android Get the azimuth of phone when picture was taken

Question

I can use the SensorManager and SensorEventListener to get the azimuth. I am wondering if the built in Intent to capture an image provides the azimuth or orientation? Thanks Jon

Not by default... but good idea.

Here's a list of exif tags present on one of the pics from my Moto droid on Android 2.1.

I bet there's a way to add it to the image... With the onboard orientation sensor you can calculate azimuth.
