Overview of this book

Need to ensure you can always create the best Windows apps regardless of platform? What you need are solutions to the biggest issues you can face, so you can always ensure you’re making the right choices and creating the best apps you can. The book starts with recipes that will help you set up the integrated development environment before you go ahead and design the user interface. You will learn how to use the MVVM design pattern together with data binding, as well as how to work with data in different file formats. Moving on, you will explore techniques to add animations and graphics to your application, and enable your solution to work with multimedia content. You will also see how to use sensors, such as an accelerometer and a compass, as well as obtain the current GPS location. You will make your application ready to work with Internet-based scenarios, such as composing e-mails or downloading files, before finally testing the project and submitting it to the Windows Store. By the end of the book, you will have a market-ready application compatible across different Windows devices, including smartphones, tablets, and desktops.

Reading data from a compass

The accelerometer is not the only sensor that can be used by UWP applications. The second one that is presented in this chapter is a compass. It allows you to get a heading relative to the magnetic north or geographic true north, if available. Of course, such a heading is returned in degrees. You will learn how to obtain values from a compass sensor in this recipe.

As an example, you will create an application that presents a compass rose that rotates according to the current heading relative to the magnetic north.

Getting ready

To step through this recipe, you only need the automatically generated project.

How to do it...

To prepare an example of rotating a compass rose according to data obtained from the compass sensor, perform the following steps:

  1. Add the CompassBackground.png and CompassIndicator.png files to the Assets directory. These .png files are available together with the code attached to this chapter.

  2. Add two Image controls, representing compass background...
