DrmSessionEventListener

default void onDrmKeysLoaded(
    int windowIndex,
    @Nullable MediaSource.MediaPeriodId mediaPeriodId
)

Called each time keys are loaded.

default void onDrmKeysRemoved(
    int windowIndex,
    @Nullable MediaSource.MediaPeriodId mediaPeriodId
)

Called each time offline keys are removed.

default void onDrmKeysRestored(
    int windowIndex,
    @Nullable MediaSource.MediaPeriodId mediaPeriodId
)

Called each time offline keys are restored.

default void onDrmSessionAcquired(
    int windowIndex,
    @Nullable MediaSource.MediaPeriodId mediaPeriodId
)

default void onDrmSessionAcquired(
    int windowIndex,
    @Nullable MediaSource.MediaPeriodId mediaPeriodId,
    @DrmSession.State int state
)

Called each time a drm session is acquired.

default void onDrmSessionManagerError(
    int windowIndex,
    @Nullable MediaSource.MediaPeriodId mediaPeriodId,
    Exception error
)

Called when a drm error occurs.

This method being called does not indicate that playback has failed, or that it will fail. The player may be able to recover from the error and continue. Hence applications should not implement this method to display a user visible error or initiate an application level retry (onPlayerError is the appropriate place to implement such behavior). This method is called to provide the application with an opportunity to log the error if it wishes to do so.

default void onDrmSessionReleased(
    int windowIndex,
    @Nullable MediaSource.MediaPeriodId mediaPeriodId
)

Called each time a drm session is released.
