Determining suitable zoom level based on a set of locations for OSMDroid

Question

From Google Maps Android API v2, I understand that this can be done through this method:

LatLngBounds.Builder builder = new LatLngBounds.Builder();
for (Location loc : allLocations) {
    LatLng position = new LatLng(loc.getLatitude(), loc.getLongitude());
    builder.include(position);
}

CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(builder.build(), someMarginValue);
map.moveCamera(cu);

However I can't seem to find a way to do this for OSMDroid. Is there a solution/ class to help determine the zoom level based on a set of locations?

I need the zoom level to be determined first as I am downloading a specific set of maptiles for offline display. However to do that I need to determine the right zoom level to download from the server first... Are there any algorithms out there that can determine this zoom level first?
