Whether it is Java still Android, As a developer , Just look API Document but do not read the source code , You can only stay in the fur forever , Unable to establish a complete knowledge system , Nor can we effectively improve the actual combat development technology .

Want to be more systematic , Really improve your ability , Reading the source code is a very good way : Not limited to reading the source code of major systems , It also includes various excellent open source libraries . By reading the source code , In addition to learning excellent code style and design ideas , Can you really do it “ Know its nature , And know why ”, So as to guide them to use more flexibly API, Find the system more quickly bug The root of

As senior Android Development Engineer , Research on source code has become the only standard for them to improve their technology .

<> The only standard for improving technology

The author is also a Android developer , I had the honor to talk with Ali's senior architect , He said that at present, the questions our company likes to ask in the interview have they used those source codes , Have you studied the third-party library , Dig from breadth and depth .

I also know a lot of readers , Especially beginners are particularly resistant to looking at the source code , Here I explain why source code analysis is needed . These include the following benefits :

* study Android The source code helps us learn the design patterns , thought , framework .
* Familiar with the architecture of the whole source code , It helps us call more correctly Android Provided SDK, Write efficient and correct code .
* Learning the source code is helpful for our interview , Because big companies like to ask these questions .
* Learning the source code helps us learn some black technology , For example, when learning plug-in, we need to learn Hook
mechanism , But learning Hook We need to master the mechanism Activity Start up process , Message mechanism, etc .

Now more and more people are studying the source code , But many developers have a headache reading the source code : At present, there are all kinds of articles and blogs on source code analysis on the Internet , uneven , some good and some bad . Or messy , scattered , Fragmentation , I can't connect with it , Or the content is not deep enough , You can't learn dry goods . I happen to find that an Alibaba boss has sorted out such source code analysis , That's it 《Android
Development related source code compilation and analysis 》.

Fast start channel , Just scan the QR code below ( Free download ):

<>《Android Development related source code compilation and analysis 》 organization structure
