About .aia files

[Aous Karoui]

Hi AppInventor Community,

I wanted to check the .aia files' content so I have unzipped them to look inside. However, when I zipped them again (with both winrar and winzip) in order to import them to AI2, it doesn't work. AI2 tells me that "The selected project is not a project source file! Project source files are aia files". This probably means there is a problem with the .aia file. Is there a special process to recreate the right .aia format ?

Thank you for your help,

Cheers

Hi Aous,

make sure you select the files needed and then zip them, instead of
zipping the folder those files are contained.

When the projects is uploaded, the system will look for the files, but
it if finds a folder, it won't know how to deal with it. Does that
make sense?

cheers,
José

I have read reports that 7-zip puts them back together better.

On a Mac, the following works if you're connected to the directory holding the assets and src files: 

[~/test/DriftingThroughWellesleyTest]$ ls

assets                  src                     youngandroidproject

[~/test/DriftingThroughWellesleyTest]$ zip -r ../DriftingThroughWellesleyTest.aia assets src youngandroidproject

The resulting .aia file loads fine in App Inventor. 

The following transcript shows what the contents of the .aia file should look like. 

[~/test/DriftingThroughWellesleyTest]$ cd ..

[~/test]$ ls -al DriftingThroughWellesley.aia

I'm currently trying to zip them again with 7zip. However, there are too many options that can be specified before zipping. Could you please send me the report that's explaining that ? (or tell me where did you found it). I think when the right zipping options are selected, it may be work!

Hi José,

When you said "the files needed", de you meant ".bky" and ".scm" files ? I tried to zip them and import them directly in AppInventor2, I got the same error message. I gathered also all the files that I found and zipped them directly to one file, then  I changed its extension to ".aia", but I got the same error message (bad format).

Do you know the files that the system will exactly look for ? Does their organization in the different sub-folders (e.g. "src", "assets" and "youngandroidproject") matters ?

Okay, it doesn't seems to be difficult on Mac. I'm using Windows unfortunately but I will look for Mac computer to try that. I think the commands are the same for Linux, so I will check it with that too. Thank you for your help !

As far as I know, you want to zip (the recursive contents of) the three folders named "assets", "src", and "youngandroidproject", so that the contents of the .aia files looks like this: 

[Aous Karoui]

It finally worked ! I just had to edit the files directly on the 7zip browser then they've been saved automatically in the ".aia" format.

Thank you for your help.
