Today's world is all about perfection, and there are hundreds of applications that are released each day out of which only a few succeed. Making sure that the app looks, performs, and behaves as expected is one of the biggest challenge developers face today. The main goal of this book is to teach developers to implement DevOps to build, test, and deliver. This book will teach you to implement Mobile DevOps at every stage of your application's lifecycle with Visual Studio and Xamarin Mobile Lifecycle solutions. Later, it will also show you how to leverage Mobile Center's continuous integration and automated testing to develop a high-quality applications. Next, you’ll see how to mobilize your on-premises data to the cloud and increase your productivity with code reuse. Finally, you’ll discover how to find and fix bugs beforehand, improving the efficiency of your application while it is being developed. By the end of this book, you will be well-versed with Mobile DevOps techniques, delivering high quality and high performance mobile apps.

Using Android monitoring tools

An Android app's performance is equally important for a great user experience and a fast-responsive application. Android Device Monitor (ADM) is a great tool to identify performance issues and build reports upon them, for profiling and to ensure good application performance when it comes to Android apps:

Go to Visual Studio, and from the toolbar, run Android Device Monitor:

A new application, Android Device Manager, should open:

Go back to Visual Studio and run PhoneCallApp to get the device listed in Android Device Monitor.
You can run the application on an emulator or a physical device connected to the computer.

Once the application has started, come back to Android Device Monitor and you should be able to see the device running in the left pane.
Under the device name, you should be able to see all the processes running on the device...
