NativeScript Local Notifications Plugin with custom sounds for android

The Local Notifications plugin allows your app to show notifications when the app is not running. Just like remote push notifications, but a few orders of magnitude easier to set up.

For Custom sound, Add a folder called 'raw' in /app/App_Resources/Android and add your custom sounds.

Note

This repository is a fork of the local notifications plugin by Eddy Verbruggen (eddyverbruggen). So big thanks to Eddy Verbruggen - Team Obsessive.

Installation

From the command prompt go to your app's root folder and execute:

tns plugin add nativescript-custom-local-notifications

schedule

On iOS you need to ask permission to schedule a notification. You can have the schedule funtion do that for you automatically (the notification will be scheduled in case the user granted permission), or you can manually invoke requestPermission if that's your thing.

You can pass several options to this function, everything is optional:

LocalNotifications.schedule([{
    id: 1,
    title: 'The first title',
    body: 'The first  body',
    ticker: 'The ticker',
    badge: 1,
    sound: "sound1", //sound1 from /Appresources/raw/ folder
    at: new Date(new Date().getTime() + (20 * 1000)) 
  }]).then(
      function() {
        console.log("Notification scheduled 1");
      },
      function(error) {
        console.log("scheduling error: " + error);
      }
  );

  LocalNotifications.schedule([{
    id: 1,
    title: 'The title',
    body: 'The body',
    ticker: 'The ticker',
    badge: 1,
    sound: null, // suppress sound on Android
    at: new Date(new Date().getTime() + (10 * 1000)) // 10 seconds from now
  }]).then(
      function() {
        console.log("Notification scheduled");
      },
      function(error) {
        console.log("scheduling error: " + error);
      }
  )

addOnMessageReceivedCallback

Tapping a notification in the notification center will launch your app. But what if you scheduled two notifications and you want to know which one the user tapped?

Use this function to have a callback invoked when a notification was used to launch your app. Note that on iOS it will even be triggered when your app is in the foreground and a notification is received.

  LocalNotifications.addOnMessageReceivedCallback(
      function (notification) {
        console.log("ID: " + notification.id);
        console.log("Title: " + notification.title);
        console.log("Body: " + notification.body);
      }
  ).then(
      function() {
        console.log("Listener added");
      }
  )

getScheduledIds

If you want to know the ID's of all notifications which have been scheduled, do this:

Note that all functions have an error handler as well (see schedule), but to keep things readable we won't repeat ourselves.

  LocalNotifications.getScheduledIds().then(
      function(ids) {
        console.log("ID's: " + ids);
      }
  )

cancel

If you want to cancel a previously scheduled notification (and you know its ID), you can cancel it:

  LocalNotifications.cancel(5 /* the ID */).then(
      function(foundAndCanceled) {
          if (foundAndCanceled) {
            console.log("OK, it's gone!");
          } else {
            console.log("No ID 5 was scheduled");
          }
      }
  )

cancelAll

If you just want to cancel all previously scheduled notifications, do this:

  LocalNotifications.cancelAll();

requestPermission

On Android you don't need permission, but on iOS you do. Android will simply return true.

If the requestPermission or schedule function previously ran the user has already been prompted to grant permission. If the user granted permission this function returns true, but if he denied permission this function will return false, since an iOS can only request permission once. In which case the user needs to go to the iOS settings app and manually enable permissions for your app.

  LocalNotifications.requestPermission().then(
      function(granted) {
        console.log("Permission granted? " + granted);
      }
  )

hasPermission

On Android you don't need permission, but on iOS you do. Android will simply return true.

If the requestPermission or schedule functions previously ran you may want to check whether or not the user granted permission:

  LocalNotifications.hasPermission().then(
      function(granted) {
        console.log("Permission granted? " + granted);
      }
  )
