title: How can I link to a phone call link from within an embedded web page in Android?
body: <p>I have an Android application that has one section loading a web page within a frame of the app.</p>
  
  <p>On the webpage, it has a link to call our support line using the <code>tel:123456</code> protocol (i.e. <code>&lt;a href="tel:123456"&gt;&lt;img/&gt;&lt;/a&gt;</code>) and that works exactly as expected within the native Android browser.</p>
  
  <p>However, when the app loads the embedded page (using a WebView) and I click the <code>tel:</code> link, I get the "Web page not available" screen ("The Web page at tel:123456 might be temporarily down or it may...").</p>
  
  <p>I assume I need to handle the protocol in the app somehow but I'm not sure how.  What do I need to do?</p>
