SOLVED. Ionic 2 Google Places Autocomplete onPageLoad or ngOnInit Android Device Issue

Sorry for the horrible title but I wanted to get every keyword in!

I’m having a real problem getting something to work and I’d really appreciate it if anyone could poke me in the right direction. I’m using the Google Places Autocomplete feature on a location search field in my app. In the component I have the following code which sets up the autocomplete listeners on the field.


    let input_from = (<HTMLInputElement>document.getElementById("journey_from"));

    let options = {
      types: [],
      componentRestrictions: {country: "uk"}

    let autocomplete = new google.maps.places.Autocomplete(input_from, options);
    let self = this;

    google.maps.event.addListener(autocomplete, 'place_changed', function() {

      let place = autocomplete.getPlace();
      let geometry = place.geometry;

      if ((geometry) !== undefined) { =;
        self.journeySearch.from.longitude = geometry.location.lng();
        self.journeySearch.from.latitude =;
      } else {
        self.journeySearch.from = {name:"",latitude:0,longitude:0};



This all works absolutely fine when testing in the browser AND on an iOS device i.e when I start typing in the field it pops up the list of location suggestions just like it should.

However, on an Android device I get a white screen on start-up and an error message saying “google is not defined”. I checked out the Ionic Conference app because that uses Google Maps and I noticed that in their map component they have their stuff inside onPageLoad. So I moved my code out of ngOnInit and into onPageLoad and tried that. This time the error didn’t appear BUT the autocomplete won’t work i.e when I type in the field no drop-down with locations appears.

So I obviously need to add the listener in ngOnInit. But on an Android device this fails. Any ideas anyone?

My error log from when I run on the device is shown below: Failed to load resource: net::ERR_CACHE_MISS

As I said, this error goes away when I place my code in onPageLoad (but then the listeners don’t actually work)

(this is all in Ionic 2 beta.7 by the way - i.e the latest and greatest)

Oh I’m such a doughnut. It was simply a case of moving the google APIs inclusion up a bit in my index.html. Obviously on iOS it was loading in time but not on Android. Idiot.
