Android: Setting Zoom Level in Google Maps to include all Marker points

I am trying to set zoom level for Maps in android such that it includes all the points in my list. I am using following code.

int minLatitude = Integer.MAX_VALUE;

int maxLatitude = Integer.MIN_VALUE;

int minLongitude = Integer.MAX_VALUE;

int maxLongitude = Integer.MIN_VALUE;



// Find the boundaries of the item set

for (GeoPoint item : items) { //item Contain list of Geopints

int lat = item.getLatitudeE6();

int lon = item.getLongitudeE6();



maxLatitude = Math.max(lat, maxLatitude);

minLatitude = Math.min(lat, minLatitude);

maxLongitude = Math.max(lon, maxLongitude);

minLongitude = Math.min(lon, minLongitude);

 }

 objMapController.zoomToSpan(Math.abs(maxLatitude - minLatitude), Math.abs(maxLongitude - minLongitude));

this works sometimes. However sometimes some points are not shown and I need to then Zoom Out to view those points. Is there any way to solve this problem?
