Failed to get request token on Android M running Devices

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 was facing the same issue(just moments back).

Go to Twitter Application Management ->
Click on the 'app' on which you are currently working ->
Click on 'Settings' tab ->
1) Callback URL: Insert any valid url(like homepage of your website)
2) Enable Callback Locking (It is recommended to enable callback locking to ensure apps cannot overwrite the callback url): Verify that it is unchecked

Twitter Kit tries to use a webview if the twitter app is not found.
The webview part of Twitter kit needs to override the callback url.

Info about Callback Url field clearly states: To restrict your application from using callbacks, leave this field blank.
So, we need to write down any valid url :)
