One weird issue I am facing while using NavGraph. Whenever <- (back button) selected in toolbar, soft keyboard is not closed automatically. Seems a bug in AndroidX navigation. Has anyone faced this issue?

It's not an AndroidX issue, but when you move between fragments the keyboard doesn't dismiss automatically, as it would going between activities.

Look at the accepted answer to this as a way to dismiss. It could be triggered in your fragments onStop or you could register onBackPressed listener

Intercept the back button click and dismiss the keyboard before navigating up

fun Fragment.hideKeyboardAndNavigateUp() {
    // The keyboard is not dismissed when navigating back. This happens when keyboard is visible and user navigates up (back arrow)
    // Intercept the back button, dismiss keyboard and keep it moving :)
    hideKeyboard()
    findNavController().navigateUp()
}

Thank you guys.
@voben, does it mean this code to be duplicated in all destination fragments?

@voben, I got it. Added a OnDestinationChangedListener() in Activity hosting NavHostFragment and called this method from `

onDestinationChanged
