Do you need a "complete" understanding of Java to program Android Applications? [closed]

Question

I am looking to start developing applications for Android and i was wondering if you could fill me in on the know how's and the requirements on a technical viewpoint.

I have the SDK, Eclipse and Java installed and even a handset to "real" test on.

My question is being a complete amateur to Java and having never used the language how much java would i have to learn to develop Android Applications ?

Answer 1

I would say you can just start with some tutorials the same way you would when starting with just Java. You'll learn along the way, just use a lot tutorials.

There is not much difference for the language, but there is a great difference in the framework, ie. the way you set up applications.

So just Java you would learn:

public static void main(String[] args){
    System.out.println("Hello World");
}

In Android it would be:

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    System.out.println("Hello World");
    // Or:
    Log.v("MyActivity", "Hello World");
}

to print "Hello World" to the console respectively the log.
