Tracking latitude and longitude
In this recipe, we will implement the most fundamental use of location services, tracking latitude and longitude. Our sample application will be a navigation helper which displays all the available location information. We will also review the different ways in which the phone gets its location information and their attributes.
Getting ready
We will be working in Visual Studio for this tutorial, so start by opening Studio and creating a new Windows Phone 7 application using the Windows Phone Application project template.
All the location/GPS-related methods and classes are found in the System.Device assembly, so add this reference next:
We will need some UI to start tracking and displaying the data, so go to the MainPage.xaml
file, if it's not already open. Change the ContentPanel
from a Grid
to a StackPanel
, then add a button to the designer, and set its Content
property to Start Tracking
. Next add four TextBlocks
. Two of these will be Latitude and Longitude...
