Sillars D. High Performance Android Apps. Improve Ratings with Speed, Optimizations, and Testing

O’Reilly, 2015. — 248 p.You are building an Android application (or you already have.) Despite this, are you not totally happy with your apps performance? (why else did you pick up this book?) Uncovering mobile performance issues is a job that is never complete. In my research, I found that 98% of apps tested had potential performance improvements. The goal of this book is to help understand the pitfalls of mobile performance, expose some of the tools to test for issues so that you can catch any major performance issues in your mobile
application before it impacts your customers.
Studies have shown that customers expect mobile applications to load quickly, to rapidly respond to user interactions, and be smooth and pleasing to the eye. As application get faster, user engagement and revenues increase. Mobile applications built without an eye on performance are uninstalled at the same rate as those that crash. Apps that inefficiently use resources cause unnecessary battery drain. The #1 complaint to carriers and device manufacturers is battery life.
I have spoken to thousands of developers about Android app performance over the last few years, and few developers were aware of the tools available for solving the issues they were having.
The consensus is clear: mobile applications that are fast and run smoothly are used more often and make more money for the developers. With that information, it is surprising that more developers are not using the tools that are available to diagnose and pinpoint performance issues in their apps. By focusing on how performance improvements affect the user experience, you can quickly identify the Return on Investment that your performance work has made on your mobile application.
This book covers a wide range of topics centering around Android Performance. Anyone associated with mobile development will appreciate the research around application performance. Developers of mobile applications will find the arguments and issues around app performance useful, but the tools used to isolate the issues are Android specific. Testers will find the tutorials of tools used to test Android performance useful as well.Introduction To Android Performance.
