IONIC 2 - GeoLocation ask or permission every time when app open

Question

I am using ionic Geolocation Library for getting user current location. When i open the application every time it's asking for the permission. I have use the following code to get the current location from user.

let options = {timeout: 20000, enableHighAccuracy: true , maximumAge: 0};
this.geolocation.getCurrentPosition(options).then((resp) => {

})

Can you please help me why it asking for the permission every time.

Thanks

This can happen because the Ionic platform may not be fully ready before code requesting a user location gets called. See this Ionic forum discussion.

The Ionic-Native geolocation plugin, which uses native device location permissions & is only set once, AND the browser window in which the Ionic Cordova app run are BOTH asking for user permission.

In my case, and I presume yours, the alert that shows up on every launch references the browser 'container' and 'index.html', indicating it's the browser asking for permission. The app-specific alert only shows up once on the initial launch after installation.

I had the same problem w/a geolocation service call in a modal that appears right after launch. My solution was to:

1. Inject the Platform from ionic-angular into the component making the geolocation request, and then

2. Wrap my geolocation call in platform.ready().then(), to ensure it only ran after the platform was, y'know, "ready."

This removed the duplicate alerts, and it only asks once immediately after first launch.

 import { Component, OnInit } from '@angular/core';
 import { Platform } from 'ionic-angular';
 import { Geolocation } from '@ionic-native/geolocation';

 constructor(private platform: Platform, private geo: Geolocation) {}

 ngOnInit() {

    this.setLocation(); 
 }

  setLocation() {
     this.platform.ready().then(() => { 
        return this.geo.getCurrentPosition()
                       .then(pos => {//do stuff w/position});
     });
  }
