Component used: Navigation
Version used: 1.0.0-alpha09

Since Safe Args currently has the child Directions class extend the parent navigation graph's Directions object, it can fail to compile due to different return types if the parent and child have the same action id and arguments.

<navigation
  android:id="@+id/parent"
  app:startDestination="@+id/child">
  <action
    android:id="@+id/next"
    app:popUpTo="@+id/parent" />
  <fragment
    android:id="@+id/child">
    <action
      android:id="@+id/next
      app:popUpTo="@+id/parent"/>
  </fragment>
</navigation>
