IllegalArgumentException: navigation destination xxx is unknown to this NavController

Question

I am having issue with the new Android Navigation Architecture component when I try to navigate from one Fragment to another, I get this weird error:

Answer 1

A Ridiculous way but very powerful is: Simply call this:

view?.findNavController()?.navigateSafe(action)

Just Create this Extention:

fun NavController.navigateSafe(
    navDirections: NavDirections? = null
) {
    try {
        navDirections?.let {
            this.navigate(navDirections)
        }
    }
    catch (e:Exception)
    {
        e.printStackTrace()
    }
}
