Firebase notifications when app is closed - android

I have implemented Firebase notification in my Android application. When my app is running, notification is displayed with my custom layout, but when application is not running, the notification is displayed with the default layout. How can I change the notification layout to my layout when application is not running. Also, I store shared preferences to let user toggle notifications. But when app is not running the notification is displayed anyways. How can achieve that?
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
if(SettingsFragment.getReceiceNotification()){ //if user wants to receive notification
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
RemoteViews remoteViews = new RemoteViews(getPackageName(),R.layout.push_notification_layout);
remoteViews.setImageViewResource(R.id.push_notif_icon,R.mipmap.ic_bird_black);
Intent intent = new Intent(this,MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setContent(remoteViews);
notificationBuilder.setContentTitle("Radyo Türkkuşu");
notificationBuilder.setContentText(remoteMessage.getNotification().getBody());
notificationBuilder.setAutoCancel(true);
notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
notificationBuilder.setContentIntent(pendingIntent);
remoteViews.setTextViewText(R.id.push_title, "Radyo Türkkuşu");
remoteViews.setTextViewText(R.id.push_context, remoteMessage.getNotification().getBody());
//notificationBuilder.setLights (ContextCompat.getColor(MainActivity.context, R.color.pushColor), 5000, 5000);
notificationManager.notify(0,notificationBuilder.build());
}
}

Your problem is you using it with notification tray.
See this link
Messages with both notification and data payload, both background and foreground. In this case, the notification is delivered to the device’s system tray, and the data payload is delivered in the extras of the intent of your launcher Activity.
If you using {data:"something"}(data-message) with {notification:"something"}(display-message) while your app is in background the data payload will delivered to extras of the intent but not to the onMessageReceived() method.I assume you implement your code for showing notification, so when your app is in foreground onMessageReceived() is trigger and it display the desire notification you want but when it is not onMessageReceived() no get trigger instead android system will handle it with your notification payload. You just have remove {notification:"something"}(display-message/notification tray) from your server side code to always ensure onMessageReceived().
For anyone keep mention onMessageReceived() will always trigger no matter wether it is not foreground or background please visit this link

There are two types of FCM messages
Notification message
Data message
Messages which get sent from Firebase console are Notification message. In order to get message in onMessageReceived() use Data Message. Use below code at server side to send Data Notification message
{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"data" : {
"Nick" : "Mario",
"body" : "great match!",
"Room" : "PortugalVSDenmark"
},
}
Reference https://firebase.google.com/docs/cloud-messaging/concept-options#notifications_and_data_messages

Your code should never be triggered when your app is closed or running in the background. See this:Firebase Notification
What you need to do is check how the app start up, tap the notification or tap the launcher icon. To do this, some data should be add into the notification then retrieve them in the first start activity in your app. If you can retrieve them successfully, it means your app is launched by tapping the notification, then you can do what you want to do.

click event on firebase notification android

about event for click on notification:
I am searching since yesterday about that , what I found/understood: in FirebaseMessagingService will receive notification data , after will fire local notification, so need to add event in that local notification, I tried to add that many times with many ways but nothing worked …
after I tried to deleted notification files (firebase notification files, and local notification files) but still can receive notification. do you know how to know if the user clicked on the notification ?
To receive messages, use a service that extends FirebaseMessagingService. Your service should override the onMessageReceived and onDeletedMessages callbacks. It should handle any message within 20 seconds of receipt (10 seconds on Android Marshmallow). The time window may be shorter depending on OS delays incurred ahead of calling onMessageReceived. After that time, various OS behaviors such as Android O's background execution limits may interfere with your ability to complete your work.
For further info. you can visit the official website:
Link: https://firebase.google.com/docs/cloud-messaging/android/receive
Hope you'll get your answer here.
Step 1:
// Create an Intent for the activity you want to start
Intent intent = new Intent(this, MainActivity.class);
Step 2:
// Create the PendingIntent
PendingIntent pendingIntent = PendingIntent.getActivity(this, Calendar.getInstance().get(Calendar.MILLISECOND), intent, android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
Step3:
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID);
builder.setContentIntent(pendingIntent);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(NOTIFICATION_ID, builder.build());
Whenever a user clicks on notification MainActivity will be opened.

Android Notifications with customized appearance

As of now, I am using Firebase Cloud Messaging as my app's notification system. From my understanding, even the largest companies use GCM, which is now being replaced with FCM. I am stuck, however, with the limitations imposed by sending things as a "notification" pay load.
Firebase recieves data messages in OnMessageRecieved, and I am able to get my exact desired behavior through using this. However, for the past three months I noticed that my app's notifications were simply not working because data payloads aren't received when the app is in the background/ inactive. This is very frustrating as the only workaround I have found to actually send notifications that alert users is through sending notification payloads.
I don't know how to get my desired behavior with the notification payload as I have been with data payload, but I realize that having notifications display perfectly when the app is in the foreground is pointless if they don't display at all when the app is in the background.
What I'm wondering, and what I'd really appreciate guidance on, is if somebody could recommend a way to display notifications with my desired style rather than the default Firebase notification style. Just to elaborate, I currently have a fully functional system of allowing users to respond to messages through the notification and without opening the app, but only through the data payload.
I know there is a way to somehow send notifications in a customized fashion (adding intents, buttons, etc) when the app is in the background or not running because this is done by Facebook, WhatsApp, and many other apps on the market. I am aware of something called AlarmManagers, but unsure of how I could use them to get my desired behavior, or if this is what people use anyways.
Thank you, and please let me know if there is a way to customize the payload when the app is in the background or inactive, through onMessagesRecieved or any other methods. As of now, the only other solution would be to somehow send the message's contents to a service, but I've faced issues where services could not display notifications in the background without crashing the app and without being very hacky.
The only way I came up with is to send the data payload only, which should be delivered to the onMessageReceived callback despite the app's status (foreground/background).
Then you put all required fields to the data payload and build a notification from it. Here the map "data" is from remoteMessage.getData()
private void sendNotification(Map<String, String> data) {
String body = Optional.ofNullable(data.get("body")).orElse("");
if (body.isEmpty()) {
return;
}
Intent intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri sound = getSoundUri(Optional.ofNullable(data.get("sound")).orElse(""));
String defaultChannel = Build.VERSION.SDK_INT >= Build.VERSION_CODES.O
? NotificationChannel.DEFAULT_CHANNEL_ID
: DEFAULT_CHANNEL_ID;
String channel = Optional.ofNullable(data.get("android_channel_id")).orElse(defaultChannel);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channel)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle(getString(R.string.app_name))
.setContentText(body)
.setAutoCancel(true)
.setWhen(System.currentTimeMillis())
.setShowWhen(true)
.setContentIntent(resultPendingIntent);
if (sound != null)
notificationBuilder.setSound(sound);
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
if (notificationManager != null)
notificationManager.notify(0, notificationBuilder.build());
}

Can't start Application to particular activity on Notification click from FCM

I'm experiencing this problem: If I click on the notification and my app is closed, HomeActivity is opened instead of the requested one.
I'm raising the notification like this:
Intent intent = new Intent(context, ArticleActivity_.class);
intent.putExtra(ArticleActivity.KEY_ARTICLE_ID, articleId);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0 , intent,
PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(notification.getTitle())
.setContentText(notification.getBody())
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
Notification n = notificationBuilder.build();
n.flags |= Notification.FLAG_AUTO_CANCEL;
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 , n);
And everything works fine if the application is opened. But if I close it, after clicking on the notification, HomeActivity will be opened instead of the one I configured.
You are having this problem because that is how FCM works. There are 2 types of push notifications. The first type is "notification" and the second type is "data". Both can be visualize as a JSON payload:
"notification": {
//key values
}
"data": {
//your custom key values
}
There is a third type which is a combination of both.
The "notification" type will create a default visual notification with default behavior when the app is not in the foreground. And it will execute whatever your write inside onMessageReceived when the app is open. The second type "data" will always do what you code inside onMessageReceived.
From the Firebase web console, you can send "notification" type or the combined type. For sending only "data" you need to send it from Firebase Functions or from a Server (that complies with the FCM requisites).
There is a trick you can do to get your goal. Combined payload, that can be send from the Firebase web console, contains "notification" and "data". The "data" key-values are available after the user click the notification. That information is available as extra data from the intent opening the default launcher Activity, so there you can change your Activity.
In your launcher Activity, add the following:
String notification = getIntent().getStringExtra("your-key");
if (notification != null) {
startActivity(new Intent(this, YourActivity.class));
}
This way you can validate that the Activity is being opened because the default notification was clicked, and is always a String because payload in push FCM must be by rule always String. In other cases, if the user simply opened the app, then the String will be null, and you don't redirect the user.

I want to send information through notification

I am making an app for my university, now in which I want to send messages/information about events. How I can send info to them. I tried firebase but, it is working till push notification only. I want if someone clicks on the notification it should open a new activity with whole message/info any code reference will be very helpful.
use the payload to put information into your notification. this could be an event id. The text of your notification is is also set by your server.
Thanks to the payload, your app client knows what event ID was received with the notification (when notification was opened). Just ask your database about information from the received event id from the client and you have all you need.
public void getnotification() {
NotificationManager notificationmgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Intent intent = new Intent(this, your_acitivity.class);
PendingIntent pintent = PendingIntent.getActivities(this, (int) System.currentTimeMillis(), new Intent[]{intent}, PendingIntent.FLAG_UPDATE_CURRENT);
Notification notif = new Notification.Builder(this)
.setSmallIcon(R.drawable.shadow_fiend)
.setContentTitle(notif_title)//Title of the notification
.setContentText(notif_detail)//Description of the notification
.setContentIntent(pintent)
.setAutoCancel(true)
.build();
notificationmgr.notify(0, notif);
}
When the above function is called a notification is generated and by clicking the notification the user is redirected to a specific activity. In the intent replace the your_acitivity.class to whatever activity you want to be redirected when notification is clicked.
Feel free to comment if I misunderstood your requirements.

Remove notifications from tray

How can I remove all notifications in the notification tray that were sent by my server when the user clicks on one notifiaction?
I have a chatting-app and the user gets a notification for each message (if the app is not in foreground). When the user clicks on one of those notifications the app will be brought to foreground / will be started. After that has happened, I want all other notifications in the notification bar to disappear as well.
No, you dont have to save the ids of all notifications, you can simply call:
NotificationManager nManager = ((NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE));
nManager.cancelAll();
Use the following code to cancel a Notification:
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(NOTIFICATION_ID);
If you have different notifications that need to be canceled you have to save the ids that you used to create the Notification.
