import React, { Component } from 'react';
import {Platform,StyleSheet,Text,Button,View} from 'react-native';
import Veery from 'react-native-veery';

export default class App extends Component<{}> {

    componentWillMount(){

                Veery.activate(Veery.GEOPROFILE);
                //Requires react-native-veery 1.4.4 or higher
                //  Veery.activate(Veery.BACKGROUND_GEOLOC | Veery.PREDICTION );
            }

    prediction(){
            Veery.requestPredictionUpdate();// Add this
            Veery.getNextTrip(
                (prediction) =>{

                    if (prediction !== null) {
                        console.log('prediction  App.js==prediction.isOK()===> end',prediction.isOK());
                        if (prediction.isOK()) {
                            console.log('prediction  App.js==prediction.isOutdated()===> end',prediction.isOutdated());
                            console.log('prediction  App.js==prediction.getProbability()===> end',prediction.getProbability());
                        }
                    }

                });
