Android Question What is the most advanced free app with source code?

[Rams007]

So either free of paid source code. App should have menus, custom list views and as much other functions as possible.

Or does anyone have source code I can buy?

I think this is a great way to learn

I don't know which app is the "most advanced". You can see a fairly complicated, although not completed yet, app here: https://www.b4x.com/android/forum/t...leroma-mastodon-client-step-1.119426/#content
