Rendering Problems Couldn't resolve resource @string/email_hint
I searched this forum and google, to no avail. I think this is an Android Studio bug, but maybe not. I'm doing the "Creating the Screen Layout" extra credit, and this issue has cropped up. I define my strings correctly, and then select them in the hint property of my editText, and I get this error in the preview. When I run the app on the emulator, it works fine, but the design preview shows errors. I tried clean, rebuild. And I tried relaunching AS completely. No luck. Spent more time on this bug than the whole section heh.
According to this stackoverflow post, it is likely just an Android Studio issue and the fastest way around it is to File, Invalidate Caches/Restart. If this doesn't help, please let us know and we can try other things to continue working on this problem.
