Too many files in Assets?

[Paolo Ballarini]

Hi, 

I have a project created with App Inventor that contains many small JPG files in the Assets. (about 400, by 3 kbytes each)

I have problems loading the project into the builder....

My AIA project is large 1.36 MBytes

Do you know if there is a physical limit in the number of possible files in the Assets folder?

Thanks to everyone

Quite possible

Try a routine to import all these files on first run of the app.

See here

Although there could be another issue with your app causing the problem - check for "empty blocks" for example

Thank you Tim,

I have exported the fully functioning AIA project to my PC with no media in the assets folder.

Then I manually inserted my files in Assets folder (I did it again.... but with fewer files...)

I used WinRar to edit the AIA file.

Then when I reload my project onto the server.... here is the error.....

PS. I can't upload files in runtime, my app must work off-line

From my PC I have edited the AIA file (with WINRAR), I have removed almost all the files from the Assets.... folder.

Now the builder loads my project....

I think there is some limitation (server side) for the amount of files....

If your app must work offline, how are users getting the app?

If directly from you or via email then you could provide a zip file of all your images, with the app coded to a specific directory that they need to install to

If from Play Store/via email/other download, then they will be online, so they could do file by file?

Suggest keep testing until you find the limit (by adding say 50 images at a time, until it no longer compiles)

I am not aware of a precise number of files limit, but this does seem to be the problem.

Have you tried building using

code.appinventor.mit.edu

?

It uses a different back end.

Hi friends,

Yes, I have tried "http://code.appinventor.mit.edu/" and it works well, always upload my project, without problems!

I also tried the off-line version of App Inventor, which also always loads my project with many Assets.

I believe that I will resolve this with one of these two solutions.

One last question for Abraham: what does it mean:"It uses a different back end". I'm not an expert, what is back end?

Thanks to everyone

what does it mean:"It uses a different back end". I'm not an expert, what is back end?

As opposed to the front end, which you see,

mostly web servers and Javascript,

a back end runs the parts you can't see, like disk storage.
