title: Android NFC : Tag lost when APDU command sent to a smart card
body: <p>I am doing an EMV application on Android OS (Samsung Galaxy). </p>
  
  <p>I am able to send several APDU commands without problem but when I am trying to send the internal authentication command. I have this error : Tag lost. Have you got any idea concerning the purpose of this error ? I am not an experimented developer on Android, It may I have forgotten some stuff. </p>
  
  <ul>
  <li>the command is correct.</li>
  <li>I can replace by another command, it works (I mean I can recover a response).  </li>
  </ul>
  
  <p>In which cases a NFC communication can be broken on Android? </p>
  
  <p>Here, you can see my problem when the command is sent : </p>
