Author: Yang yunjun Press: Machinery Industry Press ISBN: 9787111417132 mounting Date: April 2013 publication date: 16 open pages: 1 version: 1-1 category: computer> Software and program design> mobile development> more about Android, design and implementation of Android, volume I, computer books, Android design and implementation: volume I is a must-read step for Android Application Development engineers and Android system engineers. It is written by senior Android kernel experts and systematically, thoroughly and thoroughly analyzes the design ideas and implementation principles of the framework of the Android system from the perspective of source code, it provides theoretical guidance for Android Application engineers and System Engineers to solve various problems in their work. In order to reduce the reader's reading cost, the design and implementation of Android: Volume I uses a large number of simple UML class diagrams and sequence diagrams to display the calling process of class hierarchies and methods, this allows readers to quickly read the design and implementation of Android: Volume I and understand its essence! The "android Design and Implementation" series mainly focuses on the four-layer structure of the Android system, and analyzes the design ideas and implementation principles of each layer through the source code, volume I is mainly for the framework layer. There are 12 chapters in the book, which are divided into six parts: BASICS (1st ~ Chapter 2) describes in detail the architecture of Android, the establishment of the source code reading and debugging environment, and the basis of the entire framework ~ Chapter 4) deeply analyzes the mechanism and implementation principles of the android startup process to help readers fully understand the operating basis of system services at the framework layer ~ Chapter 6) focuses on the mechanisms and implementation of the binder in the native framework layer and the Java framework layer, allowing readers to have a deep understanding of the Communication Model Between processes; and the message communication chapter (chapter 7th) it focuses on analyzing the message-driven and asynchronous processing mechanisms of Android, allowing readers to deeply understand the communication model between threads. Package Manager (8th ~ Chapter 9) describes the mechanism and implementation of the Package Manager and the installation method and process of the APK ~ Chapter 12) elaborated on the activitymanagerservice operating mechanism, application and process startup process, and process management mechanism. Android Design and Implementation: Volume I is suitable for middle and senior Android Application Development engineers, Android system development engineers, and Android system architects, and engineers responsible for debugging and optimization of the Android system.
