From master

cordova plugin add https://github.com/cowbell/cordova-plugin-geofence

Removing the Plugin from project

Using the plugin

Cordova initialize plugin to window.geofence object.

Methods

• window.geofence.initialize(onSuccess, onError)
• window.geofence.addOrUpdate(geofences, onSuccess, onError)
• window.geofence.remove(onSuccess, onError)
• window.geofence.removeAll(onSuccess, onError)
• window.geofence.getWatched(onSuccess, onError)

All methods returning promises, but you can also use standard callback functions.

For listening of geofence transistion you can override recieveTransition method

• window.geofence.recieveTransition(geofences)

Plugin initialization

The plugin is not available until deviceready event is fired.

document.addEventListener('deviceready', function () {
    // window.geofence is now available
    window.geofence.initialize();
}, false);

Adding new geofence to monitor

window.geofence.addOrUpdate({
    id:             String, //A unique identifier of geofence
    latitude:       Number, //Geo latitude of geofence
    longitude:      Number, //Geo longitude of geofence
    radius:         Number, //Radius of geofence in meters
    transitionType: Number, //Type of transition 1 - Enter, 2 - Exit
    notification: {         //Notification object
        id:             Number, //optional should be integer, id of notidication
        title:          String, //Title of notification
        text:           String, //Text of notification
        openAppOnClick: Boolean,//is main app activity should be opened after clicking on notification
        data:           Object  //Custom object associated with notification
    }
}).then(function () {
    console.log('Geofence successfully added');
}, function (reason) {
    console.log('Adding geofence failed', reason);
});

Adding more geofences at once

window.geofence.addOrUpdate([geofence1, geofence2, geofence3]);

Geofence overrides the previously one with the same id.

All geofences are stored on the device and restored to monitor after device reboot.

Notification overrides the previously one with the same notification.id.

Removing

Removing single geofence

window.geofence.remove(geofenceId)
    .then(function () {
        console.log('Geofence sucessfully removed');
    }
    , function (reason){
        console.log('Removing geofence failed', reason);
    });

Removing more than one geofence at once.

window.geofence.remove([geofenceId1, geofenceId2, geofenceId3]);

Removing all geofences

window.geofence.removeAll()
    .then(function () { 
        console.log('All geofences successfully removed.');
    }
    , function (reason) {
        console.log('Removing geofences failed', reason);
    });

Getting watched geofences from device

window.geofence.getWatched().then(function (geofencesJson) {
    var geofences = JSON.parse(geofencesJson);
});

Listening for geofence transitions

window.geofence.recieveTransition = function (geofences) {
    geofences.forEach(function (geo) {
        console.log('Geofence transition detected', geo);
    });
};

#Example usage

Adding geofence to monitor entering Gliwice city center area of radius 3km

window.geofence.addOrUpdate({
    id:             "69ca1b88-6fbe-4e80-a4d4-ff4d3748acdb",
    latitude:       50.2980049, 
    longitude:      18.6593152, 
    radius:         3000, 
    transitionType: 1, 
    notification: {    
        id:             1,     
        title:          "Welcome in Gliwice", 
        text:           "You just arrived to Gliwice city center.",
        openAppOnClick: true
    }
}).then(function () {
    console.log('Geofence successfully added');
}, function (reason) {
    console.log('Adding geofence failed', reason);
})

Platform specifics

##Windows phone 8.1

Plugin can be used with both windows phone 8.1 type projects Univeral App, Silverlight App.

In order to use toast notifications you have to enable this feature in appxmanifest file either using UI in Visual Studio or edit file setting attribute ToastCapable="true" in m3:VisualElements node under Package/Applications/Application.

If you are retargeting WP 8.0 to WP 8.1 you need to register background task to perform geofence notifications. Register it via UI in Visual Studio or add following code under Package/Applications/Application/Extensions

<Extension Category="windows.backgroundTasks" EntryPoint="GeofenceComponent.GeofenceTrigger">
    <BackgroundTasks>
        <m2:Task Type="location" />
    </BackgroundTasks>
</Extension>
