title: Notification Content Title and Content Text are not shwoing
body: <p>I am generating local notification with multiple lines. All lines are showing properly but contentTitle and contentText are not showing.</p>
  
  <p>Here is my code to generate a notification:</p>
  
  <pre><code>Intent notificationIntent = new Intent(context, MainActivity.class);
  
  notificationIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
          Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);

  stackBuilder.addNextIntent(notificationIntent);
  
  
  int num = (int) System.currentTimeMillis();
  
  PendingIntent pendingIntent = stackBuilder.getPendingIntent(num, PendingIntent.FLAG_UPDATE_CURRENT);
  
  String id = "notification_channel_id";
  CharSequence name = "Message_Notification";
  Bitmap bm = BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher);
  
  NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context, id)
          .setSmallIcon(R.mipmap.ic_launcher)
          .setContentTitle("title")
          .setContentText("time")
          .setAutoCancel(true)
          .setGroupSummary(true)
          .setGroup(GROUP_KEY)
          .setContentIntent(pendingIntent)
          .setChannelId(id);
  
  if (subTitle != null) {
      NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
  
      inboxStyle.setBigContentTitle("Dose Reminder");
  
   if (subTitle.contains("---")) {
  
          String[] splitStrings = subTitle.split("---");
  
          for (int i = 0; i &lt; splitStrings.length; i++) {
              inboxStyle.addLine(splitStrings[i]);
          }
      } else {
          inboxStyle.addLine(subTitle);
  
          // Moves the expanded layout object into the notification object.
          notificationBuilder.setStyle(inboxStyle);
  
      }
  
      // Moves the expanded layout object into the notification object.
      notificationBuilder.setStyle(inboxStyle);
  }
  
  if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.LOLLIPOP) {
      notificationBuilder.setColor(ContextCompat.getColor(context, R.color.colorAccent));
  } else {
      notificationBuilder.setLargeIcon(bm);
  }
  
  if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.O) {
      NotificationManager notificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
  
      // The user.-visible description of the channel.
      String description = "Notifications contains messages which was sent by dev team.";
      int importance = NotificationManager.IMPORTANCE_MAX;
      NotificationChannel mChannel = new NotificationChannel(id, name, NotificationManager.IMPORTANCE_DEFAULT);
      // Configure the notification channel.
      mChannel.setDescription(description);
      mChannel.enableLights(true);
      // Sets the notification light color for notifications posted to this
      // channel, if the device supports this feature.
      mChannel.setLightColor(Color.RED);
      if (notificationManager != null) {
          notificationManager.createNotificationChannel(mChannel);
      }
  }
  
  // Sets an ID for the notification
  
  // Gets an instance of the NotificationManager service
  final NotificationManager mNotifyMgr =
          (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
  // Builds the notification and issues it.

  }
