Abstract: A messaging system includes a first messaging app on a first device and a second messaging app, on a second device, that can exchange messages (e.g. text messages, etc.), and the second messaging on can transmit content from a second extension app that operates with the second messaging app to the first messaging app that operates with a first extension app. The content can be opaque to the messaging app, but can be processed by the extension apps to display live, dynamic content in message bubbles in a message transcript of a conversation.

Abstract: A quick relay communication protocol is used by an initiating communication device (such as a wearable electronic device, e.g., a smart watch) and/or a recipient communication device (such as a companion electronic device to the wearable electronic device, e.g., a smart phone, a tablet computer or a laptop computer) to selectively communicate messages via different communication channels. Based on available connections and a communication constraint associated with a message, a processor executing a program module in an application layer in the initiating communication device provides transmission instructions to an interface circuit in the initiating communication device, which transmits a message to the recipient communication device based on the transmission instructions.

Abstract: Systems, methods and non-transitory computer readable media for allowing a user to switch between wearable items that have been paired or associated with an electronic device, such as a smartphone, are described. In one embodiment, the wearable items automatically detect a removal of a first wearable item from a user's body and an attachment of a second wearable item to the user's body. Messages from the wearable items are transmitted to the electronic device to allow the electronic device to switch the active wearable item from the first wearable item to the second wearable item. The switch can occur while the electronic device is in a locked state, and the electronic device can synchronize the second wearable item with data received from the first wearable item. Other embodiments are also described.

Abstract: A device implementing a system for sharing groups of files within a messaging application includes a processor configured to provide, within the messaging application, a user interface element for sending at least one file to a participant in an active message thread of the messaging application, the at least one file having been determined to be relevant to the participant. The processor is further configured to, responsive to receiving a selection of the user interface element: transmit, to a server, a request to store the at least one file in association with a shared storage area, and to transmit, via the messaging application, a message to the participant in the active message thread, the message comprising information for accessing the at least one file associated with the shared storage area.

Abstract: Improved messaging applications are described that use a first set of software to test rendering of a message, and if the test is successful the message is allowed to be presented. In one embodiment, a first set of software can attempt to test the renderability of a message and if the test is successful, the message can be stored in a message database. In one embodiment, the first set of software operates in a separate sandbox from a sandbox for a messaging application which displays the message. The first set of software can operate in a first process which is different than a process in which the messaging application runs.

Abstract: Some embodiments relate to a device that transmits/receives encrypted communications with another device. A first device, such as a smart phone or smart watch, may generate a message associated with a certain data class, which may determine the security procedure used in the communication of the message. The first device may establish an encryption session for the purpose of communicating the message to a second device. Prior to sending the message, the first device may wait until encryption credentials are accessible according to certain conditions, which may be determined at least in part by the data class of the message. Similarly, after receiving the message, the second device may not be able to decrypt the message until encryption credentials are accessible according to certain conditions, which may be determined at least in part by the message data class.

Abstract: A system and method are described for establishing two-way communication between proxy devices that have a certain set of hardware and/or capabilities allowing the proxy devices to send and receive SMS/MMS messages using cellular networks on behalf of proxied devices that lack the hardware and/or capabilities. The proxy device can receive a message from a service provider. The message may be associated with information, and the proxy device can determine a recipient of the message based at least in part on the information. The proxy device can determine whether delivery of the message to the recipient is restricted and, if not, transmit the message the proxied device and/or the recipient.
