I know many guys have asked a similar question but still, I can’t find what has caused this.
My Android application uses 3 differents Twitter account for different locale with twitter4j library. Two of them works perfectly (they were created more than 2 years ago) and the third (also the newer) always give me a 401 with the error:
08-08 12:22:39.405: W/System.err(4750): oauth.signpost.exception.OAuthNotAuthorizedException: Authorization failed (server replied with a 401). This can happen if the consumer key was not correct or the signatures did not match.
Of course I double-checked the consumer Key, the consumer Secret and it can’t be a date problem since it works with other account.
Do you have ideas?
Is it possible that a change in Twitter security policy has not been replicated to the older account?
