Abstract:
Embodiments of the present invention provide various communication techniques for communication between a mobile computing device and an accessory. An accessory protocol that is generic to the mobile computing device can be used for some communication. An application executing at the mobile computing device can communicate with the accessory using an application communication protocol. In some embodiments, the application communication protocol can be different from the accessory communication protocol. In other embodiments the application protocol may only be recognized by the application and the accessory. In some embodiments, messages conforming to an application protocol can be communicated between the application and the accessory by packaging the messages inside a message conforming to the accessory communication protocol.
Abstract:
A routing screen (1705) is presented on an electronic device by a user interface application in response to receiving a notification that an external audio device is connected to the electronic device. The routing screen displays representations of an internal audio device (1721, 1723) and the external audio device (1719). In one aspect,. the representations are buttons. In another aspect, the representations are entries in a list. If a user selects one of representations, the user interface application causes the audio signals' to be routed to the audio device represented by the selection. An application control screen having a se£ of objects that represent functions for an audio application may also be.displayed. One of the objects on the application control screen is modified in response status changes in the external audio device. A user may select this object to access the routing screen when the external audio device is connected.
Abstract:
Systems, methods and machine (e.g. computer) readable media for providing or managing or using voicemails are described. In one embodiment, a method includes receiving at least notifications of voicemails at a mobile data processing system and storing a data structure at the mobile data processing system for deleted voicemails. In another embodiment, a method includes determining an extent of usage of a voicemail mailbox at a data processing system and determining a period of time representing how long a voicemail has been marked as deleted and determining, based on the extent of usage and based on the period of time, whether to delete the voicemail.
