title: How can I prevent additional navigation bar on top of MasterDetailPage (Xamarin on Android)
body: <p>I am creating an application in Xamarin Forms (4.0) for Android (Android 8.1).
  My main page is a MasterDetailPage where I set the detail page to:  </p>
  
  <pre><code>this.Detail = new NavigationPage(new SomePage());
  </code></pre>
  
  <p>When I want to navigate the detail to another page (so that the 'back' button works correctly) I just do:</p>
  
  <pre><code>this.Detail.Navigation.PushAsync(new NavigationPage(new SomeOtherPage());
  </code></pre>
  
  <p>This all works fine but I am left with an additionl navigation bar with the back button:</p>

  <p>If I do <code>NavigationPage.SetHasBackButton(this, false);</code> the back button goes away but the navigation bar is left so I have a big blue rectangle on top of my page. If I do <code>NavigationPage.SetHasNavigationBar(this, false);</code> then both the navigation bar <strong>and</strong> the titlebar (with hamburger menu) dissappear! Is there a way to just hide the navigation bar with the back button but leave the master/detail title bar (with hamburger menu)?</p>
