Friends,
in the following application----------
package mycom.ju.gmap;
//import HelloItemizedOverlay;
import mycom.ju.gmap.R;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.widget.*;
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 java.util.ArrayList;
import java.util.List;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
public class gmap extends MapActivity {
//Called when the activity is first created.
MapView mapView;
Toast toast;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try{
mapView = (MapView)findViewById(R.id.mapv);
mapView.setBuiltInZoomControls(true);
mapView.displayZoomControls(true);
mapView.setTraffic(true);
}
catch(Exception e){ toast = Toast.makeText(this,e.toString(),
Toast.LENGTH_LONG);
toast.show();
}
setContentView(R.layout.main);
}
@Override

return true;
}
}
-------main.xml-----------------------
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:id="@+id/mainlayout"

</LinearLayout>
The map is showing perfectly but but not in traffic view , neither the
zooming button is visible . I used the try -- catch just to check
where the problem is . When ever I'm using mapv object to call any
method of MapView class it's giving Null Pointer Exception . I even
tried other constructor of MapView class like
MapView( this, "02OwWVKUsUMSUwUZPEOHkWSQge2bW6FOISMYvDw") ;
I even checked whether mapv contains null or not [ using mapv.equals
(null)] . But it's not null either.
But problem remains the same . Please helppppp .
