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 text messaging system that allows messaging apps to send one or more layer identifiers that can specify content for a layer and Z depth of that layer relative to other layers in a text message transcript such as a sent message layer and a received message layer.

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: A device provides user interfaces for a messaging application. The device receives a first message and displays a representation of the first message, where the first message is scheduled to be deleted upon satisfaction of expiration criteria. The device displays an affordance for keeping the first message. In accordance with a determination that the affordance was selected prior to the satisfaction of the expiration criteria, the device keeps the first message. In accordance with a determination that the expiration criteria has been satisfied without detecting selection of the affordance, the device ceases to display the representation of the first message on the display.

Abstract: A messaging system in one embodiment includes a messaging app and one or more extension apps configured to create content that is displayed in a view hosted by the messaging app. The messaging app can launch the one or more extension apps, and content can be communicated between each extension app and the messaging app through an interprocess communication.
