I have used this code from documentation link 

https://developer.tizen.org/help/topic/org.tizen.native.appprogramming/html/guide/app/appcontrol_contact.htm

It works and i can show the multiple contacts picker. My problem is that i cannot manage to get selected contacts name and phone.

I try OnAppControlCompleteResponseReceived to manage the selected contacts but the only value i can get is the key http://tizen.org/appcontrol/data/social/phone and a random number as a value.
