Can you make apps hooked up to each other

MIT App Inventor Help

Hello there, I was going to make a gallery in mit app inventor about all the apps I made but I came with a problem. I want it to make it easier by making different aia files that connect to one aia file.

Look into the activity starter

Also a package manager extension could help, for example

Can you tell me how I can link my projects

It does not look like you read anything about Activity Starter or the Package Manager extension?

Choose one of the solutions, then try something to start one of your projects to find out what you need...

And make yourself familiar with working with lists

Hey @Randomly_Mythic,
App Inventor doesn’t support linking .aia files directly, but you can connect multiple apps using shared data via Web APIs or Firebase. For example, each app could send info (like its name, image, or link) to a common database, and your gallery app can fetch and display it.

Let me know if you want help setting that up—I’ve done something similar in a multi-app project.

Thanks for correcting that @TIMAI2.
Happy to learn if I misunderstood something. From my experience, .aia files work as independent projects, so I assumed there's no official way to link them directly at runtime like modules.

Would love to know how it can be done—if there's a method or workaround, I'm genuinely interested!

The method was already posted above by @Taifun , I will post it again...

Alternatively you could ask your chatbot ai again...

Appreciate the link, @TIMAI2 and thanks for reposting.
I missed the original reference to Activity Starter.
As for the chatbt, it's only as smart as the prompt, right? :smile:
Appreciate your time!

I don't mean to use this extension for google play I was wondering if I could play the aia file without being connected to anything

12

Would I be able to use like a cloud that would be one app and then a different cloud as another app

13

This is what I am looking for

Please tell me you understand this took a long time to make as a example

Could someone look at this message please it took long to make :pensive:

Hi @Randomly_Mythic,

In MIT App Inventor, you can't directly connect multiple .aia files into one project. Each .aia file is a separate standalone app project. However, you can work around this by:

  1. Creating a Main Gallery App: This app can have buttons or a list that opens your other apps.
  2. Using Activity Starter: Use the Activity Starter component to launch other apps installed on the same device. You'll need the package name of each app.
  3. Export and Install All Apps: Export your other .aia files as .apk and install them on the device for Activity Starter to open them.

This method doesn't merge .aia files but links them in a user-friendly way.

Hope this helps!
