Here's a good way using resources and size qualifiers.

Put this bool resource in res/values as bools.xml or whatever (file names don't matter here):

    xml version="1.0" encoding="utf-8"?>   name="portrait_only">true 

Put this one in res/values-sw600dp and res/values-xlarge:

    xml version="1.0" encoding="utf-8"?>   name="portrait_only">false 

Then, in the onCreate method of your Activities you can do this:

    if(getResources().getBoolean(R.bool.portrait_only)){ setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); }

Devices that are more than 600 dp in the smallest width direction, or x-large on pre-Android 3.2 devices (tablets, basically) will behave like normal, based on sensor and user-locked rotation, etc. Everything else (phones, pretty much) will be portrait only.
