I have just created a new project in Kotlin and I wanted to add navigation and safe args in it.
I have created 2 fragment (DishListFragment, DishDetailFragment) and an nav graph with action to one fragment to another in it. I have added one button to my first fragment and set a on click listener using view binding:
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
binding.deneme.setOnClickListener {
val action = DishListFragmentDirections.actionDishListFragmentToDishDetailFragment()
findNavController().navigate(action)
}
}
but when I try to create a direction action named DishListFragmentDirections
android studio giving me red errors saying:
Unresolved reference: DishListFragmentDirections
and says I should create DishListFragmentDirections
class.
Things I have tried:
Into my app level build.gradle
, I have added:
implementation(libs.androidx.navigation.safe.args.generator)
implementation(libs.androidx.navigation.safe.args.gradle.plugin)
I have tried invalidating caches and rebuilding my project but nothing helped me. I have tried doing things in doc but I think they have changed structure or something.
Module build.gradle.kts
plugins {
alias(libs.plugins.androidApplication)
alias(libs.plugins.jetbrainsKotlinAndroid)
}
android {
namespace = "com.example.myapplication"
compileSdk = 34
defaultConfig {
applicationId = "com.example.myapplication"
minSdk = 24
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
}
}

testImplementation(libs.junit)
androidTestImplementation(libs.androidx.junit)
androidTestImplementation(libs.androidx.espresso.core)
}
Project build.gradle.kts
// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
alias(libs.plugins.androidApplication) apply false
alias(libs.plugins.jetbrainsKotlinAndroid) apply false
}
I know I'm a bit late to the conversation, but here's how I resolved the issue. You can update your Gradle files accordingly. I hope this helps anyone struggling with adding dependencies.
