Indeed, 0 is the identity value for the + operator, and 1 is the identity value for the multiplication operator.
(There is probably a math term other than "Identity value', but I can't remember it.)

P.S. Change those > to ==> so they don't look like GREATER THAN operators.

While I agree with the technicalities here, I don't think it's really all that helpful in a language that's aiming to be approachable to non-programmers. For example, can you tell me which blocks these are?

My reasoning for preventing being able to reduce the number of inputs below two is to prevent these types of ambiguities. I've added this to our agenda for our staff meeting today (we can always relax the restriction at a later time).

I personally found the discovery that I could remove inputs to math operations a pleasant surprise, like the discovery of zero across domains.
It tickled my math funny bone.

Why deprive students of that fun?

(Further thoughts, probably too late for your staff meeting ...)

Breaking things is a great way to learn.:

  • Breaking atoms
  • Breaking atomic nucleii
  • Breaking protons
  • Breaking speed limits, sound and light
  • Breaking the bounds between light and matter

I vote for breakable.

What about the background image resolution scailing? was that sorted lately?

    • Add support for services and content providers in extensions (thanks @shreyash)
  • Bug fixes:
    • Prevent deactivate gallery URLs from opening

Great! I actually couldn't delete my app because of this problem... Good thing it's fixed!

Hi,
May I know from when nb184 is going to be live ? We are almost nearing august. In the "About App Inventor" it still shows nb183c.

"By August 3, 2020, new apps must target at least Android 10 (API level 29). By November 2, 2020, all apps that are being updated must target at least Android 10 (API level 29)."

I've tried the testing environment. I am not sure if I can build an APK and upload it to PlayStore from the mentioned test link. However I tried it and got the following error.

APK Upload Error
APK Upload Error1274×464 65 KB

What I inferred is that the app should be built after nb184 will be live. Please correct me if I am wrong.

Take the hint, your app has overstayed its welcome and must escape to safety.

Export the .aia file from the test server, and reload it into the production server.

If you did not add new component types, you should be okay to build from the production server.

We are planning for the release to go live Thursday night US Eastern time.

Export the keystore from http://ai2.appinventor.mit.edu/ and import it into ai2-test server and try again.

It worked. Thank you :slight_smile:

I found this little bug:

It only happens when switching to external inputs.

Thanks for the report, @Italo.

Edit: A fix has been reviewed and will be in the bugfix release:

Revoke the new relaease now and only provide it if its running without corrupting previously written APKs.
Never change a running timer and above all don't bring it fall with nice to haves.
