title: Open fragment from notification when the app in background
body: <p>I am using parse to push <code>Json</code> notifications to my app with custom receiver because I want to navigate to different places in the app and that's depends on <code>Json</code> value I receive, I have 2 cases to navigate:</p>
  
  <p>a) 7</p>
  
  <p>b) 1, 2, 3, 4, 5, 6</p>
  
  <p>case <code>a</code> opens an <code>activity</code> and that's works as normal.
  case <code>b</code> open a <code>fragment</code> in the `MainActivity. "Here's the problem."</p>
  
  <p>I tried to open the <code>MainActivity</code> with normal intent then replace the container of it with the fragment.</p>
  
  <p>When I try to open case <code>b</code> I got <code>ClassCastException</code> in the third line from this snippet because it's cannot cast the <code>BaseClass</code> context to v4 fragment.
  I got the same exception when I give it just the <code>context</code> that belongs to the receiver context.</p>
  
  <pre><code>intent = new Intent(context, MainScreen.class);
  Fragment fragment = new NotificationFragment();
  FragmentTransaction transaction = ((FragmentActivity) context.getApplicationContext()).getSupportFragmentManager().beginTransaction();
  transaction.replace(R.id.container, fragment).commit();
  </code></pre>
  
  <p>That's the exception:</p>
