Looks like we're in for some more snow days, so maybe a good reason to use your extra time at home inventing in Scratch 2.0 and App Inventor!

A quick clarification about uploading App Inventor source files into your own App Inventor account. When I told you to look for "aia" files that I'd upload to the class wiki, I was following the MIT instructions for the new App Inventor 2 (AI2) process. However, we created our App Inventor projects using the java "App Inventor Classic" version (AI1). And for this version, your projects I uploaded to the class wiki are "zip" files. Take a look at the MIT instructions for the "App Inventor Classic" (AI1) process. Keep in mind that MIT is taking App Inventor through a major overhaul, trying to transition the entire platform from this "Classic" AI1 version to the new cloud based "AI2" version. And as is often the case with overhauls, there are still some wrinkles. It seems that currently, a "Classic" AI1 project cannot be opened using the AI2 platform. But, MIT is working on making that possible. Take a look here for more details to follow their progress, as well, a link if you'd like to create an App Inventor account using the older "Classic" AI1 platform (if you access App Inventor through the appinventor.org site, it contains instructions for AI2). For example, I have one App Inventor account that I originally created when only AI1 was an option, which now lets me also connect using AI2, but at the time I created the lesson plans for this Saturday Enrichment class, AI2 wasn't ready to allow a PC/Android connection to the emulator/smartphone, which is why I used AI1 to create class projects. The key is staying flexible, ready for the next change in this ever evolving tech world, right?

Sorry for any confusion this caused; you should shortly see a zip file along with your apk file on the class wiki, and I'll follow the latest developments for all things AI to post here when released.
