Question

通过firebase-ui启动电话身份验证后，我从Leakcanary获得了下一个泄漏报告。我不认为我做错了什么。

我也从ConstraintLayout和SubmitConfirmation中泄漏代码片段

Answer 1

这是LibraryLeak，这意味着它是库或Android框架代码中的已知泄漏。在底部，您可以看到模式：

模式：实例字段android.view.ViewGroup $ ViewLocationHolder＃mRoot，

说明：在Android P中，ViewLocationHolder具有一个mRoot字段，该字段可以   不会在其clear（）方法中清除。引入   https://github.com/aosp-mirror/platform_frameworks_base/commit/86b326012813f09d8f1de7d6d26c986a909d   错误报告：https://issuetracker.google.com/issues/112792715
