In June 2017, the Alibaba Hand Tao technical team launched the first non-intrusive mobile hot update solution in history - Sophix. In the three major areas of Android hot repair: code repair, resource repair, SO repair, as well as the security and ease of use of the solution, Sophix has achieved industry-leading.
"In-depth exploration of the principles of Android hot repair technology" starts from the authoritative interpretation of the development process of Alibaba Sophix solution, and shares the original discovery of the bottom layer of the system by the Alibaba Hand Taoist technical team. It is the first book in the industry to fully introduce the principle of hot repair.

Since 2014, Taobao has defined and led the trend of Android componentization and hot repair technology in the industry. As for the latecomer Instant App, it has also been more or less affected by the domestic technology trend. Today, I am very happy to see the teammates carefully and systematically organize this technology into a book. In this book, you can not only see the in-depth summary of the development history of the hot repair technology trend, see the unremitting efforts of domestic programmers in the continuous breakthrough of Android system-level technology, but also see domestic programmers insist on creating world-class excellence Ambition for professional mobile technology products!

Application hotfixing is a somewhat arcane and controversial technology, but it does give application developers the ability to "fix an engine on a plane." This book systematically expounds the application hot-fix technology on the Android platform from the perspective of the principle and code implementation of the Android application hot-fix technology and comparison of various schemes. Techies who are curious about Android app hotfixing, this special book is not to be missed. ——Pan Aimin, a famous writer in the field of computer technology and chief architect of Alibaba Fliggy Business Unit
Alibaba Wireless launched the Android hot repair technology Dexposed for the first time in the industry three years ago. This is an era in which technology changes the pattern, and it is also an era in which talented people are born in large numbers! ——Feng Forest (Wu Feng), former architect of mobile phone Taobao and founder of Green Alliance
The Birth Background of "Exploring the Principles of Android Hot Repair Technology"
Hot repair technology can be seen as an inevitable product of the development of the Android platform to a certain stage. It is a technical application that maintains traffic and causes minimal disturbance to users. The logic of its emergence all contains the fact that wireless applications have developed to a new stage, that is, how to better maintain expensive traffic.
Although there are many solutions, there are basically no books that explain the details of hot repair technology in depth and systematically. Most of the various Android books on the market at home and abroad only cover the basic knowledge of Android development in general, but basically there are no chapters that include hot repair technology. At most it was just a pass. Even if there are many open source hotfix solutions, it still takes a lot of time and energy to hard-code the code yourself.
Instead of looking at an obscure project, it is better to find a professional and detailed book, which will help you understand the difficulties and key points involved in this technology more systematically and comprehensively.
The Alibaba Hand Tao technical team has organized and summarized the technical details in the development process of the mobile hot repair solution Sophix, and shared them with the majority of Android developers in the form of free e-books. This is the original intention of "Exploring the Principles of Android Hot Repair Technology in Depth".
For every developer who wants to dig deep into the field of Android development, this is an advanced book that should not be missed.
What are the main highlights of this book?
This book consists of five chapters and 160 pages. It is recommended to read them in chapter order. Of course, if you are interested in some aspects, you can also skip reading.
