"Clean code" does change a lot based on IDEs and programming language. For example, we don't use variable names like mIntScore anymore. And we're finding that Javadocs might add little value and go out of date.

Architecture can change quite a bit too - all the async webs make things difficult. Most of the bug reports we get on mobile are not test coverable. e.g. some jankiness when going back to a page, or something like liking a post three levels down and finding that your like was not registered when you go back towards the home screen. We had some bugs like an OS modding text animations, making the text invisible in very niche situations. Then you have combos of ltr and rtl languages and layouts. Adding test coverage can be 4x the effort of writing the code once with no tests, not to mention the architecture for test support making things exponentially more complex.

Maybe we have to rethink what complete code really means.
