Setting view on mapview based on gps coordinates

I'm trying to set the bounds on the mapview that I'm working with, so I'm always centered a certain way, and I can also see a full set of information based on the view. Basically I'll get a GPS coordinate for the center point, and then I'll get another value, say .9, which is the difference in the x/y of the current GPS spot that needs to be present in the current view. Example

Center-point: 37.777125, -12.2419644 (San Francisco)

Difference: .9

So the view would need to be 

Top-Left: 36.877125, -13.1419644
Bottom-Right: 38.677125, -11.3419644

Is there a way to set the map view's bounds in this way?

It is. There is an interface in mapView's controller - zoomToSpan(long, long). What you need is to do the following:

long latSpan = Math.abs(startLat - endLat);
long lonSpan =  Math.abs(startLon - endLon);

mapView.getController().zoomToSpan(latSpan, lonSpan);

Where startLat, endLat, startLon, endLon - your calculated boundaries
