Unable to show OpenStreepMap in Tizen wearable web application

I'm trying to open OpenStreetMap with OpenLayers on a wearable simulator using Tizen.

$(function(){

    layers: [
      new ol.layer.Tile({source: new ol.source.OSM()})
    ],
    view: new ol.View({
      center: [0, 0],
      zoom: 2
    }),
    target: 'map' 
});

Map is showing when testing the code in a normal web application, but when running with Tizen as a wearable map, it is not showing.

I get this error while debugging:

GET https://c.tile.openstreetmap.org/2/1/1.png net::ERR_NAME_RESOLUTION_FAILED c.tile.openstreetmap.org/2/2/2.png:1 GET https://c.tile.openstreetmap.org/2/2/2.png net::ERR_NAME_RESOLUTION_FAILED b.tile.openstreetmap.org/2/1/2.png:1 GET 2 more of the same, cant post due reputation

I think it's an issue in config.xml with access. I've tried lots of things, including adding these links to <access origin>. Nothing works and I'm completely stuck.

Any help or tips would be greatly appreciated!

Solution

  • I figured it out, it seems that Tizen somehow blocks the normal OL CDN, use this 

    <script src="https://cdnjs.cloudflare.com/ajax/libs/ol3/4.1.1/ol.js"</script>

    instead and it should be working fine!

    Thanks all for the help.
