4. The computer-implemented method of claim 1, comprising triggering an operating system to install the second application.

5. The computer-implemented method of claim 1, comprising determining whether the second application is installed.

6. The computer-implemented method of claim 5, comprising, following the determination whether the second application is installed, determining whether a timeout period has elapsed.

7. The computer-implemented method of claim 1 21, wherein the deep link uses a custom uniform resource locator (URL) protocol registered to the second application that describes a specific action to perform or content to display using the second application.

8. A non-transitory, computer-readable medium storing computer-readable instructions for providing contextual ecommerce shopping cart adjustments, the instructions executable by a computer and comprising: receiving, by a first user application executing on a mobile computing device, an indication on a mobile computing device of an expressed intent to perform an action not available in a the first application executing on the mobile computing device; requesting, by the first application, a list of one or more applications capable of fulfilling the action from a contextual application determination Service, wherein the request to the contextual application determination Service includes available contextual data, and wherein the contextual application determination Service is remote from the mobile computing device; receiving, by the first application, a policy and a list of applications that can fulfill the action;, wherein the policy instructs the first user application to either favor applications on the list of applications that are or are not installed; selecting, by the first application, a second application from the list of applications to perform the action based on the policy; transmitting, by the first user application, a query to an operating system of the mobile computing device to determine if the second application is installed on the mobile computing device; receiving, by the first application, a response from a to the transmitted query, to an operating system of the mobile computing device to determine if the second application is installed on the mobile computing device, wherein the response indicates indicating whether the second application is installed; and installing the second application on the mobile computing device if in response to determining the second application is not installed; and. executing a deep link into the second application so that the second application can automatically perform the action.

9. The non-transitory, computer-readable medium of claim 8, wherein the received list of applications that can fulfill the action is prioritized.

10. The non-transitory, computer-readable medium of claim 8, comprising one or more instructions to enumerate the list of applications that can fulfill the action.

11. The non-transitory, computer-readable medium of claim 8, comprising one or more instructions to trigger an operating system to install the second application.

12. The non-transitory, computer-readable medium of claim 8, comprising one or more instructions to determine whether the second application is installed.

13. The non-transitory, computer-readable medium of claim 12, comprising one or more instructions to, following the determination whether the second application is installed, determine whether a timeout period has elapsed.

14. The non-transitory, computer-readable medium of claim 8 22, wherein the deep link uses a custom uniform resource locator (URL) protocol registered to the second application that describes a specific action to perform or content to display using the second application.

15. A system, comprising: a hardware processor interoperably coupled with a computer memory and configured to: receive, by a first user application executing on the hardware processor, an indication on a mobile computing device of an expressed intent to perform an action not available in a the first application executing on the mobile computing device; request, by the first user application, a list of one or more applications capable of fulfilling the action from a contextual application determination Service, wherein the request to the contextual application determination Service includes available contextual data, and wherein the contextual application determination Service is remote from the mobile computing device; receive, by the first application, a policy and a list of applications that can fulfill the action, wherein the policy instructs the first user application to either favor applications on the list of applications that are or are not installed; select, by the first application, a second application from the list of applications to perform the action based on the policy; transmit, by the first user appication, a query to an operating system of the mobile computing device to determine if the second application is installed on the mobile computing device; receive, by the first user application, a response from a to the transmitted query, to an operating system of the mobile computing device to determine if the second application is installed on the mobile computing device, wherein the response indicates indicating whether the second application is installed; and install the second application on the mobile computing device if in response to determining the second application is not installed; and. execute a deep link into the second application so that the second application can automatically perform the action.

16. The system of claim 15, wherein the received list of applications that can fulfill the action is prioritized.

17. The system of claim 15, further configured to enumerate the list of applications that can fulfill the action.

18. The system of claim 15, further configured to: trigger an operating system to install the second application; and determine whether the second application is installed.

19. The system of claim 18, further configured to, following the determination whether the second application is installed, determine whether a timeout period has elapsed.

20. The system of claim 15, wherein the deep link uses a custom uniform resource locator (URL) protocol registered to the second application that describes a specific action to perform or content to display using the second application.

21. The computer-implemented method of claim 1, further comprising executing a deep link into the second application so that the second application can perform the action.

22. The non-transitory, computer-readable medium of claim 8, comprising one or more instructions to execute a deep link into the second application so that the second application can perform the action.
