title: Cannot resolve symbol 'CalligraphyContextWrapper'
body: <p>Till yesterday everything was working fine but today i have updated my <code>Android studio</code> from <strong>2.3 to 3.1</strong> and i am getting this error now. But even i am getting <code>Cannot resolve symbol CalligraphyContextWrapper</code>, still project is successfully <code>clean</code> and <code>build</code> and the <code>font</code> is changing fine. I am surprised if everything is working fine then why this error appears. You can see the error in image and also i am adding my <strong>gradle</strong> code below. Please let me know if i am doing something wrong.</p>
