ArrayList content_provider_operation=new ArrayList();
       content_provider_operation.add(ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI).withValue(ContactsContract.RawContacts.ACCOUNT_TYPE,null).withValue(ContactsContract.RawContacts.ACCOUNT_NAME, null).build());
               //Display Name
       if (name1 != null) {
           content_provider_operation.add(ContentProviderOperation
                .newInsert(ContactsContract.Data.CONTENT_URI)
                .withValueBackReference(
                  ContactsContract.Data.RAW_CONTACT_ID, 0)
                .withValue(
                  ContactsContract.Data.MIMETYPE,
                  ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE)
                .withValue(
                  ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME,
                  name1).build());
           }
       //Mobile Number
       if (mobile_number1 != null) {
                   content_provider_operation.add(ContentProviderOperation
                        .newInsert(ContactsContract.Data.CONTENT_URI)
                        .withValueBackReference(

                        .withValue(ContactsContract.CommonDataKinds.Phone.TYPE,
                          ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE)
                        .build());
                   }
       if(home_number1!=null)
       {
           content_provider_operation.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)
                   .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
                   .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE)
                   .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, home_number1)
                   .withValue(ContactsContract.CommonDataKinds.Phone.TYPE,ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE)
                   .build());
       }
   //   if()
           try {
                  ctc.getContentResolver()
                    .applyBatch(ContactsContract.AUTHORITY, content_provider_operation);
               } catch (Exception e) {
                  e.printStackTrace();
                  //show exception in toast
                  Toast.makeText(ctc, "Exception: " + e.getMessage(),
                    Toast.LENGTH_SHORT).show();
