Building App with Vertical Alignment on Android

I have something of a basic question involving Unity development for the Droid

I’m doing AR work so my camera input is aligned to whatever way I want it to be when I hold my phone, but the GUI is not aligned the way I want it to be. Currently when I push my project onto the phone, my project comes out horizontally aligned, with (0,0) at the upper left hand corner if the phone is held sideways, y going down and x going to the right. I want to change the orientation such that I can hold the phone vertically and the GUI elements will also be aligned according to a vertical orientation. That is, if I hold my phone vertically (0,0) is on the upper left hand corner (which would be the lower right hand corner if the phone was horizontally held) and y goes down, x goes right. How do I “rotate” my app such that the coordinate system of my GUI does what I want it to do? Currently I’ve tried Edit>Project Settings>Player>Default Orientation but that hasn’t worked, and although in the game view I can get Unity to simulate the proper orientation it doesn’t do it when I build the project to my phone.

This, exactly. I hope we aren’t making the same AR game!

I’m pretty sure it is down to the overridden AndroisManifest.xml, but I haven’t tracked down the line yet.

Adding

android:screenOrientation=“portrait”

To the activity in the AndroidManifest.xml doesn’t resolve my problem, something more sinister is afoot.
