Cordova Geofence Plugin
Plugin to monitor circular geofences using mobile devices. The purpose is to notify user if crossing the boundary of the monitored geofence.
Geofences persists after device reboot. You do not have to open your app first to monitor added geofences
##Example application
Check out our example application built with ionic framework.
Installation
From master
cordova plugin add https://github.com/cowbell/cordova-plugin-geofence
Latest stable version
cordova plugin add 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 onTransitionReceived method
window.geofence.onTransitionReceived(geofences)
Constants
TransitionType.ENTER
= 1TransitionType.EXIT
= 2TransitionType.BOTH
= 3
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, 3 - Both
notification: { //Notification object
id: Number, //optional should be integer, id of notification
title: String, //Title of notification
text: String, //Text of notification
smallIcon: String, //Small icon showed in notification area, only res URI
icon: String, //icon showed in notification drawer
openAppOnClick: Boolean,//is main app activity should be opened after clicking on notification
vibration: [Integer], //Optional vibration pattern - see description
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
.
Notification vibrations
You can set vibration pattern for the notification or disable default vibrations.
To change vibration pattern set vibrate
property of notification
object in geofence.
###Examples
//disable vibrations
notification: {
vibrate: [0]
}
//Vibrate for 1 sec
//Wait for 0.5 sec
//Vibrate for 2 sec
notification: {
vibrate: [1000, 500, 2000]
}
###Platform quirks
Fully working only on Android.
On iOS vibration pattern doesn't work. Plugin only allow to vibrate with default system pattern.
Windows Phone - current status is TODO
Notification icons
To set notification icons use icon
and smallIcon
property in notification
object.
As a value you can enter:
- name of native resource or your application resource e.g.
res://ic_menu_mylocation
,res://icon
,res://ic_menu_call
- relative path to file in
www
directory e.g.file://img/ionic.png
smallIcon
- supports only resources URI
###Examples
notification: {
smallIcon: 'res://my_location_icon',
icon: 'file://img/geofence.png'
}
###Platform quirks
Works only on Android platform so far.
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.onTransitionReceived = function (geofences) {
geofences.forEach(function (geo) {
console.log('Geofence transition detected', geo);
});
};
When the app is opened via Notification click
Android, iOS only
window.geofence.onNotificationClicked = function (notificationData) {
console.log('App opened from Geo Notification!', notificationData);
};
#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: TransitionType.ENTER,
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
##iOS
Plugin is written in Swift. All xcode project options to enable swift support are set up automatically after plugin is installed.
##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>
