code errors copying from a book

The code comes from "Hello Android" Page47.

I am using 1.6 since that is what the book is written for.

import android.os.Bundle;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;

    /** Called when the activity is first created. */

e1  @Override
e2  public void onCreate(Bundle savedInstanceState){

    // Set up click listeners for all the buttons

error message e1

the annotation @override is dissallowed for this location

error message e2

Multiple markers at this line - Syntax error on token(s), misplaced construct(s) - Syntax error on token "void", @ expected - Syntax error on token ")", = expected

I have no idea whats wrong. The code is identical to the code in the book. I'm sure. TIA

Answer 1

Firstly, are you sure the book is written for Java 1.6? I'm pretty sure Android is designed for 1.5 compatibility.

Anyway, the reason for both errors would appear to be that you have placed the onCreate method outside of a class body.

Between the import statements and the first comment, there should be a class declaration like:

public class MyActivity extends Activity

Download the code from Hello Android's Official Website to get a for-sure working version. You can also check the errata.

android - Using icons from system versus copying them into your project

And if using the system ones is better, how do you access them in XML? Thanks!
