title: Missing Classes in Android Studio layout folder .xml file
body: <p><a href="https://github.com/spelfit/SpelFit" rel="nofollow noreferrer">https://github.com/spelfit/SpelFit</a></p>
  
  <p>I am having an issue with my Android app. This is my first one I have a login and register page so far. The fields for email, password and confirm password are not displaying. The error says that two classes are missing but I defined them in the Layout folder <code>activity_login.xml</code></p>
  
  <p><strong>following classes could not be found:</strong></p>
  
  <blockquote>
    <p>- android.support.design.widget.TextInputEditText (Fix Build Path, Edit XML, Create Class)
    - android.support.design.widget.TextInputLayout (Fix Build Path, Edit XML, Create Class)</p>
