android - Send email in background service without a popup -

I want to send an email with an attachment (image). I am using a background service and should not have any intention. Now I am looking for the best solution. I thought of the JavaMail API, but I'm not sure this would be the best solution. Another option image may be uploaded to send mail and a php script may be used. Is it a good idea because of the traffic for upload?

It is possible to send mail without popup / user interaction without jammail I tried it myself There are very good documents I think it does not matter whether you send the image by mail or upload it somewhere or using some other solution due to the same file traffic will be in all cases. If you want to reduce the traffic, you can zip the image, reduce the quality ...
