Android Google Api "failed To Load Map"

I'm trying to display Google Map's map. I followed this tutorial. I Fixed some problems and the application runs, but I could not display the map. Here what I did: Created an API

Solution 1:

Inside your application tag (in manifest) add:

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

Replace your fragment XML by this:

<fragment
      android:id="@+id/map"
      android:layout_width="match_parent"
      android:layout_height="match_parent"class="com.google.android.gms.maps.SupportMapFragment"
    />

Let your activity extend FragmentActivity and onCreate and onResume call this code:

intstatus= GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

if(status == ConnectionResult.SUCCESS){
   if (mMap == null) {

      mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

      if (mMap != null) {
        UiSettingssettings= mMap.getUiSettings();

        settings.setZoomControlsEnabled(true);
        settings.setCompassEnabled(true);
        settings.setRotateGesturesEnabled(true);
        settings.setTiltGesturesEnabled(true);
        settings.setScrollGesturesEnabled(true);
        settings.setZoomControlsEnabled(true);
        settings.setZoomGesturesEnabled(true);
        settings.setMyLocationButtonEnabled(false);

        mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        mMap.setMyLocationEnabled(false);
      }
    }
}

Don't forget to declare your mMap variable like this:

private GoogleMap mMap;

Solution 2:

Based on nsvir's earlier edit generating a new debug.keystore and a new key solves this problem.
