To put it bluntly, which industry is not eating youth? Regardless of the industry, most of the practitioners are betting their youth on tomorrow.
And the cruel fact is that no one’s job is irreplaceable. If you resign and the boss tries to keep it, it means that you are the cheapest candidate among the group of candidates to replace you.
The market is gradually maturing, and the prospects for programmers are indeed gloomy, which is not alarmist. But this statement is not objective, because most industries have this characteristic. The reason why I didn't see people from other industries jump out to talk about things, maybe it just shows that the programmer community has a high degree of introspection. Well, I just want to put gold on my face.
On the other hand, this also fully reflects the ability of programmers to build momentum on the Internet. For example, last year, the 996 project resounded on Github at home and abroad.
For those who want to advance to become a senior Android developer, I think the first step is to build your own knowledge system , organize the knowledge points you have mastered and the in-depth knowledge points you need to understand, and then expand your knowledge, not Blind and directionless learning, follow the trend and learn what technology is ``fire'' or ``hot''. Now that the big front-end is very hot, they give up native learning and cross-platform. In fact, **cross-platform, flutter development positioning, Neither is to replace native, but to expand skills and capabilities in native development. **The advancement of learning is a step-by-step process, and I have enough stock in my mind, and I will be more comfortable with learning new technologies and architectures.
So the following shows which systems Android advanced learning should touch! (The knowledge and technical points summarized in the picture are the focus and difficulty of learning Android nowadays, and there will be actual projects as a reference, you can compare which part of the study of a topic content, because the picture is too large, only the branches shown below are detailed The branch will not be displayed. If you need a complete Xmind system diagram, you can privately mail me to receive it.)
1. Essential skills for architects
2. Android framework architecture
3.360° performance tuning in all aspects
4. NDK module development
5. Interpretation of open source framework by design thinking
6. Architects become actual combat
7. Other
For some of the technical points of the above-mentioned knowledge mind map, there are special explanation videos to share, with a complete version of the [ System Outline ], and multiple sets of [ Dachang Interview Questions Analysis ] carefully organized from the Internet and corresponding to the content , for everyone to free Download, hope to help some people who are on the way to advanced learning Android.
How to do a good job interview surprise and plan the learning direction?
The interview question set can help you find out and fill up the vacancies, have a direction and targeted learning, and prepare for future entry into a large factory. But if you just read it again, don't study and delve into it. Then this interview question will be of limited help to you. In the end, we must rely on senior technical level to speak.
There are a lot of materials for learning Android on the Internet, but if the knowledge learned is not structured, and when you encounter problems, you just taste it and stop studying it in depth, then it is difficult to achieve real technological improvement. It is recommended to make a study plan first and associate the knowledge points according to the study plan to form a systematic knowledge system.
The learning direction is easy to plan, but if only through fragmented learning, it is very slow to improve oneself.
At the same time, I also collected and sorted out ByteDance in 2020, as well as interview questions from companies such as Tencent, Ali, Huawei, Xiaomi, etc., and sorted out the requirements and technical points of the interview into a large and comprehensive "Android Architect" interview Xmind (in fact, it is better than Expected to spend a lot of energy), including the knowledge context + branch details .
When building these technical frameworks, I also organized the system's advanced advanced tutorials, which will be much better than my own fragmented learning effect.

There are a lot of materials for learning Android on the Internet, but if the knowledge learned is not structured, and when you encounter problems, you just taste it and stop studying it in depth, then it is difficult to achieve real technological improvement. I hope that this systematic technical system will provide you with a direction reference.
Department, when you encounter a problem, you just try it out and don't study it in depth, so it is difficult to achieve real technological improvement. I hope that this systematic technical system will provide you with a direction reference.
