3. Restart android studio

Answer 4

Couldn't resolve resource @string/faq_customer_service or Couldn't resolve resource @id/visible or Couldn't resolve resource @id/masked The solution is if you implement TextInputLayout the above problems may arise ... so Simply add those id or strings to xml files as their property.

Answer 5

The only reliable way I've found so far is reloading the project / restarting Android Studio.

Quickest way to do that is File → Invalidate caches / Restart... → Just Restart.

Right click on project and Synchronize '...Project' worked for me.
