In this application I tried to read the contacts and store them in one file. But when I tried to run this application it gives me following error as.

What is the problem in this code.

[Ankit Garg]

I created a new project in eclipse and used your code and it worked fine on Android 2.0 simulator (except for IOException because the required directories were not there)...
