android simple facebook returns "Canceled by user" when publishing post

Question

I have configured android simple facebook library for my app. It's working properly, but the problem is when using mSimpleFacebook.publish(feed, true, onPublishListener), it always fails with error "canceled by user".

Permission[] permissions = new Permission[] {
   Permission.EMAIL,
   Permission.PUBLIC_PROFILE,
   Permission.PUBLISH_ACTION
};

Any idea what the problem might be?

Thanks
