Question

我在android.Below中进行Inapp计费版本3应用程序是我的代码。在这里Inapp Billing已经启动，购得很好并且它出现了＆＃34; onProductPurchased＆＃34;方法。但是如何获得响应代码？谢谢。

代码：

 private BillingProcessor bp;
    bp = new BillingProcessor(this, LICENSE_KEY,
                new BillingProcessor.IBillingHandler() {
                    @Override
                    public void onProductPurchased(String productId,
                            TransactionDetails details) {

                        //How to get response code from here?
                        showToast("onProductPurchased: " + productId);
                        updateTextViews();
                    }


                    @Override
                    public void onBillingError(int errorCode, Throwable error) {
                        showToast("onBillingError: "
                                + Integer.toString(errorCode));
                    }

                    @Override
                    public void onBillingInitialized() {
                        showToast("onBillingInitialized");
                        readyToPurchase = true;
                        updateTextViews();
                    }


                    @Override
                    public void onPurchaseHistoryRestored() {
                        showToast("onPurchaseHistoryRestored");
                        for (String sku : bp.listOwnedProducts())
                            Log.d(LOG_TAG, "Owned Managed Product: " + sku);
                        for (String sku : bp.listOwnedSubscriptions())
                            Log.d(LOG_TAG, "Owned Subscription: " + sku);
                        updateTextViews();
