Starting a new class in MIT App Inventor

MIT App Inventor Help

And I'm finding that I need to know it better myself and make sure things are set up well.

  1. So I'm doing the tutorials at http://ai2.appinventor.mit.edu/?locale=en&repo=http://appinventor.mit.edu/yrtoolkit/yr/aiaFiles/hour_of_code/HourOfCode.asc
    When I go to run the app for Touch The Bee it comes up with error 703 both in the emulator and in the Android App.

  2. One of my students is doing a App intro from the Lyra Logan book and it's having permission issues and popping up a SMS permission not allowed. All permissions on the app are enabled.

Welcome Ryan.

Error code 703 means unable to play sound .
This link to Hello Codi might be more useful than the link you provided
Hello Codi!

Have you added the bee sound file to Media?

See
HelloCodi.aia (81.7 KB)

The aia runs fine in an Android 13. :slightly_smiling_face: Yes it buzzes.

Lyra Logan book? Sorry not familiar with that.

A guess is the student is using Companion 2.73a and should be using Companion 2.73u. That will provide the permissions.

Regarding the 703 error,

Export your .aia file and upload it here.

How do I pull that update, the app store isn't seeing it.

Open the AI2 app in your Browser, and find Companion Information in the menu (for the neo interface, this is under Connect)

  • log on to a Project on your desktop Designer
  • select Help
  • select Companion Information
  • from screen that opens scan the QR code with your camera or your present 2.73a Companion on your Android
  • answer Do you want to update the app
  • select update
  • then selet open

Your Companion on your Android should now be 2.73u. Is it? :thinking:

When you next load your project using 2.73u the permissions will probably be there. Test the project; does it work now?

Did not fix my Google 8A - still getting the 703 error after updating and trying that app. But it worked on my students, will keep playing with it.

Possible issues:

  • there is a known issue with the Sound component on some devices. If you see an "OS Error" like 703 and the sound does not play, go back into the Designer and try using a Player component (found under Media) instead of the Sound component.
  • you coded your aia using a video; easy to miscopy something. Check what you coded or load the aia shown in the link I posted and try that. What happens?
  • your Pixel 8a is either an Android 14 or 15; this could be an Android 15 bug?

Google Pixel 8a with Android 15 working fine here using companion 2.73au.
