Google Maps API v2: LatLngBounds from CameraPosition

You can’t get the LatLngBounds from the CameraPosition, but you can get them easily from the GoogleMap.

private GoogleMap mMap;

mMap.setOnCameraChangeListener(new OnCameraChangeListener() {
            @Override
            public void onCameraChange(CameraPosition position) {
                LatLngBounds bounds = mMap.getProjection().getVisibleRegion().latLngBounds;
                fetchData(bounds);
            }
        });
