How much Java knowledge is required for Android development

Question

Java

(I studied Java at the university (1.3 or 1.4 then), coded under C ++ / QT / MFC / WINAPI for myself)

Do I need only Java itself or is it also useful to know some standard libraries from Java in addition?

What literature would you recommend to refresh your knowledge?

Answer 1

For the eyes enough basic knowledge of Java, or good knowledge of another language. + necessarily high ability to google. After 4 years of PHP, I got into the process without any problems, while I never wrote anything in Java.

Answer 2

In order to nagovnokodit something, you can know the very basics. In order to write something worthwhile and of high quality, core in full + android api.

Answer 3

Far from all of the standard Java libraries work in Android (but their number increases with the growth of the API), I would recommend learning Android right away, the rest will come to mind.
One of the best books:
Pro Android 2 - Sayed Y. Hashimi, Satya Komatineni, Dave MacLean

Answer 4

I can’t say anything about what is needed for Android development, but to refresh my knowledge I can recommend Oracle Java Tutorials: download.oracle.com/javase/tutorial/index.html

Answer 5

You can read more mana on the Android SDK website

Answer 6

You only need to know the basics of programming for any language (well, except for BASIC =)
I wrote an application for Android without any problems, nothing complicated.
* Well, not entirely without problems, the syntax of Java is buee, IMO.
