Mastering Cross-Platform Development with Xamarin

Overview of this book

The main goal of this book is to equip you with the required know-how to successfully analyze, develop, and manage Xamarin cross-platform projects using the most efficient, robust, and scalable implementation patterns. This book starts with general topics such as memory management, asynchronous programming, local storage, and networking, and later moves onto platform-specific features. During this transition, you will learn about key tools to leverage the patterns described, as well as advanced implementation strategies and features. The book also presents User Interface design and implementation concepts on Android and iOS platforms from a Xamarin and cross-platform perspective, with the goal to create a consistent but native UI experience. Finally, we show you the toolset for application lifecycle management to help you prepare the development pipeline to manage and see cross-platform projects through to public or private release.

Troubleshooting and diagnosis

Profiling is the term used to describe the dynamic system analysis while the target application is running. Profilers generally collect data about metrics such as CPU utilization, framerate values, and most importantly data about memory allocations. Especially with Xamarin projects, since we are dealing with multiple platforms, profiling becomes an important part of testing and diagnostics.

There are numerous tools that one can use to profile memory usage on Xamarin projects, Xamarin Profiler being the only one that can be used both for Xamarin.iOS and Xamarin.Android applications.

Xamarin Profiler

Xamarin Profiler is the newest addition to the Xamarin Suite. This profiler has the advantage over other platform-specific applications since it can be run either on OS X or Windows targeting Xamarin.Android or Xamarin.iOS applications.
