Methods and systems for a vehicle computing system to launch an application
A vehicle computing system includes at least one processor in communication with a mobile device via a wireless transceiver. The at least one processor is configured to launch a second application from an inactive state at the mobile device based on a message transmitted to a first application in an active state being executed in a foreground at the mobile device. The message is configured with an application identification of the second application.
1. A system comprising:
a processor of a vehicle computing system, in communication with a mobile device via a wireless transceiver, configured to:
track which one of a plurality of mobile device applications installed to the mobile device is in a foreground state; and
in response to receiving a user request to launch a specified one of the mobile device applications that is not in the foreground state, send a message to the mobile device application in the foreground state requesting launch of the specified mobile device application,
wherein the specified one of the mobile device applications that is not in the foreground state is an emergency application, and the mobile device application in the foreground state receiving the message requesting launch of the emergency application is not an emergency application.
2. The system of claim 1 , wherein the processor of the vehicle computing system is further configured to track which one of the mobile device applications is in the foreground state based on change-in-state notification messages received from the mobile device.
3. The system of claim 2 , wherein not being in the foreground state includes being in a background state or a closed state on the mobile device.
4. The system of claim 1 , wherein the processor is further configured to receive a change-in-state notification message from the mobile device responsive to the specified mobile device application moving from a closed state to the foreground state; and
responsive to receipt of the change-in-state notification message, update an indication of which one of the plurality of mobile device applications installed to the mobile device is in the foreground state.
5. The system of claim 1 , wherein the processor is further configured to:
receive a change-in-state notification message from the mobile device responsive to the mobile device application in the foreground state moving from the foreground state to a background state; and
responsive to receipt of the change-in-state notification message, update an indication of which one of the plurality of mobile device applications installed to the mobile device is in the foreground state.
6. The system of claim 1 , wherein the message requesting launch of the specified mobile device application includes a universal resource locator (URL) indicating an identifier of the specified mobile device application.
7. The system of claim 1 , wherein the processor is further configured to communicate with a user interface display and receive the user request from the user interface display.
8. The system of claim 7 , wherein the processor is further configured to output, to the user interface display, a first icon representing the one of the mobile device applications in the foreground state and a second icon representing the specified mobile device application, the first icon displayed in a state indicating the application being represented is in the foreground state, the second icon displayed in a state indicating the application being represented is not in the foreground state.
