Android Studio waiting for build to finish
What worked for me was, from the top menu:
Build -> Clean
Build -> Rebuild Project
After that the xml design worked
You can do the following:
"File > Sync Project with Gradle files" (worked for me)
File > Invalidate Cache & Restart > Just Restart
OR
File > Invalidate Cache & Restart > Invalidate & Restart
Close Project and Re-Import the Project
File -> Sync project with Gradle files
I've just run into the exact same problem. I simply solved it by choosing Sync Project with Gradle Files
. This will trigger a Gradle re-import and a build.
As of Android Studio v3.2, the icon is located near the top right tool bar. You can also find it using Find Action
shortcut CtrlShiftA.
