与twitter4j的android Proguard混淆

我试图在twitter4j上使用proguard,并在调用新的TwitterFactory(配置)时不断收到noMethodFound异常.这是例外：

java.lang.AssertionError: java.lang.NoSuchMethodException: <init> [interface twitter4j.conf.Configuration,interface twitter4j.auth.Authorization]

在我的proguard配置(与twitter相关)是：

-dontoptimize
    -dontpreverify
    -dontobfuscate

    -optimizations !code/simplification/arithmetic
    -allowaccessmodification
    -repackageclasses ''
    -keepattributes *Annotation*
    -keepattributes InnerClasses
    -keepattributes Signature
    -keepattributes Exceptions
    -keepattributes JavascripTinterface
    -dontnote
    -dontwarn twitter4j.**
    -keep class twitter4j.**
    -keep public class twitter4j.TwitterFactory
    -keep interface twitter4j.**

问题是,TwitterFactory没有使用COnfiguration和Authorization对象作为参数的构造函数.我不知道为什么要寻找这样的方法……

请帮忙？

-dontwarn twitter4j.**
-keep  class twitter4j.conf.PropertyConfigurationFactory
-keep class twitter4j.** { *; }
