come aggiungere un gruppo di contatti al mio account in Android 4.2

Question

Sto sviluppando un'applicazione per account Android. Ora posso aggiungere il mio account in Android. Ma quando apro l'app Contatti e passa al cercapersone di gruppo, viene visualizzato "Nessun gruppo. Per creare gruppi è necessario un account.". Quindi, come far sapere a Android che il mio account può aggiungere un gruppo?

Qui di seguito è il mio file xml:

AndroidManifest.xml:

<!-- The sync service --> 
    <service 
      android:name="com.snail.android.sync.SyncService" 
      android:exported="true" 
      android:process=":sync"> 

     <intent-filter> 
      <action android:name="android.content.SyncAdapter"/> 
     </intent-filter> 

     <meta-data 
       android:name="android.content.SyncAdapter" 
       android:resource="@xml/contacts_sync_adapter"/> 
     <meta-data 
       android:name="android.provider.CONTACTS_STRUCTURE" 
       android:resource="@xml/contacts"/> 

    </service> 

contacts.xml:

<?xml version="1.0" encoding="utf-8"?> 

<ContactsAccountType> 
    <EditSchema> 
     <!-- 
      Name: 
      - maxOccurs must be 1 
      - No types. 

      - Currently all the supportsXxx attributes must be true, but here's the plan for the 
       future: 
       (There's some hardcoded assumptions in the contact editor, which is one reason 
       for the above restriction) 

       - "Family name" and "Given name" must be supported. 
        - All sync adapters must support structured name. "display name only" is not 
         supported. 
         -> Supporting this would require relatively large changes to 
         the contact editor. 

       - Fields are decided from the attributes: 
        StructuredName.DISPLAY_NAME   if supportsDisplayName == true 
        StructuredName.PREFIX    if supportsPrefix == true 
        StructuredName.FAMILY_NAME   (always) 
        StructuredName.MIDDLE_NAME   if supportsPrefix == true 
        StructuredName.GIVEN_NAME   (always) 
        StructuredName.SUFFIX    if supportsSuffix == true 
        StructuredName.PHONETIC_FAMILY_NAME if supportsPhoneticFamilyName == true 
        StructuredName.PHONETIC_MIDDLE_NAME if supportsPhoneticMiddleName == true 
        StructuredName.PHONETIC_GIVEN_NAME if supportsPhoneticGivenName == true 

       - DataKind.PSEUDO_MIME_TYPE_DISPLAY_NAME is always added. 
       - DataKind.PSEUDO_MIME_TYPE_PHONETIC_NAME is added 
        if any of supportsPhoneticXxx == true
