title: Android: Send e-mail with attachment automatically in the background
body: <p>I am making an app that allows the user to take a picture and send it automatically via email to the email he chooses. So far I was able to take a picture and store in the SD card. Now I only need functions that get the picture from the folder (/sdcard/Pictures/PhotoSender/) and send automatically to the e-mail the user has requested. How can I do this?</p>
  
  <p>I have the picture in that folder. I just need some functions to generate the e-mail, put the picture (.jpg) as an attachment and send (all this on background). When the e-mail gets totally sent, a toast should pop up saying "Upload Done". Meanwhile the user should be free to take more pictures, so the uploading requests should be put on a queue. The user shouldn't login with his e-mail account to send. If needed, I can create an e-mail account for my app to be the "sender". Please help me!</p>
