Preface
1. Actively learn, strive to improve, and walk with social development
The longer you work in the workplace, the easier it is to form stereotyped thinking. This may be the effect of mental stalemate. This habitual thinking is one of the major reasons for reducing the living space of middle-aged people.
With the emergence of new industries and new technologies, if you want to not be eliminated by society, you must have iterative thinking, actively break through the inertia of thinking, accept new knowledge, and keep yourself away from the title of "old fritters" in the workplace. This kind of hard work will only make your path wider and wider.
2. Become into the circle and establish network resources
If you want to improve yourself, you must force yourself to join the circle you want to enter, so that you can meet different people and build the network resources you want.
3. Improve self-discipline and have health
Health is the capital of the revolution. Many successful people understand the importance of health, so no matter how busy they are, they will never forget to exercise. Ma Yun practiced Tai Chi every day, and Wang Shi jogged every day.
Although you are now 35 years old or are approaching 35 years old, as long as you don't let yourself go and stick to these three things, I believe you will not encounter the so-called mid-life crisis, let alone find a job.
I sorted out the computer today, and found the Anai Sutra that
I summarized half a month ago. I remembered the unpleasant Ali Er side a month ago, and I will share it with you today.
One side (all cities)
1. Click the icon, open the application, click the home button, re-enter, Activity life cycle callback
2. Service life cycle
3. Fragment when to use
4. Soft reference and weak reference, when to use weak reference?
5. What data structure is implemented inside LruCache? Maximum storage capacity?
6. How does activity convey information?
7. What kind of data can be transferred by the bundle?
8. What is the difference between parcelable and serialazible?
9. Binder bottom layer realization? How many times do you copy?
10. Android handler and looper source code?
11. The loop() method is blocked, why doesn't it affect the event distribution?
12. Android event distribution?
13. Which Android books have you read?
The second interviewer came up and asked: See you are learning Android by yourself, and you should have learned software-related courses too (the host specializes in communication). I: I have learned a little, but I have not learned enough.
Then asked these. . .
During the period, I asked questions about the internship. I answered halfway and said that the signal was not good. I changed the place and answered. After I asked me to answer the questions about the internship, I answered it again, and the interviewer said after I answered the question. If you talk briefly about the problems encountered in the internship, I will say it briefly again, and finally the interviewer said that he did not understand. . . I said or I would say it again, he said no. . . I feel that the interviewer is not an Android at all. . .
Two sides (I only remember these, I asked more than this)
1. Seven-layer model, what
does each layer do 2. The difference between http and https
http1.0 http1.0 http2.0 features and improvements
3. How to improve http, increase response speed, reduce request time (three methods are
mentioned ) 4. Difficulties encountered in internship
5. What is the stack in the operating system (no Yes )
6. Why should the memory be allocated in the stack (no)
7. What are the search algorithms (I said two)
8. What is the time complexity
9. What is the time complexity of the binary search
At last
**A zero-based rookie, I think persistence is the most important thing. **Many of my friends have come to me to study, and I teach them very carefully, but I can't stick to it in less than a month. I think there are two main reasons for their inability to persevere:
They plan to enter the industry not because of interest, but because of the so-called high wages in the IT industry, or they have no plans for the future at all.
It was really boring when you first started learning. It is really a test for you, so it’s not easy to stick to it, but if you are interested, you will not think it is tired or boring. In short, it’s still expensive to persist. .
Technology upgrade encountered a bottleneck? Lacking advanced Android advanced video learning to improve yourself? There are also a large number of interview questions from major companies to prepare you for the interview!
Click: Android learning, interview documents, video collection
Come to get learning materials to improve yourself to challenge the difficulties of BAT interviews
For many Android engineers, if they want to improve their skills, they often grow up on their own. The learning effect of fragmented systems is inefficient, long and helpless . The compiled knowledge graph hopes to have some reference for Android development friends and avoid detours. The focus of this article is whether you have gained and grown, and the rest is not important. I hope readers can keep this in mind.
No matter what difficulties we encounter, it should not be a reason for us to give up!
If you have any questions, you can directly private me, I will try my best to help you!

Finally, I wish you all newcomers to persevere and achieve success in your studies.
