Geolocation

Geolocation APIは、GPSを使用してデバイスの現在位置を取得および追跡するための簡単な方法を、 可能であれば高度、方位、および速度情報とともに提供します。

iOS Notes

Apple requires privacy descriptions to be specified in Info.plist for location information:

Name: Privacy - Location Always Usage Description Key: NSLocationAlwaysUsageDescription

Name: Privacy - Location When In Use Usage Description Key: NSLocationWhenInUseUsageDescription

Read about Setting iOS Permissions in the iOS Guide for more information on setting iOS permissions in Xcode

Android Notes

This API requires the following permissions be added to your AndroidManifest.xml:

<!-- Geolocation API -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-feature android:name="android.hardware.location.gps" />

The first two permissions ask for location data, both fine and coarse, and the last line is optional but necessary if your app requires GPS to function. You may leave it out, though keep in mind that this may mean your app is installed on devices lacking GPS hardware.

Example

import { Plugins } from '@capacitor/core';

const { Geolocation } = Plugins;

class GeolocationExample {
  async getCurrentPosition() {
    const coordinates = await Geolocation.getCurrentPosition();
    console.log('Current', coordinates);
  }

  watchPosition() {
    const wait = Geolocation.watchPosition({}, (position, err) => {
    })
  }
}

API

getCurrentPosition(…)

getCurrentPosition(options?: GeolocationOptions) => Promise<GeolocationPosition>

Get the current GPS location of the device

Param Type
options GeolocationOptions

Returns: Promise<GeolocationPosition>


watchPosition(…)

watchPosition(options: GeolocationOptions, callback: GeolocationWatchCallback) => CallbackID

Set up a watch for location changes. Note that watching for location changes can consume a large amount of energy. Be smart about listening only when you need to.

Param Type
options GeolocationOptions
callback (position: GeolocationPosition, err?: any) => void

Returns: string


clearWatch(…)

clearWatch(options: { id: string; }) => Promise<void>

Clear a given watch

Param Type
options { id: string; }
