无法使用Xamarin.Android中的Xamarin.Mobile组件保存联系人

Question

我在Xamarin.Android项目中使用这个Xamarin.Mobile组件.经过大量的谷歌搜索和他们的样本,我发现只有从电话到我的应用程序检索联系人的方式.

以下是我的代码:

        AddressBook book = new AddressBook(context)
            {
                    PreferContactAggregation = true
            };



        Phone ph = new Phone(){
        Type = PhoneType.Mobile,
        Number = "9952429044"
        };

       Contact ct = new Contact()
        {
            DisplayName = "Sai Ram",
            FirstName = "Om",
            MiddleName = "Sai",
            LastName = "Ram",
            Phones = new List<Phone>(){ph}
        };

我需要将Contact对象保存到手机的地址簿中.我找不到像任何方法book.Save(contact)在Xamarin.Contacts.

Xamarin.Mobile只有API用于阅读联系人,而不是用于添加.

以下是如何使用手机号码向联系人添加新联系人的简短示例.

List<ContentProviderOperation> ops = new List<ContentProviderOperation>();
int rawContactInsertIndex = ops.Count;

ops.Add(ContentProviderOperation.NewInsert(Android.Provider.ContactsContract.RawContacts.ContentUri)
    .WithValue(Android.Provider.ContactsContract.RawContacts.InterfaceConsts.AccountType, null)
    .WithValue(Android.Provider.ContactsContract.RawContacts.InterfaceConsts.AccountName, null).Build());
ops.Add(ContentProviderOperation
    .NewInsert(Android.Provider.ContactsContract.Data.ContentUri)
    .WithValueBackReference(Android.Provider.ContactsContract.Data.InterfaceConsts.RawContactId,rawContactInsertIndex)
    .WithValue(Android.Provider.ContactsContract.Data.InterfaceConsts.Mimetype, Android.Provider.ContactsContract.CommonDataKinds.StructuredName.ContentItemType)
    .WithValue(Android.Provider.ContactsContract.CommonDataKinds.StructuredName.DisplayName, "Vikas Patidar") // Name of the person
    .Build());
ops.Add(ContentProviderOperation
    .NewInsert(Android.Provider.ContactsContract.Data.ContentUri)
    .WithValueBackReference(
        ContactsContract.Data.InterfaceConsts.RawContactId, rawContactInsertIndex)
    .WithValue(Android.Provider.ContactsContract.Data.InterfaceConsts.Mimetype, Android.Provider.ContactsContract.CommonDataKinds.Phone.ContentItemType)
    .WithValue(Android.Provider.ContactsContract.CommonDataKinds.Phone.Number, "9999999999") // Number of the person
    .WithValue(Android.Provider.ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Type, "mobile").Build()); // Type of mobile number  

// Asking the Contact provider to create a new contact                 
try {
    ContentResolver.ApplyBatch(ContactsContract.Authority, ops);
} catch (Exception ex) {
    Toast.MakeText(this, "Exception: " + ex.Message, ToastLength.Long).Show();
}
