AndrOBD

AndrOBD allows your Android device to connect to your car's on-board diagnostics system via any ELM327 compatible OBD adapter, display various information & perform operations. It is open source and completely free. The application also has a built in Demo mode that simulates live data, so you don't require an adapter to test it.
