Could not find class 'twitter4j.http.AccessToken'
I use twitter4j library to make somethings with twitter. But i have a problem about AccesToken class. I checked my libraries, there is only one AccesToken class and it is in twitter4j.http There are no other AccesToken class. My code was working about 10 hours ago, but now it doesn't work. I am about to go mad :/ Here is my log trace: 04-24 15:53:32.767: E/dalvikvm(305): Could not find class 'twitter4j.http.AccessToken', referenced from method com.twitterresim.TwitterOnay.isAuthenticated 04-24 15:53:32.767: W/dalvikvm(305): VFY: unable to resolve new-instance 67 (Ltwitter4j/http/AccessToken;)
