设置ProGuard以混淆局部变量和参数

Question

我似乎找不到在混淆的类的方法内部混淆本地变量的设置。

这是我反编译的其中一个类的节选，其中有一些明显的缺失部分。理想情况下，方法的参数和局部变量也将被混淆。

public class eA extends gu
{
  private final gt a;
  private final gt b;

  public static boolean a(fy game)
  {
    boolean playerDead = game.k().j() <= 0;
    boolean enemyDead = game.g().a().size <= 0;
    boolean wavesRemain = game.r() > 0;
    return (playerDead) || ((!wavesRemain) && (enemyDead));
  }

  public eA(gt gameState, gt boardState)
  {
    this.b = gameState;
    this.a = boardState;
  }

  public void a()
  {
    n();
    boolean playerDead = this.f.k().j() <= 0;
    boolean enemyDead = this.f.g().a().size <= 0;
    if (a(this.f)) {
      if (enemyDead) {
        this.f.a(new eG(1));
        this.e.a(new eW());
      } else if (playerDead) {
        this.f.a(new eF());

编辑，我还要附加proguard配置

-dontskipnonpubliclibraryclassmembers
-dontshrink
-dontoptimize
-printmapping build/libs/output/obfuscation.map
-keepattributes
-adaptclassstrings
-dontnote
-dontwarn

# Keep Android classes
-keep class ** extends android.** {
    <fields>;
    <methods>;
}

# Keep serializable classes & fields
-keep class ** extends java.io.Serializable {
    <fields>;
}

# Keep - Applications. Keep all application classes, along with their 'main'
# methods.
-keepclasseswithmembers public class * {
    public static void main(java.lang.String[]);
}

# Also keep - Enumerations. Keep the special static methods that are required in
# enumeration classes.
-keepclassmembers enum  * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

# Keep names - Native method names. Keep all native class/method names.
-keepclasseswithmembers,allowshrinking class * {
    native <methods>;
}

Answer 1

您应该删除或优化该选项-keepattributes。这意味着使用局部变量名称保留属性：

-keepattributes LocalVariableTable,LocalVariableTypeTable

您至少可以排除那些

-keepattributes !LocalVariableTable,!LocalVariableTypeTable

理想情况下，您只保留严格要求的属性。

请参阅ProGuard手册>用法>
-keepattributes
