Vibrate functionality implementing in FCM

I am implementing FCM in my app. I want my device to vibrate and blink led on receiving notification. But it seems to not work as i expected. Is there any way to achieve this with FCM. Here's my code:
private fun sendNotification(messageBody: String?) {
val intent = Intent(this, HomeActivity::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
val pendingIntent = PendingIntent.getActivity(
this, 0, intent, PendingIntent.FLAG_ONE_SHOT)
val channelId = "my_channel_id"
val defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val notificationBuilder = NotificationCompat.Builder(applicationContext, channelId)
.setAutoCancel(true)
.setSmallIcon(R.drawable.splash_icon)
.setContentText(body)
.setContentTitle(title)
.setContentIntent(pendingIntent)
.setSound(defaultSoundUri)
.setVibrate(longArrayOf(1000, 1000, 1000, 1000))
.setLights(0, 2000, 500)
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channel =
NotificationChannel(channelId, "app", NotificationManager.IMPORTANCE_DEFAULT)
notificationManager.createNotificationChannel(channel)
}
notificationManager.notify(0, notificationBuilder.build())
}

Forground service notification get replaced by another notification

I have two forground service FS1 and FS2 , with each one i create notification , if FS1 is running and i start FS2 the old notification get replaced , i want both to stay ,
this is how i create notification
private fun createNotification(): Notification {
val notificationChannelId = "123"
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val channel = NotificationChannel(
notificationChannelId,
"Notification service channel",
NotificationManager.IMPORTANCE_HIGH
).let {
it.description = "Notification Service channel"
it.enableLights(true)
it.lightColor = Color.RED
it.enableVibration(true)
it.vibrationPattern = longArrayOf(100, 200, 300, 400, 500, 400, 300, 200, 400)
it
}
notificationManager.createNotificationChannel(channel)
}
val pendingIntent: PendingIntent = Intent(this, MainActivity::class.java).let { notificationIntent ->
PendingIntent.getActivity(this, 0, notificationIntent, 0)
}
val builder: Notification.Builder = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) Notification.Builder(
this,
notificationChannelId
) else Notification.Builder(this)
return builder
.setContentTitle("title")
.setContentText("Content")
.setContentIntent(pendingIntent)
.setSmallIcon(R.drawable.notification_icon)
.setTicker("Ticker text")
.setPriority(Notification.PRIORITY_HIGH)
.build()
}
and in the onCreate methode
val notification = createNotification()
startForeground(1, notification)
and in the other service i create notification with the same way !

Ok my bad , i found out why , at onCreate methode , in both services i was using id 1 , i should use different id

why my notification sometimes does not appear in status bar?

I try to display a notification using the code like this
var notification = NotificationCompat.Builder(this, "Info")
.setSmallIcon(R.drawable.ic_stat_ic_notification)
.setContentTitle(notificationMessage.title)
.setContentText(notificationMessage.body)
.setContentIntent(setUpPendingIntent(this))
.setAutoCancel(true)
.setOnlyAlertOnce(true)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
val build = notification.build()
notificationManager.notify(1, build)
and when I create the channel, I use this code
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val infoChannel = NotificationChannel(
NOTIFICATION_CHANNEL_INFO,
NOTIFICATION_CHANNEL_INFO,
NotificationManager.IMPORTANCE_DEFAULT
)
val notificationManager = getSystemService(NOTIFICATION_SERVICE) as NotificationManager
notificationManager.createNotificationChannel(infoChannel)
}
but sometimes, it does not appear in status bar for Android pie and above ? what should I do ?

Notification Not Showing In Android Studio

I'm using Kotlin and Android Studio to try and push a Notification in a test app. I followed the instructions in the Android Developers site on How to create a Notification (https://developer.android.com/training/notify-user/build-notification) but I seem to be doing something wrong as my Notification is not showing anywhere. Here's my code:
val intent = Intent(context, Profile::class.java)
val pendingIntent = PendingIntent.getActivity(this.context, 0, intent, 0);
val builder = NotificationCompat.Builder(this.context)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Hello World!")
.setPriority(NotificationCompat.PRIORITY_MAX)
builder.setContentIntent(pendingIntent).setAutoCancel(true)
val mNotificationManager = message.context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
with(mNotificationManager) {
notify(123, builder.build())
I really don't know what I'm missing so I would be grateful for any help.

According to your code, you are not creating a Notification channel.
Notification channel is necessary from Android Oreo and above
So if you are running the app Android O and above devices without a notification channel, your notification won't show up.
Create Notification Channel
fun createNotificationChannel() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channelId = "all_notifications" // You should create a String resource for this instead of storing in a variable
val mChannel = NotificationChannel(
channelId,
"General Notifications",
NotificationManager.IMPORTANCE_DEFAULT
)
mChannel.description = "This is default channel used for all other notifications"
val notificationManager =
mContext.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.createNotificationChannel(mChannel)
}
}
Then create a notification using the same channelId while creating a notification.
createNotificationChannel()
val channelId = "all_notifications" // Use same Channel ID
val intent = Intent(context, Profile::class.java)
val pendingIntent = PendingIntent.getActivity(this.context, 0, intent, 0);
val builder = NotificationCompat.Builder(this.context, channelId) // Create notification with channel Id
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Hello World!")
.setPriority(NotificationCompat.PRIORITY_MAX)
builder.setContentIntent(pendingIntent).setAutoCancel(true)
val mNotificationManager =
message.context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
with(mNotificationManager) {
notify(123, builder.build())
Hope it helps.

try something like
val intent = Intent(context, Profile::class.java)
val pendingIntent = PendingIntent.getActivity(this.context, 0, intent, 0)
val mNotificationManager =
message.context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
mNotificationManager
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {//Don't forget this check
val channel = NotificationChannel (
channelId,
"my_notification",
NotificationManager.IMPORTANCE_HIGH
)
channel.enableLights(true)
channel.lightColor = Color.GREEN
channel.enableVibration(false)
val builder = NotificationCompat.Builder(this.context, "channel_id")
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Hello World!")
.setPriority(NotificationCompat.PRIORITY_MAX)
builder.setContentIntent(pendingIntent).setAutoCancel(true)
mNotificationManager.createNotificationChannel(channel)//Notice this
mNotificationManager.notify(123, builder.build())
}
else {
//Create Notifcation for below Oreo
}
Does your Logcat say something like:
E/NotificationManager: notifyAsUser: tag=null, id=123, user=UserHandle{0}
Also have a look at your line:
val intent = Intent(context, Profile::class.java)
IF all else fails create a test Actvity with hello world.
And then make the line look like:
val intent = Intent(context, testActivity::class.java)
Remember to add the activity to your Manifest
The following line
val pendingIntent = PendingIntent.getActivity(this.context, 0, intent, 0);
should not have a semi colon. Kotin doesn't need this.
Is Profile your Class or System Class?

Try out this method and you can pass message and title dynamically :
private fun showNotification(title: String?, body: String?) {
val intent = Intent(this, Profile::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
val pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT)
val soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val notificationBuilder = NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(title)
.setContentText(body)
.setAutoCancel(true)
.setSound(soundUri)
.setContentIntent(pendingIntent)
val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.notify(0, notificationBuilder.build())
}

notification sound and vibration does not work in android 8.1

here is my code
val intent = Intent("com.sbs16.ensofia.OPEN")
//intent.putExtra(MSDConstants.ACTIVITY_NOTIFICATION_TYPE, mType)
//intent.putExtra(MSDConstants.ACTIVITY_NOTIFICATION_ID, mId)
//intent.putExtra(MSDConstants.ACTIVITY_NOTIFICATION_URL, mUrl)
val pendingIntent = PendingIntent.getBroadcast(applicationContext, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT)
val notificationBuilder =
NotificationCompat.Builder(this, getString(R.string.notification_channel_id))
.setContentTitle(getString(R.string.app_name))
.setContentText(body)
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setLargeIcon(BitmapFactory.decodeResource(resources, R.drawable.icon_notifications))
.setColor(resources.getColor(R.color.red))
.setLights(Color.RED, 1000, 300)
.setDefaults(Notification.DEFAULT_VIBRATE)
.setSmallIcon(R.drawable.icon_notifications)
var notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
val importance = NotificationManager.IMPORTANCE_DEFAULT
val id = getString(R.string.notification_channel_id)
val name = getString(R.string.notification_channel_name)
val description = getString(R.string.notification_channel_description)
val channel = NotificationChannel(id, name, importance)
channel.description = description
channel.enableLights(true);
channel.lightColor = Color.RED;
channel.enableVibration(true);
notificationManager.createNotificationChannel(channel)
}
notificationManager.notify(0, notificationBuilder.build())
