OTVNetworkStatisticsListener errors

The OTVNetworkStatisticsListener provides HTTP errors that occur during playback. The errorCode corresponds to the HTTP error code, and the errorMessage is a short description of the code. Although only a few errors are listed here, the OTVNetworkStatisticsListener provides all invalid HTTP response codes.

Register a callback with OTVNetworkStatistics to handle network statistics errors. 

/**
  *  Register a callback with OTVNetworkStatistics
  */
public void setNetworkStatisticsListener(OTVNetworkStatisticsListener listener);

OTVNetworkStatisticsListener needs to be implemented by application while registering.
