Record picture orientation

[GoogleCodeExporter]

Most (if not all) Android devices have an compass built in.

The idea is to record image orientation and to display it later in the JOSM
editor.

Thanks for your feedback.

The idea is interesting, however it means developing a small camera application
instead of using the Android built-in. This requires an bit of works, however it
could solve other problems with pictures (see issue #11 and issue #3).

Could this be accomplished without coding a separate camera app by recording 
the phone 
orientation in the background while the camera is open and then using the time 
stamp 
of the picture to figure out what was actually used? That might be a 
dangerously messy 
hack, I don't know.

But this feature would be useful.

Seems to be a messy hack ;) but it's an interesting workaround to the camera-app
coding problem.

As there is background service that records location, it can be alerted that a
picture will be taken, and start recording compass data until it gets the 
picture.

The orientation data could be recorded in the picture EXIF data (seems to be a
"GPSImgDirection" field for that), or in the GPX file using a specific 
extension.
Record it in EXIF means re-open the file, update EXIF, and closes it, as the 
file is
first saved by the built-in camera app.

Sounds good to me :)

I'm also looking for a way to exploit the whole potential of the Android 
built-in camera and thereafter add GPSImgDirection in Exif. This sound like an 
excellent idea to me :)
