title: Kill activity when already active
body: <p>For a notification I am using an Intent to start an Activity. However, when that activity is already active, it comes to the front.</p>
  
  <p>I don't want this to happen, but I'd like it to be restarted. I don't want multiple instances, so in the manifest I added launchMode singleTask.</p>
  
  <p>Any ideas?</p>
