我在我的开发者控制台中创建了5个项目（产品），但是当使用QueryInventory获取项目的SkuDetails时，它只返回4个项目，因此在尝试获取非详细信息时会出现Null Pointer Exception - 提取产品。
此外，有时它只返回其中一个项目，有时它不会返回任何项目。
Google有时会退回一些（而非全部）产品吗？
我希望有人可以帮我找出原因：
在这次运行中，我没有得到item4
在mHelper.startSetup内部
additionalSkuList.add(SKU_item1);
additionalSkuList.add(SKU_item2);
additionalSkuList.add(SKU_item3);
additionalSkuList.add(SKU_item4); // this one is missing in the response
additionalSkuList.add(SKU_item5);
mHelper.queryInventoryAsync(true, additionalSkuList,mQueryFinishedListener);
在queryInventoryListener中：
String item1Price =inventory.getSkuDetails(SKU_item1).getPrice();
String item2Price =inventory.getSkuDetails(SKU_item2).getPrice();
String item3Price =inventory.getSkuDetails(SKU_item3).getPrice();
String item4Price =inventory.getSkuDetails(SKU_item4).getPrice(); //Null Pointer Exc. HERE
String item5Price =inventory.getSkuDetails(SKU_item5).getPrice();
并且所有五个项目在Google Play开发者控制台中都显示为有效。
这是Logcat输出

每当您向应用内商品列表中添加新商品时，通常需要15分钟到3小时才能完全传播到所有Google Play服务器。发布您的应用或更新的APK同样如此。不幸的是，您只需要耐心等待，并让服务器有时间处理您的请求。
