永远不会调用Google InAppBilling onPurchaseStateChange

onClick

requestPurchase(String productId, String payload)

    @Override
    public void onClick(View view) {
        if(view == requestPurchaseButton) {
            mBillingService.requestPurchase(\"android.test.purchased\", \"10\");
        }
    }

responseCode

RESULT_OK

       @Override
       public void onRequestPurchaseResponse(RequestPurchase request,
                ResponseCode responseCode) 
       {
              if(responseCode == ResponseCode.RESULT_OK) {
            Log.d(\"AJ\", \"onRequestPurchaseResponse.ResponeCode.RESULT_OK\");
            textView.append(request.mProductId + \"\\n\");
          } else if(responseCode == ResponseCode.RESULT_USER_CANCELED) {
                      //doesn\'t go here
          } else { 
                     //doesn\'t go here
          }
       }

    @Override
        public void onPurchaseStateChange(PurchaseState purchaseState,
                String itemId, int quantity, long purchaseTime,
                String developerPayload) {
            Log.d(\"AJ\", \"onPurchaseStateChanged\");

        }
