Google analytics for Windows Phone applications

Using an analytics solution to collect some information on your application usage is a real added value to make it a great application. Of course there are informations available on the market place but these informations are quite limited. You only have access to the number of daily download and the installation base but you don’t have information on which part of your app is most used or the time spent on each page of your application. So here I’m giving the steps required to monitor your application usage with online an analytics services like Google Analytics.


Microsoft was kind enough to create a library to make this task easy. So the first step is to download and install this library. You can get the latest version of the Microsoft Silverlight Analytics Framework here :
You also need an analytics service provider. Here I am using Google analytics, it’s free and quite powerfull for a free product. If you want to use Google Analytics, you will need to create an account and add a website :


Add references to the following assemblies by manually browsing to C:\Program Files\Microsoft SDKs\Microsoft Silverlight Analytics Framework.4\WP7:

  • Microsoft.SilverlightMediaFramework.Helpers.Phone (Microsoft.SilverlightMediaFramework.Compatibility.Phone.dll)
  • Microsoft.WebAnalytics (Microsoft.WebAnalytics.dll)
  • Microsoft.WebAnalytics.Behaviors (Microsoft.WebAnalytics.Behaviors.dll)
  • Google.WebAnalytics (Google.WebAnalytics.dll)

Add reference to the following assemblies using the .Net tab in the “Add reference” dialog box:

  • System.Device
  • System.Windows.Interactivity

The documentation tells you to but DO NOT ADD a reference to ComponentModel (System.ComponentModel.Composition.dll) !!! Otherwise you will get an error about the type AssemblyCatalog beeing defined in two different assemblies.

Create service class derived from IApplicationService

using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.ComponentModel.Composition.Hosting;

namespace AnalyticsSample
    public class AnalyticsAppService : IApplicationService
        /// <summary>
        /// Initialize the assembly catalogs for the Silverlight Analytics Framework
        /// </summary>
        /// <param name="context">the application service context</param>
        public void StartService(ApplicationServiceContext context)

            CompositionHost.Initialize(new AssemblyCatalog(
                new AssemblyCatalog(typeof(Microsoft.WebAnalytics.AnalyticsEvent).Assembly),
                new AssemblyCatalog(typeof(Microsoft.WebAnalytics.Behaviors.TrackAction).Assembly),
                new AssemblyCatalog(typeof(Google.WebAnalytics.GoogleAnalytics).Assembly));

        /// <summary>
        /// Stop the service
        /// </summary>
        public void StopService()

Then you will need to modify your App.xaml file:


    <!--Ressources d'applications-->

        <!-- Must be first service -->
           Launching="Application_Launching" Closing="Application_Closing"
           Activated="Application_Activated" Deactivated="Application_Deactivated"/>
        <!-- Then the Analytics service we created -->
        <!-- And the Web analytics service provider -->
                <ga:GoogleAnalytics WebPropertyId="UA-12345-1"/>


Here are the modification:

  • Add the namespace for “local” (AnalyticsSample: our application namespace), “mwa” (Microsoft.WebAnalytics) and “ga” (Google.WebAnalytics).
  • Add the AnalyticsAppService you defined earlier to the Application.ApplicationLifetimeObjects node. The line must be typed after shell:PhoneApplicationService, the order is important !
  • Add a web analytics service after local:AnalyticsAppService (again the order is important), replace the “UA-12345-1” with the site id from your Google analytics account.
  • Done ! It takes some time to see the result in Google Analytics.

    Tracking Pivot & Panorama control usage

    The previous steps will correctly report information about your application usage per page, however if your application main interface is based on a Pivot or Panorama control you will not have detailled information about it’s usage. Fortunately, the Microsoft Analytics framework allows you to track your Pivot control usage. Here is how:
    Add a reference to the Microsoft.WebAnaltyics.Controls.WP7 by manually browsing to “C:\Program Files\Microsoft SDKs\Microsoft Silverlight Analytics Framework” with the “Add reference” dialog box.

    Edit your application page and make the following modification:
    * Add the namespace for “i” (System.Windows.Interactivity) and “mwab” (Microsoft.WebAnalytics.Behaviors)
    * Bind the SelectionChanged event to the TrackAction behavior from the analytics framework.

            <i:EventTrigger EventName="SelectionChanged">

    You can also make these modifications using Microsoft Expression Blend.

    Edit your AnalyticsAppService and add an AssemblyCatalog line to the StartService method previously defined:

    CompositionHost.Initialize(new AssemblyCatalog(
        new AssemblyCatalog(typeof(Microsoft.WebAnalytics.AnalyticsEvent).Assembly),
        new AssemblyCatalog(typeof(Microsoft.WebAnalytics.Behaviors.TrackAction).Assembly),
        new AssemblyCatalog(typeof(Microsoft.WebAnalytics.Controls.HandlePanorama).Assembly),
        new AssemblyCatalog(typeof(Google.WebAnalytics.GoogleAnalytics).Assembly));

    The PanoramaItem/PivotItem Name or Header (if there is no Name) is then tracked in the event’s ActionValue.

Using Silverlight charting control in Windows Phone

I’m currently working on a small app for Windows Phone. I wanted to add some simples charts to the application and found silverlight contained a charting control. As a reminder for me and as an helpfull example for you, here are the necessary steps to display a simple chart in your Windows Phone Application. The example below was tested against the Windows Phone SDK version 7.1.


First, you need to install the silverlight libraries from

  • Silverlight Phone toolkit
  • Silverlight 3 (not 4 ! not 5 !): It’s an old version but unfortunately, newer silverlight versions are not supported. In fact, Windows Phone SDK is build around Silverlight 3 with some addition from silverlight 4.

Next, you need to add manually the references to the silverlight toolkit by browsing to the Silverlight install folder:

  • System.Windows.Controls.DataVisualization.Toolkit.dll (should be in C:\Program Files\Microsoft SDKs\Silverlight\v3.0\Toolkit\Nov09\Bin)
  • System.Windows.Controls.dll (should be in C:\Program Files\Microsoft SDKs\Silverlight\v3.0\Libraries\Client\)


We need to add the namespace for the charting toolkit, here named “chartingToolkit”:

   mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768"
   FontFamily="{StaticResource PhoneFontFamilyNormal}"
   FontSize="{StaticResource PhoneFontSizeNormal}"
   Foreground="{StaticResource PhoneForegroundBrush}"
   SupportedOrientations="Portrait" Orientation="Portrait"

Then we add the control to our application page :

            <chartingToolkit:Chart x:Name="ChartControl" Title="My chart">
                    <chartingToolkit:LinearAxis Orientation="Y" ShowGridLines="True" />
                <chartingToolkit:ColumnSeries IndependentValueBinding="{Binding Name}" DependentValueBinding="{Binding Value}" />

Note the binding parameters, they are linked to the data object we defined to hold chart data :

    public class ChartData
        public string Name { get; set; }
        public double Value { get; set; }

We also need some data so we generate some :

            List<ChartData> data = new List<ChartData>();
            for (int i = 0; i < 10; i++)
                data.Add(new ChartData(){
                    Name = String.Format("data {0}", i + 1),
                    Value = i

The final step is to set the data source of the data serie:

            ColumnSeries series = ChartControl.Series[0] as ColumnSeries;
            if (series != null)
                series.ItemsSource = data;


If you link your project with the wrong silverlight version you might get the following errors :

  • “A first chance exception of type ‘System.InvalidOperationException‘ occurred in Microsoft.Phone.dl”: You probably forgot to add the reference to
  • “A reference to a higher version or incompatible assembly cannot be added to the project”: You probably linked against Silverlight version 5 dll
