This is my DamroApplication.kt file

package lk.ac.kln.mit.stu.mobileapplicationdevelopment

import android.app.Application
import dagger.hilt.android.HiltAndroidApp

@HiltAndroidApp
class DamroApplication : Application() {

}

Here is my folder structure

Below is my AndroidManifest.kt file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <application
