Forward mails to mobile as an SMS

I am trying to create an application, which send out an SMS as soon as you receive a mail in your email account. I have an SMS API, which will take care of sending th开发者_如何学JAVAe SMS to a particular mobile number. What I am now concerned is, how do I let my application know that a mail has been received. For simplicity sake I will be using the Gmail account. So as soon as I receive a mail on my Gmail id I want a sms to be sent to my mobile, which has the senders address as well as the subject.

Any suggestions as to how can i let my application know about it?

Thanks

You have to poll Gmail from time to time. You can use IMAP or just parse the feed provided by gmail.

Does Gmail have a Data API?

No, but you can use Gmail's Atom feed with AuthSub or OAuth to request read-only access to a user's unread messages. The scope should be set to https://mail.google.com/mail/feed/atom/
