Avoid to popback to specific fragment with Navigation Architecture Component

Question

I have two navigation flow with Navigation Architecture Component :

A > B > C

And

A > X > C

In the first flow, popBackStack() works as expected. But I want a different behavior in the second flow. I dont want to popback to Fragment X but directly to Fragment A.

Because Fragment C is accessible by several ways, I can't use a fixed destinationId in popBackStack(destinationId,inclusive).

Any solution ? May be navigation direction config ?

Answer 1

Use this action for x to c.

<fragment
android:id="@+id/x"
...
>
 <action
            android:id="@+id/action_X_to_C"
            app:destination="@id/C"
            app:popUpTo="@id/A" >
        </action>
</fragment>

In fragmentX

findNavController().navigate(R.id.action_x_to_C)
