I am giving the Navigation option a try and must say that so far…..does not make me happy.
It is almost like this is some alpha version of a new feature so many bugs as it has.
Besides the problem you can read al over de place of studio not generating the Directions-classes and how to fix this (clean project + rebuild or invalidate caches) or (remove stuff from gradle -> sync -> re-add) which works by the way, i have a different problem.

When i finally get al the directions-classes to work correctly and i press the run button to test my app in the emulator, all directions-classes seem to be lost.
result: error’s in all my fragments.
I read and tried all but 1 option in this post: stackoverflow post
the 1 option i could not try i the one where the add the path in the gradle:

sourceSets {
getByName("main") {
    java.srcDirs("build/generated/source/navigation-args")
} }

For the simple reason then when i do, i get and error “sourceset with name ‘main’ not found.”
and i have no idea how to solve this.
On the other hand i lost the hope that this is the actual solution to my problem.

below i am posting by 2 gradle files in the hope i made a really stupid misstake then (in which case i owe google a apology for complaining)

module: app

plugins {
alias(libs.plugins.android.application)
alias(libs.plugins.jetbrains.kotlin.android)
id("androidx.navigation.safeargs")
}
android {
namespace = "com.example.tripmemory"
compileSdk = 34

defaultConfig {
    applicationId = "com.example.tripmemory"
    minSdk = 28
    targetSdk = 34
    versionCode = 1
    versionName = "1.0"

    testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
}

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 {
    viewBinding = true
}    
} 
dependencies {

implementation(libs.androidx.core.ktx)
implementation(libs.androidx.appcompat)
implementation(libs.material)
implementation(libs.androidx.constraintlayout)

implementation(libs.androidx.navigation.fragment.ktx)
implementation(libs.androidx.navigation.ui.ktx)
implementation("androidx.navigation:navigation-dynamic-features-fragment:2.7.7")

implementation(libs.androidx.preference.ktx)

implementation(libs.androidx.room.common)
implementation(libs.androidx.room.ktx)

implementation(libs.play.services.maps)
implementation("com.google.android.gms:play-services-location:21.2.0")


testImplementation(libs.junit)
androidTestImplementation(libs.androidx.junit)
androidTestImplementation(libs.androidx.espresso.core) 
}

and the project gradle

buildscript {
dependencies {
    classpath("androidx.navigation:navigation-safe-args-gradle-plugin:2.7.7")
} 
} 
plugins {
alias(libs.plugins.android.application) apply false
alias(libs.plugins.jetbrains.kotlin.android) apply false
id("com.google.android.libraries.mapsplatform.secrets-gradle-plugin") version("2.0.1") apply false 
}

and to be complete: the libs.version

I hope somebody knows how to solve this problem because i like the navigation way of working but at the moment the benefits are disapearing fast.
