Cordova Badge Plugin
  

[Cordova][cordova] plugin to access and modify the badge number of the app icon on various mobile platforms including iOS and Android.

$3

Users see notifications in the following ways:

- Badging the app’s icon
- Progress indicator

$3

- Android / Amazon FireOS (via [ShortcutBadger][shortcut_badger])
- iOS 10+

Installation

The plugin can be installed via [Cordova-CLI][cli] and is publicly available on [NPM][npm].

Execute from the projects root folder:

$ cordova plugin add cordova-plugin-badge

Or install a specific version:

$ cordova plugin add cordova-plugin-badge@VERSION

Or install the latest head version:

$ cordova plugin add https://github.com/katzer/cordova-plugin-badge.git

Or install from local source:

$ cordova plugin add --nofetch --nosave

Usage

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

``js
document.addEventListener(
"deviceready",
function () {
// cordova.plugins.notification.badge is now available
},
false
);
`

$3

Badge numbers cannot be negative. The maximum might be restricted by the OS.
A callback is optional and will be invoked with the current badge number.

`js
cordova.plugins.notification.badge.set(10);
`



    



There's built-in support to increase the badge number:

`js
cordova.plugins.notification.badge.increase(1, function (badge) {
// badge is now 11 (10 + 1)
});
`

To decrease the badge number:

`js
cordova.plugins.notification.badge.decrease(2, function (badge) {
// badge is now 9 (11 - 2)
});
`

And to clear out the badge number:

`js
cordova.plugins.notification.badge.clear();
`

$3

The default value is 0. The badge number wont get lost after reboot or app restart.

`js
cordova.plugins.notification.badge.get(function (badge) {
...
});
`

Note: Modifying the badge number outside of the plugin does result into wrong behaivor!

$3

To clear the badge number automatically if the user taps the app icon:

`js
cordova.plugins.notification.badge.configure({ autoClear: true });
`

Permissions

The plugin might ask for granting permissions to modify the badge number.
That's done automatically but it's also possible to request them manually:

`javascript
cordova.plugins.notification.badge.requestPermission(function (granted) {
...
});
`





To check if they have been granted already:

`javascript
cordova.plugins.notification.badge.hasPermission(function (granted) {
...
});
`

Quirks

On Android not all launchers support badges. In order to set badges the plugin uses [ShortcutBadger][shortcut_badger]. Check out their website to see which launchers are supported.

If you're using PhoneGap Build please make sure you specify gradle as your Android build tool in config.xml:

`xml

`

To specify a custom version of _ShortcutBadger_ follow this [guide][gradle-guide]. The name of the property is appShortcutBadgerVersion.

`gradle


In /platforms/android/gradle.properties


appShortcutBadgerVersion=1.1.22
`
