FCM Foreground and Background notification layout view and PendingIntent

I'm creating notification using Firebase and FCM
class FcmServices: FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage) {
sendNotification(remoteMessage)
}
override fun onNewToken(token: String) {
super.onNewToken(token)
}
private fun sendNotification(remoteMessage: RemoteMessage) {
val notifTitle = remoteMessage.notification?.title
val notifBody = remoteMessage.notification?.body
val builder: NotificationCompat.Builder?
val notificationManager =
this.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val channelId = "101"
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val importance = NotificationManager.IMPORTANCE_DEFAULT
val notificationChannel = NotificationChannel(channelId, "notification", importance)
notificationManager.createNotificationChannel(notificationChannel)
builder = NotificationCompat.Builder(applicationContext, notificationChannel.id)
} else {
builder = NotificationCompat.Builder(applicationContext)
}
val intent = Intent(this, NotifikasiActivity::class.java)
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
val pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT)
builder.setSmallIcon(R.drawable.logo_bprmsa)
.setLargeIcon(
BitmapFactory.decodeResource(
this.resources,
R.drawable.logo_bprmsa
)
)
.setContentIntent(pendingIntent)
.setContentTitle(notifTitle)
.setContentText(notifBody)
.setDefaults(Notification.DEFAULT_VIBRATE)
var alarmSound: Uri? = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
if (alarmSound == null) {
alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE)
if (alarmSound == null) {
alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
}
}
builder.setSound(alarmSound)
builder.setAutoCancel(true)
builder.setWhen(System.currentTimeMillis())
builder.setDefaults(NotificationCompat.DEFAULT_VIBRATE)
builder.priority = NotificationCompat.PRIORITY_HIGH
notificationManager.notify(Random().nextInt(), builder.build())
}
}
I need to open the NotificationActivity after click the notification received from Firebase, but the problem is the PendingIntent is not working while the app is in background state. Is there any different condition between foreground and background state code ?
And for the second, the layout of foreground and background is also different (background state without the icon shown)

https://firebase.google.com/docs/cloud-messaging/concept-options
Based on the official document from Google, it is intentional. The Icon and any other buttons or others you wish to display other than the title and the message won't display if your app is not running foreground.

Not getting heads up notifications for a while when you swipe up local notifications

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.

chatChannel.setShowBadge(false)
chatChannel.group = MESSAGE_GROUP_ID
chatChannels.add(chatChannel)

Notification works in Activity but not in Service

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
val mainPendingIntent = PendingIntent.getActivity(
applicationContext, BuildConfig.REQUEST_CODE,
Intent(applicationContext, MainActivity::class.java),
PendingIntent.FLAG_UPDATE_CURRENT
)
NotificationManagerCompat.from(applicationContext)
.notify(BuildConfig.NOTIFICATION_ID, builder.build())
I use:
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
// Since android Oreo notification channel is needed.
setupChannels(notificationManager, builder)
// Create pending intent, mention the Activity which needs to be triggered
// when user clicks on notification.
val notificationId = Random.nextInt()
navigateToScreen(builder, notificationId)
val notification = builder.build()
notificationManager.notify(notificationId, notification)
}
private fun setupChannels(notificationManager: NotificationManager,
builder: NotificationCompat.Builder) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channelId = "channel_email_1"
val channel = NotificationChannel(channelId, "title",
NotificationManager.IMPORTANCE_DEFAULT).apply {
description = "body"
// Add other settings.
lockscreenVisibility = Notification.VISIBILITY_PUBLIC
canShowBadge()
setShowBadge(true)
}
notificationManager.createNotificationChannel(channel)
builder.setChannelId(channelId)
}
}
private fun navigateToScreen(builder: NotificationCompat.Builder,
notificationId: Int) {
val intent = Intent(this, MainActivity::class.java)
val pendingIntent = PendingIntent.getActivity(this, notificationId, intent,
PendingIntent.FLAG_UPDATE_CURRENT)
builder.setContentIntent(pendingIntent)
}

Notification is not working(Android Studio)

I am new to android studio. I was trying to create a notification when user click on a button embedded in recyclerView
user has to give time in Hours and Minutes only. I take user input as a string. And input is stored in SQLite database.
notifyMeUpdate function is working fine but Toast in Receiver class is not shown(I think Receiver class is not triggered).
Please ignore typo
Here is my code:
class User{
var id = 0
var time = ""
var amp = ""
var text = ""
var notifyMe = false
}
My User Class:
fun notifyMeUpdate(user: User) {
alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager
var hour = 0
var min = 0
for(i in 0 until user.time.length) {
if (user.time[i] == ':'){
var str = user.time.subSequence(0, i).toString()
var minStr = user.time.subSequence(i+1, user.time.length).toString()
if(user.amp == "AM"){
hour = str.toInt()
min = minStr.toInt()
}
else{
hour = str.toInt() + 12
min = minStr.toInt()
}
}
}
val cur_cal: Calendar = GregorianCalendar()
cur_cal.timeInMillis = System.currentTimeMillis()
val cal: Calendar = GregorianCalendar()
cal.add(Calendar.DAY_OF_YEAR, cur_cal[Calendar.DAY_OF_YEAR])
cal[Calendar.HOUR_OF_DAY] = hour
cal[Calendar.MINUTE] = min
cal[Calendar.SECOND] = 0
cal[Calendar.MILLISECOND] = cur_cal[Calendar.MILLISECOND]
cal[Calendar.DATE] = cur_cal[Calendar.DATE]
cal[Calendar.MONTH] = cur_cal[Calendar.MONTH]
val intent = Intent(context, Receiever::class.java)
val pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT)
alarmManager.set(AlarmManager.RTC_WAKEUP, cal.timeInMillis, pendingIntent)
}
And here is my Receiever class
class Receiever: BroadcastReceiver(){
lateinit var notificationManager: NotificationManager
lateinit var notificationChannel: NotificationChannel
lateinit var builder: Notification.Builder
private var channelId = "package com.example.recyclerpractise"
private var description = "Text Notification"
override fun onReceive(context: Context?, intent: Intent?){
Toast.makeText(context, "Triggred", Toast.LENGTH_SHORT).show()
val intent = Intent(context, LauncherActivity::class.java)
val pintent = PendingIntent.getActivity(context, 0 , intent, PendingIntent.FLAG_UPDATE_CURRENT)
if (context != null) {
notificationManager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
notificationChannel =
NotificationChannel(channelId, description, NotificationManager.IMPORTANCE_HIGH)
notificationChannel.enableLights(true)
notificationChannel.lightColor = Color.GREEN
notificationChannel.enableVibration(true)
notificationManager.createNotificationChannel(notificationChannel)
if (context != null) {
builder = Notification.Builder(context, channelId)
.setContentTitle("Hello Moto")
.setContentText("Test Notification")
.setSmallIcon(R.drawable.ic_launcher_foreground)
.setLargeIcon(BitmapFactory.decodeResource(context.resources, R.drawable.ic_launcher_foreground))
.setContentIntent(pintent)
}
else{
builder = Notification.Builder(context)
.setContentTitle("Hello Moto")
.setContentText("Test Notification")
.setSmallIcon(R.drawable.ic_launcher_foreground)
.setLargeIcon(BitmapFactory.decodeResource(context?.resources, R.drawable.ic_launcher_foreground))
.setContentIntent(pintent)
}
notificationManager.notify(19867, builder.build())
}
}
}
Here is my onBindViewHolder of recycler list
override fun onBindViewHolder(p0: ViewHolder, p1: Int) {
val user: User = userList[p1]
p0.time.text = user.time
p0.text.text = user.text
p0.img.setOnClickListener{
val popup = PopupMenu(activity, p0.img)
popup.inflate(R.menu.schedulemenu)
popup.setOnMenuItemClickListener {
when(it.itemId){
R.id.menu_delete->{
activity.dbHelper.deleteData(userList[p1].id.toLong())
activity.refreshList()
}
R.id.menu_update->{
activity.updateUser(userList[p1])
}
R.id.notify->{
activity.notifyMeUpdate(userList[p1])
}
}
true
}
popup.show()
}
}
Thanks for Help

Thanks for all who tried. After several hours of debugging. I found that I did a very stupid mistake that haven't register my receiver in manifest file now it's working fine.

Android: Service doesn't work after screen is off

I am trying to create service which will be fetch data from server (periodicaly) and send notification to user. I achieved almost my goal, but service stops work when screen is off. When I turn on my phone I get plenty of notifications from previous time.
Service code:
class MyService: Service() {
override fun onCreate() {
super.onCreate()
val handler = Handler()
val runnable = object: Runnable {
override fun run() {
getDataFromServer()
handler.postDelayed(this, 1800000)
}
}
handler.post(runnable)
}
private fun getDataFromServer() {
// fetch data
displayNotification(description)
}
private fun displayNotification(description: String) {
val intent = Intent(this, MainActivity::class.java)
val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val notificationId = (0..300).random()
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val adminChannelName = "Messages channel"
val adminChannelDescription = "Notification about new data"
NotificationChannel(ADMIN_CHANNEL_ID, adminChannelName, NotificationManager.IMPORTANCE_HIGH).apply {
description = adminChannelDescription
enableLights(true)
lightColor = Color.RED
enableVibration(true)
notificationManager.createNotificationChannel(this)
}
}
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
val pendingIntent = PendingIntent.getActivity(
this, 0, intent, PendingIntent.FLAG_ONE_SHOT
)
val notificationSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val notificationBuilder = NotificationCompat.Builder(this, ADMIN_CHANNEL_ID)
.setSmallIcon(R.drawable.icon_small)
.setContentTitle(getText(R.string.notification_new_data_title))
.setContentText(getString(R.string.notification_new_data_text, description))
.setAutoCancel(true)
.setSound(notificationSoundUri)
.setContentIntent(pendingIntent)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
notificationBuilder.color = ContextCompat.getColor(context, R.color.icon_background)
}
notificationManager.notify(notificationId, notificationBuilder.build())
}
override fun onBind(intent: Intent): IBinder ? {
return null
}
}
Thank you for your help!

Try to start you service using the startForegroundService instead of startService, whether you need a background service, you can convert you Service to JobIntentService:
