How do I lock device to one landscape only ?

I'm using landscape option and it works. But it turns to other landscape if I tilt device to other side and wait. In my game player moves with tilting.

I added browser object and

on start of layout -> lock oriantation to primary landscape

But it didn't effect anything, it still turns to other lanscape.

I'm using crosswalk.

It seems, its very difficult to make such an easy tilting game to android with c2 or I suck

Here is my other problem about my game

Unfortunately there is no way to lock the orientation of a mobile web browsers unless they support it. You have to add a "Rotate Device" solution.
