Media Section: Files Quantity

[Romulo_Marquez]

Hi there,

Does anyone have an idea how many images I can upload in the media section?

Each image weighs around 20 kB.

Thank you!

In theory, using the ai2 server, you could have @ 1300 20kB images in your assets, given you do not have any other assets. A compiled app on the AI2 server cannot be larger than 30mb, and the build process introduces an overhead of @ 3.5mb.

In practice, too much of anything can break AI2. That said I have seen projects with 100s of small asset files which work well.

It might be better/easier to download these images to your app on first run, either all at once, or as required, keeps your initial app light...

Hi TIMAI2,

Thank you for your feedback!

mmmmm I'm not expert but... sound very interesting your comment regarding download the images in the first run... Because maybe is an easy solution to my problem.

Do you have any idea how I can do something like what you propose?

Best regards
RM

App size limit help

http://ai2.appinventor.mit.edu/ AIA size: 30 MB number of screens should be < 10 http://code.appinventor.mit.edu/ AIA size: 50 MB number of screens should be < 10 The APK size also depends on the files types (incompressible / compressible) in the assets. See also here:

How many images does your App require Romulo? You can start by optimising them:

Dimensions as small as is practical, 24 bit instead of 32 bit if there is no transparency required, webp format instead of png. webp is as good as png but much lighter. For example I have a button icon 32 bit image that is 12.00 KB in png format but only 2.00 KB in webp format.

iOS build server updated to 2.64.6 (2)

Google still enforces an upper limit of 32 MB for most incoming and outgoing payloads. My guess is that the final IPA ends up being too large for the build server to return to the App Inventor server running in Google App Engine between the compiled app bundle plus all of the assets. I will have to experiment to see if that's the root cause.

Yes, that could be true, this IPA with 162 files was compiled. [grafik]

how many images I can upload in the media section?

On the main server https://ai2.appinventor.mit.edu/ ~150–300 depending on the file sizes. On the code server https://code.appinventor.mit.edu/ more than 1000.

Yes. You can drag and drop them. It is a slow process (not the dragging, but AI's processing). Sometimes some files don't go into the Media correctly and you have to redo those particular files. Alternatively you can us an unzip tool to explode the aia and enter the html files by adding them there). Yes. I have an app that uses about 1000 html files that are text only. The size limit is 5mb; I don't know what the number of files limit is but 1000 works for me ; 150 should not be a probl…

Hi ChrisWard,

Analyzing, my app will storage around 650 images of 20 kB each. So, with only images the app will be close to the 13 MB...

I will study the option from TIMAI2, just in case the app get struggle to work...

Thanks.

As I said, this is not possible on the main server. Read my posts...

Actually the easiest way:

1. Batch convert the png files to webp: https://www.irfanview.com/ (free)
2. Use SteveJG's method to add them to the App Assets 'through the back door' and develop the App on the Code Server. Assets app - limit - #9 by SteveJG (previously posted by Anke)
