I have a similar issue but I have Gruntfile in app designer folder but when I type in “grunt” in terminal I get an error feedback as “a valid Gruntfile could not be found”. I didn’t install android studio, I installed only android command line tool, could that be the problem ? Do I need to install android studio before I can use app designer ? @elmps2018 @RJP
