title: How to get a url from a pin that can be opened on a webview
body: <p>I am using the Pinterest Android SDK to authenticate and read pins from Boards I follow. 
  The issue is in my app, I need to to open the URL of the pin in a webview to able to read the pin contents in my app itself without leaving my app. 
  Currently, I can use the "url" field from the getPin() API response json, but the URL redirects from the webview to the pinterest app (leaving my app).
  Is there a way to do this?
  Thanks.</p>
