Android GPS map shows grid

Issue

After 30 hours of programming and failing at this, I realised I couldn't do what I wanted. So this is a last ditch effort to score a pass.

Trying to implement google api to show stuff on a map.

I've basically followed the Android tutorial entirely and it still refuses to work.

It just shows the grid on the MapView, my friend tested my api key so it should be fine.

The only permission I was supposed to use is

android.permission.INTERNET

I've seen the other thread, but I'm positive the key is fine and I think the permission is in the right place.

 <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="key"
   />


 </LinearLayout>

manifest

<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.INTERNET" />
<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" android:debuggable="false">
    <uses-library android:name="com.google.android.maps" />
    <activity   

import java.util.List;

 import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import com.google.android.maps.Overlay;
import com.google.android.maps.OverlayItem;


import android.graphics.drawable.Drawable;
import android.os.Bundle;

public class Main extends MapActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

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

    List<Overlay> mapOverlays = mapView.getOverlays();
    Drawable drawable = this.getResources().getDrawable(R.drawable.androidmarker);
    MyItemizedOverlay itemizedoverlay = new MyItemizedOverlay(drawable);

    GeoPoint point = new GeoPoint(19240000,-99120000);
    OverlayItem overlayitem = new OverlayItem(point, "Hola, Mundo!", "I'm in Mexico City!");

    itemizedoverlay.addOverlay(overlayitem);
    mapOverlays.add(itemizedoverlay);
 }



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

seems I was premature, I built another key, exactly as I did last time. This time the key worked.

but now the problem is, when I click on zoom, it force closes teh application

Solution

dont use debug.keystore. Use new keystore. Right click on ur project>Android tools> Export signed application package. Create new keystore (Remember alias name and password).

Now use following command in command prompt:

cd "C:\Program Files\Java\jdk1.7.0_01\bin


keytool -v -list -alias <ur alias name> -keystore <ur keystore name>.keystore -storepass android -keypass android

It asks for password later it gives a MD5 fingerprint Use that md5 fingerprint to generate google api key. Replace the key. Now Project Right Click>Android tools>Export Signed Application package>

Use existing keystore

select previous keystore and u get apk in release mode. check installing this apk.It should run properly.
