When I enabing proguard for android, the proguard will obfuscate all the jars that include in the application. These jars include:

  • libraryjars lib/Analytics_Android_SDK_2.1.jar
  • libraryjars lib/commons-codec.jar
  • libraryjars lib/commons-httpclient-3.1.jar
  • libraryjars lib/commons-logging-1.1.jar
  • libraryjars lib/weibo.jar
  • libraryjars lib/signpost-core-1.2.1.1.jar
  • libraryjars lib/signpost-commonshttp4-1.2.1.1.jar
  • libraryjars lib/youmibannerad-android.jar

while building the signed jar I get the following dump:

    06-25 16:07:25.094: WARN/dalvikvm(13785): Exception Ljava/lang/NoSuchMethodError; own   while initializing Lorg/apache/commons/httpclient/HttpMethodBase;

In fact this project is about sina weibo SDK, when I use proguard to obfuscate it, I always fail, with the error below:

so I added the code -ignorewarnings into proguard config file, so the warnings all dismissed, but when I run the application, The errors that in the title will happened.

在一个外包项目中遇到了同样的问题，似乎开发人员已经使用了世界上所有可能的免费库。

最安全的方法是为 ProGuard 提供原始库作为参考，即使其中一些已被弃用并且可能永远不会被您的代码调用：

Log4J - http://logging.apache.org/log4j/1.2/download.html

阿瓦隆 - http://www.docjar.com/jar_detail/avalon-framework-4.2.0.jar.html

Avalon LogKit - http://www.jarfinder.com/index.php/jars/versionInfo/17610

J2EE 参考 - http://www.jarfinder.com/index.php/jars/versionInfo/4598

下载所有 jar 包后，将 ProGuard 指向它们：

# Apache commomns-logging fun

-libraryjars proguard_ref_lib/log4j-1.2.17.jar
-libraryjars proguard_ref_lib/avalon-framework-4.2.0.jar
-libraryjars proguard_ref_lib/avalon-logkit-2.2.1.jar
-libraryjars proguard_ref_lib/servlet-api-6.0.16.jar

# Apache commomns-logging fun ends

我会尝试 commons-logging-1.1.1。好像版本不匹配
