The current state of Android development
At present, mobile development is already at a saturation stage, and Android development is not as popular as it was then, and it is no longer as popular as it was a few years ago. Just as a programming language has experienced its peak, then there must be such a curve, like the sine curve we learned, first rises rapidly, then reaches the peak, then falls, and finally approaches a stable value.
It can be seen that starting from the second half of 2016, the mobile Internet is basically in a stage of slow development. Many bigwigs call it the second half of the Internet. If the first half of the mobile Internet is an extensive and strong turf stage, then the second half is the stage of defending the turf. At this stage, there will be many oligarchs.
Technically, compared to the previous interview, only the four major components of Android were asked. The database, network and project experience are different. Now the interview for Android positions will design various principles (including some principles of the system and principles and processes of third-party libraries), Android Optimization and cross-platform technology related to Android. In addition, slightly larger companies will also require App user experience, fluency, etc., so Android interviews are no longer the same.

Facing the impact of cross-platform technology, everyone knows the status quo of native developers. I believe that most of the interviewers have this experience, the requirements are getting higher and higher, and more and more technologies have to be learned and mastered!
So, what technologies do we need to learn to master? We might as well take a look at the current enterprise requirements for Android senior engineers.
This is the recruitment requirement of Chinasoft on Zhaopin.com. I framed the key points for everyone;
That is to say, if you want to be stable or develop well in the Android industry now, in addition to the previous Android development system, you must at least know the ones mentioned above.
In order to facilitate everyone to have a clear concept, I will send out these frameworks together.
1. Have a solid foundation of Java programming. The foundation is very important to a person's growth height. The cliché and image can be compared to the foundation of a tall building.
2. Familiar with mobile framework and tools to improve development efficiency
3. Proficient in APP overall performance tuning and code framework optimization
4. NDK module. Like the very popular artificial intelligence now
5. Mixed development and actual project combat. Cross-platform hybrid development apps are favored by enterprises because of their low development cost and the advantages of experience effect numbers, and hybrid development has become a general trend. Those who do not learn from actual combat operations are all on paper;
There are also some technologies such as front-end and WeChat applets that need to be added to the system. All the examples are not complicated.
Finally, talk about my learning route
In fact, it is very simple. The picture below contains all the knowledge points that Android needs to learn. There are 8 major sections:
- Essential skills for architects
- Android framework architecture (advanced UI+FrameWork source code)
- 360°Android app full performance tuning
- Interpretation of open source framework for design thinking
- NDK module development
- Practical link of mobile architect special project
- Mobile architects must learn WeChat applets
- Hybrid development of flutter
Android learning materials
As for me, I systematically made a copy of the materials and videos of the learning system for the branches of the above eight major sections. About the following, I will not write all of them, otherwise it will be too long and affect everyone's reading. If you need it, you can send a private message to me [Advanced] I will share it with you for free, or click the link below to receive it. Thank you for your support for so long.
Android learning PDF+architecture video+interview document+source notes
If you have other needs, you can also view it on GitHub, and the following information will be uploaded to Github one after another
330 pages of PDF Android learning core notes (including the above 8 sections)
Android learning system corresponding video
to sum up
I hope to use my own learning methods to help everyone improve their skills:
-
1. Read more books, look at the source code and do projects, and usually summarize
-
2. You can't stay in the use of some basic apis, you should study in a deeper direction, such as the internal operating mechanism of activity and view, such as Android memory optimization, such as aidl, such as JNI, etc., not just staying in the use, But by reading the source code, understand its implementation principle
-
3. At the same time, there are certain requirements for the architecture, the architecture is abstract, but the design pattern is specific, so we must strengthen the learning of the design pattern
-
4. Android has many directions, advanced UI, mobile architect, data structure and algorithm, and audio and video FFMpeg decoding. If you are more interested in one of them, you can boldly advance!

I hope everyone likes, reposts, comments and attention, your support is my motivation to continue! Come on!
