Ya! I did go through these articles and blog but in my case there is conflict on 1st revision itself and one of the 1st revision is made by android (found in changes.getSource()) and second 1st revision has source sync gateway with exact same data (came after 3-6 sec of 2nd revision). Couchbase server is not handling changes, so connection is with android and syncgateway only. This situation occurs 50:50 ratio.
