This article is to share with you about android how to learn the source code content. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

android source code learning materials

We know that Android is based on the Linux kernel, and when analyzing its source code at the runtime library level, we often encounter knowledge such as pipes, sockets, and virtual file systems (VFS). In addition, Android has added specialized drivers to the Linux kernel, such as Logger drivers for logging systems, Binder drivers for interprocess communication, and anonymous shared-memory Ashmem drivers for secondary memory management. When analyzing these Android-specific drivers, you will also encounter data structures related to process and memory management in the Linux kernel. Therefore, it is necessary to master some basic knowledge of the Linux kernel. Here are four classic Linux kernel books.

LinuxKernelDevelopment.

This book is written by Robert Love, and the latest edition is the 3rd edition. This book provides an overview of the design and implementation of the Linux kernel, conceptually describing the design goals and implementation ideas of the various subsystems of the Linux kernel, and is very suitable for beginners to read. From a software engineering perspective, this book is the equivalent of a Linux kernel design document.

UnderstandingtheLinuxKernel.

The book is by Daniel P. Bovet and Marco Cesati and is currently in its third edition. This book provides more details on the implementation of the Linux kernel, describing in detail the important data structures, algorithms, and programming techniques used in kernel development, which is very suitable for advanced readers to read. From a software engineering perspective, this book is the equivalent of a detailed design document for the Linux kernel.

android writing applications for source code learning

After mastering the basic knowledge of the Linux kernel, it is not appropriate to analyze the source code of the Android system immediately, because this is aimless, we should analyze the source code of the Android system with questions or goals. The best way to dig out a problem or goal is to write your own app for Android. By writing applications, we can know what features the Android platform provides, and then we want to understand how these features are implemented, so that we can analyze the source code of the Android system with questions or goals.

Thank you for reading! About "android how to learn the source code" this article is shared here, I hope the above content can be of some help to everyone, so that we can learn more knowledge, if you think the article is good, you can share it to let more people see it!
