    XMPPConnection closed during file transfer from Android to Spark

    yab

      My app crashes after the user on Spark accepts the file for transfer. Can anyone help me find out why this happens?

      My logcat :

      What I know is that a NullPointerException is returned when trying to write the xml to send to the server side. What I dont know is why it will return null and because it returns null, it causes my XMPPConnection connection to close.

      Any feedback is appreciated.
