    Default Android Development

    Ok... I am feeling like the Android API makes things way harder than they need to be (in some cases). For instance, can someone please tell me how to make a button? I can't figure out how to do it...

    I've tried this code but Eclipse says it can't find the variable 'id' in R.java. And, I don't understand how to instantiate a new button using Contexts. Help?

    public class AppLauncher extends Activity {
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            Button b = (Button)findViewById(R.id.button);
        }
    }

    Note: Using this.findViewById doesn't work either.
