Android应用内结算:购买后收到空白数据

Question

我正在尝试实施应用内结算.我已登录到在Market注册的测试帐户,并且我已在代码中更新了我的公钥.我可以购买其中一个测试产品ID.

但是,似乎在PURCHASE_STATE_CHANGED意图中发送了空白签名.日志显示如下:

INFO/BillingReceiver(21437): notifyId: android.test.purchased
WARN/ActivityManager(2513): Duplicate finish request for HistoryRecord{47de4b38 com.android.vending/.billing.InAppBuyPageActivity}

"购买未经验证"是由于代码跳过签名验证(因为它是空白的)并且抛弃了产品购买.

任何的想法？我没有在文档中看到签名可能是空白的或原因是什么.

FWIW,这只发生在我的三星Vibrant Galaxy S(2.2.1)上.它在Droid(2.2.2)上工作正常.

编辑:当我得到PURCHASE_STATE_CHANGED意图作为恢复事务操作的结果时,我在日志中得到了这个:

INFO/BillingService(24010): handleCommand() action: com.android.vending.billing.PURCHASE_STATE_CHANGED
ERROR/Security(24010): data is null

这表明根本没有发送签名的有效负载.

编辑:在进一步测试时,似乎这发生在上传的应用程序的版本和安装的应用程序不同时.http://code.google.com/p/marketbilling/issues/detail?id=15

我也遇到了这个问题。我增加了 apk 的 versionCode，对其进行了正确签名，但随后只从市场得到了这些空响应。

为了解决这个问题，我将新的 apk 作为草稿上传到市场，然后我得到了有效的回复。
