preface

BAT, as the three major Internet companies, is the heart of countless fresh graduates to cut their heads. Not only because of the loud signboard, and in the Internet era advanced experience and technology are desirable. Today xiaobian to bring an article, from a program ape in Ali work for a year on the componentization architecture practice experience and sharing, I believe you will have a great harvest after reading.

It’s been 13 years since Android was released in October 2008. Developers have gone from Android 1.0 to Android 11, and Android 12 is coming soon… In the process, we have experienced a lot.

Why componentization?

When it comes to measuring how good a developer is, interviewers will look at what he can do and what he can do. If you are a beginner in the industry, the company will not ask too much of you.

But there are too many “novices” in the Android industry with 3-5 years of experience. How do they typically develop? The architecture is unstructured, the code is undesigned, and the performance experience is unexciting.

So we will find that the level of high and low, can be completely measured by the code is good or bad. For developers, the first step in writing good code is to choose a good architectural design.

The most popular architectural pattern in the Android industry right now is componentized development. Why is that?

1. Componentization is a must in all projects of big factories. 2. Componentization is also a must for team development. 3. Componentization is also a must for junior, intermediate and advanced developers. 4. From the perspective of maintenance for large projects, componentization is a must. 5. Componentization is still necessary to improve development efficiency.

Traditional APP architecture diagram

  • Traditional APP architecture diagram

  • As shown in the figure:

In the widely used Android APP technical architecture, there is usually a large amount of business logic in one interface, which is full of various network requests, data operations and other behaviors. There is no concept of modules in the whole project, only simple folders divided by business logic. And businesses are directly called to each other and highly coupled together. Business relationships under a single engineering model are, in general, interdependent and inseparable. The diagram below:

  • Componentized architecture diagram

Business components are independent and not related to each other. In the integration mode, these business components are libraries, which are dependent on the APP shell project and constitute an APP with complete business functions. However, in the component development mode, business components become applications. They can be developed and debuggable independently, and because in component development mode the amount of code the business components use is far less than the full project, they can significantly reduce compile time at runtime.

But the problem is that many developers have never touched componentized development before, so how do we master this technology?

Xiaobian carefully sorted out the former Ali P7 mobile architect Teacher Zero “advanced Android componentization strengthen actual combat (with source code)” materials, take you step by step handwritten Ali ARouter componentization routing framework, master componentization development, so that you can really put the componentization applied to their own projects.

conclusion

The importance of componentization development does not need me to elaborate too much, in a word, if you want to enter the Internet industry, want to be promoted in the gold three silver four pay rise, this “advanced Android componentization strengthen actual combat (with source code)” must be essential!
