I have tried many solutions but none of them are worked. I am able receive FCM notification when app is active, but not getting notification when app is background or killed.
you need to create a service class extending FirebaseMessagingService and override onMessageReceived method in that class to send notification
class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(message: RemoteMessage) {
super.onMessageReceived(message)
try {
message.notification?.let {
showNotification(
it.title ?: "",
it.body ?: ""
)
}
} catch (e: Exception) {
e.printStackTrace()
}
}
}
you are now getting the notification info from backend and showing it as a notification by using the function showNotification. of course, you must implement the function showNotification. it just a simple function for showing notifications in android
Edit: this the implementation of the function, add this to your class
class MyFirebaseMessagingService : FirebaseMessagingService() {
companion object {
const val channelId = "Channel"
const val channelName = "MyChannel"
const val smallIcon: Int = R.drawable.ic_logo
const val notificationId = 1
}
fun showNotification(myTitle: String, myBody: String) {
val notificationBuilder = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
Notification.Builder(applicationContext, channelId)
} else {
Notification.Builder(applicationContext)
}
val intent = Intent(applicationContext, HomeActivity::class.java)
val pendingIntent = PendingIntent.getActivity(
applicationContext,
0,
intent,
PendingIntent.FLAG_UPDATE_CURRENT
)
val notificationManager =
applicationContext.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
when {
Build.VERSION.SDK_INT >= 26 -> {
val channel = NotificationChannel(
channelId,
channelName,
NotificationManager.IMPORTANCE_DEFAULT
)
notificationManager.createNotificationChannel(channel)
notificationBuilder
.setContentIntent(pendingIntent)
.setContentText(myBody)
.setSmallIcon(smallIcon)
.setContentTitle(myTitle)
}
Build.VERSION.SDK_INT >= 24 -> notificationBuilder
.setContentText(myBody)
.setContentTitle(myTitle)
.setSmallIcon(smallIcon)
.setContentIntent(pendingIntent)
else -> notificationBuilder
.setContentText(myBody)
.setContentTitle(myTitle)
.setSmallIcon(smallIcon)
.setContentIntent(pendingIntent)
}
notificationManager.notify(notificationId, notificationBuilder.build())
}
}
If you want to get notification when app is background or killed your json object has to be this like:
{
"data":{
"title" : "your_title",
"body" : "your_body"
},
"to": "device_token",
"priority": "high"
}
You can catch notification onMessageReceived

When I swipe up after the local notification comes, the application notifications don't appear on the screen for a while. What could be the reason for this? I've read something that when heads up notifications are swiped up, it sends a warning to the system to prevent heads up notifications for a certain period of time, but how can I prevent this? I don't have any problems getting notifications in my app other than that.

I am trying to integrate Firebase Cloud Messages into my app. The code I used in the showNotification function is from the Android User Interface Samples. I tried it in the Activity and it worked but am not sure why it's not working in the service. The println is showing the function is getting called and values are coming as expected. Is there anything am missing from the function?
class MessagingService : FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage) {
if (remoteMessage.data.isNotEmpty()) {
val message = Gson().fromJson(remoteMessage.data.toString(), Message.Res::class.java).payload!!
showNotification(message.title, message.body, message.count)
}
}
private fun showNotification(title: String?, body: String?, count: Int = 0) {
println("_print::showNotification(title:$title, body:$body, count:$count)")
val mainPendingIntent = PendingIntent.getActivity(
applicationContext, BuildConfig.REQUEST_CODE,
Intent(applicationContext, MainActivity::class.java),
PendingIntent.FLAG_UPDATE_CURRENT
)
val builder = NotificationCompat.Builder(applicationContext, "channel_email_1")
.setContentTitle(title)
.setContentText(body)
.setSmallIcon(R.mipmap.ic_launcher)
.setLargeIcon(BitmapFactory.decodeResource(resources, R.mipmap.ic_launcher_round))
.setContentIntent(mainPendingIntent)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setColor(ContextCompat.getColor(applicationContext, R.color.primary))
.setSubText(if (count > 1) "You have $count pending notifications" else title)
.setCategory(Notification.CATEGORY_EMAIL)
.setPriority(1)
.setVisibility(NotificationCompat.VISIBILITY_PRIVATE)
NotificationManagerCompat.from(applicationContext)
.notify(BuildConfig.NOTIFICATION_ID, builder.build())

Instead of

i am using Kotlin Navigation component architecture for my chat app, and i am using Firebase Messaging service to integrate push notification, my requirement is to hide or disable the notifications when i am on User chat screen.Please let me know, how can i achieve this.
this is my code of displaying notification
class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage?) {
Log.d(TAG, "From: ${remoteMessage?.from}")
remoteMessage?.data?.let {
Log.d(TAG, "data payload: " + remoteMessage.data.toString())
val params =remoteMessage.data.get("body")
val objects = JSONObject(params)
Log.e("JSON OBJECT", objects.toString())
val title = remoteMessage.data.get("title").toString()
sendNotification(messageBody,title, applicationContext)
} }
my notification class is:
fun NotificationManager.sendNotification(messageBody: String, title: String, applicationContext: Context) {
notificationManager = applicationContext.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
// TODO: Step 1.12 create PendingIntent
if(title.equals("Ride Request")) {
fragmentId = R.id.notificationFragment
}
else if(title.equals("Ride Accepted")) {
fragmentId = R.id.inboxFragment
}
else if(title.equals("New Message")) {
fragmentId = R.id.inboxFragment
}
// ---------- creating navgraph intent to open specific fragment ------------
var contentPendingIntent = NavDeepLinkBuilder(applicationContext)
.setComponentName(HomeActivity::class.java)
.setGraph(R.navigation.home_bottom_navigation)
.setDestination(fragmentId)
.setArguments(bundle)
.createPendingIntent()

I don't if this is the perfect but you can try it as well
If the user is in chat screen you can create a sharedPref and set value of the variable to true (that the user is in chat screen)
So in the onMessageReceived() check it the value of the sharedPref is true (which mean the user is in chat screen)
If it's true then don't send notifications if false send notification
To set the sharedPref value
In the onResume of that chat activity set to true
In the onPause set to false
try this
class InboxFragment : Fragment() {
companion object {
var userId: String? = null
}
override fun onStart() {
userId = navArgs.userId
}
override fun onStop() {
userId = null
}
}
class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage) {
...
if (InboxFragment.userId != remoteMessage.data.get("userId"))
sendNotification(messageBody, title, applicationContext)
}
}
An application receives push notifications. They can be different (payment, order, chat), so I have to show them all, not replacing old with new. A problem is that in old emulators (API 19) all push notifications are shown separately.
In newer emulators they are groupped into one, but (if I'm not mistaken) after 3 received notifications.
Data sent from FCM:
{
"to": "<push token>",
"data": {
"title": "Application name",
"message": "See a message",
"screen": "Main screen",
...
}
}
MyFirebaseMessagingService:
override fun onMessageReceived(remoteMessage: RemoteMessage) {
super.onMessageReceived(remoteMessage)
val soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val textStyle = NotificationCompat.BigTextStyle()
val title: String
val body: String
if (remoteMessage.data.isNullOrEmpty()) {
title = remoteMessage.notification?.title ?: ""
body = remoteMessage.notification?.body ?: ""
} else {
title = remoteMessage.data["title"] ?: ""
body = remoteMessage.data["message"] ?: ""
}
val notificationBuilder = NotificationCompat.Builder(this,
getString(R.string.default_notification_channel_id))
.setContentTitle(title)
.setContentText(body)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setStyle(textStyle)
.setSound(soundUri)
.setSmallIcon(R.drawable.ic_notification_icon)
.setAutoCancel(true) // Dismiss the notification on click.
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
// Since android Oreo notification channel is needed.
setupChannels(notificationManager, notificationBuilder)
// Create pending intent, mention the Activity which needs to be triggered
// when user clicks on notification.
val notificationId = Random.nextInt()
navigateToScreen(notificationBuilder, notificationId, remoteMessage)
val notification = notificationBuilder.build()
notificationManager.notify(notificationId, notification)
}
private fun setupChannels(notificationManager: NotificationManager,
notificationBuilder: NotificationCompat.Builder) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channelId = getString(R.string.default_notification_channel_id)
val channel = NotificationChannel(channelId, "title",
NotificationManager.IMPORTANCE_DEFAULT).apply {
description = "body"
enableLights(true)
enableVibration(true)
lightColor = Color.CYAN
lockscreenVisibility = Notification.VISIBILITY_PUBLIC
canShowBadge()
setShowBadge(true)
}
notificationManager.createNotificationChannel(channel)
notificationBuilder.setChannelId(channelId)
}
}
private fun navigateToScreen(notificationBuilder: NotificationCompat.Builder,
notificationId: Int,
remoteMessage: RemoteMessage) {
val intent = getNavigationIntent(remoteMessage)
val pendingIntent = PendingIntent.getActivity(this, notificationId, intent,
PendingIntent.FLAG_UPDATE_CURRENT)
notificationBuilder.setContentIntent(pendingIntent)
}
private fun getNavigationIntent(remoteMessage: RemoteMessage): Intent {

Open application after clicking on Notification
(12 answers)
Closed 3 years ago.
I can receive the notification sent from Firebase Cloud Messaging and show it to android device in here
when I click notification from my app, I expect it will go inside my app. but when I click the notification from my app it just doesn't do anything. it seems it can't be clicked.
so how to make it go to inside my app when I click the notification. here is the code I use
creating channel using this code
class App : Application() {
override fun onCreate() {
super.onCreate()
createNotificationChannels()
}
private fun createNotificationChannels() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val infoChannel = NotificationChannel(
NOTIFICATION_CHANNEL_INFO,
NOTIFICATION_CHANNEL_INFO,
NotificationManager.IMPORTANCE_DEFAULT
)
val importantNews = NotificationChannel(
NOTIFICATION_EVENT_UPDATES,
NOTIFICATION_EVENT_UPDATES,
NotificationManager.IMPORTANCE_HIGH
)
val notificationManager = getSystemService(NOTIFICATION_SERVICE) as NotificationManager
notificationManager.createNotificationChannel(infoChannel)
notificationManager.createNotificationChannel(importantNews)
}
}
}
and build notification using this code
private fun setUpNotification(title: String, message: String, type: String, imagePath: String) {
val channel = if (type == "Event Updates") NOTIFICATION_EVENT_UPDATES else NOTIFICATION_CHANNEL_INFO
var notification = NotificationCompat.Builder(this, channel)
.setSmallIcon(R.drawable.ic_stat_ic_notification)
.setContentTitle(title)
.setContentText(message)
.setAutoCancel(true)
.setOnlyAlertOnce(true)
if (type == "Event Updates") {
notification = notification
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_EVENT)
} else {
notification = notification
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
}
if (imagePath.isNotEmpty()) {
Glide.with(this)
.asBitmap()
.load(imagePath)
.into(object: SimpleTarget<Bitmap>() {
override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
notification = notification.setLargeIcon(resource)
val build = notification.build()
notificationManager.notify(1, build)
}
})
} else {
val build = notification.build()
notificationManager.notify(1, build)
}
}
}
you have to use pending intent to achive this
val pendingIntent: PendingIntent = PendingIntent.getActivity(context, 0, Intent(context, TimerService::class.java), 0)
notification.setContentIntent(pendingIntent)
