Android IDs (GAID): Use ID 20914 in a data file name if it contains Android IDs. You need to use the field _DPID_TARGET_DATA_OWNER when you use Android IDs. For example,...ftp_dpm_20914_DPID_TARGET_DATA_OWNER_123456789.sync tells Audience Manager that the data file contains Android IDs only and the IDs should qualify for the traits belonging to the _DPID_TARGET_DATA_OWNER data source.
