In 2022, we must enter the big factory as soon as possible
2022-07-06 05:05:00 【Android old skin】
2021 end of the year , Overheard the view of a big man in the industry : If you want to develop in China for a long time , Enter the big factory as soon as possible . The boss has experienced state-owned enterprises 、 foreign enterprise 、 Entrepreneurship and BAT, To the industry 、 Big factory 、 A technical insight , The evaluation is pertinent . Here's a brief summary of what you'll hear , Hope that in 2022 The beginning of the year , It is helpful for everyone in job hunting or job hopping .
- pattern . Big factories are bound to be pioneers in this field , In the big factory, we can see all kinds of volumes 、 level 、 The starting point under the mission and its significance to society . In small companies, focus on technical implementation , Optimize performance , In large companies, we also need to think about teamwork 、 Business development 、 Industry status . In this environment , We can not only get knowledge 、 Growth space , It's more about creating different patterns .
- value . Big factory rating is a clear measure of the value of a programmer , Every level of programmers in large factories and their treatment and ability are recognized by the society . An Ali P6 Tencent will never give you T5.
- grow up . Many people see the competition of big factories , See pressure , But I don't know the technology sharing of big companies every day 、 Technical precipitation of each project 、 The design idea of each middleware and the small partners around them can be the direction of their own learning and growth , And the people who have fought in the big factory are by no means mediocre .
- additional . The benefits of big factories , Confidence and status brought by big factories, etc , These may be physical , But it is what every worker cares about .
After the Spring Festival , Everyone will have a new beginning . Everyone wants a higher salary , Want to go to a bigger platform ,Android After a period of prosperity , The market is gradually calming down 、 mature , Relatively speaking, the pressure of sprint to big factories is also gradually increasing , It took a long time to collect and tidy up at home during the holiday Android Core technology points , Some documents were shared with the old fellow. , Whether it's preparing for job hopping or learning to accumulate strength , You can go to the card at the end of the article to scan the code for free .
One 、 The design idea interprets the open source framework
This summary study manual will Android Hot fix frame 、 Plug in framework 、 Componentized framework 、 Image loading framework 、 Network access framework 、RxJava Responsive programming framework 、IOC Dependency injection framework 、 Recent schema components Jetpack wait Android Third party open source framework integrated into a set of system knowledge notes PDF, Long 1042 page ! I believe that after reading this document , You're going to treat these Android The third-party framework is more in-depth 、 A more systematic understanding of .
This article contains knowledge points :
1、 Thermal repair design
2、 pluggable
3、 Component frame design
4、 Image loading framework
5、 Network request framework
6、RXJava Responsive programming framework design
7、IOC Architecture design
8、Android Architecture components Jetpack
Two 、Android senior UI Advanced decryption of open source framework
UI This knowledge is the most used today . It was hot for a while Android Introductory training , Learn this little knowledge and you can easily find a good job .
But it's obviously not enough now , Refuse endless CV, Go to the project in person , Read source code , Study the principle !
3、 ... and 、Android Framework Uncover secrets of development
as everyone knows ,Android It's based on Linux Implementation of the operating system . But for the Linux The kernel ,Android It's just an application that runs on top of the kernel , It's no different from other applications running on top of the kernel .
therefore Android Also need to run the environment , need Linux The kernel is loaded after booting Android Framework The resources needed to run . When Framework After the initialization, you can continue to start the corresponding APK Applications .
Main contents include :
Chapter one System startup process analysis
Chapter two Binder analysis
The third chapter Handler analysis
Chapter four AMS analysis
The fifth chapter WMS analysis
Chapter six PKMS Android10.0 Source code interpretation
Four 、Android Performance optimization and practical analysis
In the hands of development engineers at different levels , Because of the uneven level of technology , Even though many mobile phones are running, the software performance is very high , There is still stuck when opening the application .
in addition , As the product content iterates , More and more complex functions ,UI Pages are also getting richer and richer , It also becomes an obstacle to smooth operation . in summary , Yes APP Performance optimization has become a comprehensive quality that developers should have , It is also the guarantee that developers can complete high-quality application works .
5、 ... and 、Android Hundred framework source code analysis
As long as the programmer is , Whether it's Java still Android, If you don't read the source code , Just look at API file , It's just a matter of skin , This is not conducive to the establishment and completion of our knowledge system and the improvement of actual combat technology . This study manual contains Android Mainstream libraries, such as OkHttp、Retrofit、EventBus、ARouter Source code and so on , Have a detailed source code analysis .
6、 ... and 、NDK Module development
NDK It's a native development kit , This set of tools allows Android Use C/C++ Code , And provides a number of platform Libraries .
Main contents include :
- NDK Module development
- JNI modular
- Native development tool
- Linux Programming
- Bottom image processing
- Audio and video development
- machine learning
7、 ... and 、Flutter Learn advanced
In the past two years Flutter It's getting hotter , Whether in Ali or external companies , Participate in Flutter More and more people are engaged in ecological construction .Flutter As span end UI frame , There are also great possibilities in the future, such as Rax It is also built as a marketing activity page within the group DSL. So now study Flutter, Participate in Flutter Ecological construction is a fashionable and valuable thing .
The key points of this article are :
1、Flutter Overview of cross platform development
2、Windows in Flutter Development environment construction
3、 Write your first Flutter APP
4、Flutter Build and debug the development environment
5、Dart The basic grammar of grammar ( One )
6、Dart The use of the collection of syntax and source code analysis ( Two )
…
12、Flutter Medium widget
