title: Other activity is also brought to front on StartActivity
body: <p>I have two activities (<strong>A</strong> and <strong>B</strong>) in my app and some <strong>BroadcastReceiver</strong>.</p>
  
  <p>I encounter the following scenario:</p>
  
  <p><strong>A</strong> is running and was closed using the home button (onStop was called).</p>
  
  <p>Some time after, <strong>BroadcastReceiver</strong> was triggered with some intent. It run the following code:</p>
  
  <pre><code>            Intent activityIntent = new Intent(context,
                      B.class);
              activityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK
                      | Intent.FLAG_ACTIVITY_CLEAR_TOP);
  
              context.startActivity(activityIntent);
  </code></pre>
  
  <p>And <strong>B</strong> is indeed started, however <strong>A</strong> is also brought to front (behind <strong>B</strong>). How could I avoid <strong>A</strong> being fronted? </p>
