使用片段和导航组件泄漏了nestedscrollView

问题描述

我有一个从leack canary泄漏的垃圾堆，但不知如何解决。

@H_404_2@┬─── │ GC Root: System class │ ├─ android.view.inputmethod.InputMethodManager class │ Leaking: NO (InputMethodManager↓ is not leaking and a class is never leaking) │ ↓ static InputMethodManager.sInstance ├─ android.view.inputmethod.InputMethodManager instance │ Leaking: NO (InputMethodManager is a singleton) │ ↓ InputMethodManager.mCurrentInputConnection │ ~~~~~~~~~~~~~~~~~~~~~~~ ├─ com.android.internal.widget.EditableInputConnection instance │ Leaking: UNKNowN │ ↓ EditableInputConnection.mTargetView │ ~~~~~~~~~~~ ├─ androidx.appcompat.widget.AppCompatEditText instance │ Leaking: YES (View detached and has parent) │ mContext instance of .android.SIActivity with mDestroyed = false │ View#mParent is set │ View#mAttachInfo is null (view detached) │ View.mID = R.id.name │ View.mWindowAttachCount = 1 │ ↓ AppCompatEditText.mParent ├─ androidx.constraintlayout.widget.ConstraintLayout instance │ Leaking: YES (AppCompatEditText↑ is leaking and View detached and has parent) │ mContext instance of .android.SIActivity with mDestroyed = false │ View#mParent is set │ View#mAttachInfo is null (view detached) │ View.mID = R.id.containerName │ View.mWindowAttachCount = 1 │ ↓ ConstraintLayout.mParent ├─ androidx.constraintlayout.widget.ConstraintLayout instance │ Leaking: YES (ConstraintLayout↑ is leaking and View detached and has parent) │ mContext instance of .android.SIActivity with mDestroyed = false │ View#mParent is set │ View#mAttachInfo is null (view detached) │ View.mWindowAttachCount = 1 │ ↓ ConstraintLayout.mParent ╰→ androidx.core.widget.nestedScrollView instance ​ Leaking: YES (ObjectWatcher was watching this because .android.si.SILeadInfoFragment received Fragment#onDestroyView() callback (references to its views should be cleared to prevent leaks)) ​ key = a7452263-5234-4656-9425-754c455f1b06 ​ watchDurationMillis = 11855 ​ retainedDurationMillis = 6853 ​ mContext instance of .android.SIActivity with mDestroyed = false ​ View#mParent is null ​ View#mAttachInfo is null (view detached) ​ View.mWindowAttachCount = 1

应用程序的某些背景： 它正在使用jetpack的导航组件 里面有很多表格处理

任何想法，谢谢！

解决方法

这个问题似乎很老，但我不时遇到这个问题，所以这是我目前所知道的：

• 除了使用反射之外，我还没有找到任何解决方案。
• LeakCanary 2.6 已将此标记为库泄漏（当然，由于 OutOfMemory 异常，它仍然是可能导致应用崩溃的泄漏）。
