How to add POI ?

I'm new for developer AR With POI

I do follow from HERE POIs

This code in js file:

var World = {
loaded: false,

init: function initFn() {
AR.context.onLocationChanged = World.onLocationChanged;
},
onLocationChanged: function onLocationChangedFn(latitude, longitude, altitude, accuracy) {

AR.context.onLocationChanged = null;

World.createMarkerAtLocation(latitude + 0.01, longitude - 0.0005, altitude - 0.06);
},
createMarkerAtLocation: function createMarkerAtLocationFn(latitude, longitude, altitude) {

var markerLocation = new AR.GeoLocation(latitude, longitude, altitude);
var markerDrawable = new AR.ImageDrawable(World.markerDrawable, 3);
var markerObject = new AR.GeoObject(markerLocation, {
drawables: {
cam: markerDrawable
}
});
},

worldLoaded: function worldLoadedFn() {
document.body.removeChild(document.getElementById('loadingMessage'));
}
};

World.init();

And I Run in my android.But my app is not show POIs.

My Question
1. How do I did for POI show in my apps

Excuse me!.I'm not good English

Please make sure that your device is getting an location. To see if it gets a location you can add the following lines inside the "function onLocationChangedFn"

alert('Location received');

This should pop up a message once a location has been received.
