Can anyone help me get this map app working?

Question

The problem is that my map isn't showing. It's just the grid that shows when you (for example:) haven't got the INTERNET permission.

Here's my java class:

public class MapClass extends MapActivity {

 public void onCreate(Bundle icicle) {
  super.onCreate(icicle);
  setContentView(R.layout.maplayout);

  MapView mapView = (MapView) findViewById(R.id.mapView);
  mapView.setBuiltInZoomControls(true);
    }

 @Override
 protected boolean isRouteDisplayed() {
  // TODO Auto-generated method stub
  return false;
 }
}

Here's my XML Layout file (minus the Map Key):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/mainlayout" android:orientation="vertical"
 android:layout_width="fill_parent" android:layout_height="fill_parent">

 <com.google.android.maps.MapView
  android:id="@+id/mapView" android:layout_width="fill_parent"
  android:enabled="true" android:layout_height="fill_parent"
  android:clickable="true" android:apiKey="MY-API-KEY" />

</RelativeLayout>

And here's my Manifest File:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="com.android.mapexample" android:versionCode="1"
 android:versionName="1.0" android:installLocation="internalOnly">

 <application android:icon="@drawable/icon" android:label="@string/app_name"
  android:debuggable="true">

  <uses-library android:name="com.google.android.maps" />
  <activity android:name=".MapClass" android:label="@string/app_name"
   android:theme="@android:style/Theme.NoTitleBar">

   <intent-filter>

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

   </intent-filter>>

  </activity>
 </application>

 <uses-sdk android:minSdkVersion="1" />

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

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

</manifest>

Make sure your app is signed with the signing key you associated with your Map API key. I suspect you are debugging, so the app is signed with the debug keystore...you have to generate a different Map API key for that.

I keep 2 layouts, one for each Map API key. I dynamically choose my layout based on whether I am running in a debug or release build.
