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?

Maybe the OSM wiki can help about Zoomlevels
