What this book covers
Chapter 1, Introduction: Why High Performance?, provides an introduction to the topic, the current state of the art in Android, and the importance of performance in an Android application.
Chapter 2, Efficient Debugging, covers the tools provided by the Android SDK (and some externals) that are regularly used to debug and profile Android applications.
Chapter 3, Building Layouts, will take you through the techniques used to optimize Android routines, write applications that use memory efficiently, and explain concepts from memory allocation to garbage collection.
Chapter 4, Memory, provides many insights to the UI design that need to be learnt in order to create an efficient UI that loads fast, without giving a lag perception to the user and that gets updated efficiently.
Chapter 5, Multithreading, explains all the different threading options in an Android application and when we should apply each. Some advanced techniques, such as IPC, will be also shown with practical code.
Chapter 6, Networking, shows techniques used to perform efficient network operations, and techniques to retrieve data from servers such as exponential back offs or avoiding polling.
Chapter 7, Security, covers techniques to secure an Android application, how to make use of the security encryption mechanisms provided by Android natively, and how to get information about connections or just be notified of connection changes.
Chapter 8, Optimizing Battery Consumption, provides typical examples of code that exhausts battery life, how to prevent it, and how to measure battery consumption from an application in every kind of situation; many developers don't know how to behave while developing apps to take a photo or a video, handling with previews, and saving data.
Chapter 9, Native Coding in Android, this chapter is a workaround in the world of native code and C++ in Android and its usage.
Chapter 10, Performance Tips, helps developer to be guided in common coding situations, where wrong choices can compromise app efficiency; this will be a best practice guide related to topics not dealt with in previous chapters.
