Answer 1

None of the single solutions above where sufficient for me. I had the same issue after updating from android studio 2.3.3 to 3.1.2.

1. Close Android Studio
2. Remove .idea/workspace.xml
3. Restart android studio (your project with the issue is opened automatically)
4. A new .idea/workspace.xml is created
5. Sync project with gradle files
6. Open File -> Settings - > Plugins -> Enable
   • "Android Support" Plugin.
   • Android NDK support (I had to disable and re-enable it)
7. Restart Android Studio
