Reflection
I went to Beijing Dawanglu Ali for an interview last night, and had a serious sense of frustration, ashamed.
It’s better to have goals and ideals since college, and students who have been working hard to learn technology for their goals. The only thing that can be known in college is to participate in electronic design competitions and learn some embedded knowledge.
After graduation, I started to do android, said It’s better to call it a project. In fact, it’s just to move the code. How much do you really remember? When you move from Baidu to Google to your own code, you have to encounter the same problem several times before you can remember it. Many problems are not yet moved. I know why this is done. ReactNative has finished a project, and I can't remember the life cycle. What's the point of such work?
The progress is too slow. I taught myself Android in the first two years after graduation. Now I think I’m basically climbing. Two years later I think I’m very good, and I have done everything. In fact, it’s just a frog in the bottom of the well, and even Hybird doesn’t even know it. The interviewer asked "It's all native development", I stubbornly replied "Just write java and xml in Eclipse...", it's really ridiculous! Just like yesterday's answer to "How does the intent break through the parameter size limit": "I don't know how to do it." Breakthrough...". I can find excuses to say that the projects I usually do are not big and that these operations are not needed. When it is practical to intent, I should also take a closer look, don’t I? I think that my theoretical knowledge is not as good as BAT recruited in the past five years of work. For fresh graduates, maybe the novices who have been working in it for a year have more solid basic knowledge than me?

Other important knowledge points
Below are some advanced information compiled by several Android industry leaders corresponding to the technical points above. I hope to help you improve your technology. If you want to get it, you can comment [666] Get it for free~
Advanced advanced articles-advanced UI, custom View (partial display)
The knowledge of UI is currently the most users. The Android introductory training that was so popular that year, you can find a good job by learning this little piece of knowledge. However, it is clear that it is far from enough now. Reject the endless CV, go to the actual project in person, read the source code, and study the principle!
- Collection of interview questions
End of sentence
The junior engineer will start to do it directly when he gets the requirements, and then do it and find that there is a problem, either the technology cannot be realized, or there is a problem with the logic.
However, senior engineers will consider a lot when they get the requirements, the feasibility of the technology? Does it help the existing business? The impact on the existing technology architecture? How scalable is it? Wait...then the design coding stage will be carried out later.
And 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.
Through exchanges and discussions with friends in some industries, and refer to the current interview requirements of major factories. We spent almost a month sorting out all the knowledge systems that this Android senior engineer needs to master. You can see how much you have mastered.
Hybrid development, WeChat applet. All have to be learned and proficient
These are the cores of Android-related technologies, as well as advanced Java
Some techniques necessary for advanced advanced. Like mobile development architecture project combat, etc.
Android cutting-edge technology; including componentization, hot upgrades and hot repairs, as well as detailed technical systems of various architectures and frameworks
The above is the technical system we have compiled for Android senior engineers to master. Many friends may think that many technologies can be achieved by themselves, but some new technologies are not clear. There should be no big problem.
And this is precisely the problem! Why other senior engineers can exceed 300,000 years, but you only have a few hundred thousand?
It's because you only need to add what you think you need, but you don't know what the company needs. This is particularly easy to cause gaps. Because your technical system is not systematic, it is fragmented and scattered. So why do you break through 300,000 annual salary?
These words of mine are relatively straightforward and may poke some people's glass hearts, but I know it will definitely have a wake-up effect for some people. As long as someone finds a direction based on my advanced system outline and these words, and takes action to improve themselves, they will work harder to succeed. Then what I did all made sense.
If you like it, please help forward and like it so that more people in need can see it. Thank you!
I have all the technical information contained in the above system outline. You can share it with friends in need for free!
All of these have meaning.
