Android Bluetooth development! Five steps to get Android development environment deployment, successfully join Ali

1. Write on the front

To become an excellent Android developer, you need a complete knowledge system. Here, let us grow together to be what we think.

The early approval of the 2020 Autumn Recruitment is almost over. At present, the Android development posts have received offers from [Baidu], [Byte Beat], [Meituan Dianping], and [NetEase], all of which are in the direction of Android development. There is still some time before graduation defense, to write about my path to career change on the Internet.
Let me introduce my background first. Beihang University has a bachelor's degree and a master's degree. There are two subject competition awards and one SCI.
In terms of computer, there is no internship, only a slightly related project can be written in the resume. Professional knowledge depends on self-study, so the process is also extremely painful. The preparation time starts from the winter vacation in 2019 and ends at the end of August 2020, with a span of less than one year.
During the autumn recruitment period, a total of more than 20 resumes were posted on the Internet, 8 written examinations, 9 interviews, and 5 units gave clear intentions for hiring. The final results were better than their expectations.

Android basics & commonly used

• For Android basics & common knowledge, I think that for junior developers, the most important knowledge points according to priority mainly include: four major components, layout usage, multi-threading & animation ;
• The details are as follows:

---

2. Android Advanced

For the advanced knowledge of Android, the main knowledge points according to the priority mainly include: custom View, performance optimization , the specific introduction is as follows:

---

3. Keep up with the times, popular technologies

• In addition to basic Androidknowledge for daily use , we also need to always pay attention to industry trends and learn new technologies keeping pace with the times. For example, the more popular Androidemerging technologies in recent years include: Flutter, hot repair, plug-inization, etc.;
• At the same time, it is also very important to understand & learn commonly used open source libraries. Commonly used open source libraries mainly include open source libraries for image loading, network requests, and asynchronous processing . The specific types are as follows:

---

4. Programming language: Java and Java virtual machine

• AndroidIs based Javaon, so learning Javaand Javavirtual machine ( JVM) are very important
• For learning Java, our mobile development and learning Java do not need to be as deep as the back-end. I think as an Android developer, the content of learning includes: language features, basic usage, collection classes & mechanisms . The details are as follows:
  

People who are emerging in recent years Kotlincan also learn about it, but I don’t think it will completely replace it in a short time.Java

• For the Javavirtual machine ( JVM), it belongs to the underlying & principle content. The specific introduction & learning content includes:

---

5. Computer Basics

• In addition to learning Android specific technology, for programmers, basic computer literacy is also very important, that is, the basic knowledge that all programmers in the technology industry should have.
• Computer foundation mainly includes: data structure, algorithm and computer network, the specific introduction is as follows:

---

6. Extra

• After you have learned the above knowledge, you should be able to be regarded as an intermediate Android development engineer, you can try to advance to the senior Android development engineer.
• At this point, I think there are 3 directions to try: technical experts, architects & management , the details are as follows:

---

7. Summary

At this point, the introduction of Android theoretical knowledge & Android knowledge graph to be learned is finished, and a brief summary is made below:

study Exchange

If you feel that your learning efficiency is low and you lack correct guidance, you can join a technical circle with rich resources and a strong learning atmosphere to learn and communicate together !

There are many front-line technical experts in the group, as well as code farmers who are struggling in small factories or outsourcing companies. We are committed to creating an equal, high-quality Android communication circle. It may not be possible to make everyone's technology advance by leaps and bounds in the short term. In the long run, vision, pattern, and long-term development direction are the most important.

The 35-year-old middle-aged crisis is mostly caused by being led by short-term interests and squeezing out the value prematurely. If you can establish a correct long-term career plan from the beginning. After 35, you will only be more valuable than those around you.

The direction is the most important.
