Я хочу использовать Proguard в основном для запутывания.

У меня проблема с proguard в Android. Я использовал simpleframework для разбора XML; его внешний.

В Proguard CFG:

    -keepattributes *Annotation*,EnclosingMethod    
    -keep public class org.simpleframework.**{ *; }
    -keep public class org.simpleframework.xml.**{ *; }
    -keep public class org.simpleframework.xml.core.**{ *; }
    -keep public class org.simpleframework.xml.util.**{ *; }
    -keep public class org.simpleframework.xml.stream.**{ *; }
    -keep public class javax.** { *; }
    -keep public class javax.xml.stream.**{ *; }

    -keep public class org.simpleframework.** {
      public void set*(***);
      public *** get*();
    }

ошибка:

Я понятия не имею, как решить эту проблему. Путь к Gradle CFG в порядке.

в градле:

    buildTypes {
        release  {
            runProguard true
            proguardFile file('proguard.txt')
            signingConfig signingConfigs.release
        }
    }
