Preview4 is now available in the same location as previous Preview3/2/1!
As promised, changes in this preview impact the day-to-day use a lot. In my opinion I've fixed the most annoying problems with the previous ones, I hope you think the same. Next version will probably have exporting to video generators, improved analyze views and best of all, it will be available in the Android Market for free!
Changes in Preview4:
 Session can now be resumed (press "Resume" from after opening the session). Every new resume uses completely new files for data storage, so there is no danger of corrupting old data in event of loss of power.
 Added long-press context menu to lap list: Laps can now be marked invalid and comparison lap can be changed.
 Numeric values for X- and Y-axis are now displayed below the Graph
 General usability and performance improvements in the Analyze feature
 User is asked to enable Bluetooth, if it is needed but disabled
 Fixed: "Devices" button was not visible in portrait mode of the Lap Timer
 Fixed: Live Timer showed previous lap as best lap
 Fixed: Crash when last session was deleted and then opened
 Fixed: Automatic track detection from library was broken
 Fixed: Scaled X-axis did not work for comparison lap
Changes in Preview3:
 Implemented browsing the Track Library.
 Implemented submitting tracks to Track Library
 Fixed: Selecting Bluetooth device crashed sometimes
 About track library: The tracks are classified by country, and at the and of the list will have "Unofficial", "Pending review" and "Rejected" -categories. Submitted tracks will appear immediately to "Pending Review" category. You need to press refresh button at the library tab to get the changes. When I modify and make a track official, it will move under country category. If I reject (street racing, ice racing etc.) or make it unofficial (when there is doubt if the track is valid) the track will move to "Rejected" or "Unofficial" category accordingly.
Changes in preview2:
 Fixed: Importing old sessions crashes if only -session.bin file is available (no -plots.bin)
 Fixed: Graph problem with Galaxy Nexus
Comments
 Fixed: Browse tracks list does not download
 Fixed: Importing old sessions crashes
Just curious, do ou have a plan for the next release, this one works flawless but i am very interested in the features. I have said it before but i say again, your work is pretty damn good!
any chance I can download the preview somewhere ? Would save me the hassle of dragging the laptop to the trackdays thanks for your efforts !
Thanks
