I need to update my code style. Reformatting the whole project files one by one takes too much effort with the shortcuts I know.
Opt + Command + L
My Question?
Is there any other way to do it for the whole project?
Use the re-format code shortcut (default: ⌘ + Opt + L (Mac) / Ctrl + Alt + L (PC)) in the Project Files View/Explorer on the desired root folder(s) and then check Include subdirectories.
 
    
    This is how it works in Android Studio 3.5
Right click in your project or lib -> Reformat Code
See the image below:
Select what you want (clean up code will reformat your code)

Wait until the progress finish.
that's it!
Good coding!
