How to open Jetpack Navigation Fragment from Notification?

Question

I'm using Jetpack Navigation in my project following image describes my navigation. In my Application Home Fragment is my NavHostFragment and I'm using foreground service in Fragment A. When I navigate from Home Fragment to Fragment A and close the application or minimize then foreground service run with notification. When I pressed notification Home fragment open but I want Fragment A would be open and all back stack would be saved. I'm using MainActivity as a PendingIntent in notification where all my navigation fragments work.

After a long time, I found the solution. In this scenario, Deeplinking will be used. And change PendingIntent from MainActivity to your destination FragmentA.

nav_graph.xml

 <fragment
        android:id="@+id/fragmentA"
        android:name="com.example.FragmentA"
        android:label="Fragment A"
        tools:layout="@layout/fragment_a">
       
        <action
            .../>
        
        <deepLink
            android:id="@+id/deepLink"
            app:uri="www.example.com" />
    </fragment>

AndroidManifest.xml

<application
        ...>
        <activity
            android:name=".MainActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <nav-graph android:value="@navigation/nav_graph"/>
        </activity>
    </application>

PendingIntent

val pendingIntent = NavDeepLinkBuilder(context)
                .setGraph(R.navigation.nav_graph)
                .setDestination(R.id.fragment_a)
                .createPendingIntent()
