foreword
The interview situation this year is not optimistic, the competition is becoming more and more fierce, and the difficulty of entering a large factory has increased. The market value of junior programmers is getting lower and lower, and it is difficult to find high-paying jobs even if they are struggling. On the contrary, senior programmers have been scarce in many companies and cannot recruit people. This creates two extremes. So many people are not optimistic about the status quo and prospects of Android development.
It's not just Android. In fact, if you don't keep learning and improving yourself in the programming industry, it's only a matter of time before you get eliminated. Why is there the sadness of middle-aged programmers? When you are in your 30s and 40s, if you don’t climb to a high enough management level, even if you are skilled enough and experienced enough, will those companies hire you? This is unhealthy in the current industry, but instead of complaining when we enter this industry, we might as well accept it and make changes.
So for us, what is the direction to change the status quo? I will tell you with certainty that you only need to confirm one direction at present, which is to become a senior Android development engineer as soon as possible.
What is an Android Development Senior Engineer
Android development senior engineer, in fact, the definition is relatively vague. Many friends don't even know what a senior engineer is. Tonight, many people in the group asked, what is a senior engineer? What is the difference between a senior engineer and an ordinary engineer?
When it comes to senior engineers, everyone's first impression is naturally that they have rich work experience and excellent skills .
Note that the work experience mentioned here does not refer to the working hours.
Some people work on projects in a down-to-earth manner. In their spare time, they want to learn more new technologies, insist on reading, write blog summaries carefully, practice more, and their own understanding is not bad. In 2 or 3 years, they can have 3 or 5 years of work experience from others, and they can grow into senior engineers of the company.
And some people dawdle , do projects that pass by, play games and watch dramas in their spare time. Maybe you have worked in the company for 10 years and seem to be conscientious, but you have no higher requirements for yourself.
So it is not how many years you have worked to become a senior engineer. This is a wrong idea, otherwise why so many older programmers are optimized every year. Is it really old?
Junior engineers will start working directly when they get the requirements, and then find out that there is a problem, either the technology cannot be realized, or there is a problem with the logic.
And senior engineers will consider a lot when they get the requirements, the feasibility of the technology? Is it helpful to existing business? Impact on existing technology architecture? How scalable? And so on... and then the design-coding phase.
What prevents your annual salary of 30W+
Now with the popularity of cross-platform development, hybrid development, and front-end development, the technologies that Android developers need to learn and master are also increasing.
Many friends think that they know many technologies, but they just don't know some new technologies . It shouldn't be much of a problem.
And that's exactly the problem! Why can other senior engineers break through 300,000 years, but you only have a few hundred thousand?
Just because you only need to add what you think you need, but you don't know what the business needs . This is particularly likely to cause a gap. Because your technical system is not systematic, it is fragmented and scattered. So why do you break through 300,000 annual salary?
So you, a senior engineer, do you think you are? Can you become a senior engineer even if your own technical system is scattered?
These words of mine are relatively direct, and may poke some people's glass hearts, but I know it will definitely wake up some people.
To become an advanced developer, your technical system must be systematic, not fragmented or scattered.
So how can we advance from ordinary programmers to advanced programmers?
1. Improve the ability of code optimization: "Code can run" is by no means the end for an excellent programmer, but the beginning. Excellent programmers must be familiar with various algorithms and data structures, use them flexibly, and devote themselves to writing simpler and more efficient programs.
Second, think first and think more: programming ideas are systematic plans and assumptions, and are the order and clues for programmers when writing programs. Programming ideas are systematic plans and assumptions, and are the order and clues for programmers when writing programs.
3. That is what I said earlier, a programmer without a complete technical system can never become a senior engineer.
So any systematization of messy, scattered, and fragmented knowledge, many people have no clue.
It doesn't matter! ! !
It doesn't matter! ! !
It doesn't matter! ! !
Here I would like to share with you a set of "Advanced Information on Eight Modules of Android" written by senior architects of Ali, to help you organize the messy, scattered and fragmented knowledge systematically , so that you can systematically and efficiently master the various knowledge points of Android development, and become a senior engineer as soon as possible.
Due to the large content of the article and the limited space, the information has been organized into PDF documents. If you need the complete document of "Android Eight Modules Advanced Information", you can add WeChat to get it for free!
PS: (At the end of the article, there is also a small benefit of using the ChatGPT robot!! Don’t miss it)
"Android Eight Modules Advanced Notes"
Compared with the fragmented content we usually read, the knowledge points of this note are more systematic, easier to understand and remember, and are arranged strictly according to the knowledge system.
Full set of video materials:
At the same time, a WeChat group chat robot based on chatGPT was built here to answer difficult technical questions for everyone 24 hours a day .
