【问题描述】：

我在创建我的应用程序的签名 apk 时收到此异常。我使用了两个外部库。我是 Proguard 的新手。请帮忙！这是我的配置文件：

    -dontwarn android.support.**
    -dontwarn aspose-cells-2.0.0.**
    -injars       mylibs/aspose-cells-2.0.0.jar
    -outjars      out.jar
    -libraryjars  <java.home>/lib/rt.jar
    -printmapping out.map

    -keepparameternames
    -renamesourcefileattribute SourceFile
    -keepattributes Exceptions,InnerClasses,Signature,Deprecated,
            SourceFile,LineNumberTable,*Annotation*,EnclosingMethod

    -keep public class * {
        public protected *;
    }

    -keepclassmembernames class * {
        java.lang.Class class$(java.lang.String);
        java.lang.Class class$(java.lang.String, boolean);
    }

    -keepclasseswithmembernames class * {
        native <methods>;
    }     

    -keepclassmembers enum * {
        public static **[] values();
        public static ** valueOf(java.lang.String);
    }

    -keepclassmembers class * implements java.io.Serializable {
        static final long serialVersionUID;
        private static final java.io.ObjectStreamField[] serialPersistentFields;
        private void writeObject(java.io.ObjectOutputStream);
        private void readObject(java.io.ObjectInputStream);
        java.lang.Object writeReplace();
        java.lang.Object readResolve();
    }

这是控制台中的异常：

    Proguard returned with error code 1. See console

【解决方案1】：

据我了解，您要求它保留方法，而不是类。

试试类似的东西

-keep public class com.ggg.xxx.Yyy { *; }

-keep public class mypackage.MyActivity
