How much Java should I have learnt before trying Android programming? [closed]

Answer 1

Go give it a try! I find it best to learn programming languages doing real world example, and if Android keeps your interest it is probably a great example.

Answer 2

Try it and see - only you can answer that. If you start and find it difficult, you don't know enough. It'll actually be a good motivation to continue learning Java. I'd go for it.

Answer 3

do I know enough about Java now?

Yes

Can I start programming Android yet?

Yes

how much Java I need to know before Android?

A complete understanding of the basics would be desirable.

Specifically the following topics:

• Declarations and Access Control
• ObjectOrientation
• Assignments
• Operators
• Flow Control, Exceptions, and Assertions
• Strings, I/O, Formatting, and Parsing
• Generics and Collections
• InnerClasses
• Threads

But if you know already the basics ( classes, objects, inheritance, interfaces ) I think you're ok to start.

You don't need to learn specific libraries ( like swing, or others ) because you won't use them in Android.

Answer 4

I jumped right into Java and Android at the same time knowing basically nothing about either. I had about 2 years experience with C doing homebrew for nintendo DS so nothing was really OOP and it was all single threaded.

Since you know what you do of Java, I'd say you'll be fine. The bottom line, is that slow is good. Take it easy, take it slow and don't skip ANYTHING. The provided developers guide is very solid, covers all of the important concepts. An early piece of advice... don't block the UI thread... If you're going to write a game pay special attention to how to create a proper game loop thread. There's really not a lot on that provided by Google (except for SDK example games) but there's information out there.

Answer 5

What you really need of Java is syntax and capabilities. You don't need to know specific API that you will learn with Android anyway.. so I think you can go with Android easily.

Actually you could just learn Java along with Android without any problems..
