我已经在我的开发控制台创建了5个项目(产品)，但是当使用QueryInventory来获取项目的SkuDetails时，它只返回其中的4个，所以当试图获取未获取产品的详细信息时，我得到一个空指针异常。
而且，有时它只返回其中一个项，有时它不返回任何项。
是否可能有时Google只返回一些(而不是全部)产品?
我希望有人能帮我找出原因:
在这个运行中我没有得到item4
mHelper内部。startSetup
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);
queryInventoryListener:
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();
这五个项目在Google Play Developers Console中都是活跃的。
