使用proguard混淆Parcelable类 [英] Obfuscate Parcelable classes with proguard

问题描述

我正在尝试使用Proguard混淆可包裹类:

I'm trying to obfuscate a parcelable class with Proguard:

在添加Parcelable部件之前，该类为:

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;
    }

}

混淆的结果是:

public class a
{
  private String a;

  public String a()
  {
    return this.a;
  }

  public void a(String paramString)
  {
    this.a = paramString;
  }
}

添加实现可打包的示例类后

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];
        }
    };
}

混淆的结果是

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];
    }
}

我如何配置proguard来模糊除可包裹部分之外的整个类(包括名称，参数和方法)?

How can I configure proguard for obfuscate the whole class (including name, params and methods) except the parcelable part?

谢谢

推荐答案

尝试将其放入您的proguard.cfg文件中:

Try putting this in your proguard.cfg file:

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

这应该保留Parcelable的一部分，并混淆其他所有内容.

That should preserve Parcelable part and obfuscate everything else.
