I have one app and one dynamic feature module i wish to navigate from
App nav graph
<?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_graph"
app:startDestination="@id/mainFragment">
<!-- Main Fragment from App Module -->
<fragment
android:id="@+id/mainFragment"
android:name="com.xyz.MainFragment"
android:label="MainFragment"
tools:layout="@layout/fragment_main">
<action
android:id="@+id/action_mainFragment_to_nav_graph_home"
app:destination="@id/nav_graph_home" />
</fragment>
<!-- Home Navigation from App Module-->
<include app:graph="@navigation/nav_graph_home" />
<include-dynamic
android:id="@+id/nav_graph_dashboard"
android:name="com.feature.dashboard"
app:graphResName="nav_graph_dashboard"
app:moduleName="dashboard" />
</navigation>
And feature navigation
<?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_graph_dashboard"
app:moduleName="dashboard"
app:startDestination="@id/dashboardFragment1">
<fragment
android:id="@+id/dashboardFragment1"
android:name="com.feature.DashboardFragment1"
android:label="DashboardFragment1">
</fragment>
</navigation>
Returns error
java.lang.IllegalStateException: The included <navigation>'s id com.xyz.dashboard:id/nav_graph_dashboard is different from the destination id com.xyz:id/nav_graph_dashboard. Either remove the <navigation> id or make them match.
It seems that removing id from feature navigation solves the issue but i couldn't find how to make them match even though both <include-dynamic>
and <navigation>
have the same id android:id="@+id/nav_graph_dashboard"
I don't need id for <navigation>
for this example but i wonder if it's possible when <navigation>
has one
Remove the +
from your ID in your feature navigation graph:
android:id="@id/nav_graph_dashboard"
When you use the @+id
syntax, you create a new ID in your dynamic feature's package (you'll note the exception explicitly calls out the package names for each resource ID for exactly that reason). By removing the +
, you use the already created ID from the main module's package, which makes them match.
