  • App Inventor Incompatibility Crisis

    We have downloaded the new versions of driver's station app and App Inventor but when we download the file for our app we created, and put it on the phone, and try to connect the driver's station with our app, it says the app we created is still in V1 while the driver's station app is in v4. We fully understand how to achieve the different versions of the driver's station, but cannot seem to get the proper version of app inventor. We have been working on this for three days.

    Hi 9955,

    We've had issues updating to the newer versions of the AI "appliance" for VBox. Here's a copy-past from another thread: http://ftcforum.usfirst.org/showthre...ll=1#post26849

    This has worked well for us.
    I've yet to figure out how to determine what build is installed in VirtualBox. When in doubt, I just go to http://http://frc-events.usfirst.org...ages/2016/beta and replace. I had problems with the replacing "LocalAppInventor", but found that this works:

    1. Backup all your App Inventor files with: Projects --> Export all projects
    2. Remove LocalAppInventor appliance (hover over and right click for menu)
    3. From menu, select "Remove all files". The new appliance wouldn't install if I clicked "Remove only". I'd have to uninstall VirtualBox, find and delete all directories and then re-install VirtualBox.
    4. Unzip the projects to a Windows directory. It's a good practice to do this routinely anyway...
    5. Restore your projects by: Project --> Import project (.aia) from my computer. You have to import each project.


    I've never had a problem using the above. There may be a way to keep the AppInventor files and update the LocalAppInventor appliance, but I haven't found it.

      Here's how to tell what version of App Inventor you are running.

      In App Inventor, in the designer, click on Screen1 and the look at the VersionCode and VersionName properties.
      For the February 2016 Beta release, VersionCode should be 7 and VersionName should be 1.6.
      For the January 2016 release, VersionCode should be 6 and VersionName should be 1.5.
      For the November 2015 release, VersionCode should be 5 and VersionName should be 1.25.

        Just tested on my 4th computer, I was able to avoid step #3 with "Uninstall, Reinstall VirtualBox" by going into the VirtualBox menu and deleting the LocalAppInventor files in the "Machine" "Add" menus (then delete the files there).

        Saves a lot of time! So far everything seems to work now.
