No errors showing but when the button is clicked, it always goes to callback the failure method.Internet is active and the keys are valid. I used debugger to see the following result:-
E/Twitter: Invalid json: <?xml version="1.0" encoding="UTF-8"?>
<hash>
<error>Desktop applications only support the oauth_callback value 'oob'</error>
<request>/oauth/request_token</request>
</hash>

I got the same error when the Twitter application was not installed on my device.
Desktop applications only support the oauth_callback value 'oob' /oauth/request_token
but when the Twitter application was installed on the device, then Twitter login worked correctly.
To get Twitter login to work if the Twitter application is not installed on a device, make the following changes to your app:
https://apps.twitter.com/app/13917465/permissions
Go to the "Permission" tab in your application, change Make Access to "Read, Write and Access direct messages" and also enable "Request email addresses from users" in "Additional Permissions".
Finally, save the changes by clicking on "Update Setting".
