android - 如何从 Android 手机使用 Cordova Geolocation 插件获取地理位置？

Question

我正在使用 Ionic 框架构建一个 Android 应用程序，我想从我的手机中使用 Cordova Geolocation ( https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-geolocation/ ) 获取地理位置。

在浏览器（离子服务）中测试实现时，一切似乎都运行良好。但是当我尝试在手机（Samsung Galaxy S6）上测试它时，不会显示位置。

不幸的是，我看不到使用 ionic cordova run android 进行调试的任何错误。

有谁知道如何解决这个问题？

跟踪页面.ts

import { Component, OnInit } from '@angular/core';
import { Geolocation } from '@ionic-native/geolocation/ngx';
import * as moment from 'moment';
import { NativeGeocoder, NativeGeocoderOptions, NativeGeocoderResult } from '@ionic-native/native-geocoder/ngx';

@Component({
  selector: 'app-tracking',
  templateUrl: './tracking.page.html',
  styleUrls: ['./tracking.page.scss'],
})
export class TrackingPage implements OnInit {
  geoLatitude: number;
  geoLongitude: number;
  geoAccuracy: number;

  watchLocationUpdates: any;
  loading: any;
  isWatching: boolean;

  // Geocoder configuration
  geoencoderOptions: NativeGeocoderOptions = {
    useLocale: true,
    maxResults: 5
  };

  constructor(
    private geolocation: Geolocation,
    private nativeGeocoder: NativeGeocoder
  ) { }

  getMoment() {
    return moment().milliseconds(0);
  }

  ngOnInit() {
    document.addEventListener('deviceready', onDeviceReady, false);
    function onDeviceReady() {
        console.log('navigator.geolocation works well');
    }
  }

      // Start location update watch
      watchLocation() {
        let options = {
          maximumAge: 3600000,
          timeout: 3000,
          enableHighAccuracy: true,
       }
        this.isWatching = true;
        this.watchLocationUpdates = this.geolocation.watchPosition();
        this.watchLocationUpdates.subscribe((resp) => {
          this.geoLatitude = resp.coords.latitude;
          this.geoLongitude = resp.coords.longitude;
          this.geoAccuracy = resp.coords.accuracy;
          timestamp: this.getMoment().format('x');
          // this.getGeoencoder(this.geoLatitude, this.geoLongitude);
        });
      }

      // Stop location update watch
      stopLocationWatch() {
        this.isWatching = false;
        console.log('this.isWatching = ', this.isWatching);
        this.watchLocationUpdates.unsubscribe();
      }
}
