In my project I have lots of sealed classes implementing certain interface.

interface Intent

sealed classes HomeIntent : Intent {
  data class TextChanged(val text: String) : HomeIntent
  object Exit : HomeIntent
}

I want to keep all the sealed classes like

HomeIntent

, with all of the sub- data classes and objects extending sealed classes. How would you tackle it without adding @Keep to every

selead class

, every

object

and every

data class

? I tried this:

-keepclasseswithmembers class ** implements my.package.Intent {
    **;
}

-keepnames class ** implements my.package.Intent {
    **;
}

but it doesn't seem to keep objects' names. Any ideas?

Does anyone know if Proguard can rearrange the order of parameters in a function?

Newbie here, 🙌🏻 I want to ask, What is the difference between R8 and proguard?

A dexguard question, while using dexguard and creating release build. I am getting the below error :

Not optimizing method 'packageToClass/ActualClass.method(Landroid/graphics/Canvas;Landroid/graphics/Paint;IIIIILjava/lang/CharSequence;III)V'

Unexpected error while shrinking instructions after partial evaluation:

Class    = [{}]

Method   = [{}{}]

Exception  = [{}] ({})

com.guardsquare.dexguard.bkt: Unexpected error while marking instruction usage after partial evaluation:

Class    = [{}]

Method   = [{}{}]

Exception  = [{}] ({})

Anyone is having any idea. I tried with keep, dontwarn etc. without any luck.
