This is the first time I've encountered this issue with Studio. For both the project and app level files, when I double click to open build.gradle I get the following problems:
Android Studio 2.3 - File opens, but displays "Loading" indefinitely.
Android Studio 3.0 - File doesn't even open at all. Clicking on them does nothing.
Has anyone else seen this behavior before? And solutions? Advice would be appreciated.
