Android Contacts API 2 example

Hi, Abhilash !

I realized your requirements yesterday finally and edited some lines of code.

The following program works well on my Android real device(Android 2.3.6, Galaxy S, 2010, Samsung in Korea).

Not tested on AVD emulator because there is no contacts on my AVD but I used Eclipse Indigo.

I hope this helps.

Thank you.
