Too many arguments for public open fun navigateUp()

I created a new Android project in Kotlin. I also created a new Navigation Drawer Activity using the wizard. As always nothing works out of the box.

The following lines showed a compilation error:

val navController = findNavController(R.id.nav_host_fragment)

I had to import the method and add the first argument 🤦🏻‍♂:

import androidx.navigation.Navigation.findNavController
...
val navController = findNavController(this, R.id.nav_host_fragment)

Now the next line shows a compilation error:

val navController = findNavController(this, R.id.nav_host_fragment)
return navController.navigateUp(appBarConfiguration) // does not compile

Error:

"Too many arguments for public open fun navigateUp(): Boolean defined in androidx.navigation.NavController"

I have the following dependency in my gradle configuration:

implementation 'androidx.navigation:navigation-ui-ktx:2.0.0'

It contains the NavController.kt file, which contains the extension function. Where's the problem?

I tried to reproduce your problem but it works for me. Check if you have proper imports

Instead of yours:

import androidx.navigation.findNavController

I have:

import androidx.navigation.Navigation.findNavController

And for navigateUp:

import androidx.navigation.ui.navigateUp
