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())
}

setFullScreenIntent is not coming to foreground in samsung Android OS 11

I am trying to show Call notification like whatsup with audio
I had implemented full screen notification for call using setFullScreenIntent and pending intents as below but in other devices I am getting notification to foreground except in Samsung device with OS 11.
var notificationBuilder: NotificationCompat.Builder? = null
val ringUri: Uri = Settings.System.DEFAULT_RINGTONE_URI
var contentView = RemoteViews(packageName, R.layout.call_notification_layout)
contentView.setOnClickPendingIntent(R.id.imgCallYes, receiveCallPendingIntent)
contentView.setOnClickPendingIntent(R.id.imgCallNo, cancelCallPendingIntent)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
notificationBuilder = NotificationCompat.Builder(
applicationContext,
CHANNEL_ID
)
.setSmallIcon(R.mipmap.ic_launcher)
.setContent(contentView)
.setCategory(NotificationCompat.CATEGORY_CALL)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setAutoCancel(true)
.setSound(ringUri)
.setFullScreenIntent(callDialogPendingIntent, true)
val notificationChannel = NotificationChannel(
CHANNEL_ID,
"My Notifications",
NotificationManager.IMPORTANCE_HIGH
)
val notificationManager = getSystemService(NOTIFICATION_SERVICE) as NotificationManager
// Configure the notification channel.
val att = AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_NOTIFICATION)
.setContentType(AudioAttributes.CONTENT_TYPE_SPEECH)
.build()
notificationChannel.setSound(ringUri, att)
notificationChannel.description = "body"
notificationChannel.enableLights(true)
notificationChannel.lightColor = Color.RED
notificationChannel.vibrationPattern = longArrayOf(0, 1000, 500, 1000)
notificationChannel.enableVibration(true)
notificationManager.createNotificationChannel(notificationChannel)
} else {
notificationBuilder =
NotificationCompat.Builder(applicationContext, CHANNEL_ID)
.setSmallIcon(R.mipmap.ic_launcher)
.setContent(contentView)
.setAutoCancel(true)
.setCategory(NotificationCompat.CATEGORY_CALL)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setSound(ringUri)
.setFullScreenIntent(callDialogPendingIntent, true)
}
var incomingCallNotification: Notification? = null
if (notificationBuilder != null) {
incomingCallNotification = notificationBuilder.build()
}
startForeground(NOTIFICATION_ID, incomingCallNotification)

IN Android 12 I added PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT for pending intent, now notification is coming

Android custom notification sound not working on some device

I have set custom sound for notification. It's working for some device but not working on some device mostly Xiaomi device.
I have used this code:
private fun createNotificationChannel(){

val notificationManagerCompat = NotificationManagerCompat.from(context)
preChannelIds.forEach {
deleteChannel(notificationManagerCompat,it)
}
if ( Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
val attributes = getAudioAttributes()
val soundUri = getSoundUri(context)
val importance = NotificationManagerCompat.IMPORTANCE_HIGH
val channelBuilder = NotificationChannelCompat.Builder(channelId, importance).apply {
setName(channelName)
setDescription(channelDescription)
setSound(soundUri, attributes)
setVibrationPattern(vibrationPattern)
setLightsEnabled(true)
setShowBadge(true)
}
val channel = channelBuilder.build()
notificationManagerCompat.createNotificationChannel(channel)
}
}
fun sendNotification(title:String, message:String){
val context = AppApplication.getContext()
val intent = ....
val notificationManagerCompat = NotificationManagerCompat.from(AppApplication.getContext())
val pendingIntent = PendingIntent.getActivity(

.setContentIntent(pendingIntent)
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O){
notificationBuilder.priority = NotificationCompat.PRIORITY_MAX
notificationBuilder.setSound(getSoundUri(context))
}
val notification = notificationBuilder.build()
notification.flags = Notification.FLAG_INSISTENT
notificationManagerCompat.notify(notificationRequestCode, notification)
}
Please help me to solve this issue for some device. Is there any other solution for this issue.

Firebase Cloud Messaging received BUT doesn't Popup!!! - KOTLIN

This is my code!
I'm building an application that receives notifications from firebase.
The App receiving the notification but doesn't popup it.
Any Help!
class MyFirebaseMessagingService : FirebaseMessagingService() {
val TAG = "FirebaseMessagingService"
override fun onMessageReceived(p0: RemoteMessage) {
super.onMessageReceived(p0)
Log.d(TAG, "{$p0}")
if (p0.notification !=null){
showNotification(p0.notification?.title, p0.notification?.body)
}
}
private fun showNotification(title: String?, body: String?){
val intent=Intent(applicationContext, MainActivity::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
val pendingIntent=PendingIntent.getActivities(
this,
0,
arrayOf(intent),
PendingIntent.FLAG_UPDATE_CURRENT
)
//val soundUri=RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val notificationBuilder = NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_logo_border)
.setContentTitle(title)
.setContentText(body)
.setAutoCancel(true)
.setContentIntent(pendingIntent)
.setPriority(2)
val notificationManager=getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.notify(0, notificationBuilder.build())
}
override fun onNewToken(token: String) {
super.onNewToken(token)
Log.d(TAG, "Refreshed token: $token")
}

I think it's because of the notification channel which came out with Android 8.0.
Call this function before building your notification.
private fun createNotificationChannel(context: Context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val notificationManager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val existingChannel = notificationManager.getNotificationChannel(CHANNEL_ID)
if (existingChannel == null) {
// Create the NotificationChannel
val name = context.getString(R.string.defaultChannel)
val importance = NotificationManager.IMPORTANCE_DEFAULT
val mChannel = NotificationChannel(CHANNEL_ID, name, importance)
mChannel.description = context.getString(R.string.notificationDescription)
notificationManager.createNotificationChannel(mChannel)
}
}
}
And use this with your code
NotificationManagerCompat.from(context).apply {
cancelAll() // Remove prior notifications; only allow one at a time.
notify(1 or your notification id, notificationBuilder.build())
}
instead of
val notificationManager=getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.notify(0, notificationBuilder.build())

val notificationBuilder = NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_notification_icon)
.setTicker(title)
.setAutoCancel(true)
.setContentTitle(title)
.setContentIntent(pendingIntent)
.setStyle(NotificationCompat.BigTextStyle().bigText(message))
.setSound(defaultSoundUri)
.setContentText(message)
if (bitmap != null) {
notificationBuilder.setLargeIcon(bitmap)
}
val notificationManager = applicationContext.getSystemService(NOTIFICATION_SERVICE) as NotificationManager
// Since android Oreo notification channel is needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channel = NotificationChannel(channelId,
channelName,
NotificationManager.IMPORTANCE_HIGH)
notificationManager.createNotificationChannel(channel)
}
notificationManager.notify(notificationId, notificationBuilder.build())

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())
}
