I built the app using blocks. Is there any way to look at the source code?
Go to www.appinventortojava.com and login then when you create your app, click on Build then Java bridge, then select
Java file or
Project and java files will be saved.
Does this even still work these days?
It is quite old but only available solution.
Works but not dependent on appinventor. You can create a project there and convert to jave. Unfortunately, this project is based on the old version of app inventor and there aren't many components and methods that are currently in app inventor.
The blocks are the source code. You can look inside the aia file if you want. That is a zip file.
