Main Activity

@AndroidEntryPoint
class MainActivity : AppCompatActivity() {

private lateinit var binding : ActivityMainBinding

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    binding = ActivityMainBinding.inflate(layoutInflater)
    setContentView(binding.root)

}

Hilt Module

@Module
@InstallIn(SingletonComponent::class)
class AppModule {

@Singleton
@Provides
fun provideActivity(): MainActivity = MainActivity()

@Singleton
@Provides
fun provideActivityUtils(@ActivityRetainedScoped context: MainActivity): ActivityUtils = 
ActivityUtilsImpl(context)
}

And utils class with needed functions

class ActivityUtilsImpl @Inject constructor(@ActivityRetainedScoped private val activity: 
MainActivity) : ActivityUtils {

override fun showKeyboard() {
    val imm = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as 
InputMethodManager?
    imm?.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0)
 }
}

When I try to call something from the utils class using an activity instance, I get the error java.lang.IllegalStateException: System services not available to Activities before onCreate ()

Tried @ActivityContext the same thing, how can I make it call normally
