I’ve been having issues trying to get the layout editor to open on the Mac-OS Android Studio Version 3.5.1. I have been following the Codecademy skill path “Getting Stared with Android Studios” and ran into issues with the “Introduction to Layout Editor” portion. I attempted to follow the course’s steps to open the layout editor, but it did not work. The only difference I found between my Android Studio Window (picture 1 below this text) and the course’s window is that my Main Activity File has an orange circle in the bottom left corner of the file name, while the course window has a blue circle to the left of the file name.
I ran into some issues with the synchronization of Gradle with the Java programs in Android Studio, which I have solved by invalidating and restarting the Android Studio Cache, but this has not solved my issues with the layout editor.
My machine information:
CPU: IMac OS Mojave (10.14.6)
Android Studio version 3.5.1
