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.

How to schedule recurring notifications in kotlin?

I've been looking for this for a couple of hours but I haven't found anything helpful. Right now, I have an activity (called other_recurringreminder) that sets a time (fomartted calendar, HH:mm; string), repetition frequency (int), repetition unit (like minutes, hours, days; string), whether it's on or off (bool), and a name (string)
In other_recurringreminder.kt, I have this function:
fun sendnotification()
{
val channelID = "channel1"
val notificationID = 1
val sharedPreferences: SharedPreferences = getSharedPreferences("sharedPrefs", Context.MODE_PRIVATE)
val builder = NotificationCompat.Builder(this, "channelID")
.setSmallIcon(R.drawable.centr)
.setColor(resources.getColor(R.color.purple))
.setContentTitle(sharedPreferences.getString("Alarm1Name_USERPREFS", "Reminder 1"))
.setContentText(getString(R.string.notif_recurringreminders))
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setAutoCancel(true)
with(NotificationManagerCompat.from(this)) {
notify(notificationID, builder.build())
}
}
Which sends the notification when called.
How can I make it so that my app sends this notification at a time from SharedPreferences, with a title from SP, and repeats every x units from SP?
Should this function be in another kotlin file?
Can this work even after a restart, when my app hasn't yet been opened?If I want to schedule more than one notif with different values, do I need to duplicate anything?
Sorry if it's a dumb question, I'm fairly new to kotlin. and thanks!

you can use alarm manager for it.
first create a class with broadcast receiver like
class AlarmReceiver : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent?) {
Log.d("this", "notify")
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val intent = Intent(context, AlarmActivity2::class.java)
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK)
val pendingIntent = PendingIntent.getActivity(context, 0, intent, 0)
val builder = NotificationCompat.Builder(context, "111")
.setSmallIcon(R.drawable.blue_stringart)
.setContentTitle("Alarm is running")
.setAutoCancel(true)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setDefaults(NotificationCompat.DEFAULT_SOUND)
.setDefaults(NotificationCompat.DEFAULT_VIBRATE)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.addAction(R.drawable.ic_baseline_stop_24,"Stop",pendingIntent)
.setContentIntent(pendingIntent)
val notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM)
val r = RingtoneManager.getRingtone(context, notification)
r.play()
val notificationManagerCompat = NotificationManagerCompat.from(context)
notificationManagerCompat.notify(123, builder.build())
}
}
}
after that go to your activity class make 2 method and call in oncreate
private fun setAlarm1() {
var calender: Calendar
calender = Calendar.getInstance()
calender.set(Calendar.HOUR_OF_DAY, PUT_YOUR_ALARM HOUR)
calender.set(Calendar.MINUTE, PUT_YOUR_ALARM MINUTE)
calender.set(Calendar.SECOND, 0)
alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager
val thuReq: Long = Calendar.getInstance().timeInMillis + 1
var reqReqCode = thuReq.toInt()
if (calender.timeInMillis < System.currentTimeMillis()) {
calender.add(Calendar.DAY_OF_YEAR, 1)
}
val alarmTimeMilsec = calender.timeInMillis
val intent = Intent(this, AlarmReceiver::class.java)
intent.setFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK)
val pendingIntent = PendingIntent.getBroadcast(this, reqReqCode, intent, 0)
alarmManager.setRepeating(
AlarmManager.RTC_WAKEUP,
calender.timeInMillis,
HERE_PUT_YOUR_HOUR * 60 * 60 * 1000,
pendingIntent
)
private fun createNotificationChannel() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val name = "Alarmclock Channel"
val description = " Reminder Alarm manager"
val importance = NotificationManager.IMPORTANCE_HIGH
val notificationChannel = NotificationChannel(CHANNELID, name, importance)
notificationChannel.description = description
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.createNotificationChannel(notificationChannel)
}
}
Note - Must to do(go to your app setting and give notification permission on) 1.alarmManager.setRepeating here you can use your alarm type as your wish. 2.requestcode must be unique for each alarm. 3. you must take a alarm time and keep in calender.timeInMillis which is you expecting alarm time.

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)
}

How to open app when notification is clicked in android?

I already made a notification without intent to MainActivity and it works fine, but when I add that intent to my MainActivity the notification does not show anymore. Is there anything wrong with my code or do I need to change the manifest or add some code in my MainActivity?
Here is my code. I set it into two functions - setDailyReminder and showAlarmNotification.
fun setDailyReminder(context: Context, type: String, message: String) {
val alarmManager = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager
val intent = Intent(context, MainActivity::class.java)
intent.putExtra(EXTRA_MESSAGE, message)
intent.putExtra(EXTRA_TYPE, type)
val timeArray =
TIME_DAILY.split(":".toRegex()).dropLastWhile { it.isEmpty() }.toTypedArray()
val calendar = Calendar.getInstance()
calendar.set(Calendar.HOUR_OF_DAY, Integer.parseInt(timeArray[0]))
calendar.set(Calendar.MINUTE, Integer.parseInt(timeArray[1]))
calendar.set(Calendar.SECOND, 0)
val pendingIntent = PendingIntent.getBroadcast(context,
ID_DAILY, intent, 0)
alarmManager.setInexactRepeating(
AlarmManager.RTC_WAKEUP,
calendar.timeInMillis,
AlarmManager.INTERVAL_DAY,
pendingIntent
)
Toast.makeText(context, "Daily reminder set up", Toast.LENGTH_SHORT).show()
}
private fun showAlarmNotification(
context: Context,
title: String,
message: String?,
notifId: Int
) {
val CHANNEL_ID = "Github App"
val CHANNEL_NAME = "Let's find favourite user on Github"
val notificationManagerCompat =
context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val builder = NotificationCompat.Builder(context, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_play_circle_filled_white_24dp)
.setContentTitle(title)
.setContentText(message)
.setSound(alarmSound)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channel = NotificationChannel(
CHANNEL_ID,
CHANNEL_NAME,
NotificationManager.IMPORTANCE_DEFAULT
)
builder.setChannelId(CHANNEL_ID)
notificationManagerCompat.createNotificationChannel(channel)
}
val notification = builder.build()
notification.flags = notification.flags or Notification.FLAG_AUTO_CANCEL
notificationManagerCompat.notify(notifId, notification)
}

fun showNotification(context: Context,title: String, message:String, notifId: Int){
createNotificationChannel(context)
val intent = Intent(context, MainActivity::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
val pendingIntent = PendingIntent.getActivity(this, 0,
intent,PendingIntent.FLAG_ONE_SHOT)
var builder = NotificationCompat.Builder(context, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_play_circle_filled_white_24dp)
.setContentTitle(title)
.setContentText(message)
.setAutoCancel(true)
.setColor(resources.getColor(R.color.colorAccent))
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setContentIntent(pendingIntent)
val notificationManagerCompat = NotificationManagerCompat.from(this)
notificationManagerCompat.notify(notifId, builder.build())
}
private fun createNotificationChannel(context: Context) {
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val name = "Test"
val descriptionText = "FCM"
val importance = NotificationManager.IMPORTANCE_DEFAULT
val channel = NotificationChannel(CHANNEL_ID, name, importance).apply {
description = descriptionText
}
// Register the channel with the system
val notificationManager: NotificationManager =
context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.createNotificationChannel(channel)
}
}

cant push notification by date in kotlin

I try to push notification by date to my app. I allready build the broadcast reciever and for some reason it didn't push the notification.
This is my code:
saveTime?.setOnClickListener() //save time notification
{
val hour: Int = tp!!.hour
val min: Int = tp!!.minute
var text = "" + hour + ":" + min
var calendar: Calendar = Calendar.getInstance()
calendar.set(Calendar.DAY_OF_WEEK,1)
calendar.set(Calendar.DAY_OF_WEEK,Calendar.FRIDAY)
calendar.set(Calendar.HOUR_OF_DAY,hour)
calendar.set(Calendar.MINUTE,min)
calendar.set(Calendar.SECOND, 0);
val intent = Intent()
val pendingIntent = PendingIntent.getActivity(this.activity,0,intent,PendingIntent.FLAG_UPDATE_CURRENT)
var alarmManager = this.activity.getSystemService(ALARM_SERVICE) as AlarmManager
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,calendar.timeInMillis, AlarmManager.INTERVAL_DAY,pendingIntent)
}
And here you'll see my broadcast reciever class:
class MyReciver : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent) {
val timeAlert = System.currentTimeMillis()
val notificationManager = context
.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val notificationIntent = Intent(context, MainActivity::class.java)
notificationIntent.flags = Intent.FLAG_ACTIVITY_CLEAR_TOP
val pendingIntent = PendingIntent.getActivity(context, 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT)
//val alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val notification = Notification.Builder(context)
.setContentTitle("some title:")
.setContentText("some text")
.setSmallIcon(R.drawable.notification_icon_background)
.setAutoCancel(true).setWhen(timeAlert)
.setContentIntent(pendingIntent)
notificationManager.notify(0, notification.build())
}
}
