Is it ok to learn android development from startandroid?

Question

Java

Hello, I went through a lot of courses on android development, all of them were not very good, except for startandroid, everything is available and cool there. But the question is: "Actual is the course or not."

Answer 1

It is not normal to learn anything from any courses. Tutorials and official documentation are the only high-quality and effective means.

Answer 2

I recommend such Android development channels as:
Mobile Developer
Skill Branch
And if you know English:
Reso Coder
CodingWithMitch

Answer 3

It is normal to start with them, then you need to draw information from official sources and books. It is also useful to look at the source code.
As for the relevance of the lessons. Well, yes, some are outdated, some are very outdated. But this can be dealt with later.
