I'm developing Sip Client for Android. And I need this library to complete my project. there is an open source code using this library but i can't find it anywhere

A well-known open-source Android SIP client CSipSimple relies on PJSIP which has a dual, GPL + probably commercial, license.

As of Android 2.3 I believe, there is android.net.sip included in the SDK.
