Question

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:

Answer 1

try renaming the “lib” folder name to “libs”. That solved the issue for me, check here:
