Android Proguard跳过外部jar

我试图在我的Android项目中使用Proguard，我使用命令行'android update project/path/to/project'设置Proguard，并在项目的根目录中创建了proguard.cfg文件。（在我的Eclipse中使用Android 2.3 sdk创建新项目时，proguard.cfg文件不会自动创建，因此我必须使用命令行手动添加它）。Android Proguard跳过外部jar

当我出口的项目，我得到了以下错误

这些错误消息指向我的项目中使用

以下四个外部罐是我的proguard.cfg文件

-optimizationpasses 5 
-dontusemixedcaseclassnames 
-dontskipnonpubliclibraryclasses 
-dontpreverify 
-verbose 
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

    public static ** valueOf(java.lang.String); 
} 

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

我加入“-libraryjars”选项，前试穿网上找到了一些解决方案：

-libraryjars /Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/twitter4j-core-2.1.6.jar

，但它不会帮助。

任何解决方案？

你的库jars引用更多的库jar（Mortbay，SLF4J，Apache Commons Logging，Log4j，...）添加这些jar与额外'-libraryjars'选项应该可以解决这个问题。

如果您确信您的代码不使用这些库，您可以指定'-ignorewarnings'或'-twtwarn'，例如

-dontwarn org.mortbay.** 
-dontwarn org.slf4j.** 
-dontwarn org.apache.log4j.** 
-dontwarn org.apache.commons.logging.** 
-dontwarn org.apache.commons.codec.binary.**

嗨埃里克，thanx的解决方案。我已经添加了-libraryjars到你已经指出的库：警告消息消失，但是当我运行应用程序强制关闭时，从日志消息我发现'classnotfound异常'在twitter4j –

尝试添加导致“ClassNotFoundException”到“保持”选项'-keep public class com.example.Foo {public protected *; }' –

你会在-libraryjars选项中使用什么路径？我似乎无法弄清楚。 – cottonBallPaws
