I am attempting to follow the Google Map View under the views tutorial for the Android. I have followed step by step but still only see grey blocks when viewed.

First: I created a Virtual Device using "Google API's(Google Inc.) Platform 2.2 API Level 8" Second: When creating my project I selected "Google API's Google Inc. Platform 2.2 API Level 8". Third: I obtained the SDK Debug Certificate Fouth: Began Coding. Main.xml

<?xml version="1.0" encoding="utf-8"?> 
<com.google.android.maps.MapView 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/mapview" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:clickable="true" 
android:apiKey="0l4sCTTyRmXTNo7k8DREHvEaLar2UmHGwnhZVHQ" 

/>

HelloGoogleMaps.java

package com.example.googlemap;
import android.app.Activity;
import android.os.Bundle;
import com.google.android.maps.MapView;
import com.google.android.maps.MapActivity;

public class HelloGoogleMaps extends MapActivity 
{
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main);
}

@Override 
protected boolean isRouteDisplayed() { 
    return false; 
}

}

HelloGoogleMaps Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.example.googlemap"

  android:versionCode="1"
  android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">

<uses-library android:name="com.google.android.maps" />

    <activity android:name=".HelloGoogleMaps" android:label="@string/app_name">

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

</application>

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> 

 </manifest> 

Any thoughts??

Thanks!
