I'm afraid this marks the start of a downfall... I had to hit "Clean project" on Android Studio.

Context:
So when I started developing Android apps I was using Eclipse. Not saying it's the worst IDE out there, but something is definitely screwed when hitting Clean and then Build project for the seventh time in a row without touching any code somehow magically fixes all your problems. Anyway, not complaining too much since I switched to Android Studio before I could say I mastered Eclipse and whatever feature would have helped back then.
Having to turn back to such dark magics is a blast from the past.

Wait till you experience Visual Studio, which can be even more random at times, denying you click to code forwards completely for example and then if you copy even a single button from the project to a rescue project it fucks it there too, so you have to copy paste just the code 😫

@JoshBent in my experience with Visual Studio even Ctrl-Z can severely screw stuff
As in instead of undoing an edit, it might just delete a whole chunk of code

For sure there's dark magic hardcoded in android studio, sometimes shit goes crazy!

@htlr I've already ordered some candles and chalk, any suggestions on what specific rituals to perform?

@Ares4TW Gradle Build and wait 😂😂

Be happy to use Android Studio, cleaning is a normal activity in Xcode 😓
Followed by new indexing ...
