<p>Welcome to the Android Developer Guide! The <strong>Dev Guide</strong> is your conceptual and practical
introduction to developing applications for Android. With this guide, you're free to explore 
which ever topics interest you, based on your goals and experience.</p>

<p>If you're new to Android, you're probably wondering what it takes to 
write a "Hello, World" application. So here it is:</p>

<pre>
package com.example.hello;

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

public class HelloWorld extends Activity {

   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       TextView tv = new TextView(this);
       tv.setText(&quot;Hello, World&quot;);
       setContentView(tv);
   }

}
</pre>

<p>That's the only code you need to write!</p>

<h2 class="small-header">Not convinced?</h2>
<p>If you're still shouting "Show me the code!" then take a look at
more Android code in the <a href="{@docRoot}guide/tutorials/hello-world/index.html">Hello World Samples</a>.</p>
