How to know if the app is open from the android notification tray?

Question

How to know if the app is open from the android notification tray? For instance, I have closed the app (cleared from recent app list). but I receive notification from the backend websocket, i pressed it, it opens the app. So my question is, is there way to check if this is open from notification?

Answer 1

Its simple, you receive notifications payload in your push notification listener

import PushNotification from 'react-native-push-notification'
configurePushNotifications = () => {

    PushNotification.configure({
      // (optional) Called when Token is generated (iOS and Android)
      onRegister: function(token) {
        console.log('PushNotification token', token)
      },

onNotification is where you would receive you local or remote notification and it will be called when the user clicks on notification tray

      onNotification: function(notification) {
        console.log('notification received', notification)
      },

      // IOS ONLY (optional): default: all - Permissions to register.
      permissions: {
        alert: true,
        badge: true,
        sound: true,
      },

      // Should the initial notification be popped automatically
      // default: true
      popInitialNotification: true,

      /**
       * (optional) default: true
       * - Specified if permissions (ios) and token (android and ios) will requested or not,
       * - if not, you must call PushNotificationsHandler.requestPermissions() later
       */
      requestPermissions: true,
    })
  }

this is how the notificaion object would look like

{
    foreground: false, // BOOLEAN: If the notification was received in foreground or not
    userInteraction: false, // BOOLEAN: If the notification was opened by the user from the notification area or not
    message: 'My Notification Message', // STRING: The notification message
    data: {}, // OBJECT: The push data
}
