I can't export my project as an APK

[Maz]

Excuse me, I have a question. I can't export my project as an APK, possibly because the media files are too large. Do you have any suggestions for me? [Server error: could not save one or more files. Please try again later!]

possibly because the media files are too large.

To find out, if your assumption is correct, upload the aia file to https://unchive.kodular.io to get some statistics about your project

How to build a big app → APK max. 100 MB or → AAB 150 MB

Note : I added Part 2 on how to build a big app → AAB & sign it to my guide. It takes less than 1 minute to insert large files into the assets and sign the AAB .

Thank you for helping me. Now I’ve uploaded it, what should I do next? I apologize for my limited knowledge, I’m just learning how to write apps.

Is this what you're talking about?

[Maz]

I've encountered another issue. Now, I've deleted media files to keep it under 5MB, but I still can't export the APK.

Try to build the APK on https://code.appinventor.mit.edu/.

The total number of assets or number of blocks might be the issue here... how many blocks do you have on Screen1 and Screen2?

Did you try to build the project on the code server?

Reuse your components, follow the dry principle

Don't repeat yourself

Bug, Mal function or Editor capacity exceeded

When you are stuck in a hole, stop digging. Use a faster web browser like Firefox, on a fast connection, with no overhead. Reduce Blocks Editor load by minimizing all blocks. After minimizing blocks, do a Clean Up Blocks to reduce surface area of workspace. Reduce your block count by changing blocks to data. If your blocks look like a box of combs, you need to generalize. Have a lot of similar events? Use generic blocks.

When I use your link, I don't encounter [Server error: could not save one or more files. Please try again later!], but during the export "App Inventor is unable to compile this project. The compiler error output was" Can you advise me on this? Or do I need to fix my block code first to match the media files that I deleted? I have no knowledge in this area.

[Maz]

Thank you for this advice. Even though I'm not proficient in your language, I understand the meaning. But when it comes to blocks, I really need to use a lot of blocks, most of them will be in Screen2 >90%.

[Maz]

Are you interested in the .aia file?

[Maz]

"I will try to separate the code blocks into other scenes so that it can export successfully."

Thank you very much , Mr.Taifun

@Maz

most of them will be in Screen2 >90%

which means, you have around 25.000 blocks in that screen

@Maz

Are you interested in the .aia file

I'm sorry, but I do not offer a service of restructuring large projects for free
I only can suggest to follow the already given advice

@Maz

"I will try to separate the code blocks into other scenes so that it can export successfully."

yes, this is another strategy which might help

"I just realized that my project is big T-T. I did it without even planning, just wanted to give it a try.

Thank you again, Mr.Taifun"
Thank you,Mit

Do you have a way to copy a Component and paste it onto another Screen?

[Maz]

I think it's almost done. **I'll try changing the browser.

@Maz

copy a Component and paste it onto another Screen?

One method is to copy the screen and then delete all you do not need

Reuse Screen Layout/Blocks of a project to another

Have you tried CTRL+C and CTRL+V, or CTRL+INSERT and SHIFT+INSERT? If both not working, you can export the aia of old project and new project. Unzip the old aia, move the relevant blk and scm file into the new aia. And you need change the screen name if necessary, both file name and content of the file. blk and scm both are text based file, can be opened by notepad.
