Learning journey
It’s been a long time since I started learning android on the first day. In the process of my own learning, I also felt the charm of exploring knowledge. I also enjoy my learning process and the accumulation from scratch.
The field of Android may be considered a relatively unfamiliar field to me. The only place that may be considered relevant is probably that I have learned the basics of Java and know a little bit of Java programming, but it is not very proficient.
But when I first started contacting Android, although I didn't quite understand the operating theory, when the code I wrote was displayed on the phone, I seemed to open a new world. I started to want to understand this subject, I want to learn how to make a page on a mobile phone perfectly, and learn how the functions on a mobile phone are realized.
After studying for a period of time, I gradually understood the basic operation of this course and some of its skills. I have also improved in the learning process, and I hope that in the next learning process, I can become more and more comfortable.
