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"?>
<resources>
<bool name="portrait_only">true</bool>
</resources>
Put this one in res/values-sw600dp and res/values-xlarge:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<bool name="portrait_only">false</bool>
</resources>
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.
