Is there no simple way to get a device heading in Android with Unity?

Hi,

All I need is to find out how to get the direction the Android device is pointing in, for an AR app our company is looking to develop.

I will also need to access the device camera as a background to the 3d game-world, but right now I'm just starting out.

I can access the GPS of the device, so in the 3d world of the app, I place an object at certain x/z co-ordinates (multiplied by 1000 - so 35.566754 degrees latitude in real life would be 'x' co-ordinate 35566.754 in the app 3d world), and while I can sucessfully match the 3d-world camera to the real life device position, I cannot seem to match the camera to the device direction - the camera must always look at the target object - not ideal for AR purposes.

We're just prototyping at the minute, and haven't settled on a development environment yet, but we did notice Shiva can access Android compass headings quite easily with one line, see here: http://www.stonetrip.com/developer/doc/api/system-getLastKnownHeading

So if it's that simple to get the compass bearing in Shiva, why can't Unity?

The only kind of answer to this question I've seen on Unity Answers links to here: http://answers.unity3d.com/questions/43794/compass-java-plugin-for-unity-android.html

Which doesn't really help us, as the answer is psuedocode, and a bit complex for what should be a simple task of accessing a vector heading from a part of the android device.

Can anyone shed some light on a possible solution for this, or is Shiva superior for this kind of thing?

Any help appreciated.
