Getting HTTP failed Status 403

fabric
oauth

#1

I have integrated twitter fabric and I’m able to connect with twitter, authenticate user, get authorizatoin token but when I post a tweet it fails.
Error says :

" Post Tweet failed

com.twitter.sdk.android.core.TwitterApiException: HTTP request failed, Status: 403

What could be its reason.? I want to use card. My work will also be done if we can set some pre-text in tweet box. Please help
