如何使用ProGuard混淆android应用程序

我观看了，我的应用程序使用谷歌播放服务。我加了这句话

-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
    public static final *** NULL;
}

-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
    @com.google.android.gms.common.annotation.KeepName *;
}

-keepnames class * implements android.os.Parcelable {
    public static final ** CREATOR;
}

但当我导出应用程序时，会出现以下错误：

我刚开始使用proguard。我将发布我的第一个android应用程序。我不理解这些错误，所以有什么帮助吗？

可能是因为您在项目中使用了第三方库，而忘记使用“-libraryjars”标记将其包含在proguard.config中
