Android - Vertical layout only

Question

How do I make sure my app is only for vertical layout?

I have tried android:screenOrientation=\"portrait\" but that doesn\'t seem to do the trick.

Answer 1

You need to add to all your activity not for one only. I think you understood that setting is per application wide, but it isn't.

Add the declaration to the activity tag in AndroidManifest for every Activity you want to be portrait-only.
