LeakActivity Leaked 在 Leak Canary 上显示

Question

这个 activity 不是我的应用程序的一部分，它一直显示在 Leak Canary 应用程序上。

它甚至似乎与 activity 我运行以及我是否打开应用程序完全无关。

我在过去 12 小时内收到此消息总共 6 次

谁能帮忙解释一下？

这是 Android 框架 (ViewGroup.ViewLocationHolder) 中的已知漏洞：https://github.com/square/leakcanary/issues/1081

LeakCanary 实际上是这样识别它的，这就是它被报告为 "LibraryLeak" 的原因。请参阅该线程以了解可能修复它的方法（这很难，因为它是 android 框架中的错误）。
