Answer 1

As far as I understand, you are not familiar with programming at all? Start by reading the literature:
1) forcoder.ru/java/head-first-java-1127
2) forcoder.ru/java/head-first-programmirovanie-dlya-...
3) As a practice, choose an application (multiple applications ), which would be interesting to develop, even if there are many analogues of your idea, it doesn’t change anything, you need practice, a lot of practice.
4) Read on WEB development forcoder.ru/web-other/head-first-servlets-and-jsp-1128
will interact with this server, for example, using websocket technology.

Answer 2

I would recommend you a book "The busy coders's guide for Android". It updates every six months (or more often), let you chat with it's community and be aware of all Android programming news.
If you understand above text, you have enough english level to read this material.
