如何禁用或关闭来自系统托盘的通知？

Question

Hy everyone, I am developing an app that use firebase cloud messaging. In this app, I am using BroadcastReceiver instead of FirebaseMessagingService.

Here, BroadcastReceiver is used to save/store notification data in SQLite either in foreground/background or app is been killed.

The problem I am facing is, app is showing two notifications(ie one from system tray and another from app). I don't want notification coming from system tray.

So, Is there any possible way to stop notification coming from system tray.

How are you sending the messages? The notification will only appear in the system tray if you are creating a Notification message (or mixed Notification and Data message) before sending.

The docs tell you which types of message goes to the tray and which are caught by the app's receiver, and some examples of Notification vs Data messages.

Example of Notification message

var message = {
  notification: {
    title: '$GOOG up 1.43% on the day',
    body: '$GOOG gained 11.80 points to close at 835.67, up 1.43% on the day.',
  },
  android: {
    ttl: 3600 * 1000,
    notification: {
      icon: 'stock_ticker_update',
      color: '#f45342',
    },
  }
}

Example of Data message

var message = {
  data: {
    title: '$GOOG up 1.43% on the day',
    body: '$GOOG gained 11.80 points to close at 835.67, up 1.43% on the day.',
  },
  android: {
    ttl: 3600 * 1000,
    notification: {
      icon: 'stock_ticker_update',
      color: '#f45342',
    },
  }
}

If you're using cloud functions to send messages, take a look at this reference document that outlines all parameters you can use to build messages.
