react-native-geolocation-service

React native geolocation service for iOS and android.

Why ?

This library is created in an attempt to fix the location timeout issue on android with the react-native's current implementation of Geolocation API. This library tries to solve the issue by using Google Play Service's new FusedLocationProviderClient API, which Google strongly recommends over android's default framework location API. It automatically decides which provider to use based on your request configuration and also prompts you to change the location mode if it doesn't satisfy your current request configuration.

NOTE: Location request can still timeout since many android devices have GPS issue in the hardware level or in the system software level. Check the FAQ for more details.

Installation

yarn add react-native-geolocation-service

Compatibility

RN Version	Package Version
0.57+	2.0.0
<0.57	1.1.0

Setup

iOS

No additional setup is required, since it uses the React Native's default Geolocation API. Just follow the React Native documentation to modify the .plist file.

Android

In android/app/build.gradle

...
dependencies {
    ...
    compile project(':react-native-geolocation-service')
}

If you've defined project-wide properties (recommended) in your root build.gradle, this library will detect the presence of the following properties:

buildscript {...}
allprojects {...}

/**
 + Project-wide Gradle configuration properties
 */
ext {
    compileSdkVersion   = 25
    targetSdkVersion    = 25
    buildToolsVersion   = "25.0.2"
    supportLibVersion   = "25.0.1"
    googlePlayServicesVersion = "11.0.0"
}

If you do not have project-wide properties defined and have a different play-services version than the one included in this library, use the following instead. But play service version should be 11+ or the library won't work.

...
dependencies {
    ...
    compile(project(':react-native-geolocation-service')) {
        exclude group: 'com.google.android.gms', module: 'play-services-location'
    }
    compile 'com.google.android.gms:play-services-location:<insert your play service version here>'
}

In android/setting.gradle

...
include ':react-native-geolocation-service'
project(':react-native-geolocation-service').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-geolocation-service/android')

In MainApplication.java

...
import com.agontuk.RNFusedLocation.RNFusedLocationPackage;

public class MainApplication extends Application implements ReactApplication {
    ...
    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
            ...
            new RNFusedLocationPackage()
        );
    }
}

Usage

Since this library was meant to be a drop-in replacement for the RN's Geolocation API, the usage is pretty straight forward, with some extra error cases to handle.

One thing to note, this library assumes that location permission is already granted by the user, so you have to use PermissionsAndroid to request for permission before making the location request.

...
import Geolocation from 'react-native-geolocation-service';
...

componentDidMount() {
    // Instead of navigator.geolocation, just use Geolocation.
    if (hasLocationPermission) {
        Geolocation.getCurrentPosition(
            (position) => {
                console.log(position);
            },
            (error) => {
                // See error code charts below.
                console.log(error.code, error.message);
            },
            { enableHighAccuracy: true, timeout: 15000, maximumAge: 10000 }
        );
    }
}

API

`getCurrentPosition(successCallback, ?errorCallback, ?options)`

successCallback: Invoked with latest location info.
errorCallback: Invoked whenever an error is encountered.

options:

Name	Type	Default	Description
timeout	`ms`	--	Request timeout
maximumAge	`ms`	`INFINITY`	How long previous location will be cached
enableHighAccuracy	`bool`	`false`	Use high accuracy mode
distanceFilter	`m`	`0`	Minimum displacement in meters
showLocationDialog	`bool`	`true`	whether to ask to enable location in Android

`watchPosition(successCallback, ?errorCallback, ?options)`

successCallback: Invoked with latest location info.
errorCallback: Invoked whenever an error is encountered.

options:

Name	Type	Default	Description
enableHighAccuracy	`bool`	`false`	Use high accuracy mode
distanceFilter	`m`	`100`	Minimum displacement between location updates in meters
interval	`ms`	`10000`	Interval for active location updates
fastestInterval	`ms`	`5000`	Fastest rate at which your application will receive location updates, which might be faster than `interval` in some situations (for example, if other applications are triggering location updates)
showLocationDialog	`bool`	`true`	whether to ask to enable location in Android

`clearWatch(watchId)`

watchId (id returned by watchPosition)

Checkout React Native documentation to see the list of available methods.

Error Codes

Name	Code	Description
PERMISSION_DENIED	1	Location permission is not granted
POSITION_UNAVAILABLE	2	Unable to determine position (not used yet)
TIMEOUT	3	Location request timed out
PLAY_SERVICE_NOT_AVAILABLE	4	Google play service is not installed or has an older version
SETTINGS_NOT_SATISFIED	5	Location service is not enabled or location mode is not appropriate for the current request
INTERNAL_ERROR	-1	Library crashed for some reason or the `getCurrentActivity()` returned null

TODO

Implement watchPosition & clearWatch methods for android
Implement stopObserving method for android

FAQ

Location timeout still happening ?

Try the following steps: (Taken from here)
- Turn phone off/on
- Turn GPS off/on
- Disable any battery saver settings, including Power Saving Mode, Battery Management or any third party apps
- Perform an "AGPS reset": Install the App GPS Status & Toolbox, then in that app, go to Menu > Tools > Manage A-GPS State > Reset
Adjusting battery saver settings on different devices:
- HTC: Access your phone settings > battery > power saving mode > battery optimization > select your app > don't optimize > save
- Huawei: Turn Energy Settings to Normal and add your app to "Protected Apps"
- LG If you're running Android 6 or higher: Settings > battery & power saving > battery usage > ignore optimizations > turn ON for your app
- Motorola If you're running Android 6 or higher: Battery > select the menu in the upper right-hand corner > battery optimization > not optimized > all apps > select your app > don't optimize
- OnePlus (using OxygenOS Settings): Battery > battery optimization > switch to 'all apps' > select your app > don't optimize
- Samsung: Access battery settings > app power saving > details > your app > disabled
- Sony If you're running Android 6 or higher: Battery > from the menu in the upper right-hand corner > battery optimization > apps > your app
- Xiaomi (MIUI OS) If you're running Android 6 or higher: Access your phone settings > additional settings > battery and performance > manage battery usage > apps > your app
