Obfuscating Proguard androids with twitter4j
I am trying to use proguard with twitter4j and keep getting noMethodFound exception when called new TwitterFactory(configuration)
. This is an exception:
java.lang.AssertionError: java.lang.NoSuchMethodException: <init> [interface twitter4j.conf.Configuration, interface twitter4j.auth.Authorization]

In my proguard config (in relation to twitter) there is:
-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.**
The point is that there is no constructor for TwitterFactory that takes configuration and authorization objects as parameters. I have no idea why he is looking for a method like this ...
Help me please?
