Android app with off-site processing

I'm won开发者_StackOverflow社区dering what would be a good way to build an Android application with offsite processing. Essentially I am going to record an input (audio recording or photo), and then send it to a computer I have online (securely - probably using HTTPS). I then will have the computer process the data and send back a response.

Essentially this is a Shazam like application, except everywhere I look to how Shazam works they talk about the processing algorithm, not the process. Any help would be appreciated.

If your server processing may take time, you can use Push Notification to tell the application that you are done on the server side. The application can then get the result instead of holding up the connection for too long.
