Preface
As a programmer, if you still don’t know anything in the face of new knowledge and new technology, and you still have a legacy of more than ten years ago, then you must be behind in knowledge and technology. If you fail to enter the management level, then you It will definitely be shot on the beach by the back waves of the Yangtze River.
Many programmers who are advancing with the times and good at learning are still the backbone of the industry. This just means that today's world has relied on one trick to travel around the world, and the era of life-long eating has passed. One must live and learn before he can walk in the world.
In my spare time at work, I will also turn over the interview questions of Dachang, so that I can always maintain the interview skills, and at the same time, I can understand the needs of Dachang for technology in order to prepare for emergencies, "Born in trouble, died in peace "The ancients don't deceive me.
Let me share with you a systematic growth and advancement route that I have summarized over the years of my own work, and share it for your reference.
A few years have passed, desktop development has basically died, now it’s Android development’s turn?
Have you noticed the difference between these? Desktop development is dead to the entire ecology, just like the real economy has turned to Internet shopping, the entire ecology is dead, resulting in all kinds of desktop development positions no longer recruiting people, making development, product, and operation must be original SEO optimization, looking for website traffic to move to the mobile terminal.
The current Android is different. It is not dead. On the contrary, the mobile Internet is now very mature, and with the advent of 5G, the opportunities will greatly increase.
So why do people think that Android development is not working? It's nothing more than the gradual transformation of native Android development, because Native development is time-consuming but cannot be cross-platform. It cannot be like RN\Weex\Flutter, writing the code once and running on multiple terminals.
Capital is profit-seeking. Gu Jiahui once said: Companies that are not profitable are all playing rogues. Faced with such an efficient production method, if you are the boss, would you not choose? Especially startup companies.
So the question is, why is there still Android Native development? Because it is native, all interactions and efficiency are the highest. For large companies, not only speed, but also APP operating efficiency and various indicators must be emphasized. Therefore, large companies are more inclined to Native development, while small companies are more inclined to rapid development.
Therefore, many small companies no longer recruit Android Native development, which leads to the reduction of Android native jobs. For beginners, small companies have few jobs and large companies can't get in. This is why training companies no longer train Android. This brings up the argument that Android is dead. So, it's not that Android is dead, it's that the threshold is high.
Now training companies like to train H5, and the promise of learning to ensure employment will never change. This is because the syntax of RN\Weex\Flutter is similar to H5. After learning H5, in addition to being able to do the original WEB development, the cross-platform language RN\WEEX\Flutter greatly increases the number of H5 positions, so H5 is not easy to learn. It is not because of its popularity, but its employment threshold is low.
Similarly, even if you enter the cross-platform development language from H5, do you think you don’t need Android native if you know RN\Weex\Flutter? It's just that the underlying architecture of Androd remains the same. Android native is always something to learn. All upper-level cross-platform applications are implemented by native controls. There may be exceptions to Flutter, but Flutter is written in the Dart language, and everyone does not, and don't look down on anyone, and Flutter is perfectly compatible with Android natively.
From the perspective of the nature of merchants' profit-seeking, cross-platform development is a trend. Even if RN\Weex\Flutter hangs any day, another cross-platform language will come out to dominate the world. In this world, the only constant is change.
Therefore, Android will not die, but the threshold of Android will increase. If you want to make a difference in the Android field, you need to understand cross-platform development in addition to Android native. If you are a newcomer, I suggest that after you understand the basic use of Android, you should focus on cross-platform development and study, and find a job first (except for those who graduate from school and enter large companies). If you are an Android practitioner, I suggest that you learn cross-platform languages to make yourself invincible forever, and don't wait until the day when the black swan comes, crying without tears. (The full name of the black swan is the black swan event, which refers to unexpected events that cannot be predicted at present)
Learn to share
In the current era of information sharing, many resources can be found on the Internet, depending on whether you are willing to find or find the right method.
Many friends are not without information, most of them have dozens or hundreds of Gs, but they are messy and they don’t know how to look from where to look, or even forget after they look.
If you feel that the information you find on the Internet is very messy and out of structure, I will share a set of it with you. It is more systematic, and I usually study it myself.
2021 The latest tens of thousands of pages of real interview questions
Seven module learning materials: such as NDK module development, Android framework architecture...
Only systematic and directional learning can quickly improve their skills within a period of time.
This system study notes is suitable for the crowd:
**First, **The learning knowledge is relatively fragmented, and there is no reasonable learning route and advanced direction.
**Second, **Development for several years, I don't know how to go further and I am confused.
Third , at the right age, I don’t know how to develop, transform management, or strengthen technical research. If you need it, I happen to have why, don’t come to receive it! Maybe it can change your current state!
