Twitter login failed in Android 6.0 preview devices. Its working fine on all other devices.
Below code is used to initialize fabric with twitter.
TWITTER_ KEY and TWITTER_SECRET keys were obtained from twitter app settings.
TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
Fabric.with(this, new Twitter(authConfig));
Here is the error log i got during login using TwitterApiClient.

Here are the things you need to do
Twitter dev account->setting->callBack url
and then if you are doing for the android (means login using for android devices )
twittersdk://
(add this in callback)
if you are doing for the iOS (means login using for apple devices )
twitterkit-CONSUMERKEY://
(add this in callback)
and hit update settings button it will work :)
