android Proguard 混淆与 twitter4j

Question

我正在尝试将 proguard 与 twitter4j 一起使用，并在调用 new TwitterFactory(configuration) 时不断收到 noMethodFound 异常。这是一个例外：

在我的 proguard 配置中（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 没有同时使用 Configuration 和 Authorization 对象作为参数的构造函数。我不知道它为什么要寻找这样的方法......

请帮忙？

Answer 1

我对 Twitter 4j 的 proguard 配置如下：-

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

我也在使用compile 'org.twitter4j:twitter4j-core:4.0.2'

让我知道它是否适合你。
