Following the "Alibaba Java Development Manual", Ali brings a second big gift to developers: the industry's first book on Android hot repair principles - " Deep Exploration of Android Hot Repair Technology Principles " , the book for Alibaba Hand Tao Written by the technical team, it is now available for free download.
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 little 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 thoroughly and systematically explain the details of thermal repair technology. 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 thermal 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 it 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.
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.
