title: how to add an action to copy/pase or listen to copy event on android
body: <p>Hie!</p>
  
  <p>I'm trying to develop an app that will do one of these 2 options - </p>
  
  <ol>
  <li><p>whenever a user marks a text in any app (using the regular copy/paste), there will be another option besides copy/cut that will open my app. (preferred)</p></li>
  <li><p>My app would listen to a copy text event in another app and will show a notification to the user. when they press it, it will open my app. </p></li>
  </ol>
  
  <p>I haven't found a way to do either of these options.Some claim that I can listen to the copy activity but I couldn't understand how to do it(<a href="https://stackoverflow.com/questions/5944541/android-how-to-listen-to-long">Android : How to listen to longclick events in any text area in other applications?</a> click-events-in-any-text-area-in-other-application).</p>
  
  <p>I'm not looking for anyone to write the code for me of course, just a pointer to the right direction if this is possible.</p>
  
  <p>Thanks in advance,
  Shahar</p>
