A bug was found. An embarassing one, but now it’s fixed and a new update is available on market!
The bug caused the history log-files not to be saved, which made the applications main-task to fail, but the fix was easy and now it’s working again. The reason was that the application tries to access the memory card to verify that it’s available and writable before starting a log (so you don’t log for 5 hours and then not possible to store the coordinates), but it created a file with the same name as the directory it tries to save the log-files to later, which made the directory creation to fail. A file and a directory with the same name cannot exist in the filesystem.
Many excuses to the affected people (probably <5 people since the application is new 
)
Battery statistics
I’ve been testing the application with 5seconds interval on a fully charged HTC Hero running Android 1.5. The results were pretty impressive, allthough I was running without a SIM-card and with wifi off (like airplane mode). It ran for about 12 hours, and then I turned it off manually, but it will run for an estimated 15 hours @ 5sec interval before battery is fully drained.
