Geolocation not working in device ionic3

Question

I am working with ionic 3 location-based work. I am not able to get current location of latitude and longitude here. I mentioned my usable code. It's working fine in browser level but not working in a mobile device.

code

$ ionic cordova plugin add cordova-plugin-geolocation --variable GEOLOCATION_USAGE_DESCRIPTION="To locate you"
$ npm install --save @ionic-native/geolocation

import { Geolocation } from '@ionic-native/geolocation';

constructor(private geolocation: Geolocation) {}

this.geolocation.getCurrentPosition().then((resp) => {
  console.log( resp.coords.latitude)
 console.log( resp.coords.longitude)
}).catch((error) => {
  console.log('Error getting location', error);
});

Try this:

import { Geolocation } from '@ionic-native/geolocation';
import { Platform } from 'ionic-angular';

//Set the properties in this class
long: any; //longitude
lati: any; //latitude

constructor(private platform: Platform, private geolocation: Geolocation) {
this.platform.ready().then(()=>{

//set options.. 
var options = {
           timeout: 20000 //sorry I use this much milliseconds
       }
//use the geolocation 
this.geolocation.getCurrentPosition(options).then(data=>{
  this.long = data.coords.longitude;
  this.lati = data.coords.latitude;
 }).catch((err)=>{
     console.log("Error", err);
   });
});
}

Let this be in the constructor. Don't forget to agree to the location privacy permission, also enable location option on your Android device(this is probable though).
