Meteor's cordova: geolocation plugin doesn't work on mobile

问题

I'm deploying my Meteor (1.2.0.2) app to an Android device.

I installed the plugin by

 meteor add cordova:cordova-plugin-geolocation@1.0.0

Added Cordova plugin cordova-plugin-geolocation@1.0.0.

I used the plugin by:

    document.addEventListener("deviceready", onDeviceReady, false);
    function onDeviceReady() {
        navigator.geolocation.getCurrentPosition(function(p){ // onSuccess
            console.log(p);
        }, function(e){
            console.log(e);
        });
    }

On desktop works perfectly (print p as Geolocation object) but on mobile it just ignores the callbacks (both success and errors).

I tested it in Chrome DevTools (chrome://inspect) by setting breakpoints. It steps until .getCurrentPosition call but then (either step over or step in) just skips both callbacks (and If I set a breakpoint within them, they are just not hit).

I even tried

navigator.geolocation.getCurrentPosition(function(p){ console.log(p); 

both on Desktop console (works)

undefined
Geolocation { ... }

and mobile (does not work)

undefined
// nothing else is printed

Maybe has it something to do with app's permissions?

EDIT: I verified AndroidManifest.xml and the permissions are actually set by the plugin:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

@dragonmnl,

GPS is unreliable.

You did not talk about timeout, I must assume you have NOT set the timeout long enough. Try setting it to about 20 seconds -- as a minimum.

If your readings are poor, or you are timing out

• go outside
• make sure you have a clear view of all horizons (nothing blocking the view)
• walk in a big circle, about 15ft in diameter

In about 30-45 seconds you should have a reading. This will make sense when you read the link I gave you.
