Android development tutorial! 2021 Jingdong's latest Android interview real questions analysis, the interviewer series!

Many programmers have this kind of consciousness; job-hunting education is a stepping stone. Without 211,985 starting education, it is impossible to enter a large company.

Let me give you an example;

If you are an interviewer from a big factory, there are 10 general school freshmen who have just graduated without work experience and 10 985 freshmen who have just graduated, and you only plan to recruit 5 internships.

Do you look at academic qualifications or ability?

I think normal interviewers will choose a good degree. Because before you work, your academic qualifications largely represent your abilities

How to become an Android architect?

Build your own knowledge framework, comprehensively upgrade your own technical system, and delve into the underlying source code.
Most technical people like to use mind maps to build their own knowledge system, which is clear at a glance. Here to share with you a mainstream Android architect technology system of major manufacturers, which can be used to build your own knowledge framework, or to check for omissions;

Corresponding to this technical outline, I have also compiled a complete series of video tutorials for Android senior architects, mainly for students who have more than 3-5 years of Android development experience and need to learn and improve at the senior architect level. Click here to share for free. , I hope to help you break through the bottleneck and move into a big factory;

Finally, I must emphasize a few points:

1. Building a knowledge framework does not mean that you organize the sequence of knowledge to be learned, and then you can copy and paste it after reading and understanding. Most of them require you to read the source code and principles by yourself, and you can write it by yourself.
2. When studying, you must watch and practice several times to get the knowledge thoroughly and take notes. These are very important! In the end, what level you reach depends on how much knowledge you have digested
. 3. In the end, your knowledge framework should be a complete technical system that takes both breadth and depth into consideration. Then you can reach the level of senior architect after many projects and gain experience.

You just need to fill yourself in this big framework. The annual salary of 40W is definitely not the end, and the technology is endless
