React native geolocation service for iOS and android.
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/system level. Check the FAQ for more details.
yarn
yarn add react-native-geolocation-service
npm
npm install react-native-geolocation-service
RN Version | Package Version |
---|---|
>=0.60 | >=3.0.0 |
<0.60 | 2.0.0 |
<0.57 | 1.1.0 |
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, for android 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() {
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 }
);
}
}
async requestAuthorization(authorizationLevel) (iOS only)
Request location permission based on the authorizationLevel parameter. Can be either "whenInUse"
or "always"
. You have to configure the plist keys during setup.
When promise resolves, returns the status of the authorization.

useSignificantChanges | bool |
false | Uses the battery-efficient native significant changes APIs to return locations. Locations will only be returned when the device detects a significant distance has been breached (iOS only) |
showsBackgroundLocationIndicator | bool |
false | This setting enables a blue bar or a blue pill in the status bar on iOS. When the app moves to the background, the system uses this property to determine whether to change the status bar appearance to indicate that location services are in use. Users can tap the indicator to return to your app. (iOS only) |

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

React Native 提供了 Geolocation API,让我们可以很方便的获取当前的位置信息,或者监听位置的变化。下面通过样例演示如何使用。 导入 API var Geolocation = require('Geolocation'); 一、获取当前的定位信息 1.getCurrentPosition()方法介绍 static getCurrentPosition(geo_succe

reactNative 获取经纬度踩坑 navigator.geolocation.getCurrentPosition() 百度地图定位不准的问题 最近在做rn的项目要获取经纬度,用到了navigator.geolocation.getCurrentPosition()方法,默认获取的是百度地图坐标系**(经纬度属于WGS84坐标,需要做转换)**,但是后端之前录入的数据是通过高德录入,此时会存

RN 文档上的定位功能需要谷歌框架支持,无疑带来了一些麻烦。github 上也有一些开源库,react-native-geolocation-service等。但是这里还有一个更简便的位置获取 API。 使用内置对象navigator: navigator.geolocation.getCurrentPosition( res => { // conso
geolocation API扩展了geolocation的web规范。在android中,地理位置使用android.location. api。 以下替代库用于在React Native中包含新的位置服务API。 React-native-geolocation-service React-native-location 要请求位置访问,需要在应用程序的AndroidManifest.xml文
yarn add @react-native-community/geolocation --save 或 npm install @react-native-community/geolocation --save import geolocation from "@react-native-community/geolocation" // 然后使用 navigator.geolocat
