Hey I need to read Taxi Meter Data from serial port using Android. Tell me some possible ways to implement it...

I need to get Amount, Start time, End time, Waiting time etc from meter and display it in Android text view.

This is actually up to the taxi meter device. Android can just supply you with USB support (Host or Accessory mode). You can find the relevant documentation here:

http://developer.android.com/guide/topics/connectivity/usb/index.html

Once obtained a working communication channel, it is up to the taxi meter device to define which data are made available and how they can be read/used. You will need the taxi meter documentation for this (or you will have to do a lot of reverse engineering...).

Displaying the data in a view is a task in itself. You will have to read the documentation, design the desired view and populate it with your data. Try to start here:
