title: Detect anonymous / incognito browsing
body: <p>The Android default browser allows anonymous browsing. Is it possible to detect when the user is browsing in an incognito tab of the default Android browser application? (I have no interest in the url the user is visiting)</p>
  
  <p>I am using a Content Observer object to receive updates on the user browsing history. When the user opens an Incognito tab, I don't receive any update, as anyone would expect. What I was wondering is how could I know that the user is browsing anonymously. </p>
  
  <p>I can know that the Browser app is on foreground, and I know that no history url is being registered, but what other information could I retrieve to be sure the user is browsing in an incognito tab?</p>
  
  <p><strong>UPDATE</strong>:</p>
  
  <p>Guys, thank you for your comments. I know exactly what I am asking. I know the point of incognito mode and that only the default Browser uses the <code>ContentProvider</code> for logging the browsing history.</p>
  
  <p>I am writing a parental control app, so I would very much appreciate if anyone could answer the question. </p>
