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

push notification show incorrect time kotlin, sometimes not showing

i want to show push notification in kotlin at 7 AM & 16PM in here every 24Hours everyday. i make 2 broadcast receiver & 2 declare time inside oncreate, but sometimes push notification not show, i dont know if receiver blocked by miui saver

I'm new to android development... trying to build application which send notification at specific time daily. But after that if I open application it shows notification every time on launch.. how to stop showing it again? please help me thank you

Iqbal,
you are sending an Alarm on
calendar.getTimeInMillis(),
It will return your current time in milliseconds. Hence alarm whenever you run on create. i.e. whenever you open the app. try different times. Or add 1000 * 60 * (min) in millis.

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)

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)
}

Android Notification Not Appearing As Heads Up

I am using the following to present notifications to users on Android which currently works fine but I am having an issue that the notification appears in the status bar but does not come up as a heads up like a Facebook or WhatsApp notification does on the device? I get the notification but have to pull down on the status bar to view it. I am wondering is there a way to make this appear on the top of the screen in bubble format or is this something that varies between phone settings?
Code is attached below:
MainActivity
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addNotification(10,"eventname","roomname");
addNotification(25,"eventname2","roomname2");
}
public void addNotification(int test, String test2, String test3){
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlarmReceiver.class);
intent.putExtra("test",test2);
intent.putExtra("test2",test3);
final int _id = 50;
Random random = new Random();
final int randomInt = random.nextInt();
System.out.println("random integer:" + randomInt);
PendingIntent appIntent = PendingIntent.getBroadcast(this, randomInt, intent,PendingIntent.FLAG_UPDATE_CURRENT);
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, test);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), appIntent);
}
}
AlarmReceiver
public class AlarmReceiver extends BroadcastReceiver{
private static final String CHANNEL_ID = "com.singhajit.notificationDemo.channelId";
#Override
public void onReceive(Context context, Intent intent) {
Intent notificationIntent = new Intent(context, NotificationActivity.class);
String passed = intent.getStringExtra("test");
String passed2 = intent.getStringExtra("test2");
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(NotificationActivity.class);
stackBuilder.addNextIntent(notificationIntent);
String messageBody = "Your event " + passed + " is about to start in 15 minutes, in room "+passed2;
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
Notification.Builder builder = new Notification.Builder(context);
builder.setStyle(new Notification.BigTextStyle(builder)
.bigText(messageBody)
.setBigContentTitle("UA Reloaded Event Starting")
.setSummaryText("Tap To View Info"))
.setContentText(messageBody)
.setSmallIcon(R.drawable.ic_launcher)
.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE)
.setPriority(Notification.PRIORITY_MAX);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
builder.setChannelId(CHANNEL_ID);
}
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
String name = "NotificationDemo";
String description = "NotificationDemo";
int importance = NotificationManager.IMPORTANCE_HIGH; //Important for heads-up notification
NotificationChannel channel = new NotificationChannel("1", name, importance);
channel.setDescription(description);
channel.setShowBadge(true);
channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
// NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(0, builder.build());
}
}

If you still need an answer or for anyone else in order to show the notification as heads-up you have to add your channel id to the Builder.
.setChannelId(CHANNEL_ID)
like so:
val notification = NotificationCompat.Builder(getContext(), CHANNEL_ID)
.setSmallIcon(...)
.setContentTitle(getContext().getString(R.string.app_name))
...
.setChannelId(CHANNEL_ID)
...
.build()
And don't forget about the NotificationChannel importance and notification priority (set them to high/max if needed)

You updated your channel importance, which is not possible as stated in the documentation (https://developer.android.com/training/notify-user/channels#CreateChannel).
So your problem should be resolved by changing the channelId to something other than "1", as the ids for Channels must be unique.
