Android development army vast, after nearly ten years of development, Android technology optimization day by day new, now Android 11.0 has been released, the performance of the Android system has been very smooth, can be fully comparable to iOS experience.

However, to the hands of the major manufacturers, to change the source code, custom system, so that the Android native system becomes mixed, and then to the hands of different levels of development engineers, because of the uneven technical level, even if many mobile phones in the running software performance is very high, open the application is still stuck.

In addition, as product content iterates and features become more complex, the UI pages become richer, which can become a barrier to smooth operation. To sum up, APP performance optimization has become a comprehensive quality that developers should have, and it is also a guarantee that developers can complete high-quality application works.

To this end, I put ali, Tencent, Bytedance, Meituan and other companies Android performance optimization practice integrated into a PDF document, due to too much content, I first introduce the practice part, and then introduce the theory part.

1. [Bytedance Advanced Learning Materials]

1. Advanced UI, custom View

The UI piece of knowledge is the most widely used today. That year the popular Android training, learn this small piece of knowledge can casually find a good job.

But obviously now is far from enough, refused to endless CV, personally to project combat, read the source code, research principle!

2. The NDK development

Audio and video, artificial intelligence, these are the future development trends cannot be stopped. We can look at the recruitment positions on Liepin.com and the salary required to be proficient in NDK is 30-60K+. If you’re looking for a high-paying job, don’t miss it

3. Data structure and algorithm:

Bytedance interview, algorithm failed and was rejected. Just want to change to a big factory with low algorithm requirements?

As a result, I went to Ali, Tencent, Huawei, Xiaomi and other companies for interviews, only to be rejected!

4.Java kernel principle

One hundred percent. It’s a must for all companies, big and small

5.Flutter

It’s been burning for over a year. You don’t need it for work. But when you go out for an interview, you will be asked.

I can’t tell you whether Flutter is the future. What I can tell you is that you need to be able to master this mainstream new technology if you are going to interview for a high-paying job. (What big factories value most is your ability to learn besides basic and technical level.)

6. Performance optimization

I’ve heard that big companies have a last-place elimination system for employees with poor code quality and low performance. How to write high-performance code? How do you tune performance?

7. Mobile architecture practical project

Architect is not innate, is given in the project, so, we learn the technology needs to be combined with the project actual combat training, then the architecture of the most commonly used is not in the Android MVC and MVP, MVVM, but if these thoughts and modular, hierarchical, modular mixed together, then it’s not an easy thing.

8. Why does Kotlin learn Kotlin?

• Google announced that kotlin is now used by 35% of Android pro developers (explosive growth)
• Google and Oracle have long been at loggerhead with Android and trying to find a language to replace Java
• Java is going to start charging, which may cause some companies to abandon Java
• There are already many companies that require developers to know kotlin
• Kotlin learning cost is not very high, from Java to Kotlin, generally enough to complete a week, and Kotlin and Java can call each other, think kotlin cannot solve, still can use Java to write (very user-friendly)

Ii. Android core knowledge notes

Learn about NDK module development, Android framework architecture, Flutter, Kotlin…

Only systematic and directed learning, in a period of time to quickly improve their own technology.

This knowledge system is suitable for all Android programmers to learn, there are detailed explanations and introductions about the knowledge points in the above directory, master all the content of the knowledge points will have a qualitative improvement for you, which also summarizes a lot of questions encountered in the interview process and have the corresponding answer summary.

The last

Now it is said that the Internet winter, in fact, is nothing more than you get on the wrong car, and wear less (skills), if you get on the right car, their technical ability is strong enough, the company will cost a lot to replace, how can you be fired, are the elimination of terminal business Curd! Now the market is flooded with junior programmers, this tutorial for Android development engineers 1-6 years of personnel, is in a bottleneck period, want to break through their salary after the year, advanced Android senior, architect for you is like a duck to water, hurry up to get it!

The above [HD Technology Brain Map] and [accompanying architecture technology PDF] click:Android Architecture video +BAT Interview topics PDF+ Study notes, or private reply [skill improvement] can be obtained!

The reason why someone is always better than you is because they are already better and are constantly trying to become better, while you are still satisfied with the status quo and secretly happy!

The road to being an Android architect is a long one.
