IBM Worklight 6.0 - WL.Device.Geo.acquirePosition always return timeout

Question

I'm building an application on worklight 6.0 and I'm trying to implement geolocation.

The method WL.Device.Geo.acquirePosition always returns

{"code":3,"message":"Position retrieval timed out."}

I followed these steps:

1. Created a new worklight project

2. Placed this code in my javascript file:

   function wlCommonInit() {
       WL.Device.Geo.acquirePosition(positive, negative, {
           timeout : 30000,
           enableHighAccuracy: true,
           maximumAge:15000
       }); 
   }
   
   function positive(data) {   
       WL.Logger.debug("bbbbbbbbbbb2" + JSON.stringify(data));
   }
   
   function negativa(data) {
           WL.Logger.debug("aaaaaaaaaaaa" + JSON.stringify(data));
   }
   

3. add an android environment

4. add these two permissions in AndroidManifest.xml:

   uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"
   uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"

5. run the app on a samsung s2 with wifi and gps on

Is there anything that I'm missing?

Answer 1

I would also add to the AndroidManifest.xml the following:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

And make sure this is there as well:

<uses-feature android:name="android.hardware.wifi" />

Did you try with a higher timeout value?

Answer 2

See this post for more information.

Instead of doing:

navigator.geolocation.getCurrentPosition(win, fail, opts);

You can do this:

var geo = cordova.require('cordova/plugin/geolocation');
geo.getCurrentPosition(win, fail,opts);

Turns out you have to call the native module of Cordova to make this work without rebooting. You probably solved this or forgot, but may help other people.

Answer 3

I faced this issue also and it was because I was using the WL API before mobile device Geo was ready.

In my case I copied the code from google maps examples code and it initializes everything with:

google.maps.event.addDomListener(window, 'load', initializeMap)

And then in initializeMap() method is where I tried to use the WL.Device.Geo.acquirePosition method.

You must call the initializeMap method in the wlCommonInit() method, not in a "windows load event listener", this way the call to WL.Device.Geo.acquirePosition() will be done when the device GEO is ready.

Also check in Android check in settings -> Location services that you have enabled Use wireless networks and I have had to enable also Location and Google search...
