I am looking to streamline some data I record about my cars. My current approach is a manually edited spreadsheet with a ton of columns, which I must fill in at every fill-up and servicing. I have begun creating an android app which will save to a hosted database instead, but I'd like to simplify it even further. Rather than requiring input such as Odometer, trip, oil life, etc, I'd like to grab those from the OBD-II diagnostic port.

I've seen several which have their own applications, but I am looking for one which supports third party polling and APIs. Has anyone had any experience with this?

    Are you looking to give your app the ability to read data directly from OBD-II scanners? If so, apps like Torque are able to communicate with a large amount of scanners because CAN has a lot of documentation about it. – valsidalv Dec 22 '14 at 16:15
  • I'm looking to build my own app for personal use (and just practice with android) so I'd prefer a scanner which is open, rather than another app which can communicate. I will look in to that however. – Adam Yost Dec 23 '14 at 17:21

in general these ODB2 Bluetooth adapters are working with a modem protocol with AT commands. So basically you can connect to them via Bluetooth serial protocol and send in commands. A starting point in terms of documentation and which Bluetooth adapter to get is here:
