Project corrupted after deleting screen – cannot open project

Bugs and Other Issues
1

Hello,

My MIT App Inventor project named "Demo06_SQLite_et_dynamic_components_1_Screen_pointdecontrôle1_Screen_pointdecontrôle1" became inaccessible after deleting a Screen.

The project still appears in “My Projects” but:

  • it cannot be opened
  • buttons like Export / Save a copy stay disabled
  • exporting all projects works, but re-imported projects are also corrupted

Account email: [mod edit - personal info removed]

Could you please restore a previous server backup of this project
or provide a working .aia file?

Thank you very much.

This sounds like the lastscreenopened bug.

Export your affected aia, use this url to avoid opening any projects:

https://ai2.appinventor.mit.edu/?autoload=false

Open up the aia project with a zip program and then open the projectproperties file in the youngandroidproject folder in a text program like notepad.

Change the line lastopened= to

lastopened=Screen1

save the file back into the aia project and try again.

Alternatively, upload your aia project here and someone can do that for you.
