If you built it for Crosswalk, did you make sure you changed the tab of build settings to 'Android (crosswalk)' and didn't accidentally set things up for normal Android build? That tab is open by default and I sometimes accidentally set things up there.
If you still can't get it to work, you should probably ask about it at the XDK forums as well:
Yeah, performance is a lot better disabling standard Android and just using Crosswalk, but no luck fixing it to portrait even when the phone is on it's side. The emulator also doesn't lock the orientation :/
