seconds
handleNow();
}
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
sendNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
}
}
private void sendNotification(String title, String messageBody){
String channelId = getString(R.string.default_notification_channel_id);
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_logo)
.setContentTitle(title)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Since android Oreo notification channel is needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(0 , notificationBuilder.build());
}
Here is my firebase cloud function
exports.sendNotification = functions.database
.ref("/deals/{userId}/{dealId}")
.onCreate((data, context) => {
const dataValue = data.val();
const topic = context.params.userId;
const payload = {
data: {
title: "New deal created",
body: dataValue.user.name + " added a new deal."
},
topic: topic
};
// Send a message to devices subscribed to the provided topic.
return admin
.messaging()
.send(payload)
.then(response => {
// Response is a message ID string.
console.log("Successfully sent message:", response);
})
.catch(error => {
console.log("Error sending message:", error);
});
});
Also I set up a debugpoint on onMessageReceived() but it did not get fired up.

I figured out the problem. The issue is after doing some changes and building the android project we need to subscribe to topic again.

When your app is in background , firebase will not trigger
OnMessageReceived instead it will show a notification alert
+
make sure you have subscribed the correct topic
+
make sure play services are updated on your device.

Save FCM Push Notification as Messages in Fragment

This is my first question. I have connected my domain into firebase. The push notification is working when I update the post in my Wordpress Blog. Ok, thats good for now. But, i want to save all that notification in a Fragment, and can be clicked from there to start an activity for post id. How to save that Notification?
Here is my Firebase Messaging code:
private static int VIBRATION_TIME = 500; // in millisecond
private SharedPref sharedPref;
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
sharedPref = new SharedPref(this);
if (sharedPref.getNotification()) {
// play vibration
if (sharedPref.getVibration()) {
((Vibrator) getSystemService(Context.VIBRATOR_SERVICE)).vibrate(VIBRATION_TIME);
}
RingtoneManager.getRingtone(this, Uri.parse(sharedPref.getRingtone())).play();
if (remoteMessage.getData().size() > 0) {
Map<String, String> data = remoteMessage.getData();
FcmNotif fcmNotif = new FcmNotif();
fcmNotif.setTitle(data.get("title"));
fcmNotif.setContent(data.get("content"));
fcmNotif.setPost_id(Integer.parseInt(data.get("post_id")));
displayNotificationIntent(fcmNotif);
}
}
}
private void displayNotificationIntent(FcmNotif fcmNotif) {
Intent intent = new Intent(this, ActivitySplash.class);
if (fcmNotif.getPost_id() != -1) {
intent = new Intent(this, ActivityPostDetails.class);
Post post = new Post();
post.title = fcmNotif.getTitle();
post.id = fcmNotif.getPost_id();
boolean from_notif = !ActivityMain.active;
intent.putExtra(ActivityPostDetails.EXTRA_OBJC, post);
intent.putExtra(ActivityPostDetails.EXTRA_NOTIF, from_notif);
}
PendingIntent pendingIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentTitle(fcmNotif.getTitle());
builder.setStyle(new NotificationCompat.BigTextStyle().bigText(fcmNotif.getContent()));
builder.setContentText(fcmNotif.getContent());
builder.setSmallIcon(R.drawable.ic_notification);
builder.setDefaults(Notification.DEFAULT_LIGHTS);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
builder.setPriority(Notification.PRIORITY_HIGH);
}
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
int unique_id = (int) System.currentTimeMillis();
notificationManager.notify(unique_id, builder.build());
}
}

yes you can store the your Notification payload in database and create list in fragment and show data from Database and click on any row start activity according to Post ID by getting post id by position

You can save notification message when the notificaton arrived inside
onMessageReceived(RemoteMessage remoteMessage)
method like this
A full example of a notification is like this..
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
/**
* Called when message is received.
*
* #param remoteMessage Object representing the message received from Firebase Cloud Messaging.
*/
// [START receive_message]
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
try {
// [START_EXCLUDE]
// There are two types of messages data messages and notification messages. Data messages are handled
// here in onMessageReceived whether the app is in the foreground or background. Data messages are the type
// traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app
// is in the foreground. When the app is in the background an automatically generated notification is displayed.
// When the user taps on the notification they are returned to the app. Messages containing both notification
// and data payloads are treated as notification messages. The Firebase console always sends notification
// messages. For more see: https://firebase.google.com/docs/cloud-messaging/concept-options
// [END_EXCLUDE]
// TODO(developer): Handle FCM messages here.
Map<String, String> data = remoteMessage.getData();
String value1 = data.get("key_1");
String value2 = data.get("key_2");
String title=data.get("title");
String msg=data.get("body");
Log.d("Backgraound", value1);
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.
sendNotification(title,msg,value1,value2);
}catch (Exception e){
Log.d("Error Line Number",Log.getStackTraceString(e));
}
}
private void sendNotification(String title,String messageBody, String val1,String val2) {
try {
Intent intent = new Intent(this, Notification_activity.class);
//Bundle bundle = getApplicationContext().getExtras();
Bundle basket = new Bundle();
basket.putString("key_1", val1);
basket.putString("key_2", val2);
intent.putExtras(basket);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
String channelId = getString(R.string.default_notification_channel_id);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.spacebar_round)
.setContentTitle(title)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent)
.setColor( getResources().getColor(R.color.colorPrimary))
.setLargeIcon(BitmapFactory.decodeResource(getApplicationContext().getResources(),
R.mipmap.ic_launcher));
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Since android Oreo notification channel is needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}catch (Exception e){
Log.d("Error Line Number",Log.getStackTraceString(e));
}
}
}

Android push notification logs onMessageReceived but not displaying on device

I am sending some push notifications to android from AWS,
the notification process is working registering the device, and I indeed get the test notifications, but only showing on the log, not on notification bar on top of the screen like any other notification would...
public void onMessageReceived(RemoteMessage remoteMessage) {
// ...
// TODO(developer): Handle FCM messages here.
Log.d("mako", "A From: " + remoteMessage.getFrom());
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.d("mako", "B Message data payload: " + remoteMessage.getData());
if (/* Check if data needs to be processed by long-running job */ true) {
// For long-running tasks (10 seconds or more) use Firebase Job Dispatcher.
// scheduleJob();
} else {
// Handle message within 10 seconds
// handleNow();
}
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d("mako", "C 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.
}
So, I send a test notification:
{
"GCM": "{ \"data\": { \"message\": \"test message\" } }"
}
And I can see in my console log the message test:
10-05 14:57:08.827 23062-23296/com.sb.comm D/mako: B Message data payload: {message=test message}
But is not showing on the little pop-up, What is missing to show the actual push notification on the screen?
Cheers

You have to Generate Notification on your device like this
public void onMessageReceived(RemoteMessage remoteMessage) {
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle("App Name")
.setBadgeIconType(R.drawable.ic_notification)
.setLargeIcon(BitmapFactory.decodeResource(
getResources(),R.drawable.ic_notification))
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setContentText(remoteMessage.getData().get("body"));
NotificationManager notificationManager =
(NotificationManager)
getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(141, notificationBuilder.build());
}
Here Notification Builder will get data from your server notification payload and generate a notification on device.

please add these lines of code to show notification on notification bar.
Intent intent = new Intent(this, YourActivity.class);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,
PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder notificationBuilder = new
NotificationCompat.Builder(this, "my_chanel_id");
notificationBuilder.setSmallIcon(R.drawable.ic_launcher_app);
notificationBuilder.setContentTitle("Titlee");
notificationBuilder.setContentText("anyText");
notificationBuilder.setAutoCancel(true);
notificationBuilder.setSound(uri);
notificationBuilder.setContentIntent(resultPendingIntent);
NotificationManager notificationManager = (NotificationManager)
getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
String CHANNEL_ID = "my_channel_01";// The id of the channel.
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = new NotificationChannel("mychanelId",
"hyperlocal", importance);
notificationManager.createNotificationChannel(mChannel);
}
notificationManager.notify(message_id, notificationBuilder.build());

Turns out it was to do with the formatting of the body, it is not as suggested by >>> SNS "JSON message generator"
the body should be in this format:
{
"GCM": "{ \"notification\": { \"text\": \"test message\" } }"
}

Android Push notification Status Icon issue

I am facing issue while using push notification Firebase,
Issue :
App Icon appears white on a marshmallow and above, so I created the white and transparent set of icons, now push notification icons to appear as I needed but only when the app is on the foreground when a user gets a notification and app is closed the icon appears white itself.
My Manifest
<application
android:name="com.xxxx"
android:allowTaskReparenting="true"
android:hardwareAccelerated="true"
android:icon="#drawable/ic_xxxx"
android:label="#string/app_name"
android:largeHeap="true"
android:theme="#style/AppTheme">
Notification Code : when I get push notification
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder;
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.xxxxxx)
.setColor(getResources().getColor(R.color.accent))
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(contentIntent);
} else {
notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(contentIntent);
}
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(count, notificationBuilder.build());
on Message Recieve Code
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
//Displaying data in log
//It is optional
Log.d(TAG, "Notification Message TITLE: " + remoteMessage.getNotification().getTitle());
Log.d(TAG, "Notification Message BODY: " + remoteMessage.getNotification().getBody());
Log.d(TAG, "Notification Message DATA: " + remoteMessage.getData().toString());
//Calling method to generate notification
//remoteMessage.getNotification().getBody()
sendNotification(remoteMessage.getNotification().getTitle(),
remoteMessage.getNotification().getBody(), remoteMessage.getData());
}

There are two types of notification there.
1.) using default params
String title = remoteMessage.getNotification().getTitle();
String body = remoteMessage.getNotification().getBody();
Server Side Code:
{ "data": {
"score": "5x1",
"time": "15:10"
},
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..."
}
This type of implementation only works when the app is open or in background. You will notified message received ( blank notification will appear as you said) but you won't get any data from it.
2.) using map
Map data = remoteMessage.getData();
Server Side Code:
{
"message":{
"token" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification" : {
"body" : "This is an FCM notification message!",
"title" : "FCM Message",
}
}
}
This will receive even after the app closed. It won't produce the blank white notification.

IF its issue with notification icon as white. Try adding this code in manifest
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="#drawable/app_icon" />

Stacked notifications not working on closed app

I get the stacked notifications working if the app is opened but not when the app is closed. If the app is closed the icon is incorrect and the notifications are not stacked?
Here is my code:
notification = new NotificationCompat.Builder(this);
notification.setContentTitle(notifyFromName);
notification.setContentText(notifyMsg);
if (!msgIsProj) {
String followText = notifyMsg + " you!";
notification.setContentText(followText);
notification.setGroup(GROUP_KEY_FOLLOWERS);
Log.d(Constants.DEBUG, "SETTING AS FOLLOWers" + unread_notif);
} else {
notification.setContentText(notifyMsg + " " + notifyItemName);
notification.setGroup(GROUP_KEY_PROJECTS);
}
notification.setTicker(getString(R.string.titlePushNotify));
notification.setSmallIcon(R.drawable.ic_pushnotify);
//notification.setGroupSummary(true);
PendingIntent contentIntent = PendingIntent.getActivity(this, id,
newIntentMsg, PendingIntent.FLAG_CANCEL_CURRENT);
notification.setContentIntent(contentIntent);
notification.setAutoCancel(true);
manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if(notifyMsg != null && !notifyMsg.equals("")) {
manager.notify(id, notification.build());
unread_notif++;
Log.d(Constants.DEBUG, "PRE MORE NOTIF" + unread_notif);
if (unread_notif>1) {
Log.d(Constants.DEBUG, "GETTING MORE NOTIF" + unread_notif);
Notification summaryNotification = new NotificationCompat.Builder(this)
.setContentTitle("Your summary message")
.setSmallIcon(R.drawable.ic_pushnotify)
.setStyle(new NotificationCompat.InboxStyle()
.addLine("Details about your first notification")
.addLine("Details about your second notification")
.setBigContentTitle(Integer.toString(unread_notif)+" new notifications")
.setSummaryText("More details in app"))
.setGroup(GROUP_KEY_FOLLOWERS)
.setGroupSummary(true)
.build();
manager.notify(id++, summaryNotification);
}
}

For Firebase notifications,onMessageReceive is called when the app is in the foreground if you app if is background, the Google Services will take care of displaying your message.
Now notifications are handled using two ways:
- notification payload
- data payload
Notifications are managed when the app in the foreground using DATA Payload and using NOTIFICATION payload they are handled when the app in background or killed.
So, the solution for this is ditch the notification object from your message payload. Removing the notification object at backend will consider data payload object as default as you won't face this problem anymore.
