====== Google Maps ======
This is the base information on using intents to call the Google Maps app.

[[https://developers.google.com/maps/documentation/android-api/intents]]

===== Basic Map =====
This intent call the Google Maps app to draw a map with its centre at the location provided by latitude and longitude.

<code JavaScript simpleMap.js>

function OnStart()
{
    var lat="51.5117";
    var lng="-0.1275";
    simpleMap(lat,lng);
}
function simpleMap(latitude,longitude)
{
    var packageName = "com.google.android.apps.maps";
    var className = null;
    var action = "android.intent.action.VIEW";
    var uri =  "geo:"+latitude+","+longitude;
    if(app.IsAppInstalled( packageName ))
      app.SendIntent( packageName, className, action,null,uri );
    else
    {
    app.Alert("maps app not installed");
    app.OpenUrl("market://details?id="+packageName);
    }
}
</code>
===== Turn by Turn Navigation =====
This function could be used instead of simpleMap above to start navigating towards the destination.
<code JavaScript navigate.js>
function navigateTo(latitude,longitude)
{
    var packageName = "com.google.android.apps.maps";
    var className = null;
    var action = "android.intent.action.VIEW";
    var uri =  "google.navigation:q="+latitude+","+longitude;
    if(app.IsAppInstalled( packageName ))
      app.SendIntent( packageName, className, action,null,uri );
    else
      app.Alert("maps app not installed");
}
