Navigate from fragment of one graph to fragment of another graph with bundle

Question

I have two graphs nav_graph1.xml and nav_graph2.xml(in two different modules/lib)

I want to navigate from fragment1 to fragment2 with bundles. How do i achieve using navigation component?

nav_graph1.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_graph1"
    app:startDestination="@id/fragment1">
    <fragment
        android:id="@+id/C1_fragment"
        android:name="com.example.multiplenavigation.C_nav_graph.C1 "
        android:label="C1"
        tools:layout="@layout/fragment_C1">
        <action
            android:id="@+id/C1_to_C2_fragment"
            app:destination="@id/C2_fragment" />
    </fragment>
</navigation>

nav_graph2.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_graph1"
    app:startDestination="@id/fragment2">
    <fragment
        android:id="@+id/fragment2"
        android:name="com.example.multiplenavigation.C_nav_graph.C1 "
        android:label="C2"
        tools:layout="@layout/fragment_C2">
    </fragment>
</navigation>

First, create a nested navGraph by including the second graph in the first.

Then, if your destination fragment is not the start fragment of the second graph you need to use Uri as shown here in this answer: navigate to a fragment from another graph without it being the start destination

Since you can't pass a bundle with Uri navigation, to pass the bundle you need something like a method to set and get the bundle on your activity, setting bundle from first fragment and get it in onCreate of the second fragment.

No, I use single activity in app, and I have two feature modules and each has its own nav graph – Ananth Jul 06 '20 at 08:46
@Ananth Your feature modules are dynamic ? – Jasurbek Jul 06 '20 at 13:19
@Jasurbek No, they are not dynamic modules – Ananth Jul 06 '20 at 14:19
@Ananth Have you checked my answer? – Sina Jul 06 '20 at 14:21
Both your module? or external module? – Jasurbek Jul 06 '20 at 14:21
