There is a bug in the way notification client list is managed when the client binder interface dies that makes that the dead client is not removed from the list: the week reference passed by binderDied() cannot be promoted and compared to the strong references in the list. The fix consists in creating a new NotificationClient class that implements the binder DeathRecipient and holds a strong reference to the IAudioFlingerClient interface. A new instance of this class is created for each cient and a strong reference to this object is added to the notification client list maintained by AudioFlinger. When binderDied() is called on this object, it is removed from the list preventing AudioFlinger to notify this client for further io changes. Also added code to disable LifeVibes effects when the client that has enabled the enhancements dies. Change-Id: Icedc4af171759e9ae9a575d82d44784b4e8267e8
