A notification is a message you display to the user outside of your app's normal UI. When you tell the system to issue a notification, it first appears as an icon in the notification area. To see the details of the notification, the user opens the notification drawer. Both the notification area and the notification drawer are system-controlled areas that the user can view at any time.

Important Notice

Please make sure that you always read the tagged README for the version you're using.

Please report bugs or missing features.

Basics

The plugin creates the object cordova.plugins.notification.local and is accessible after deviceready has been fired.

cordova.plugins.notification.local.schedule({
    title: 'My first notification',
    text: 'Thats pretty easy...',
    foreground: true
});

The plugin allows to schedule multiple notifications at once.

cordova.plugins.notification.local.schedule([
    { id: 1, title: 'My first notification' },
    { id: 2, title: 'My first notification' }
]);

Properties

A notification does have a set of configurable properties.

<b>Not all of them are supported across all platforms.</b>

<i>The table is not complete regarding the support.</i>

For their default values see:

cordova.plugins.notification.local.getDefaults();

To change some default values:

cordova.plugins.notification.local.setDefaults({
    led: { color: '#FF00FF', on: 500, off: 500 },
    vibrate: false
});

Actions

The plugin knows two types of actions: button and input.

cordova.plugins.notification.local.schedule({
    title: 'The big survey',
    text: 'Are you a fan of RB Leipzig?',
    attachments: ['file://img/rb-leipzig.jpg'],
    actions: [
        { id: 'yes', title: 'Yes' },
        { id: 'no',  title: 'No' }
    ]
});

Icons on action buttons are not displayed anymore since Android 7, see documentation

Input

cordova.plugins.notification.local.schedule({
    title: 'Justin Rhyss',
    text: 'Do you want to go see a movie tonight?',
    actions: [{
        id: 'reply',
        type: 'input',
        title: 'Reply',
        emptyText: 'Type message',
    }, ... ]
});

It is recommended to pre-define action groups rather then specifying them with each new notification of the same type.

cordova.plugins.notification.local.addActions('yes-no', [
    { id: 'yes', title: 'Yes' },
    { id: 'no',  title: 'No'  }
]);

Once you have defined an action group, you can reference it when scheduling notifications:

cordova.plugins.notification.local.schedule({
    title: 'Justin Rhyss',
    text: 'Do you want to go see a movie tonight?',
    actions: 'yes-no'
});

Properties

Actions do have a set of configurable properties. Not all of them are supported across all platforms.

Triggers

Notifications may trigger immediately or depend on calendar or location.

To trigger at a fix date:

cordova.plugins.notification.local.schedule({
    title: 'Design team meeting',
    text: '3:00 - 4:00 PM',
    trigger: { at: new Date(2017, 10, 27, 15) }
});

Or relative from now:

cordova.plugins.notification.local.schedule({
    title: 'Design team meeting',
    trigger: { in: 1, unit: 'hour' }
});

Repeating

Repeat relative from now:

cordova.plugins.notification.local.schedule({
    title: 'Design team meeting',
    trigger: { every: 'day', count: 5 }
});

Or trigger every time the date matches:

cordova.plugins.notification.local.schedule({
    title: 'Happy Birthday!!!',
    trigger: { every: { month: 10, day: 27, hour: 9, minute: 0 } }
});

Location based

To trigger when the user enters a region:

cordova.plugins.notification.local.schedule({
    title: 'Welcome to our office',
    trigger: {
        type: 'location',
        center: [x, y],
        radius: 15,
        notifyOnEntry: true
    }
});

Properties

The properties depend on the trigger type. Not all of them are supported across all platforms.

Progress

Notifications can include an animated progress indicator that shows users the status of an ongoing operation. Android only.

cordova.plugins.notification.local.schedule({
    title: 'Sync in progress',
    text: 'Copied 2 of 10 files',
    progressBar: { value: 20 }
});

Patterns

Split the text by line breaks if the message comes from a single person and just too long to show in a single line.

cordova.plugins.notification.local.schedule({
    title: 'The Big Meeting',
    text: '4:15 - 5:15 PM\nBig Conference Room',
    smallIcon: 'res://calendar',
    icon: 'https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTzfXKe6Yfjr6rCtR6cMPJB8CqMAYWECDtDqH-eMnerHHuXv9egrw'
});

Summarizing

Instead of displaying multiple notifications, you can create one notification that summarizes them all.

cordova.plugins.notification.local.schedule({
    id: 15,
    title: 'Chat with Irish',
    icon: 'http://climberindonesia.com/assets/icon/ionicons-2.0.1/png/512/android-chat.png',
    text: [
        { message: 'I miss you' },
        { person: 'Irish', message: 'I miss you more!' },
        { message: 'I always miss you more by 10%' }
    ]
});

To add a new message to the existing chat:

cordova.plugins.notification.local.update({
    id: 15,
    text: [{ person: 'Irish', message: 'Bye bye' }]
});

Grouping

Your app can present multiple notifications as a single group:

• A parent notification displays a summary of its child notifications.
• The child notifications are presented without duplicate header information.

cordova.plugins.notification.local.schedule([
    { id: 0, title: 'Design team meeting', ... },
    { id: 1, summary: 'me@gmail.com', group: 'email', groupSummary: true },
    { id: 2, title: 'Please take all my money', ... group: 'email' },
    { id: 3, title: 'A question regarding this plugin', ... group: 'email' },
    { id: 4, title: 'Wellcome back home', ... group: 'email' }
]);

Permissions

Each platform may require the user to grant permissions first before the app is allowed to schedule notifications.

cordova.plugins.notification.local.hasPermission(function (granted) { ... });

If requesting via plug-in, a system dialog does pop up for the first time. Later its only possible to tweak the settings through the system settings.

cordova.plugins.notification.local.requestPermission(function (granted) { ... });

Checking the permissions is done automatically, however it's possible to skip that.

cordova.plugins.notification.local.schedule(toast, callback, scope, { skipPermission: true });

Events

The following events are supported: add, trigger, click, clear, cancel, update, clearall and cancelall.

cordova.plugins.notification.local.on(event, callback, scope);

To unsubscribe from events:

cordova.plugins.notification.local.un(event, callback, scope);

Note: You have to provide the exact same callback to cordova.plugins.notification.local.un as you provided to cordova.plugins.notification.local.on to make unsubscribing work. Hence you should define your callback as a separate function, not inline. If you want to use this inside of your callback, you also have to provide this as scope to cordova.plugins.notification.local.on.

Custom

The plugin also fires events specified by actions.

cordova.plugins.notification.local.schedule({
    title: 'Do you want to go see a movie tonight?',
    actions: [{ id: 'yes', title: 'Yes' }]
});

The name of the event is the id of the action.

cordova.plugins.notification.local.on('yes', function (notification, eopts) { ... });

Fire manually

Not an official interface, however its possible to manually fire events.

cordova.plugins.notification.local.core.fireEvent(event, args);

Launch Details

Check the launchDetails to find out if the app was launched by clicking on a notification.

document.addEventListener('deviceready', function () {
    console.log(cordova.plugins.notification.local.launchDetails);
}, false);

It might be possible that the underlying framework like Ionic is not compatible with the launch process defined by cordova. With the result that the plugin fires the click event on app start before the app is able to listen for the events.

Therefore its possible to fire the queued events manually by defining a global variable.

window.skipLocalNotificationReady = true

Once the app and Ionic is ready, you can fire the queued events manually.

cordova.plugins.notification.local.fireQueuedEvents();

Methods

All methods work asynchronous and accept callback methods. See the sample app for how to use them.

Android exact/inexact Alarms

Since Android 13 notifications will be scheduled inexact by default. The user must grant exact alarm permissions manually in the "Alarms & Reminders"-setting by openAlarmSettings, if exact alarms are required.

openAlarmSettings

Opens the "Alarms & Reminders"-settings as an Activity when running on Android 12 (SDK 31) or later, where the user can enable exact alarms. On Android older then 12, it will just call the successCallback, without doing anything. This method will not wait for the user to be returned back to the app. For this, the resume-event can be used. The callback will just return OK, after starting the activity.

• If the user grants permission, already inexact scheduled notifications will automatically be rescheduled as exact alarms, but only if the app is still available in background.
• If exact alarms were already granted and the user revokes it, the app will be killed and all scheduled notifications will be canceld. The app have to schedule the notifications as inexact alarms again, when the app is opened the next time, see https://developer.android.com/develop/background-work/services/alarms/schedule#using-schedule-exact-permission.

canScheduleExactAlarms

Checks if the user has enabled the "Alarms & Reminders"-setting. If not, the notificiatons will be scheduled inexact, which is still ok and will only be delayed by some minutes.

• On Android 12 the permission is granted by default
• On Android 13 and newer, the permission is not granted by default and have to be explicitly enabled by the user.
• On Android 11 and older, this method will always return true in the successCallback.

openNotificationSettings

Opens the notifications settings of the app on Android 8 and newer. This method will not wait for the user to be returned back to the app. For this, the resume-event can be used.

• On Android, the callback will just return "OK", after starting the activity.
• On Android older then 8, it opens the app details.
• On iOS it's not possible to open the notification settings, it will open the app settings.

Android Notification Channels

Since Android 8 notification channels must be created to post noitifications. The settings for the vibration, sound and importance is set by a channel and not by a notification. A channel is not changeable, after it is created. This is a restriction by Android.

Default Channel

A default channel will always be created by this plugin and has the following settings:

• ID: default-channel-id
• Name: Default channel
• IMPORTANCE_DEFAULT

The values of the default channel are not configurable at this point. Any notification that doesn't specify a channelId property will use this default channel with default sound and vibration settings.

The creation of a channel is done as follows:

cordova.plugins.notification.local.createChannel({
    channelId:'my_ch_id', // string - To separate something in the id, use "_" instead of "-"
    channelName:'My Channel Name', // string 
    description:"Description of channel", // string (optional)
    sound: 'file://audio/ring.mp3', // string (optional) 
    vibrate: true, // bool (optional), default is false
    importance: 3, // int (optional) 0 to 4, default is IMPORTANCE_DEFAULT (3)
    soundUsage: 5, // int (optional), default is USAGE_NOTIFICATION
  }, success_callback, this)

For setting the channel, use the channelId property when scheduling a notification.

Notes

Android

Device reboot

When the device reboots, all notifications will be rescheduled by the plugin, because Android cancels all alarams after a device reboot. If the user has set up a device lock, this must first be unlocked for the notifications to be rescheduled.
