How to clear navigation Stack after navigating to another fragment in Android

• First, add attributes app:popUpTo='your_nav_graph_id' and app:popUpToInclusive="true" to the action tag.

 <fragment  
   android:id="@+id/signInFragment"  
   android:name="com.glee.incog2.android.fragment.SignInFragment"  
   android:label="fragment_sign_in"  
   tools:layout="@layout/fragment_sign_in" >  
   <action  
     android:id="@+id/action_signInFragment_to_usersFragment"  
     app:destination="@id/usersFragment"  
     app:launchSingleTop="true"  
     app:popUpTo="@+id/main_nav_graph"  
     app:popUpToInclusive="true" />  
 </fragment>  

• Second, navigate to the destination, using above action as parameter.

 findNavController(fragment).navigate(
     SignInFragmentDirections.actionSignInFragmentToUserNameFragment()) 

• Programitically navigate to the destination with clear previous stack

 val navOptions: NavOptions = NavOptions.Builder().apply {  
         setPopUpTo(R.id.navigation, true)  
         setLaunchSingleTop(true)  
       }.build()  
       navController.navigate(R.id.destination_fragment, null, navOptions)
