Attributes

Remarks

The keys in an offline license allow protected content to be played even if the device is not connected to a network. Offline licenses are stored on the device after a key request/response exchange when the key request KeyType is OFFLINE. Normally each app is responsible for keeping track of the keySetIds it has created. If an app loses the keySetId for any stored licenses that it created, however, it must be able to recover the stored keySetIds so those licenses can be removed when they expire or when the app is uninstalled.

This method returns a list of the keySetIds for all offline licenses. The offline license keySetId may be used to query the status of an offline license with #getOfflineLicenseState or remove it with #removeOfflineLicense.
