Question

I fetch this below code from

But getting this below error: spend already more the 3 hours but not any success.

Please help me to solve this error.

Answer 1

Change this

  implementation 'android.arch.navigation:navigation-fragment-ktx:2.2.0-alpha01'
  implementation 'android.arch.navigation:navigation-ui-ktx:2.2.0-alpha01'

to this:

  implementation 'androidx.navigation:navigation-fragment-ktx:2.2.0-alpha01'
  implementation 'androidx.navigation:navigation-ui-ktx:2.2.0-alpha01'

Notice that android.arch.navigation is replaced with androidx.navigation

also, make sure to apply this plugin on top of build.gradle:

apply plugin: "androidx.navigation.safeargs.kotlin"

and this to the dependencies to the project level build.gradle:

 classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.1.0-rc01"

Answer 2

If you are using kotlin and androidX than replace this

apply plugin: "androidx.navigation.safeargs"

with

apply plugin: "androidx.navigation.safeargs.kotlin"

and in project level build.gradle

dependencies {
    classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.1.0-alpha01"
}

on app level build.gradle

def nav_version = "2.1.0-alpha01"

implementation "androidx.navigation:navigation-fragment:$nav_version"
implementation "androidx.navigation:navigation-ui:$nav_version" 

If you are using kotlin Ktx

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

Hope this will help other people also. It helps me too
