Android AOSP Contacts app and Calls.VOICEMAIL_TYPE -

I am trying to create a contact app with AOP as an Android project in Eclipse. I can not get the reference

the call. VOICEMAIL_TYPE

CallLogFragmentTest.java in the code

  Private Zero Insert Voicemail (string number, long date, int period) {object [] value = getValuesToInsert (number, date, Period, call .VOICEMAIL_TYPE); // should be the same value as the row value [CallOiloco. VOICEMAIL_URI] = ContentUris.withAppendedId (Voicemail Contract. Voicemail.contENT_URI, mIndex); InsertValues ​​(value); }   
 Even the VOICEMAIL_TYPE variable is not present in my other Android environment?  
 Has anyone done this, what do you really use?   
 
 
  CallLog.Calls  is found in VOICEMAIL_TYPE  View as you can from  
  
 
 
 You do not have all the right source code (i.e., your copy  call log  In  VOICEMAIL_TYPE    
 
 You actually set up an Android project (with a  android.jar)  As part of your build path), because  VOICEMAIL_TYPE  is marked as  @hide , this While it may be part of an OS build, it is not part of the Android SDK    
 In addition to other factors.
