Do I need to 'keep' Parcelable in proguard rules while obfuscating

Question

My Project has few classes that extends Parcelable. Do I need to 'keep' them in proguard rules while obfuscating.

What is the general practice for parcelables?

No. But if you are using the same class for JSON parsing using GSON then use serializedName tag with field name. — Pankaj Kumar, Mar 18 '16 at 05:36
Yes you need, as mentioned in http://stackoverflow.com/a/20918277/3050249 — Miha_x64, May 16 '17 at 13:25

No, the default android rules include this:

-keepclassmembers class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator CREATOR;
}

These default rules will be applied if you leave the default generated gradle definition in place:

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

Make sure you do not forget the 'final' in your field definition! That was in my case the reason, why proguard removed it still.. – allofmex Dec 11 '19 at 19:22

If you are using Kotlin @Parcelize with proguard you can add this to proguard-rules.pro:

-keep @kotlinx.android.parcel.Parcelize public class *

`kotlinx.android.parcel.Parcelize` is deprecated in favor of `kotlinx.parcelize.Parcelize` so this may need changing to `-keep @kotlinx.parcelize.Parcelize public class *` – Scott Cooper Oct 07 '22 at 10:54
