Question

Couldn\'t resolve res

Answer 1

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.
