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 diagnostics


SDKs associated with Xamarin target platforms and development IDEs are equipped with comprehensive analytic tools. Utilizing these tools, developers can identify issues causing app freezes, crashes, slow response time, and other resource-related problems (for example, excessive battery usage).

Xamarin.iOS applications are analyzed using the XCode Instruments toolset. In this toolset, there are a number of profiling templates, each used to analyze a certain perspective of application execution (such as the allocations template that was used in Chapter 2, Memory Management, for memory profiling). Instrument templates can be executed on an application running on the iOS simulator or on an actual device.

Similarly, Android applications can be analyzed using the device monitor provided by the Android SDK. Using Android Monitor, memory profile, CPU/GPU utilization, and network usage can also be analyzed, and application-provided diagnostic...
