title: Android - Intent ACTION_CALL without call log
body: <p>I want to invoke call action from my Activity, but after call action is finished my app stays on call log screen. To avoid this situation I decide to intent my activity from <code>PhoneStateListener</code>, and I do it like this:</p>
  
  <pre><code>Intent intent = new Intent(MainActivity.this, MainActivity.class);
  intent.setFlag(...);
  startActivity(intent);
  </code></pre>
  
  <p>I tried many combination of flags but only result I get was that my activity wasn't on the front of activity stack or I get new instance of my activity. 
  How can I get my activity (the same instance) on the front of activity stack.</p>
