Abstract

Multiple devices having different architecture or platforms may be supported by the same application store. The related devices are used to synchronize the state of each device in a group, such as all the devices owned or used by a particular user. The devices themselves are used as separate payload delivery systems that are capable of sharing software, such as new or updated applications and operating systems, among the different types of devices in the group. A software payload may be created by a server that contains software for more than one device'"'"'s architecture. They payload may include segments targeted for different platforms or architectures. Once the payload is loaded on one device, that device can then send the payload to the other devices within the group. Each device that receives the payload uses the appropriate software segment for its particular architecture or platform.

Claims

1. A first device, comprising:

a network interface configured to establish a network connection between the first device and a second device, wherein the first device comprises a first execution platform, and wherein the second device comprises a second execution platform;

a persistent memory configured to store a header and one or more payloads received from a server over the network interface, the one or more payloads containing application code for devices of the first platform, application code for devices of a second platform, and common code for devices of the first platform and devices of the second platform, wherein the common code is distinct from the header and includes executable binary code loadable as a runtime application, wherein the first device is capable of executing the runtime application but cannot install the runtime application on itself; and

a processor coupled to the network interface and to the persistent memory, the processor configured to execute instructions that cause the first device to;

receive the one or more payloads;

store the one or more payloads to the persistent memory;

transmit at least a part of the application code for the devices of the second platform and at least part of the common code to the second device based at least in part upon the detection of the network connection to the second device, wherein the second device can install the runtime application on itself; and

update a device state table to indicate the second device has an installed state corresponding to the transmitted code, wherein the device state table tracks installation of application code from the one or more payloads.

2. The first device of claim 1, wherein each of the one or more payloads is divided into a plurality of segments, wherein a first segment contains application code for devices of the first platform, and wherein a second segment contains application code for devices of the second platform.

3. The first device of claim 1, wherein a first payload of the one or more payloads contains application code for devices of the first platform, and wherein a second payload of the one or more payloads contains application code for devices of the second platform.

4. The first device of claim 1, wherein the processor is further configured to execute instructions that cause the first device to:

send a notification message indicating that application code from the one or more payloads was installed on the first device.

5. The first device of claim 4, wherein the processor is further configured to execute instructions that cause the first device to:

send a notification message indicating that application code from the one or more payloads was provided to the second device.

6. The first device of claim 1, wherein the processor is further configured to execute instructions that cause the first device to:

delete the application code installed on the first device from the persistent memory.

7. The first device of claim 1, wherein the processor is further configured to execute instructions that cause the first device to:

delete the application code transmitted to the second device from the persistent memory.

8. A method for distributing application code from a first device, the method comprising:

receiving, from a server over a network, a header and one or more payloads containing application code for devices of a first platform type, application code for devices of a second platform type, and common code for devices of the first platform type and devices of the second platform type, wherein the common code is distinct from the header and includes executable binary code loadable as a runtime application, and wherein the first device is capable of executing the runtime application but cannot install the runtime application on itself;

storing the one or more payloads to a persistent memory;

establishing a network connection between the first device and a second device, wherein the second device is of the second platform type;

transmitting at least a part of the application code for devices of the second platform type, and at least part of the common code to the second device, wherein the second device can install the runtime application on itself; and

updating a device state table to indicate the second device has an installed state corresponding to the transmitted code, wherein the device state table tracks installation of application code from the one or more payloads.

9. The method of claim 8, wherein each of the one or more payloads is divided into a plurality of segments, wherein a first segment contains application code for devices of the first platform type, and wherein a second segment contains application code for devices of the second platform type.

10. The method of claim 8, wherein a first payload of the one or more payloads contains application code for devices of the first platform type, and wherein a second payload of the one or more payloads contains application code for devices of the second platform type.

11. The method of claim 8, further comprising:

sending a notification message indicating that application code from the one or more payloads was installed on the first device.

12. The method of claim 11, further comprising:

sending a notification message indicating that application code from the one or more payloads was provided to the second device.

13. The method of claim 8, further comprising:

deleting the application code installed on the first device from the persistent memory.

14. The method of claim 8, further comprising:

deleting the application code transmitted to the second device from the persistent memory.

15. The method of claim 8, further comprising:

tracking every transmittal of the application code from the one or more payloads.
