我遇到一个间歇性的问题，在应用程序内结算版本使用IABHelper 3由谷歌提供的。

I'm experiencing an intermittent problem with In App Billing Version 3 using IABHelper as provided by Google.

在启动一个新的采购我检查未用完的采购与queryInventoryAsync。如果发现我消耗任何未使用的采购，并开始一个新的事务，如果不是直接去启动一个新的事务。 99％的时间正常工作。

Before Launching a new purchase I check for unconsumed purchases with queryInventoryAsync. If found I consume any unconsumed purchases and begin a new transaction, if not go directly to start a new transaction. 99% of the time it works fine.

有时候，当queryInventoryAsync返回任何未使用的购买，以下launchPurchaseFlow失败，响应：7：项目已经拥有

Occasionally when queryInventoryAsync returns no unconsumed purchases, the following launchPurchaseFlow fails with Response : 7: Item already owned.

INFO    [IABHelper] Starting async operation: refresh inventory
INFO    [IABHelper] Querying owned items, item type: inapp
INFO    [IABHelper] Package name: jp.co.mycompany.myapp
INFO    [IABHelper] Calling getPurchases with continuation token: null
INFO    [IABHelper] Owned items response: 0
INFO    [IABHelper] Continuation token: null

INFO    [IABHelper] Constructing buy intent for jp.co.mycompany.myapp.myitem, item type: inapp

INFO    [IABHelper] Ending async operation: launchPurchaseFlow
INFO    [IABHelper] Purchase canceled - Response: 7:Item Already Owned

queryInventoryAsync是说用户不拥有该项目，但launchPurchaseFlow说用户一样。

queryInventoryAsync is saying the user does not own the item, but launchPurchaseFlow says the user does.

后，奇怪的是等待（有时是几分钟，有时甚至更多）的问题自行解决。

Strangely after a wait (sometimes a few minutes, sometimes more) the problem resolves itself.

任何人都经历了类似的话？

Has anyone experienced anything similar?

谷歌做了明确的缓存播放服务的应用程序在移动。它可能为你工作。

Do clear cache of Google Play Service app in mobile. It may work for you.
