On studying Android

Question

What is the best way to learn Android? I'm reading Rogers's at al.'s book Android Application Development. However, as I tried the following code, nothing outputs except a mobile phone:

package org.qwerty.com;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class HelloWorld extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView tv = new TextView(this);
        tv.setText("Hello, Android");
        setContentView(tv);
    }
}

I tried also search for the Dalvik Debug Monitor http://stackoverflow.com/questions/1108820/android-emulator-output but I couldn't find the option where I can open my hello android project.

The "Professional Android Development" from Wrox by Reto Meier is in my opinion the best book to start learning Android from. Besides the Google documentation
