Trouble showing Google Maps in Intel XDK JavaScript project

Other Questions JavaScript
1

I’m working on an Intel XDK project and I’m stuck trying to display Google Maps. I’ve been at it for hours but the map just won’t show up on the screen.

Here’s what I’ve done so far:

  • Added the Google Maps API script to my index.html
  • Created a div for the map in the HTML
  • Set up a JavaScript file to initialize the map
  • Used navigator.geolocation to get the user’s location

My map div looks like this:

<div id="mapContainer" style="height: 400px; width: 100%;"></div>

And my map init function is something like:

function startMap() {
  const mapOptions = {
    zoom: 14,
    center: new google.maps.LatLng(userLat, userLng)
  };
  const map = new google.maps.Map(document.getElementById('mapContainer'), mapOptions);
}

I call this function when the page loads, but nothing appears. Any ideas what I might be doing wrong? I’m totally lost at this point. Thanks for any help!

I encountered a similar issue in my XDK project. One often-overlooked aspect is the timing of the map initialization. Ensure you’re calling your startMap function after the DOM has fully loaded. You can achieve this by wrapping your code in a deviceready event listener:

document.addEventListener('deviceready', function() {
    startMap();
}, false);

Additionally, verify that your Google Maps API script is loading correctly. Sometimes, network issues or content blockers can interfere. Try adding an error callback to your script tag:

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY" onerror="console.error('Google Maps failed to load')"></script>

This will help you identify if the API is loading properly. If these steps don’t resolve the issue, consider checking your XDK’s build settings and ensure that geolocation permissions are properly set.

I’ve been there, mate. XDK can be a real pain sometimes. One thing that worked for me was making sure the viewport meta tag was set correctly in the index.html. Try adding this if you haven’t already:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">

Also, double-check that you’re not accidentally hiding the map div with CSS. I once spent hours debugging only to realize my map was hidden behind another element.

If you’re still stuck, try simplifying. Remove the geolocation bit temporarily and hardcode some coordinates. Sometimes it’s easier to get the basics working first, then add complexity.

Lastly, don’t forget to check the browser console for any error messages. They can be cryptic, but often point you in the right direction.

Keep at it, you’ll crack it eventually!

hey tom, had similar issues. make sure ur API key is valid n not restricted. also, try adding a console.log in ur startMap function to check if its being called. XDK can be finicky with scripts loading. if all else fails, try a different map library like leaflet. luck!
