you can use navigation component library for solve this problem!

this will be your nav_graph.xml

<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/nav_graph"
    app:startDestination="@id/AFragment">


    <fragment
        android:id="@+id/AFragment"
        android:name="ir.inbo.navigationComponenetBug.AFragment"
        android:label="AFragment"
        tools:layout="@layout/fragment_a">

        <argument
            android:name="someLong"
            app:argType="long" />
        <action
            android:id="@+id/action_AFragment_to_BFragment"
            app:destination="@id/BFragment" />
    </fragment>
    <fragment
        android:id="@+id/BFragment"
        android:name="ir.inbo.navigationComponenetBug.BFragment"
        android:label="BFragment"
        tools:layout="@layout/fragment_b">

        <argument
            android:name="someLong"
            app:argType="long" />
        <action
            android:id="@+id/action_BFragment_to_CFragment"
            app:destination="@id/CFragment" />
    </fragment>
    <fragment
        android:id="@+id/CFragment"
        android:name="ir.inbo.navigationComponenetBug.CFragment"
        android:label="CFragment"
        tools:layout="@layout/fragment_c" >

        <argument
            android:name="someLong"
            app:argType="long" />
        <action
            android:id="@+id/action_CFragment_to_AFragment"
            app:destination="@id/AFragment"
            app:popUpTo="@id/AFragment"
            app:popUpToInclusive="true" />
    </fragment>
</navigation>

and in AFragment you must move your logic to onViewCreated or onCreateView because of the fragment life cycle when you navigate from AFragment to Bfragment, Afragment's view will be destroyed and when you come back to Afragment from Cfragment, onViewCreated and onViewCreate will be called

and this is google example for your exact use case
