do you intend to implement this on desktop?

[Mathieu, 2016/07/27 21:35:53]

Android first, desktop is currently a "maybe" according to PM.

[Evan Stade, 2016/07/29 17:02:51]

can you compile less of this (i.e. the entire class) on non-android then?

+  if (!IsAutofillCreditCardAssistEnabled() || credit_card_form_data_)
+    return false;
+
+  for (FormStructure* cur_form : base::Reversed(form_structures)) {
+    if (cur_form->IsCompleteCreditCardForm()) {
+      credit_card_form_data_.reset(new FormData(cur_form->ToFormData()));
+      break;
+    }
+  }
+  return !!credit_card_form_data_;
+#endif
+}

+void AssistManager::ShowAssistForCreditCard(const CreditCard& card) {

+      card, base::Bind(&AssistManager::OnUserDidAcceptCreditCardFill,
+                       weak_ptr_factory_.GetWeakPtr(), card));
+}

+                                        credit_card_form_data_->fields[0], card,
+                                        base::ASCIIToUTF16(""));

[Evan Stade, 2016/07/27 16:42:40]

base::string16()

[Mathieu, 2016/07/27 21:35:53]

Done.
