<Edited by bwfcwalshy: Fixed missing "s.>

 

@XxZHALO13Xx According to said stack trace, it's having trouble loading https://mobile.twitter.com/login.

 

@DJSkepter idk how to fix it tho

 

@XxZHALO13Xx Oracle - "Signals that an unexpected exception has occurred in a static initializer". http://docs.oracle.com/javase/7/docs/api/java/lang/ExceptionInInitializerError.html I'm still new to Java but I am thinking its the twitter object. What is the getTwitter() methods code?
