Two or more Foreground Notification with Progress is replacing each other while updating its progress

Question

I have a service that will run a upload task in foreground then showing a progress in the notification. Since a user may upload multiple times with different id request then the

Answer 1

You should pass different Id to get different notification.

In Your Code:

Use getId() method to get different Id for each notification:

private static final AtomicInteger c = new AtomicInteger(0);
 public static int getID() {
        return c.incrementAndGet();
    }

NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID_DEFAULT)
            .setSmallIcon(R.drawable.ic_file_upload_white_24dp)
            .setContentTitle(getString(R.string.app_name))
            .setContentText(caption)
            .setProgress(100, percentComplete, false)
            .setContentInfo(String.valueOf(percentComplete +"%"))
            .setOngoing(true)
            .setAutoCancel(false);

    NotificationManager manager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    manager.notify(getId(), builder.build());

    startForeground(getId(),builder.build()); // you need to pass different id here. Or i think this method is not there.

For android O you need notification channel:

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications",                      NotificationManager.IMPORTANCE_HIGH);

            // Configure the notification channel.
            notificationChannel.setDescription("Channel description");
            notificationChannel.enableLights(true);
            notificationChannel.setLightColor(Color.RED);
            notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
            notificationChannel.enableVibration(true);
            notificationChannel.setImportance(NotificationManager.IMPORTANCE_HIGH);
            notificationChannel.setSound(notification, Notification.AUDIO_ATTRIBUTES_DEFAULT);
            notificationManager.createNotificationChannel(notificationChannel);
        }

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);

        notificationBuilder.setAutoCancel(true)
                .setDefaults(Notification.DEFAULT_ALL)
                .setWhen(System.currentTimeMillis())
                .setSound(notification)
                .setContentIntent(pendingIntent)
                .setContentText(message)
                .setContentTitle(getResources().getString(R.string.app_name))
                .setSmallIcon(R.drawable.ic_visualogyx_notification)
                .setStyle(new NotificationCompat.BigTextStyle().bigText(message).setBigContentTitle(getResources().getString(R.string.app_name)))
                .setTicker("Hearty365")
                .setLargeIcon(BitmapFactory.decodeResource(this.getResources(), R.mipmap.ic_launcher_round));

        notificationManager.notify(getID(),notificationBuilder.build());
