Hi Shyam,
This is Mark, let me support you on this as Teejay's out of the office today.
Binding ad elements may differ for different ad networks. You may refer to this sample implementation for third party adapters. In addition, you may utilize UnifiedNativeAdMapper to provide a mapping from the mediated ad network's native ad object. Also, with regard to getMediationAdapterClassName (), you can call this method inside OnUnifiedNativeAdLoadedListener or you can create your own callback implementations using AdListener.
