Question

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_ K

Answer 1

I had the same problem on iOS, and found a hint here:
Apparently, it is now required to set the Callback URL to

http://twitter-oauth.callback

Sind I did so, the login works again.
