Question

我正在使用以下代码在app app中实现。我在我的项目中添加了Blackberry paymentapi.jar。我从下面的链接中引用了这段代码：

                displayButton = new ButtonField("Display Purchases");
                displayButton.setChangeListener(this);
                hfm.add(displayButton);
            }
            else
            {
                RichTextField errorMessage = new RichTextField("Sorry, in-app purchases are unavailable");

            }
        }

        public void fieldChanged(Field field, int context)
        {
            if (field == buyButton)
            {
                String name = digitalGoodName.getText();
                String sku = digitalGoodSku.getText();

                PurchaseArgumentsBuilder arguments = new PurchaseArgumentsBuilder()
                    .withDigitalGoodSku( sku )
                    .withDigitalGoodName( name )
                    .withMetadata( name )
                    .withPurchasingAppName( "Payment Service SDK Demo" );

                try 
                {
                    Purchase purchase = engine.purchase(arguments.build());
                    Dialog.inform("Purchase of " + purchase.getMetadata() 
                        + " is successful.");
                }
                catch (IllegalArgumentException e) 
                {
                    Dialog.inform(e.getMessage());
                }
                catch (PaymentException e) 
                {
                    Dialog.inform(e.getMessage());
                }
            }
            else if (field == displayButton)
            {
                try 
                {
                    Purchase[] purchases = engine.getExistingPurchases(true);

                    if (purchases.length != 0)
                    {
                        if (getFieldCount() > 3)
                        {
                            deleteRange(3, (getFieldCount()-3));
                        }

                        for (int i = 0; i < purchases.length; i++ )
                        {
                            RichTextField purchaseRecord = new RichTextField("Name: " 
                                + purchases[i].getMetadata() + "    SKU: " 
                                + purchases[i].getDigitalGoodSku());
                            add(purchaseRecord);
                        }
                    }
                    else
                    {
                       Dialog.inform("No existing purchases");
                    }       
                } 
                catch (PaymentException e) 
                {
                    Dialog.inform(e.getMessage());
                }
            }
        }                   
    }
}

在上面的代码中

engine.setConnectionMode(PaymentEngine.CONNECTION_MODE_LOCAL);
Purchase[] purchases = engine.getExistingPurchases(true);

显示红色错误。

不再支持PaymentEngine #setConnectionMode（）： http://www.blackberry.com/developers/docs/payment/1.8api/

您仍然可以使用沙盒帐户进行测试： http://docs.blackberry.com/en/developers/deliverables/40131/Live_testing_1935047_11.jsp

Blackberry In App购买getExistingPurchases和PaymentEngine.CONNECTION_MODE_LOCAL显示错误
