Hi,

In case anyone might be interested I just thought I'd announce an initial version of "OpenTrail", which aims to become an Android OSM app for walkers and hikers. At the moment it's pretty basic, but I thought I'd announce it now in case anyone's interested in either the project or in contributing code.

OpenTrail, available at http://www.free-map.org.uk/downloads/android/opentrail.apk or via SVN via svn://free-map.org.uk/svn/freemap, currently shows slippy maps from the following sources:
* Freemap
* OS NPE
* OS 7th Edition
* OS First Series
* OSM Cyclemap
using the osmdroid library (same library as is used in AndNav). You can also contribute annotations to Freemap.

What I'm particularly wanting to focus on with OpenTrail is to experiment with augmented reality and try out overlaying OSM data on the feed from the phone's camera, with a view to in the field navigation; thus OpenTrail extends the OpenTrailView idea (hence the similar name). Because my interest in mobile development has now shifted to Android, OpenTrail also replaces a couple of earlier projects I was working on, the Java ME "FreemapMobile" and footnav (OpenGL viewer which was originally aiming to run in a Nokia/Qt environment). 

Only tested on a HTC Hero running Android 2.1 but let me know of any problems.  If you're interested in the project, updates will be posted on the blog http://www.free-map.org.uk/wordpress/.

Nick
