title: Error inflating class android.webkit.WebView happens sporadically in production
body: <p>my application is on Google Play and it runs fine on most of devices (thousands of users). But in rare cases (fraction of percent of daily active users) I get <code>Error inflating class android.webkit.WebView</code> when I inflate layout for my fragment in <code>onCreateView</code> method.
  Full stack trace is following:</p>

  <p>I don't understand what's wrong. Because this error comes from online reporting tool (Crashlytics/Fabric), I can't tell, whether this happens every time the specific user tries to use the fragment or if the user normally gets the fragment inflated and the error happens only from time to time.
  WebView widget is part of the system, right? I mean - I can't be missing something in my production APK - like support library or so. Or can I?</p>
