Bert Just did a quick and dirty test and got our locking orientation code: AppMobi.device.setRotateOrientation("landscape"); working. Just search your index.html code and paste it in the top of the "appMobi.device.ready" event listener function.
We also have orientation setup when you build the app through our build system.
I recommend trying your game on device by using our "appLab" test container (can be found in both the App Store and Market), since our XDK emulation doesn't always display the C2 output correctly.
You can find the appMobi API commands here: appmobi.com/documentation/jsAPI.html
Just make sure the event "appMobi.device.ready" has fired before making any calls since the appMobi.js lib has to be loaded
Any help with this would be greatly appreciated. It's like Chinese to me. Maybe just an example html with the orientation locked?
