title: How to use Internal API's
body: <p>I want to use com.android.internal.telephony API's in my project, For that I downloaded "framework_intermediates-classes-full-debug.jar" and added to my project. I am able to import Call.java class but not CallManager.java class. I think I downloaded older version of jar file which does't included CallManager class. then Where I get new version of this jar file which includes CallManager class.</p>
  
  <p>Thanks in advance.</p>
