Question

I think this is implementable since screen rotation behaviour can go up to the application level

Wherever possible  please don t use SCREEN ORIENTATION LANDSCAPE or SCREEN ORIENTATION PORTRAIT  Instead use   setRequestedOrientation ActivityInfo SCREEN ORIENTATION SENSOR LANDSCAPE   setRequestedOrientation ActivityInfo SCREEN ORIENTATION SENSOR PORTRAIT     These allow the user to orient the device to either landscape orientation  or either portrait orientation  respectively  If you ve ever had to play a game with a charging cable being driven into your stomach  then you know exactly why having both orientations available is important to the user   Note  For phones  at least several that I ve checked  it only allows the  right side up  portrait mode  however  SENSOR PORTRAIT works properly on tablets   Note  this feature was introduced in API Level 9  so if you must support 8 or lower  not likely at this point   then instead use   setRequestedOrientation Build VERSION SDK INT  lt  9                           ActivityInfo SCREEN ORIENTATION LANDSCAPE                           ActivityInfo SCREEN ORIENTATION SENSOR LANDSCAPE   setRequestedOrientation Build VERSION SDK INT  lt  9                           ActivityInfo SCREEN ORIENTATION PORTRAIT                           ActivityInfo SCREEN ORIENTATION SENSOR PORTRAIT
