Obfuscate Parcelable classes with proguard

I'm trying to obfuscate a parcelable class with Proguard: Before adding the Parcelable part the class is: ``` public class Foo{ private String value; public String getValue() { return value; } public void setValue(String value) { this.value = value; } } ``` The obfuscated result is: ``` public class a { private String a; public String a() { return this.a; } public void a(String paramString) { this.a = paramString; } } ``` After adding implementing parcelable the example class is ``` public class Foo implements Parcelable { private String value; private Foo(Parcel in) { value = in.readString(); } public Foo() { } public String getValue() { return value; } public void setValue(String value) { this.value = value; } @Override public int describeContents() { return 0; } @Override public void writeToParcel(Parcel dest, int flags) { dest.writeString(value); } public static final Parcelable.Creator<Foo> CREATOR = new Parcelable.Creator<Foo>() { public Foo createFromParcel(Parcel in) { return new Foo(in); } public Foo[] newArray(int size) { return new Foo[size]; } }; } ``` The obfuscated result is ``` public class Foo implements Parcelable { public static final Parcelable.Creator CREATOR = new a(); private String a; public Foo() { } private Foo(Parcel paramParcel) { this.a = paramParcel.readString(); } public String a() { return this.a; } public void a(String paramString) { this.a = paramString; } public int describeContents() { return 0; } public void writeToParcel(Parcel paramParcel, int paramInt) { paramParcel.writeString(this.a); } } class a implements Parcelable.Creator { public Foo a(Parcel paramParcel) { return new Foo(paramParcel, null); } public Foo[] a(int paramInt) { return new Foo[paramInt]; } } ``` How can I configure proguard for obfuscate the whole class (including name, params and methods) except the parcelable part? Thanks
