it doesn't show me map on emulator

[sameera liyanage]

here is GMapsActivity java class

package com.android.mymap;


import java.util.List;

import android.graphics.drawable.Drawable;
import android.os.Bundle;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import com.google.android.maps.Overlay;
import com.google.android.maps.OverlayItem;

public class GMapsActivity extends MapActivity {

	private MapView mapView;
	private static final int latitudeE6 = 11985339;
	private static final int longitudeE6 = 23716735;

	@Override
	public void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		mapView = (MapView) findViewById(R.id.map_view);
		mapView.setBuiltInZoomControls(true);

		List<Overlay> mapOverlays = mapView.getOverlays();
		Drawable drawable = this.getResources().getDrawable(R.drawable.icon);
		CustomItemizedOverlay itemizedOverlay = new CustomItemizedOverlay(
				drawable, this);
		GeoPoint point = new GeoPoint(latitudeE6, longitudeE6);
		OverlayItem overlayitem = new OverlayItem(point, "Hello",
				"I'm in Athens, Greece!");

		itemizedOverlay.addOverlay(overlayitem);
		mapOverlays.add(itemizedOverlay);
		MapController mapController = mapView.getController();
		mapController.animateTo(point);
		mapController.setZoom(6);

	}

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

}

this is CustomItemizedOverlay java class

package com.android.mymap;

import java.util.ArrayList;
import android.app.AlertDialog;
import android.content.Context;
import android.graphics.drawable.Drawable;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;

public class CustomItemizedOverlay extends ItemizedOverlay<OverlayItem> {
private ArrayList<OverlayItem> mapOverlays = new ArrayList<OverlayItem>();
private Context context;
public CustomItemizedOverlay(Drawable defaultMarker) {
        super(boundCenterBottom(defaultMarker));
   }
   public CustomItemizedOverlay(Drawable defaultMarker, Context context) {

        this(defaultMarker);

        this.context = context;
   }
   @Override

   protected OverlayItem createItem(int i) {

	   return mapOverlays.get(i);
   }
   @Override

   public int size() {

      return mapOverlays.size();
   }

   @Override

   protected boolean onTap(int index) {

      OverlayItem item = mapOverlays.get(index);

      AlertDialog.Builder dialog = new AlertDialog.Builder(context);

      dialog.setTitle(item.getTitle());

      dialog.setMessage(item.getSnippet());

      dialog.show();

      return true;

   }

   public void addOverlay(OverlayItem overlay) {

      mapOverlays.add(overlay);

       this.populate();

   }

}

this is my manifest file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.android.mymap"
      android:versionCode="1"
      android:versionName="1.0">
<uses-permission android:name="android.permission.INTERNET"></uses-permission>


    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".GMapsActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
 <uses-library android:name="com.google.android.maps" />


    </application>
</manifest>

The problem is with the map key and .keystore file. Your are using wrong key to display map.

This tutorial has method to create key with the debug.keystore file.

Follow the steps carefull and you will have your map loaded
