I am trying to implement dagger Hilt in an android app that uses Jetpack Compose. I have previously used Hilt but this is the first time with a compose project.
This is the error that I get when I try to run the app:
java.lang.RuntimeException: Unable to instantiate application com.juegosdemesa.saltaconejo.SaltaConejoApplication: java.lang.ClassNotFoundException: Didn't find class "com.juegosdemesa.saltaconejo.SaltaConejoApplication" on path: DexPathList[[dex file "/data/data/com.juegosdemesa.saltaconejo/code_cache/.overlay/base.apk/classes7.dex", zip file "/data/app/~~fvjcQ4ZxOw99F2GO-9kvnw==/com.juegosdemesa.saltaconejo-DffqHuQR9C6r5HE_rQmgJw==/base.apk"],nativeLibraryDirectories=[/data/app/~~fvjcQ4ZxOw99F2GO-9kvnw==/com.juegosdemesa.saltaconejo-DffqHuQR9C6r5HE_rQmgJw==/lib/x86, /system/lib, /system_ext/lib]]

[CIRCULAR REFERENCE:java.lang.NoClassDefFoundError: Failed resolution of: Lcom/juegosdemesa/saltaconejo/Hilt_SaltaConejoApplication;]
I understand that the application cannot find the MainActivity.
Here is the code of the activity:
import android.os.Bundle
import androidx.activity.ComponentActivity
import androidx.activity.compose.setContent
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.Surface
import androidx.compose.ui.Modifier
import com.juegosdemesa.saltaconejo.ui.theme.SaltaConejoTheme
import dagger.hilt.android.AndroidEntryPoint
@AndroidEntryPoint
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
SaltaConejoTheme {
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colorScheme.background
) {
SaltaConejoApp()
}
}
}
}
}
Here is the AndroidManisfest:

The Application class:
@HiltAndroidApp

plugins {
id("com.android.application") version "8.2.1" apply false
id("org.jetbrains.kotlin.android") version "1.9.0" apply false
id("com.google.devtools.ksp") version "1.9.0-1.0.13" apply false
id("com.google.dagger.hilt.android") version "2.44" apply false
}
I used a previous working project as an example (no compose though) but still no good.
Also I tried to used kapt for Hilt but in that case the app does not compile and all the feedback I get is java.lang.reflect.InvocationTargetException (no error message) which is not helpful at all
As a workaround I used this codelab as an example and the app compiles and works perfectly https://developer.android.com/codelabs/basic-android-kotlin-compose-persisting-data-room?hl=es-419#10
Any idea on what might happen?
Thank you in advanced
You need to do few modifications in dependencies:
In build.gradle.kts - project level
id("org.jetbrains.kotlin.android") version "1.9.10" apply false
id("com.google.devtools.ksp") version "1.9.10-1.0.13" apply false
id("com.google.dagger.hilt.android") version "2.47" apply false
And in build.gradle.kts - app module
composeOptions {
kotlinCompilerExtensionVersion = "1.5.3"
}
//Hilt
val hiltVersion = 2.47
implementation ("com.google.dagger:hilt-android:$hiltVersion")
kapt ("com.google.dagger:hilt-android-compiler:$hiltVersion")
implementation ("androidx.hilt:hilt-navigation-compose:1.0.0")
