App Inventor Continues Life at MIT

An anonymous reader writes with a press release on the App Inventor Weblog. From the release: "MIT announced the launch of the new Center for Mobile Learning, with a first activity being to take over and refine App Inventor for Android. The center will be led by App Inventor mastermind Hal Abelson, Mitch Resnick of Lego Mindstorms and Scratch fame, and Eric Klopfer, the director of teacher education at MIT and an expert in games and simulation. This news boomerangs the negativity surrounding Google's discontinuation announcement last week. To the many teachers whose curriculums have been energized by App inventor, and to the thousands of newly empowered app builders: Rejoice! The fun has just begun!" Personally I see this as a great thing. By axing App Inventor as a Google Project and releasing the source there is finally a real world example of using Scheme to write Android applications that others can inspect.

    I used to teach a Lego Mindstorm based after-school program. If this guy can make a GUI on top of LabView that is easy enough for 4rth graders to master, I can't wait to see what he does with the Android SDK/ App Inventor.

      It would be nice to see.

      As long as such a GUI selectively reveals to the user, what the logic of programming is actually like.

    "... there is finally a real world example of using Scheme to write Android applications that others can inspect." You mean as long as there aren't any 10-deep or more nested expressions in the code or you've messed around with .emacs files a lot. Otherwise, Scheme becomes rather un-inspectable. I'm having some disturbing flashbacks from my undergrad days as I write this.

    Didn't the "discontinuation" announcement specifically say that they were simply stopping it being a Google branded thing and open sourcing it? Not only that, but they also said they had plans to continue developing it. They were just killing the Google branded part. It was never going away in the first place.

      It's news because the original story detailing that Google would not be supporting this software once again gave the shills and google haters something to crow about. google is abandoning teachers, google is abandoning disadvantaged people, and women, ad nauseum. I don't feel like dragging up the link to the original Slashdot story about this but it was some professor somewhere who literally said those things. It was ridiculous. And of course everyone with an axe to grind chimed in. I think in the face of that, a positive followup story is well appreciated.

      As opposed to the mechanic who knows how to fix Chevys up to the 1979 model year and feels like he doesn't need to upgrade his skills, or the COBOL programmer? Or the doctor that raises leeches for draining your foul humors. (Or, for that matter, Dr. Bob, our resident chiropractor?)

      The STEP program was actually responsible for developing the graphical programming system (OpenBlocks) used by App Inventor. OpenBlocks was originally invented for use in the StarLogo TNG environment, but was deliberately designed to be general and suitable for other block based visual programming languages.

    At least this exercise taught us one thing: The wrong way to transition a product to open source.

    1. Re:Scheme on the Android by Unknown+Lamer · · Score: 1

      Moby is a limited educational environment that does not expose the full Scheme language and integrates poorly with the rest of the environment (you can't e.g. call Java protocols directly from Scheme... which could be problematic). Kawa, OTOH, compiles to Java bytecode that can be transformed into DEX just like any normal Java. Since it compiles to Java you can directly call of the Android protocols making it actually useful. The only problem is that getting it into the build chain is a bit mystifying at least for this Schemer (ant is not really what I would consider intuitive). Java protocols also tend to not fit very cleanly into traditional Scheme program structure.

      My hope is that the App Inventor source will have good examples of using the Android protocols in a Schemey style and especially how to sanely build programs with the Kawa library.
