title: How to send/open email attachments from android app?
body: <p>I would like to somehow send a file from my app on one android device to my app on another device.  This can be done any which way, and I'm open to suggestions if you can tell me how to send over network or something like that.  </p>
  
  <p>Currently, I'm looking at sending the file as an email attachment, but I haven't found any good documentation on how to do it.  I need two things to accomplish this, be able to send my file (stored on sd card or somewhere on device) as an attachment, and have my app recognized by android as the app to open an attachment with the file extention (.lst).</p>
  
  <p>Any thoughts?</p>
  
  <p>The files will all be fairly small xml text files if that makes a difference.</p>
