Android Framework is one of the core components of the Android operating system, which provides many important functions and services for applications, such as interface design, multimedia support, network connection and so on. As an Android application developer, it is very important to understand the basic principles and mechanisms of the Android Framework.
With more and more Android developers, companies are increasingly looking at a programmer's understanding and thinking about the underlying principles of Android when screening Android programmers. People who often interview know that Framework is now a must-ask knowledge point for interviews
How to learn Android Framework ? It has become an imminent problem for many people. Regarding how to learn Android Framework development knowledge , developers who are still confused can refer to this advanced document "Android Framework Source Code Development Manual" compiled by Tencent bosses.
The content covers : system startup process analysis, cross-process communication IPC, Handler, AMS, WMS, Surface, SurfaceFlinger, PKMS, etc. There are 10 chapters in total. At the end of the chapter, there are related interview questions to help you learn the Framework better and pass the interview difficulties. .
This study manual aims to introduce the core concepts and technologies of Android Framework through examples and cases, so as to help developers better understand the design and development of Android applications.
This manual is suitable for programmers with certain experience in Android application development, hoping to help developers better understand and master this technology through in-depth study of Android Framework.
