How to use Android to read a car's on board diagnostics?

I know that I’ve seen somewhere that you can use an Android device to read a car’s on-board diagnostics (OBD). What do I need to get to be able to do this? I assume it requires at least some sort of cable/usb interface. If so, are they universal or different for every car?

You are going to need a car that is OBD2 compliant and a OBD scan tool adapter. The adaptor will plug into the OBD port on your car. Some of these adaptors use WiFi or Bluetooth to connect to a mobile device (or laptop). You can get one cheap for around $10 on Amazon. http://www.amazon.com/Vgate-Bluetooth-Scanner-TORQUE-ANDROID/dp/B00AAOOQJC/ref=sr_1_2?ie=UTF8&qid=1423165616&sr=8-2&keywords=obd+ii+bluetooth

You will also need an Android app. Torque Pro is popular, and the lite version is free. https://play.google.com/store/apps/details?id=org.prowl.torque

If you don’t want to use Torque, there are other apps. Here is a comparison of some of them. http://techpp.com/2014/03/18/obd-apps/
