IAP 구매 후 GUI 업데이트, IAPv3 - Android

Question

InAppBilling API의 v3에서 IAP를 사용하는 방법을 마침내 알아 냈습니다. 이제 사용자는 원하는만큼의 제품을 지속적으로 소비 할 수 있습니다.

이제 구매가 완료되면 사용자 GUI를 업데이트하고 싶습니다. 토스트를 아래의 코드 전체에 넣고 GUI를 업데이트 할 위치를 찾으려고했지만 토스트가 아직 나타나지 않았습니다. 그러나 IAP 소비가 효과적이라는 것을 기억하십시오.

아래의 코드에서 사용자의 GUI를 업데이트하는 스 니펫을 확인했습니다. 코드 스 니펫은 성공적인 구매가 완료된 후 실행하려는 것입니다.

내 질문은 성공적인 구매 후 사용자를 위해 GUI가 업데이트되도록 코드 스 니펫을 넣는 위치입니다.

Answer 1

Google Play 구매 대화 상자를 열려면 구매 의도와 함께 startIntentSenderForResult() 메소드를 사용해야합니다. 이 대화 상자로 사용자가 완료되면 활동에 onActivityResult()이 호출됩니다. 필요한 경우 구매를 확인하고 GUI를 업데이트해야하는 곳입니다.

구매 대화 상자를 여는 방법의 예입니다.

public void buyProduct() { 
    PendingIntent buyIntent = ... // create your intent here 
    IntentSender sender = buyIntent.getIntentSender(); 
    try { 
     startIntentSenderForResult(sender, REQ_BUY_PRODUCT, new Intent(), 0, 0, 0); 
    } catch (SendIntentException e) { 
     Log.e(TAG, "", e); 
    } 
} 

이 두 방법은 사용자의 작업에 속하는 구매 의도

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (requestCode == REQ_BUY_PRODUCT && resultCode == Activity.RESULT_OK) { 
     // here you verify data intent and update your GUI 
     ... 
     return; 
    } 
} 

을 처리하는 방법의 예입니다.
