i have recently published my app in android market site. After a month i have added and removed some features in it. By this i have added a map feature and i created a new build using a new keystore, i tried to update my app but it shows an error as follows 

"The apk must be signed with the same certificates as the previous version."

How to resolve this issue. How to know my former keystore values. i use to give the same Organisation name, Country etc but i think i have changed the expiry year. How to update my app with the new keystore

Pls give me some suggestion

You can ONLY update an existing app with the same certificate ("keystore") as original app. There is NO WAY around it.

This has been already asked many times. See This

You must have created 2 files when u uploaded your application. One file is .apk file for market and another file which is the keystore.

When u provide update to the existing app, you'll need the keystore. When u export your project in Eclipse u need to say from existing key and browse the keyfile u created when u used previously.

If you have lost your previous key file, then read this question. It'll help you.
