Code:-

Build.gradle(:app) :-

plugins {
    apply plugin: 'com.android.application'
    apply plugin: 'androidx.navigation.safeargs'
}

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.example.layouteditor"
        minSdkVersion 16
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.3.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'androidx.navigation:navigation-fragment:2.3.5'
    implementation 'androidx.navigation:navigation-ui:2.3.5'
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

build.gradle(LayoutEditor):-

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.1.3"
        def nav_version = "2.3.0-alpha04"
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_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
}

And I get this error:-

A problem occurred configuring root project 'LayoutEditor'.

Could not resolve all artifacts for configuration ':classpath'.
Could not find com.android.tools.build:gradle:4.1.3.
Searched in the following locations:
- https://jcenter.bintray.com/com/android/tools/build/gradle/4.1.3/gradle-4.1.3.pom
If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.

Possible solution:

I have gone through solutions of similar question asked by other on stackoverflow. I have put right code in right gradle file. I tried code from Android developers >> Jetpack >> Libraries (click below link) https://developer.android.com/jetpack/androidx/releases/navigation#safe_args but getting more errors and I have also gone through above Android Studio's suggested possible solution but didn't understand it. Please help if anyone have faced same problem and have solution.

The reason of this is may using a different version of plugin.

Try to use following lines in your build.gradle(LayoutEditor):

classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.3.2"

Instead of

def nav_version = "2.3.0-alpha04" classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"

Use line following lines for apply plugin 'androidx.navigation.safeargs.java'

If you use kotlin then 'androidx.navigation.safeargs.kotlin'

This may solve your problem.

Replace 2.3.0-alpha04 with 2.3.0 or newer version and rebuilt your project. It should work.
