Preface
The current terminal development has begun to enter a stable period. At this stage, the pressure of large manufacturers is very high, and large and small factories will be squeezed. The apps people use are becoming more and more fixed. It can drain hundreds of thousands, and these effects are getting smaller and smaller now. Especially this year, it is basically impossible to suddenly appear in Top100's pp from an unknown team.
1. [Byte Beat a full set of advanced learning materials] Nine topics:
1. Advanced UI, custom View
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.
But obviously it's not enough now. Reject endless CV, go to the actual project, read the source code, and study the principle!
2. NDK development
Audio and video, artificial intelligence, these are the development trends that cannot be blocked in the future. We can see those recruitment positions on Liepin.com, and the salary required to be proficient in NDK is 30-60K+. Don't miss out for those who are pursuing high-paying positions
3. Data structure and algorithm:
Bytedance interview, but the algorithm was rejected. Just want to change to a big factory that does not require high algorithms?
As a result, I went to Alibaba, Tencent, Huawei, Xiaomi and other companies for interviews, but they were all rejected!
4. Java kernel principle
100%, all companies big and small, interview must ask
5.Flutter
It's been more than a year, you don't have to use it for work. But if you go out for an interview (the junior level rarely asks for it), you will definitely ask.
Regarding whether Flutter is the future or not, I can’t tell you for sure. All I can be sure of is that you are going to interview for high-paying positions, and you have to master this mainstream new technology. Learning ability.)
6. Performance optimization
I heard that the last elimination system of large companies is specially prepared for employees with poor code quality and low performance. How to write high-performance code? How to perform performance tuning?
7. Mobile Architecture Practical Project
Architects are not born, they are honed in the project. Therefore, we need to combine the project for practical training when we learn the technology. Then the most commonly used architecture in Android is nothing more than MVC, MVP, MVVM, but if these ideas Mixed with modularity, hierarchy, and componentization, it is not that simple.
8.
Why should Kotlin learn Kotlin?
- Google announced that 35% of Android professional developers currently use kotlin (explosive growth)
- The grievances between Google and Oracle stemming from Android have lasted for a long time, and they have always wanted to find a language to replace Java.
- Java will start charging in the future, which may cause some companies to give up Java
- There are already many recruitment requirements of companies that require developers to know Kotlin
- The cost of learning kotlin is not very high. The conversion from Java to kotlin is usually enough to complete in one week, and kotlin and Java can call each other. If kotlin can't solve the problem, you can still use Java to write (very user-friendly)
2. Android core knowledge notes
A total of eight module learning materials: such as NDK module development, Android framework architecture, flutter, kotlin...
Only systematic and directional learning can quickly improve their skills within a period of time.
This knowledge system is suitable for all Android programmers to learn. There are detailed explanations and introductions about the knowledge points in the above catalog. Mastering all the content of this knowledge point will give you a qualitative improvement, and it also summarizes many interview processes A summary of the questions encountered and the corresponding answers.
