title: Activity flags on Android
body: <p>Just a quick question, as I couldn't quite understand it from the documentation.</p>
  
  <p>If I set a flag - any flag, or several flags - on an <code>Intent</code> prior to launch, is this flag cleared when the <code>Activity</code> starts or is it persistent? What I mean is that let's say I have an <code>Intent</code> and apply  <code>FLAG_ACTIVITY_CLEAR_TOP</code> to it - it will launch with this flag every time, or just once after I set it?</p>
