我正在做 Android Wear 项目。通知显示给用户contentAction，因此用户可以点击它。录音后，它SomeActivity会显示DelayedConfirmationView给用户时间来取消即将到来的 API 请求。当DelayedConfirmationView完成 API 调用时。API调用成功后ConfirmationActivity显示。当ConfirmationActivity返回我们finish() SomeActivity并取消通知。
我面临的问题是，在 SomeActivity 启动后，它会无缘无故地神秘停止。与崩溃一起的日志如下所示：

我尝试了很多事情来让它发挥作用，但没有真正奏效。有任何想法吗？DelayedConfirmationView会造成这样的不良行为吗？我在网上看到了一些例子，他们甚至开始了它onCreate，所以它不可能是它。
最困扰我的是在onPause之前调用了onStop。这很奇怪。在SomeActivity您可以看到，onStop我与 GoogleApiClient 断开连接但 Activity 仍然存在，因为日志显示它在 Activity 启动后 3 秒尝试调用 API（3 秒需要 DelayedConfirmationView 完成）。问题是这个活动没有显示给用户，因为神秘onStop被调用了。
