Answer 1

In your project,

1. Delete {root}/.gradle folder
2. Delete {root}/app/build folder
3. Delete {root}/build folder
4. Run Invalidate Caches / Restart
5. Sync your project again after Android Studio restarts

SOLUTION FOUND!!!

Android Studio does the most dumb thing: it indexes ALL FILES on your PC. Straight to the point: I deleted my downloads and DerivedData folder and all went alright.

A short explanation. . DerivedData became a huge folder with tons of files making Android Studio loop forever on those files . On my Mac the Downloads folder is shared as hard links with multiple apps. for example, the Skype or Steam apps have hard links to the Download folder, making Android Studio re index the entire Downloads folder multiple times.
