How to hide Android Softkeys Navigation Bars?

Has anyone been able to achieve this? On devices like the Galaxy Nexus there are no physical buttons, but onscreen buttons which can't seem to be easily hidden using Unity.

Is there a simple way to hide them?

Thanks.

 

Calling something like this with Java plugin should hide them (doesn't work on honeycomb if I remember correctly, and in Unity 4 it reverted itself back to 'low profile'-mode in a quick test...)

Code (csharp):

1.        View bView = your-activity-here.getWindow().getDecorView();
2.        bView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

Or this if you want to only fade them to dots (works also on honeycomb, and Unity 4 does this automatically)

Code (csharp):

1.        View bView = your-activity-here.getWindow().getDecorView();
2.        bView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
