Android: Google Maps not displaying

I'm trying to get a google map to display. I can see the background (light gray background, small tiles, Google logo in the lower left), so I know that I'm close. However, there is no actual map displayed. In the LogCat, I see this message repeating over and over:

05-14 13:28:17.926: W/System.err(27458): at android_maps_conflict_avoidance.com.google.googlenav.datarequest.DataRequestDispatcher$DispatcherServer.run(DataRequestDispatcher.java:1702)

I'm using Google maps api 2 with a tethered phone for testing that is running 2.3.4.

Anyone know what might be causing this? Thanks!

package com.example.maptest;
import android.os.Bundle;
import com.google.android.maps.MapActivity; 
import com.google.android.maps.MapController; 
import com.google.android.maps.MapView;

public class MyMapActivity extends MapActivity {   

  private MapView mapView;   
  private MapController mapController;

   @Override   public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.map_layout);
     mapView = (MapView)findViewById(R.id.map_view);
   }

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

 }

This problem is usually related to the map API key used to sign manifest. Take a look at this post and this one which describe the same error you are experiencing. In both cases it is because the API key they used was created with the wrong keystore. You need to make sure you use your debug keystore when you create an API key in the Google API console if you are going to be testing from eclipse.
