What is difference between ActivityRetainedComponent @ActivityRetainedScope and ActivityComponent @ActivityScoped in dagger hilt android

Answer 1

Based on the documents. ActivityRetainedComponent lives across configuration changes, so it is created at the first onCreate and last onDestroy, and when you mark your dependencies in ActivityRetainedComponent with @ActivityRetainedScope its guarantees that your object will be a singleton and survive across configuration changes. But ActivityComponent created at onCreate and destroyed at onDestroy. and when you mark your dependencies in ActivityComponent with @ActivityScope its guarantees that your object will be a singleton but ActivityComponent will be destroyed in configuration changes.

Answer 2

@ActivityRetainedScope will safe guard from configuration changes such screen orientation or language changes.
