Implementazione del supporto per metadati personalizzati

Puoi fornire metadati personalizzati su contenuti, annunci e chiamate di tracciamento dei capitoli utilizzando funzioni di callback.

Le funzioni di callback vengono richiamate immediatamente prima della chiamata di tracciamento, in modo che l’applicazione possa allegare i metadati specifici di un annuncio o di un capitolo.

1. Richiama le funzioni di callback per contenuto, annunci e capitoli.
