nunlup-services-geolocation

React native geolocation service for iOS and android.

Fork

This package is a fork from: https://github.com/Agontuk/react-native-geolocation-service

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

yarn add nunlup-services-geolocation

npm

npm install nunlup-services-geolocation

Compatibility

| RN Version | Package Version | | ---------- | --------------- | | 0.57+ | 2.0.0 | | <0.57 | 1.1.0 |

Setup

iOS

You need to include the NSLocationWhenInUseUsageDescription key in Info.plist to enable geolocation when using the app. In order to enable geolocation in the background, you need to include the NSLocationAlwaysUsageDescription key in Info.plist and add location as a background mode in the 'Capabilities' tab in Xcode.

Open project.xcodeproj in Xcode

Drag RNCGeolocation.xcodeproj to your project on Xcode (usually under the Libraries group on Xcode):

Link libRNCGeolocation.a binary with libraries

Click on your main project file (the one that represents the .xcodeproj) select Build Phases and drag the static library from the Products folder inside the Library you are importing to Link Binary With Libraries (or use the + sign and choose library from the list):

Android

1. In android/app/build.gradle

   ...
   dependencies {
       ...
       implementation project(':nunlup-services-geolocation')
   }

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

   buildscript {
       /**
        + Project-wide Gradle configuration properties
        */
       ext {
           compileSdkVersion   = 28
           targetSdkVersion    = 28
           buildToolsVersion   = "28.0.3"
           supportLibVersion   = "28.0.0"
           googlePlayServicesVersion = "16.0.0"
       }
       repositories { ... }
       dependencies { ... }
   }

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

2. In android/setting.gradle

   ...
   include ':nunlup-services-geolocation'
   project(':nunlup-services-geolocation').projectDir = new File(rootProject.projectDir, '../node_modules/nunlup-services-geolocation/android')

3. 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 'nunlup-services-geolocation';
...

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

setRNConfiguration(options) (iOS only)

• options:

  | Name | Type | Default | Description | | -- | -- | -- | -- | | skipPermissionRequests | bool | false | If true, you must request permissions before using Geolocation APIs. | | authorizationLevel | string | -- | Changes whether the user will be asked to give "always" or "when in use" location services permission. Any other value or auto will use the default behaviour, where the permission level is based on the contents of your Info.plist. Possible values are whenInUse, always and auto. |

requestAuthorization() (iOS only)

Request suitable Location permission based on the key configured on pList. If NSLocationAlwaysUsageDescription is set, it will request Always authorization, although if NSLocationWhenInUseUsageDescription is set, it will request InUse authorization.

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 | forceRequestLocation | bool | false | Force request location even after denying improve accuracy dialog

watchPosition(successCallback, ?errorCallback, ?options)

• successCallback: Invoked with latest location info.

clearWatch(watchId)

• watchId (id returned by watchPosition)

stopObserving()

Stops observing for device location changes. In addition, it removes all listeners previously registered.

FAQ

1. 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
