我正在使用Google Play In app Billing并使用IabHelper提交我的请求，其中startIntentSenderForResult使用onActivityResult。
正如预期的那样，完成通话后（Google Play活动结束），结果将返回OnIabPurchaseFinishedListener方法中的我的活动，然后通过IabHelper将其委托给等待的04-03 20:21:14.371: D/com.satalyst.android.ui.PurchaseAction(10129): Launching purchase flow request for sku: demo_test

修复此问题令我感到难过，因为我想在发生购买错误时在我的活动中显示一个对话框，允许他们通过电子邮件向我发送详细信息，以便我可以优先帮助客户解决购买错误。我确信我可以做一些修复工作，可能会在错误发生时保留详细信息并提前返回，然后每次恢复活动以检查持久性故障并采取适当的操作;然而，这感觉就像一个讨厌的工作。

错误日志（完整），显示过早的活动销毁：
{{1}}
答案 0 :(得分：1)
我遇到了尝试实施IAP的类似问题。
我的活动将启动模式设置为“singleInstance”，禁止系统在其任务中启动新活动。
似乎startIntentSenderForResult试图在其任务中启动一个新活动，失败并因此返回null。
当我将启动模式设置为限制较少的“singleTop”时，此问题就消失了。
答案 1 :(得分：1)
我有同样的问题，因为我的活动有标志noHistory
<activity android:name=".BuyActivity" android:screenOrientation="portrait"
android:noHistory="true"/>
当我删除属性时，一切正常
答案 2 :(得分：0)
所以，有两个问题：
查看第一个logcat，看起来调用dialog.show()时发生了故障。我想知道你是否已经确定了上下文 - 我经常发现这是造成这种失败的原因。
没有对话框。正如我从问题和你的评论中理解的那样，核心序列如下。查看完整的日志，我认为Finsky与您正在做的事情密切相关：
W / Finsky（3130）：[1] CarrierParamsAction.run：保存运营商计费参数失败。 E / Finsky（3130）：[184] FileBasedKeyValueStore.delete：尝试删除'params1Fzx-vZz47HyPCTxqb1ncg'失败！ D / Finsky（3130）：[1] GetBillingCountriesAction.run：跳过获取新的结算国家名单。In-app Billing Error表明这个过程可能存在问题（特别是在开发过程中），这可能会被规避。或者，这是您在应用内结算中所期望的行为吗？
除此之外，ActivityManager.getProcessesInErrorState()调用onDestroy可能会很有趣，看看它是否告诉你任何有关出错的信息......
答案 3 :(得分：0)
我的建议是尝试：
runOnUiThread()发布Runnable，打开对话框。
