Unable to import Content Negotiation and Serializable imports in kotlin Android Studio

Question

I am creating an app on andoird studio and I need to be able to do JSON serialization.However , I am not able to use imports such as

import io.ktor.serialization.kotlinx.json.*
import io.ktor.server.plugins.contentnegotiation.*
import io.ktor.serialization.kotlinx.json.*

etc even though I have added the required dependencies.

This is my project level gradle

import com.android.build.gradle.AppExtension
import com.android.build.gradle.internal.crash.afterEvaluate

buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:8.1.4")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.22")
        classpath("com.google.gms:google-services:4.4.1")
        val kotlinVersion = "1.9.22"
        classpath(kotlin("serialization", version = kotlinVersion))
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
    // Add the following code to ensure namespace is set for all Android modules
    subprojects {
        afterEvaluate { project ->
            if (project.hasProperty("android")) {
                (project.extensions.getByType(AppExtension::class.java) as AppExtension).run {
                    if (namespace == null) {
                        namespace = project.group as String
                    }
                }
            }
        }
    }
}

rootProject.buildDir = file("../build")
subprojects {
    project.buildDir = file("${rootProject.buildDir}/${project.name}")
}
tasks.register("clean") {
    doLast {
        delete(rootProject.buildDir)
    }
}

and this is my module level gradle

plugins {
    id("com.android.application")
    id("org.jetbrains.kotlin.android")
    id("com.google.gms.google-services")
    id("kotlinx-serialization")
}

android {
    namespace = "com.example.prosubscriberapp"
    compileSdk = 34

    defaultConfig {
        applicationId = "com.example.prosubscriberapp"
        minSdk = 26
        targetSdk = 34
        versionCode = 1
        versionName = "1.0"

        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
        vectorDrawables {
            useSupportLibrary = true
        }
    }

    buildTypes {
        release {
            isMinifyEnabled = false
            proguardFiles(
                getDefaultProguardFile("proguard-android-optimize.txt"),
                "proguard-rules.pro"
            )
        }
    }
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = "1.8"
    }
    buildFeatures {
        compose = true
    }
    composeOptions {
        kotlinCompilerExtensionVersion = "1.5.1"
    }
    packaging {
        resources {
            excludes += "/META-INF/{AL2.0,LGPL2.1}"
        }
    }
