build gradle project:

// Top-level build file where you can add configuration options common 

to all sub-projects/modules. buildscript {

  ext {
      version_navigation = "2.3.0"
       kotlin_version = "1.4.32"
  }

repositories {
    google()
    jcenter()
}
dependencies {
    classpath "com.android.tools.build:gradle:4.1.0"
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"


    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}}
allprojects {
repositories {
    google()
    jcenter()
}}

 task clean(type: Delete) {
delete rootProject.buildDir}

build gradle module:

 plugins {

}

 android {
compileSdkVersion 32
buildToolsVersion "30.0.3"

buildFeatures{

Answer 1

What you have to do is the following:

In the build.gradle (project version), find where you have the ext { } and put this inside:

navigationVersion = "2.3.0"

Then, in the build.gradle (module), inside the dependencies { } you have to put theese two dependencies:

implementation "androidx.navigation:navigation-fragment-ktx:$navigationVersion"
implementation "androidx.navigation:navigation-ui-ktx:$navigationVersion"

And finally, Sync project with gradle files and Rebuild it to make sure everything is okay.

You can change the navigationVersion to the one that you are using on the project gradle.

Then follow this codelab if you encounter some extra problems.
