Learn to share
In the current era of information sharing, many resources can be found on the Internet, depending on whether you are willing to find or find the right method.
Many friends are not without information, most of them have dozens or hundreds of Gs, but they are messy and they don’t know how to look from where to look, or even forget after they look.
If you feel that the information you find on the Internet is very messy and out of structure, I will share a set of it with you. It is more systematic, and I usually study it myself.
The latest tens of thousands of pages of real interview questions in 2020
Seven module learning materials: such as NDK module development, Android framework architecture...
Only systematic and directional learning can quickly improve their skills within a period of time.
This system study notes is adapted to the crowd:
First, the learning knowledge is relatively fragmented, and there is no reasonable learning route and advanced direction.
Secondly, after several years of development, I don’t know how to go further, and I’m confused.
Third, at the right age, I don’t know how to develop, transform management, or strengthen technical research. If you need it, I happen to have why, don’t come to receive it! Maybe it can change your current state!
Furthermore, I am more confused.
