Npm package is now @mauron85/cordova-plugin-background-geolocation!
Please support my work and continued development with your donation.
All new issues should follow instructions in ISSUE_TEMPLATE.md.
A properly filled issue report will significantly reduce number of follow up questions and decrease issue resolving time.
Most issues cannot be resolved without debug logs. Please try to isolate debug lines related to your issue.
Instructions for how to prepare debug logs can be found in section Debugging.
If you're reporting an app crash, debug logs might not contain all the necessary information about the cause of the crash.
In that case, also provide relevant parts of output of adb logcat command.
There are repeatedly reported issues with some android devices not working in the background. Check if your device model is on dontkillmyapp list before you report new issue. For more information check out dontkillmyapp.com.
Another confusing fact about Android services is concept of foreground services. Foreground service in context of Android OS is different thing than background geolocation service of this plugin (they're related thought). Plugin's background geolocation service actually becomes foreground service when app is in the background. Confusing, right? :D
If service wants to continue to run in the background, it must "promote" itself to foreground service. Foreground services must have visible notification, which is the reason, why you can't disable drawer notification.
The notification can only be disabled, when app is running in the foreground, by setting config option startForeground: false (this is the default option), but will always be visible in the background (if service was started).

Cross-platform geolocation for Cordova / PhoneGap with battery-saving "circular region monitoring" and "stop detection".
This plugin can be used for geolocation when the app is running in the foreground or background. It is more battery and data efficient than html5 geolocation or cordova-geolocation plugin. It can be used side by side with other geolocation providers (eg. html5 navigator.geolocation).
You can choose from two location location providers:
- DISTANCE_FILTER_PROVIDER
- ACTIVITY_PROVIDER
- RAW_PROVIDER
See Which provider should I use? for more information about providers.
Checkout repository cordova-plugin-background-geolocation-example.
See MIGRATIONS.md
cordova plugin add @mauron85/cordova-plugin-background-geolocation
You may also want to change default iOS permission prompts and set specific google play version and android support library version for compatibility with other plugins.
Note: Always consult documentation of other plugins to figure out compatible versions.
cordova plugin add @mauron85/cordova-plugin-background-geolocation \
--variable GOOGLE_PLAY_SERVICES_VERSION=11+ \
--variable ANDROID_SUPPORT_LIBRARY_VERSION=23+ \
--variable ALWAYS_USAGE_DESCRIPTION="App requires ..." \
--variable MOTION_USAGE_DESCRIPTION="App requires motion detection"
Or in config.xml:
<plugin name="cordova-plugin-background-geolocation" spec="@mauron85/cordova-plugin-background-geolocation@~3.1.0">
<variable name="GOOGLE_PLAY_SERVICES_VERSION" value="11+" />
<variable name="ANDROID_SUPPORT_LIBRARY_VERSION" value="26+" />
<variable name="ICON" value="@mipmap/icon" />
<variable name="SMALL_ICON" value="@mipmap/icon" />
<variable name="ALWAYS_USAGE_DESCRIPTION" value="App requires background tracking " />
<variable name="MOTION_USAGE_DESCRIPTION" value="App requires motion detection" />
</plugin>
Note: To apply changes, you must remove and reinstall plugin.
This plugin should work with Adobe® PhoneGap™ Build without any modification.
To register plugin add following line into your config.xml:
<plugin name="@mauron85/cordova-plugin-background-geolocation"/>
Note: If you're using hydration, you have to download and reinstall your app with every new version of the plugin, as plugins are not updated.
| Plugin version | Cordova CLI | Cordova Platform Android | Cordova Platform iOS |
|---|---|---|---|
| <2.3.0 | 6.4.0 | 6.3.0 | 4.4.0 |
| >=2.3.0 | 7.1.0 | 6.3.0 | 4.4.0 |
Please note that as of Cordova Android 6.0.0 icons are by default in mipmap/ directory not drawable/ directory, so this plugin will have a build issue on < 6.0.0 Cordova builds, you will need to update Authenticator.xml to drawable directory from mipmap directory to work on older versions.
You will need to ensure that you have installed the following items through the Android SDK Manager:
| Name | Version |
|---|---|
| Android SDK Tools | 26.0.2 |
| Android SDK Platform-tools | 26.0.2 |
| Android SDK Build-tools | 26.0.2 |
| Android Support Repository | 47 |
| Android Support Library | 26.1.0 |
| Google Play Services | 11.8.0 |
| Google Repository | 58 |
Android is no longer supporting downloading support libraries through the SDK Manager. The support libraries are now available through Google's Maven repository.

Partial reconfiguration is possible by later providing a subset of the configuration options:
BackgroundGeolocation.configure({
debug: true
});
In this case new configuration options will be merged with stored configuration options and changes will be applied immediately.
Important: Because configuration options are applied partially, it's not possible to reset option to default value just by omitting it's key name and calling configure method. To reset configuration option to the default value, it's key must be set to null!
// Example: reset postTemplate to default
BackgroundGeolocation.configure({
postTemplate: null
});
Platform: iOS, Android
Get current configuration. Method will return all configuration options and their values in success callback.
Because configure method can be called with subset of the configuration options only,
getConfig method can be used to check the actual applied configuration.
BackgroundGeolocation.getConfig(function(config) {
console.log(config);
});
Platform: iOS, Android
Start background geolocation.
Platform: iOS, Android
Stop background geolocation.

authorization |
Number |
authorization status |
Authorization statuses:
- NOT_AUTHORIZED
- AUTHORIZED - authorization to run in background and foreground
- AUTHORIZED_FOREGROUND iOS only authorization to run in foreground only
Note: In the Android concept of authorization, these represent application permissions.
Platform: Android >= 6, iOS >= 8.0
Show app settings to allow change of app location permissions.
Platform: Android
Show system settings to allow configuration of current location sources.
Platform: iOS, Android
Method will return all stored locations. This method is useful for initial rendering of user location on a map just after application launch.
| Success callback parameter | Type | Description |
|---|---|---|
locations |
Array |
collection of stored locations |
BackgroundGeolocation.getLocations(
function (locations) {
console.log(locations);
}
);Platform: iOS, Android
Method will return locations which have not yet been posted to server.
| Success callback parameter | Type | Description |
|---|---|---|
locations |
Array |
collection of stored locations |
Platform: iOS, Android
Delete location with locationId.
Note: You don't need to delete all locations. The plugin manages the number of stored locations automatically and the total count never exceeds the number as defined by option.maxLocations.
Platform: iOS, Android
Delete all stored locations.
Note: Locations are not actually deleted from database to avoid gaps in locationId numbering.
Instead locations are marked as deleted. Locations marked as deleted will not appear in output of BackgroundGeolocation.getValidLocations.
Platform: iOS
Normally the plugin will handle switching between BACKGROUND and FOREGROUND mode itself. Calling switchMode you can override plugin behavior and force it to switch into other mode.
In FOREGROUND mode the plugin uses iOS local manager to receive locations and behavior is affected
by option.desiredAccuracy and option.distanceFilter.
In BACKGROUND mode plugin uses significant changes and region monitoring to receive locations
and uses option.stationaryRadius only.
// switch to FOREGROUND mode
BackgroundGeolocation.switchMode(BackgroundGeolocation.FOREGROUND_MODE);
// switch to BACKGROUND mode
BackgroundGeolocation.switchMode(BackgroundGeolocation.BACKGROUND_MODE);
Platform: Android, iOS
Force sync of pending locations. Option syncThreshold will be ignored and
all pending locations will be immediately posted to syncUrl in single batch.

Event listeners can registered with:
const eventSubscription = BackgroundGeolocation.on('event', callbackFn);
And unregistered:
eventSubscription.remove();
Note: Components should unregister all event listeners in componentWillUnmount method,
individually, or with removeAllListeners
All locations updates are recorded in the local db at all times. When the App is in foreground or background, in addition to storing location in local db,
the location callback function is triggered. The number of locations stored in db is limited by option.maxLocations and never exceeds this number.
Instead, old locations are replaced by new ones.
When option.url is defined, each location is also immediately posted to url defined by option.url.
If the post is successful, the location is marked as deleted in local db.
When option.syncUrl is defined, all locations that fail to post locations will be coalesced and sent in some time later in a one single batch.
Batch sync takes place only when the number of failed-to-post locations reaches option.syncTreshold.
Locations are sent only in single batch, when the number of locations reaches option.syncTreshold. (No individual locations will be sent)
The request body of posted locations is always an array, even when only one location is sent.
Warning: option.maxLocations has to be larger than option.syncThreshold. It's recommended to be 2x larger. In any other case the location syncing might not work properly.
With option.postTemplate it is possible to specify which location properties should be posted to option.url or option.syncUrl. This can be useful to reduce
the number of bytes sent "over the wire".
All wanted location properties have to be prefixed with @. For all available properties check Location event.
Two forms are supported:
jsonObject
BackgroundGeolocation.configure({
postTemplate: {
lat: '@latitude',
lon: '@longitude',
foo: 'bar' // you can also add your own properties
}
});
jsonArray
BackgroundGeolocation.configure({
postTemplate: ['@latitude', '@longitude', 'foo', 'bar']
});
Note: Keep in mind that all locations (even a single one) will be sent as an array of object(s), when postTemplate is jsonObject and array of array(s) for jsonArray!
A special task that gets executed when the app is terminated, but the plugin was configured to continue running in the background (option stopOnTerminate: false).
In this scenario the Activity
was killed by the system and all registered event listeners will not be triggered until the app is relaunched.
Note: Prefer configuration options url and syncUrl over headless task. Use it sparingly!
| Parameter | Type | Description |
|---|---|---|
event.name |
String |
Name of the event [ "location", "stationary", "activity" ] |
event.params |
Object |
Event parameters. @see Events |
Keep in mind that the callback function lives in an isolated scope. Variables from a higher scope cannot be referenced!
Following example requires CORS enabled backend server.
BackgroundGeolocation.headlessTask(function(event) {
if (event.name === 'location' ||
event.name === 'stationary') {
var xhr = new XMLHttpRequest();
xhr.open('POST', 'http://192.168.81.14:3000/headless');
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.send(JSON.stringify(event.params));
}
return 'Processing event: ' + event.name; // will be logged
});
Background-geolocation-server is a backend server written in nodejs with CORS - Cross-Origin Resource Sharing support. There are instructions how to run it and simulate locations on Android, iOS Simulator and Genymotion.
On iOS the plugin will execute your registered .on('location', callbackFn) callback function. You may manually POST the received Geolocation to your server using standard XHR. However for long running tasks, you need
to wrap your code in startTask - endTask block.
The plugin uses iOS Significant Changes API, and starts triggering callbackFn only when a cell-tower switch is detected (i.e. the device exits stationary radius). The function switchMode is provided to force the plugin to enter "BACKGROUND" stationary or "FOREGROUND" mode.
Plugin cannot detect the exact moment the device moves out of the stationary-radius. In normal conditions, it can take as much as 3 city-blocks to 1/2 km before stationary-region exit is detected.
On Android devices it is recommended to have a notification in the drawer (option startForeground:true). This gives plugin location service higher priority, decreasing probability of OS killing it. Check wiki for explanation.
Plugin should work with custom ROMS at least DISTANCE_FILTER_PROVIDER. But ACTIVITY_PROVIDER provider depends on Google Play Services. Usually ROMs don't include Google Play Services libraries. Strange bugs may occur, like no GPS locations (only from network and passive) and other. When posting issue report, please mention that you're using custom ROM.
Note: Following section was kindly copied from phonegap-plugin-push. Visit link for resolving issue with facebook plugin.
If you have an issue compiling the app and you're getting an error similar to this (com.android.dex.DexException: Multiple dex files define):

Then at least one other plugin you have installed is using an outdated way to declare dependencies such as android-support or play-services-gcm.
This causes gradle to fail, and you'll need to identify which plugin is causing it and request an update to the plugin author, so that it uses the proper way to declare dependencies for cordova.
See this for the reference on the cordova plugin specification, it'll be usefull to mention it when creating an issue or requesting that plugin to be updated.
Common plugins to suffer from this outdated dependency management are plugins related to facebook, google+, notifications, crosswalk and google maps.
Android 6.0 "Marshmallow" introduced a new permissions model where the user can turn on and off permissions as necessary. When user disallow location access permissions, error configure callback will be called with error code: 2.
Note: Only available for API Level >=21.
To use custom notification icons, you need to put icons into res/drawable directory of your app. You can automate the process as part of after_platform_add hook configured via config.xml. Check config.xml and scripts/res_android.js of example app for reference.
If you only want a single large icon, set notificationIconLarge to null and include your icon's filename in the notificationIconSmall parameter.
With Adobe® PhoneGap™ Build icons must be placed into locales/android/drawable dir at the root of your project. For more information go to how-to-add-native-image-with-phonegap-build.
Plugin will not work in XDK emulator ('Unimplemented API Emulation: BackgroundGeolocation.start' in emulator). But will work on real device.
See DEBUGGING.md
There is nice cordova plugin cordova-plugin-geofence, which does exactly that. Let's keep this plugin lightweight as much as possible.
