how to set default screen orientation landscape in android app

Question

I want to have portrait screen orientation in mobile view and both orientations in tablet view I didn't define orientation in manifest but I check if the device is not tablet make orientation portrait in code by this line:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

this code works in tablets perfectly but the problem occur when I try to run the app in landscape on tablets, first app runs in landscape and then change to portrait by code. so onCreate function run twice. I don't want to do this twice!

for example may I define a variable in values-sw600dp for example and use it to change orientation in manifest? or change manifest orientation priority?! (and set orientation in code?!)

yes if is mobile only portrait orientation and if is tblet both orientation! — h.kelidari, Oct 13 '13 at 14:21

A work around that I had used, is to supply a main layout for tablets, and i add an invisible view "dummy_for_tablet" and from main activity

    @Override
    protected void onCreate(Bundle savedInstanceState)
    { 
         ....
         if( findViewById(R.id.dummy_for_tablet) != null)
         { //it's a tablet }
         else
         { //it's a mobile }
          ...
    }
