The OpenStreetMap London hack weekend also saw Jo Walsh working on the first stage of a building details editor for Android.
Jo, who goes by the OSM user name zool, has written up her experience of working with Android:
I worked on a mobile app which I was pleased to get into a basically working state. It is called osmbi3, which stands for OpenStreetMap Building Information and/or Zombies. The aim was to geolocate the user and find nearby buildings using an Overpass query. This could then be linked to building management information or form the basis for some location-based game.
