Force tablet to be in landscape mode

Question

Is there a way to force the tablet to be in landscape mode as default orientation when the user start's my app. Is there a way to do this with theming or something like that, so the user doent see orientation change when he is starting the app?

Note: the same app is (should be) in portrait mode for phones

For now I have a boolean values folder refs.xml(both values and values-large) with different value for tablet and phone, but the user can see that the app is rotating Code:

public static boolean isTablet(Context context) {   
        return (context.getResources().getBoolean(R.bool.isTablet));
    }

Answer 1

    if (isTablet(getApplicationContext())) {
          setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    } else {
          setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }
    setContentView(R.layout.yourlayout);



**//this method for check having run in tablet or not??**

     public static boolean isTablet(Context context) {
         return (context.getResources().getConfiguration().screenLayout
                        & Configuration.SCREENLAYOUT_SIZE_MASK)
                        >= Configuration.SCREENLAYOUT_SIZE_LARGE;
     }
