我的proguard.cfg文件看起来像,

-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keepclasseswithmembers class * {

}

-keepclassmembers class * extends android.app.Activity {

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

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

谁可以帮我这个事？我需要发布我的应用程序.该解决方案将不胜感激.提前致谢.

Answer 1

如果不需要缺少的类,则可以禁止显示警告:

-dontwarn org.joda.convert.**

请参阅ProGuard手册>故障排除> 警告:找不到引用的类

Answer 2

根据此处的帖子:https://plus.google.com/112998433182673852267/posts/ApBBBjv9szw

实际发生的是缺少的"FromString"类是一个注释,它实际上并不作为joda-time-2.0.jar中的类文件存在.有一个声明(http://www.scala-lang.org/node/10575),一个缺失的注释类文件不应该影响编译,这听起来是正确的,但我不知道这是正式声明的位置.

您需要将http://joda-convert.sourceforge.net/添加到项目的构建路径中.
