# Cordova Geofence Plugin
[](https://badge.fury.io/js/cordova-plugin-geofence)
Plugin to monitor circular geofences using mobile devices. The purpose is to notify user if crossing the boundary of the monitored geofence.
*Geofences persist after device reboot. You do not have to open your app first to monitor added geofences*
## Example applications
Check out our example applications:
* https://github.com/cowbell/ionic-geofence built with [Ionic](http://ionic.io/) framework
* https://github.com/tsubik/ionic2-geofence built with [Ionic 2](http://ionic.io/2) framework
* https://github.com/cowbell/ember-geofence built with [Ember.js](http://emberjs.com/), [Cordova](https://cordova.apache.org/), [Material Design](https://www.google.com/design/spec/material-design/introduction.html)
## 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 cordova CLI
```
cordova plugin rm cordova-plugin-geofence
```
## Supported Platforms
- Android
- iOS >=7.0
- Windows Phone 8.1
- using Universal App (cordova windows platform)
- using Silverlight App (cordova wp8 platform retargeted to WP 8.1)
## Known Limitations
**This plugin is a wrapper on devices' native APIs** which mean it comes with **limitations of those APIs**.
### Geofence Limit
There are certain limits of geofences that you can set in your application depends on the platform of use.
- iOS - 20 geofences
- Android - 100 geofences
### Javascript background execution
This is known limitation. When in background your app may/will be suspended to not use system resources.
Therefore, **any javascript code won't run**, only background services can run in the background. Local
notification when user crosses a geofence region will still work, but any custom javascript code won't.
If you want to perform a custom action on geofence crossing, [try to write it in native code](#listening-for-geofence-transitions-in-native-code).
# Platform specifics
## Android
This plugin uses Google Play Services so you need to have it installed on your device.
## iOS
Plugin is written in Swift. All xcode project options to enable swift support are set up automatically after plugin is installed thanks to
[cordova-plugin-add-swift-support](https://github.com/akofman/cordova-plugin-add-swift-support).
:warning: Swift 3 is not supported at the moment, the following preference has to be added in your project :
For Cordova projects
``
For PhoneGap projects
``
### iOS Quirks
Since iOS 10 it's mandatory to add a `NSLocationAlwaysUsageDescription` and `NSLocationWhenInUseUsageDescription` entries in the info.plist.
`NSLocationWhenInUseUsageDescription` describes the reason that the app accesses the user's location.
`NSLocationAlwaysUsageDescription` describes the reason that the app accesses the user's location when not in use (in the background).
When the system prompts the user to allow access, this string is displayed as part of the dialog box. To add this entry you can pass the variable `GEOFENCE_IN_USE_USAGE_DESCRIPTION` and `GEOFENCE_ALWAYS_USAGE_DESCRIPTION` on plugin install.
Example:
`cordova plugin add cordova-plugin-geofence --variable GEOFENCE_IN_USE_USAGE_DESCRIPTION="your usage message" --variable GEOFENCE_ALWAYS_USAGE_DESCRIPTION="your usage message"`
If you don't pass the variable, the plugin will add a default string as value.
## 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
```xml
```
# Using the plugin
Cordova initialize plugin to `window.geofence` object.
## Methods
All methods returning promises, but you can also use standard callback functions.
- `window.geofence.initialize(onSuccess, onError)`
- `window.geofence.addOrUpdate(geofences, onSuccess, onError)`
- `window.geofence.remove(geofenceId, onSuccess, onError)`
- `window.geofence.removeAll(onSuccess, onError)`
- `window.geofence.getWatched(onSuccess, onError)`
For listening of geofence transistion you can override onTransitionReceived method
- `window.geofence.onTransitionReceived(geofences)`
## Constants
- `TransitionType.ENTER` = 1
- `TransitionType.EXIT` = 2
- `TransitionType.BOTH` = 3
## Error Codes
Both `onError` function handler and promise rejection take `error` object as an argument.
```
error: {
code: String,
message: String
}
```
Error codes:
- `UNKNOWN`
- `PERMISSION_DENIED`
- `GEOFENCE_NOT_AVAILABLE`
- `GEOFENCE_LIMIT_EXCEEDED`
## Plugin initialization
The plugin is not available until `deviceready` event is fired.
```javascript
document.addEventListener('deviceready', function () {
// window.geofence is now available
window.geofence.initialize().then(function () {
console.log("Successful initialization");
}, function (error) {
console.log("Error", error);
});
}, false);
```
Initialization process is responsible for requesting neccessary permissions.
If required permissions are not granted then initialization fails with error message.
## Adding new geofence to monitor
```javascript
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 (error) {
console.log('Adding geofence failed', error);
});
```
Adding more geofences at once
```javascript
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
```javascript
window.geofence.remove(geofenceId)
.then(function () {
console.log('Geofence sucessfully removed');
}
, function (error){
console.log('Removing geofence failed', error);
});
```
Removing more than one geofence at once.
```javascript
window.geofence.remove([geofenceId1, geofenceId2, geofenceId3]);
```
## Removing all geofences
```javascript
window.geofence.removeAll()
.then(function () {
console.log('All geofences successfully removed.');
}
, function (error) {
console.log('Removing geofences failed', error);
});
```
## Getting watched geofences from device
```javascript
window.geofence.getWatched().then(function (geofencesJson) {
var geofences = JSON.parse(geofencesJson);
});
```
## Listening for geofence transitions
```javascript
window.geofence.onTransitionReceived = function (geofences) {
geofences.forEach(function (geo) {
console.log('Geofence transition detected', geo);
});
};
```
## Listening for geofence transitions in native code
### Android
For android plugin broadcasting intent `com.cowbell.cordova.geofence.TRANSITION`. You can implement your own `BroadcastReceiver` and start listening for this intent.
Register receiver in `AndroidManifest.xml`
```xml
```
Example `TransitionReceiver.java` code
```java
......
import com.cowbell.cordova.geofence.Gson;
import com.cowbell.cordova.geofence.GeoNotification;
public class TransitionReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String error = intent.getStringExtra("error");
if (error != null) {
//handle error
Log.println(Log.ERROR, "YourAppTAG", error);
} else {
String geofencesJson = intent.getStringExtra("transitionData");
GeoNotification[] geoNotifications = Gson.get().fromJson(geofencesJson, GeoNotification[].class);
//handle geoNotifications objects
}
}
}
```
## When the app is opened via Notification click
Android, iOS only
```javascript
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
```javascript
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);
})
```
