Answer 1

As I maintain a bluetooth OBD Android application, I'll give you some directions.

Start with the Bluetooth Chat sample application to learn the basics of communicating with a bluetooth serial device. Then study the ELM327 Programmers Guide to learn the specifics of the protocol. Checkout existing projects for ideas.

existing projects , which contains swings and awt , but those are not supported by android? is that a good example for beginner ? – Materiality

This is a fair criticism. Here's some more projects to look through on github I've included projects that mention the ST1110 as it is a much better chip that is compatible with the ELM327 command set. But still, I'd really encourage you to learn and fully understand the bluetooth chat app, as a beginner to android you'll need to learn to implement services for things like bluetooth communication. – Amyl

Thank you for your encouragement. i understood blue tooth chat app functionality like scanning for devices , how it connecting and hoe it retrieving and sending messages in it, but now i need help to understand how to work with obd elm327 in android . – Materiality

Answer 2

I want to suggest android-obd-reader (Android OBD-II Reader application that uses pure OBD-II PID's Java API.) example which helps you to get more idea about developing app using OBD-II.

See OBD-II Java API which also help you.
