Component used: Navigation
Version used: 1.0.0-alpha09
Devices/Android versions reproduced on: Android 9 emulator

In our app, we use multiple NavHostFragment in one Activity, few of them have their own navGraph set in xml, say nav_subgraph_1, nav_subgraph_2.

In code, we use NavDeepLinkBuilder to navigate to a specified page.
NavDeepLinkBuilder(it)
        .setGraph(R.navigation.nav_subgraph_1)
        .setDestination(R.id.dest_in_subgraph1)
        .createTaskStackBuilder()
        .startActivities()

It leads a crash in setContentView since the dest_in_subgraph1 couldn't be found in nav_subgraph_2 (while parsing the second NavHostFragment in the same Activity)
