Computer books
Deep understanding of Android: Volume II is the second book in the "deep understanding of Android" series. After its first book was published, it was highly praised by many readers and passed on to the android developer community. This book not only inherits the advantages of the first book, but also corrects some shortcomings in its micropoints. It also makes innovations in the overall thinking of writing, it emphasizes the analysis of the internal implementation principles and working mechanisms of each module in the Android system from the perspective of system designers. In terms of specific content, this book focuses on the Java layer of the android framework and provides in-depth and meticulous analysis of the core modules and services involved in the Java layer. Through this book, readers can not only have a deeper understanding of the Android system, but also master the ability to analyze large complex source code.
The book consists of eight chapters: Chapter 1st describes the preparations required to read this book, including downloading and compiling the android 4.0 source code, setting up the eclipse environment, and running the Android system process (system_process) in Chapter 2nd, the implementation of Java binder and messagequeue is deeply analyzed. Chapter 3rd details the working principle of systemserver, these services include entropyservice, dropboxmanagerservice, diskstatsservice, devicestoragemonitorservice, samplingprofilerservice, and clipboardservice; chapter 2 analyzes in detail the packagemanagerservice, which is responsible for querying package information and installing, uninstalling, and updating apk in the system. Chapter 2 analyzes the core service powermanagerservic, which is responsible for Power Management in the Android system. The principles of E are deeply analyzed. Chapter 6th focuses on activitymanagerservice, in-depth research on its startup, activity creation and startup, broadcastreceiver working principle, and process management in Android; chapter 2 conducts in-depth analysis on the creation and startup of contentprovider, the implementation of SQLite, cursor query, and close; Chapter 7th takes contentservice and accountmanagerservice as the analysis object, this section describes the implementation of the data update notification mechanism, account management, data synchronization, and other related knowledge.
