App Immediatley crashes once app runs with error ClassNotFoundException: Didn't find class application on path: DexPathList

Question

Starting a new project and I am experiencing the following error... I have tried other solutions but seem to be dated

Steps I have tried:

Double checked plugins (listed below)
Instance Run (not listed)
tried using kapt in-place of annotationProccessor (produces a different error)

class CoreApplication : Application()

when using kapt instead of annotationProccessor

public final class CoreApplication extends android.app.Application {
             ^
  Expected @HiltAndroidApp to have a value. Did you forget to apply the Gradle Plugin? (dagger.hilt.android.plugin)
  See https://dagger.dev/hilt/gradle-setup.html
  [Hilt] Processing did not complete. See error above for details.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:kaptDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask$KaptExecutionWorkAction
   > java.lang.reflect.InvocationTargetException (no error message)

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

UPDATE

Implemented with Dagger2 error is gone... maybe this is due to a bug within the Hilt library

`tried using kapt in-place of annotationProccessor (produces a different error)` , What's that error? — Sujal Kumar, Feb 08 '22 at 03:25
Your error message mentions a `CIRCULAR REFERENCE` in Hilt regarding your Application class. Is it possible that you defined this class in the wrong place? Is your application class set in the `` tag in the Manifest? Also double-check if your setup Multidex correctly. https://developer.android.com/studio/build/multidex — muetzenflo, Feb 08 '22 at 09:02
@muetzenflo I pasted the manifest code above and set multidex to true — onStackOverflowListener, Feb 08 '22 at 17:44
just a wild guess. Could you try to remove the underscore from your package name: `transfertracker`? — muetzenflo, Feb 08 '22 at 18:54
You can try disabling it temporary in your `project.gradle` (or comment it by putting a double slash in front of it) and see if it still produce an error. If it does, include the content of `proguard-rules.pro` in your question. — Darkman, Feb 09 '22 at 18:25
@muetzenflo resolved ```CIRCULAR REFERENCE```.. believe this was due to using midSDK 22 as multidexing is automatically enabled as of 21 (Android 5.0) — onStackOverflowListener, Feb 09 '22 at 18:40

After adding these dependencies everything works fine

implementation 'com.google.dagger:hilt-android:2.40.5'
implementation 'androidx.navigation:navigation-fragment-ktx:2.4.0'
implementation 'androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03'
annotationProcessor 'androidx.hilt:hilt-compiler:1.0.0'
annotationProcessor 'com.google.dagger:hilt-android-compiler:2.38.1'

I had the same problem.

Got it resolved by removing this from AndroidManifest.xml

<application
    
      android:name="com.package.name.Application" <- Remove this entire line

Before that I tired invalidating caches, Project Clean, delete build, .gradle and .idea folders, upgraded everything to the latest versions. Nothing else worked.

Try extending the CoreApplication class with MultiDexApplication like this:

@HiltAndroidApp
class CoreApplication : MultiDexApplication() {...}

I think your Application class is getting saved in a different Dex file.

Trying to keep them in a single Dex file should work.

Try this Procedure

Suggestion:

To check Dex file classes you can use Android Studio, open your apk into Android Studio. You can see your dex files in the apk explorer.

Then select the dex file to see what classes are inside it.
