5. The method of claim 1, wherein performing content discovery further comprises:

responsive to receiving, by the second computing device, a content discovery query message, transmitting, by the second computing device to the first computing device, a content discovery response message, wherein the content discovery response message includes content information for at least one content item described in the content discovery query message.

6. The method of claim 1, wherein performing content discovery comprises:

transmitting, by the second computing device to the first computing device, the content information associated with the content item accessible to second computing device, wherein the content information associated with the content item comprises at least one of a group consisting of;

a filename, a file extension, a file size, a duration, a file protection, and a file category.

7. The method of claim 1, wherein the first computing device is a head unit of an infotainment system.

8. The method of claim 7, wherein performing content discovery further comprises:

receiving, by the head unit, content information associated with the content item accessible to the second computing device, from the second computing device; and

receiving, by the head unit, content information associated with a content item accessible to a third computing device from the third computing device.

9. The method of claim 8, further comprising:

receiving, by the head unit, a user input selection of either the second computing device or the third computing device; and

responsive to receiving the selection, establishing the session of the service with the selected second computing device or third computing device.

10. The method of claim 1, wherein performing the content discovery comprises performing the content discovery at a layer 2 (L2) open systems interconnection (OSI) model level.

11. A first computing device comprising:

a memory storing instructions; and

at least one processor, wherein the at least one processor is configured to;

establish a connection with a second computing device;

perform service discovery with the second computing device;

perform content discovery with the second computing device before performing device association, wherein to perform content discovery, the at least one processor is configured to receive, from the second computing device, content information associated with a content item accessible to the second computing device, wherein the content item includes a file, an audio file, or a video file; and

establish a session of a service after performing content discovery.

12. The first computing device of claim 11, wherein to perform content discovery, the at least one processor is configured to transmit content information associated with a content item accessible to the first computing device.

13. The first computing device of claim 11, wherein the connection is a wireless connection, and wherein the connection is established the using Wi-Fi Direct (WFD).

14. The first computing device of claim 11, wherein to perform content discovery, the at least one processor is further configured to transmit a content discovery query message, wherein the content discovery query message includes at least one type length value (TLV) that describes at least one property of at least one content item.

15. The first computing device of claim 11, wherein the content information associated with the content item comprises at least one of a group consisting of:
