In order to manage application resources, one must have a deeper understanding of the application lifecycle. Application lifecycle events, outlined in this chapter, are the main access points to underlying platform runtime on both iOS and Android. If used properly, the event delegates and event methods on both platforms can help developers save valuable resources and avoid memory problems.

Other concepts discussed were garbage collection, object references, and automatic reference counting. These concepts make up the foundation of memory management on target Xamarin platforms.

We also had a closer look at the diagnostic and profiling tools for target platforms and how they can be used effectively. While iOS and Android platforms each have a native app to analyze memory allocations, Xamarin Profiler provides a unified solution for both platforms.

Finally, useful patterns were outlined for different memory related issues and pitfalls. To analyze these patterns, Xamarin Profiler and Instruments...
