Re: [twitter-dev] Problems with Twitter4J and OAuth on Android
Hi Clay,
Just noticed that you have an API secret in this code sample you've
provided -- you'll want to go to your application record and
regenerate a new key/secret pair.
As for the code itself -- I see you setting your consumer key and
secret as constants near the top, but then in askOAuth you're using
different values -- is this just a result of a bad paste?

[twitter-dev] Problems with Twitter4J and OAuth on Android
Cant figure out if this is a problem with Twitter4J or the Twitter
API. I am trying to create an OAuth callback activity, started by a
RequestToken, but the Request Token request is failing. DOES ANYONE
KNOW IF GOOGLE HAS MADE THE TWITTER CLIENT AVAILABLE BY OPEN SOURCE
YET?
