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.

Claims

1. A method, comprising:

receiving, by a first messaging application (app) on a first device, a message and metadata from a second device, the message including content created by a second extension app that operated with a second messaging app on the second device;

displaying the content in a message container within a message transcript in the first messaging app;

receiving a selection of the message container;

launching a first extension app, if it is installed on the first device, in response to the selection, the first extension app being identified for launching by an app identifier in the metadata, wherein the first extension app is configured to be executed exclusively by the first messaging app and the first extension app is unexecutable by applications outside of the first messaging app; and

displaying, after the launching, a user interface of the first extension app within the user interface of the first messaging app.

2. The method as in claim 1 wherein the message container is a message bubble that is specified by a bubble identifier in the metadata, and the content is associated with the bubble identifier.

3. The method as in claim 2 wherein the first and the second messaging apps are each configured to transmit Short Message Service (SMS) text messages and other content and display the text messages in message bubbles in the message transcript and another message transcript.

4. The method as in claim 3 wherein the first messaging app and the first extension app are configured to communicate through interprocess communication (IPC), and the first messaging app executes in a first sandboxed process and the first extension app executes in a second sandboxed process that is distinct from the first sandboxed process.

5. The method as in claim 4 wherein the user interface of the first extension app replaces an on-screen keyboard of the first messaging app after the first extension app is launched.

6. The method as in claim 5 wherein the content is displayed by the first messaging app before the selection without launching or executing the first extension app.

7. The method as in claim 6 wherein an Application Program Interface (API) exists between the first messaging app and the first extension app, wherein the content is received in an encrypted form and is decrypted by the first messaging app and the decrypted form is passed, through an IPC, to the first extension app.

8. The method as in claim 7 wherein the first messaging app offers to download and install the first extension app if the first extension app is not installed.

9. The method as in claim 1 wherein the first extension app modifies the content and passes the modified content to the first messaging app, through an IPC, for transmission to the second messaging app for delivery to the second extension app on the second device, and wherein the first extension app receives a call back from the first messaging app which indicates whether the transmission was successful.

10. The method as in claim 1 wherein the first extension app receives an obfuscated identifier of the user of the second device, the obfuscated identifier being unique to the first extension app relative to other extension apps on the first device.

11. The method as in claim 1 wherein the first extension app is configured to process the content created by the second extension app, and wherein the second extension app and the first extension app are each identified by the same app identifier.

12. The method as in claim 1 wherein the first extension app calls, through an Application Program Interface (API), to the first messaging app to request a change of the extension app'"'"'s view within the first messaging app, and wherein the first extension app calls for at least one change of (a) a switch from a compact view, that replaces an on-screen keyboard of the messaging app, to an expanded view;

or (b) a switch from the expanded view to the compact view;

or (c) dismissal of the extension app'"'"'s view, and wherein the message transcript of the first messaging app is viewable when the compact view of the first extension app is displayed.

13. A device, comprising:

at least one processor; and

a memory including instructions that, when executed by the at least one processor, cause the at least one processor to;

receive, by a first messaging application (app) on a first device, a message and associated metadata from a second device, the message including content created by a second extension app that operated with a second messaging app on the second device, the first and the second messaging apps are each configured to transmit Short Message Service (SMS) text messages and other content and display the text messages in a message transcript;

display the content in a message transcript in a user interface view of the first messaging app;

communicate the content to a first extension app, identified by an app identifier in the metadata, from the first messaging app, the content communicated through an interprocess communication (IPC) from the first messaging app, which executes in a first process, to the first extension app, which executes in a second process that is distinct from the first process, wherein the first extension app is configured to be executed exclusively by the first messaging app and the first extension app is unexecutable by applications outside of the first messaging app; and

display a user interface of the first extension app within the user interface of the first messaging app.

14. The device as in claim 13 wherein the user interface of the first extension app is configured to display the content and to receive user input to modify the content and wherein the user interface of the first extension app, when displayed, replaces an on-screen keyboard of the first messaging app, and wherein the first extension app modifies the content and passes the modified content to the first messaging app, through an IPC, for transmission to the second messaging app for delivery to the second extension app on the second device.

15. The device as in claim 14 wherein the first extension app is configured to process the content created by the second extension app, and wherein the second extension app and the first extension app are each identified by the same app identifier and are two instances of the same extension app.

16. The device as in claim 13 wherein the metadata includes a resource locator and data which are communicated by the first messaging app to the first extension app through an IPC, and wherein the resource locator and data maintain session information between the second extension app and the first extension app that communicates with the second extension app through the second messaging app.

17. The device as in claim 16 wherein the first extension app is configured to modify at least one of the resource locator or data and pass the modified resource locator or data to the second extension app through the first messaging app and then the second messaging app, and wherein a same session bubble in the message transcript displays content for the session maintained by the modified resource locator or data, and wherein the first extension app receives a call back from the first messaging app which indicates whether the second extension app received the modified resource locator or data.

18. The device as in claim 13 wherein the first extension app receives an obfuscated identifier of the user of the second device, the obfuscated identifier being unique to the first extension app relative to other extension apps on the first device.

19. The device as in claim 13 wherein the first messaging app hosts views from multiple extension apps including the first extension app and a third extension app, each of the multiple extension apps having created content for at least one message bubble in the message transcript.

20. A non-transitory machine readable medium storing executable program instructions which when executed by a data processing system cause the data processing system to perform a method comprising:

creating, by an extension app executing in a first process, content displayed within a view hosted by a first messaging app on a first device, the first messaging app executing in a second process that is distinct from the first process, the content communicated from the extension app to the first messaging app through an interprocess communication in response to a selection of a command to cause the content to be sent to a second device, wherein the extension app is configured to be executed exclusively by the first messaging app and the extension app is unexecutable by applications outside of the first messaging app;

determining, by the first messaging app, from data about the second device, that a second messaging app on the second device is not compatible with the extension app; and

sending, by the first messaging app, alternative content to the second messaging app.
