If you want to stand out among Android developers, you must understand performance optimization.

Preface

As we all know, mobile development has entered the second half. In order to stand out among many developers, we need to have in-depth research and experience in a certain field. For Android developers, there are currently several good subdivisions. It is worthwhile for us to establish our own technical barriers, as follows:

• 1. Performance optimization expert: capable of in-depth performance optimization and systematic APM construction.
• 2. Architect: Has rich experience and experience in application architecture design, and has a thorough understanding of the implementation principles and architecture design of the Android Framework layer and popular third-party libraries.
• 3. Audio, video/image processing experts: There is no doubt that mastering NDK and delving into the fields of audio, video and image processing will allow us to shine in the next few years.
• 4. Big front-end expert: A deep understanding of Flutter and its design principles and ideas can give us the ability to quickly learn front-end knowledge.

Among the above-mentioned subdivisions, the most difficult and technical barrier is performance optimization. To become a top performance optimization expert, you need to have in-depth understanding and research of in-depth knowledge and breadth of knowledge in many fields. Among them There is no shortage of skills involved in architect, NDK, and Flutter that need to be mastered.

Clear future direction

We are no longer in the early days of the development industry. At that time, developers only needed to understand four major components: activity (ACTIVITY), service (SERVICE), broadcast receiver (BroadcastReceiver), content provider (Content Provider), Java If you have a certain understanding of the basics and other related knowledge, you can easily find a job, but now this method is obviously no longer feasible.

As various component libraries become more and more mature, there are more and more relevant learning materials, and more and more information is obtained; we increasingly don’t know how to find our future direction, so what should we do? What about improving yourself? How to find the information that really suits you among so much information? How can we clearly see the direction of this era?

Many people are moving forward slowly in confusion. They often feel anxious and feel that they cannot make progress and reach higher positions. They also think that the requirements of big companies are too high and the interviewers are always making things difficult for them. But you have to understand Progress means elimination

Only by examining the underlying principles of Android performance optimization can the interviewer truly understand whether your abilities are suitable for this position , and thus be able to better judge whether you have the ability to advance to a higher level of Android developer . Only true If you have a clear understanding of your current situation and can actively improve yourself, then you will definitely have your own place among many Android developers .

So when it comes to performance optimization, we have specially prepared for you this " Full Analysis of the Practical Practices of Android Performance Optimization Major Manufacturers ", which contains the practical performance optimization practices of major manufacturers such as Tencent, Baidu, and Byte , which can not only consolidate the underlying principles and performance adjustment Excellent core technical points, and able to master architectural design methodologies that are difficult for ordinary developers to touch. Let you have core competitiveness that is difficult to copy by your peers at work, in a team, and during interviews.
