Trying to integrate hilt using android Api Documentation but app crashed with following exception. https://developer.android.com/training/dependency-injection/hilt-android

java.lang.RuntimeException: Unable to start activity 
ComponentInfo{com.package.application/com.package.application.MainActivity}: 

java.lang.ClassCastException: com.package.application.DaggerAppApplication_HiltComponents_ApplicationC$ActivityRetainedCImpl$ActivityCImpl

Answer 1

What worked for me:

1. Removed the @AndroidEntryPoint annotation from the activity.
2. Ran the code and of course, it failed.
3. Had a fragment inside the activity. So, I deleted the fragment code as well.
4. Ran the code, it failed.
5. Added the @AndroidEntryPoint annotation to the activity again.
6. Ran the code. It ran and the error disappeared.
