Getting to Know More About Your Windows Phone

Introduction

There are cases when Windows Phone developers need to retrieve device information so that they can author their applications to draw the maximum possible juice from the device.  They can also use this data to see what hardware their customers use and optimize their application to provide a better experience for the most popular harware.

Device Information

Windows Phone platform has a rich set of APIs to support getting device information. These APIs reside in the DeviceStatus class in the Microsoft.Phone.Info namespace.

The DeviceStatus class has APIs to get information like the hardware version of the phone, total memory on the phone, etc.

Hands-on

Let us write an application that gets the device information and displays it to the user.

Create a new Windows Phone application called WPDeviceInfoDemo.

When prompted for the target OS version, select WP7.1 and click OK.

Select the Windows Phone Platform
Select the Windows Phone Platform

Next, add controls on the MainPage to display “Current memory”, “Total memory”, “Device Hardware version”, “Device Firmware Version”, and a checkbox to show if a “Physical Keyboard” is present. Add a button titled “Get Device Data,” which we will use to get the device information.

Next, open MainPage.xaml.cs and include the Microsoft.Phone.Info namespace.

using Microsoft.Phone.Info;

Next, add an event handler for the click event on the button. In this method, we will get the device information using the methods of the DeviceStatus class.

private void buttonGetDeviceData_Click(object sender, RoutedEventArgs e)
        {
            textBlockCurrentMemoryValue.Text = DeviceStatus.ApplicationCurrentMemoryUsage.ToString();
            textBlockTotalMemoryValue.Text = DeviceStatus.DeviceTotalMemory.ToString();
            textBoxDeviceFWVersion.Text = DeviceStatus.DeviceFirmwareVersion;
            textBoxDeviceHardwareVersion.Text = DeviceStatus.DeviceHardwareVersion;
            checkBoxPhysicalKeyboardPresent.IsChecked = DeviceStatus.IsKeyboardPresent;
        }

We are now ready to build and test our application. If you are having issues compiling the code, you can download copy of the source code below.

When you run the application, you will find that when you click the button, the device information is retrieved and shown on the screen.

Caveat: If you run the application in an emulator, the device hardware and device firmware will be reported as 0.0.0.0.

Other uses

You can also use the DeviceStatus calss to see the power source for the device, and also whenever a physical keyboard is deployed.

Summary

In this article, we learned how we can get device information.
