Abstract

At least one embodiment of this disclosure includes a method of sharing application states across different user profiles. The method can include: receiving a request from a first computing device associated with a first user profile to load an application state of a target application, wherein the application state is owned by a second user profile; verifying permission for the first user profile to load the application state owned by the second user profile; configuring a sharing instance of the application state of the target application by accessing application data of the application state associated with the second user profile in a storage service; and sending the sharing instance to be loaded onto the first computing device.

RELATED FIELDS

At least one embodiment of this disclosure relates generally to cloud computing and, in particular, to mobile device based cloud computing.

BACKGROUND

Application state data is data used to record the running status of a computer application. One example of application state data is a “game save” for a game application. A game save is a piece of digitally-stored information about the progress of a user operating the game application. The game save can be reloaded later, so that the user can continue where he/she stopped. The user instructs the game application to generate a game save (i.e., save the game) to prevent the loss of progress in the game, especially when the user is interrupted or ending a game session.
Sharing game saves among users has been common for many years. Originally, by swapping memory cards with game saves, users could help each other to unlock features in a game application. With the growing popularity of the Internet, users can now upload their game saves from their devices to Internet servers. By downloading a game save from an Internet server, a user can continue the progress of the game on the device used to play the game or another device such as a computer, game console, or smart phone. However, to achieve the goal of continuing the progress on another device, the user needs to deliberately instruct the device to save the game progress (i.e., game save) and to upload the game save to a server or a memory card. Then the user needs to download the game from the server or the memory card to the other device and then instruct the other device to load the game save. The whole process is tedious and requires many user interventions. Furthermore, the process only works for game applications that are specifically designed with game saving functionalities.

DISCLOSURE OVERVIEW

Techniques introduced here provide an application state sharing mechanism between user profiles (e.g., implemented as separate user accounts). For example, different user profiles can lend application states to each other. In some embodiments, user profiles can share application states within the same computing device. In other embodiments, user profiles can share application states across multiple devices. The disclosed techniques can be implemented through a cloud computing system with multiple computing devices, each with a synchronization agent and an app-share agent. Through these agents and a cloud storage service, the cloud computing system can provide an application sharing platform for user profiles to share application states with each other.
For example, a first user can simply select a target application and a target user and, with a click of a button (e.g., a user interface generated by the app-share agent), load the most recent application state of the target application from the target user's devices. This application state sharing mechanism enables a user to conveniently load application states from other users. For example, this sharing mechanism can execute without the target user's manual retrieval of the application state and without having to iterate through multiple devices of the target user to identify the most recent application state at the time the application state request is made by the first user. In some embodiments, the first user can load the application state to his/her device without an explicit approval from the target user for the specific application state request.
The synchronization agent in a computing device can update application states with a cloud storage service (e.g., a centralized cloud service, a distributed cloud service, or a peer-to-peer cloud service). When to update can be determined either by the synchronization agent (e.g., by monitoring activity in the application) and/or by the cloud storage service (e.g., by monitoring requests for the application states). For example, the synchronization agent can determine to update when a pre-determined progress in the target application has been reached or when the target application is paused or has gone idled (e.g., from lack of user interaction). For another example, the cloud storage service can trigger an update of an application state when a request for the application state is made by another computing device. The cloud storage service can then distribute application states to the computing devices within the cloud computing system to ensure that the computing devices have consistent copies of applications managed by the cloud computing system.
For example, the synchronization agent can detect an instance of a computer application running at or at least installed on a first electronic device and determine an update event that occurs in the first electronic device. The update event is a process of making a copy of the execution status of the computer application. The application state data represents an application state of the computer application at the update event. The synchronization agent can then transmit the application state data of the computer application to the cloud storage service in response to the update event. Another electronic device can thus retrieve the application state data of the computer application from the cloud storage service and restore another instance of the computer application to the application state using the application state data. The update event can proceed automatically in the background of the operating system of the computing devices. The update event can be transparent to the user. The update event can also be transparent to the computer application.
The app-share agent in a computing device can facilitate a first user to load an application state of a target application from a second user. As discussed above, the loading of the application state can occur without interactions from the second user in response to a request to copy the application state associated with the second user. The app-share agent can send a request to the cloud storage service to retrieve the application state associated with a second user. The cloud storage service can match the request to application data associated with the most recent application state or whichever application state that is requested. The cloud storage service can then verify that the first user is permitted to load the application state to the computing device of the first user.
If the target application is not installed on the computing device, the app-share agent can first request to download the target application. The app-share agent can load the application state whether or not the target application expects the application state to be loaded. In some cases, the target application receives the application data from the app-share agent and provides at least part of the logic to load the application state. In other cases, the target application is paused or terminated such that the app-share agent can load the application data into operational memory portions of the target application.
In embodiments, the synchronization agent can back up a new application state of the target application on the computing device associated with the first user (e.g., the computing device that loaded a foreign application state) to the cloud storage service. In some embodiments, the cloud storage service can back up the new application state as a new set of application data independent of the original application data associated with the second user. In other embodiments, the cloud storage service can re-integrate the new application state to the original application data associated with the second user.
Some embodiments of this disclosure have other aspects, elements, features, and steps in addition to or in place of what is described above. These potential additions and replacements are described throughout the rest of the specification.

DETAILED DESCRIPTION

FIG. 1 is a block diagram of an example of a cloud computing system 100 for application state sharing between user profiles, in accordance with various embodiments. The cloud computing system 100 provides a state sharing platform to enable different user profiles to share application states. The cloud computing system 100 includes a cloud storage service 110 configured to store and manage application states and to load application states to different computing devices. In one embodiment, the cloud storage service 110 can be a device cluster having storage nodes 112 interconnected with each other by a storage network channel 118. The device cluster can communicate with other computing devices via a global network, such as the Internet, a local network, or a cloud data interface 120.
The cloud storage service 110 includes the storage nodes 112. Each of the storage nodes 112 includes one or more processors 114 and storage devices 116. The storage devices can include optical disk storage, RAM, ROM, EEPROM, flash memory, phase change memory, magnetic cassettes, magnetic tapes, magnetic disk storage, or any other computer storage medium which can be used to store the desired information.
The cloud storage service 110 can implement the cloud data interface 120 to receive data from and send data to computing devices (e.g., a first electronic device 130 and a second electronic device 140). The computing devices can include desktop computers, laptop computers, tablet computers, automobile computers, game consoles, smart phones, personal digital assistants, other computing devices capable of running computer applications, or any combination thereof. The cloud data interface 120 can be coupled to network communication hardware and network connection logic to receive the information from the computing devices. For example, the cloud data interface can be coupled to a local area network (LAN), wide area network (WAN) or the Internet. The cloud data interface 120 may include a queuing mechanism to organize data updates received from or sent to the computing devices. In some embodiments, the cloud data interface 120 is implemented by one or more computing devices different from the storage nodes 112. In other embodiments, the cloud data interface 120 is implemented by a subset or all of the storage nodes 112.
In embodiments, the cloud data interface 120 can be implemented such that existence of individual computing devices that implement the cloud data interface 120 is transparent to a client (e.g., the first electronic device 130 or the second electronic device 140). In embodiments, the cloud data interface 120 and the cloud storage service 110 can be implemented such that existence of the storage nodes 112 that store the client data is transparent to a client (e.g., the first electronic device 130 or the second electronic device 140) of the cloud data interface 120.
The electronic devices (e.g., the first electronic device 130 and the second electronic device 140) can share data amongst each other via the cloud storage service 110. For example, the cloud storage service 110 can maintain one or more application states for one or more applications of one or more electronic devices.
The cloud storage service 110 can maintain an application state database of the application states. The application state database can maintain timestamps of when each of the application states is captured and/or when it is collected. The application state database can maintain different snapshots of application states belonging to the same user account and the same application at different times. Each of the application states can be associated with one or more user profiles, with at least one of the user profiles being an owner of the application state. An owner is a user account having complete rights to the application state. An owner can configure the permission settings of the application state (e.g., who can copy and load the application state). The application state database can maintain these associations between the user profiles and the application states. The application state database can also maintain a list of computing devices that have currently loaded one of the application states, the list including specific application states that each computing device has loaded.
The first electronic device 130 includes a first operating system 132 to manage the hardware resources of the first electronic device 130 and to provide services for running computer applications 134 on the first electronic device 130. The first electronic device 130 can send application data of the computer applications 134, representative of a current application state, to the cloud storage service 110. The first electronic device 130 includes at least a first memory 138 to store the computer applications 134 and the application data associated therewith.
The computer applications 134 can include applications for general productivity and information retrieval, including email, calendar, contacts, news, and stock market and weather information. The computer applications 134 can also include applications in other categories, such as mobile games, file sharing, playing music, media streaming, media creation, media editing, automation, navigation and location-based services, banking, e-reader, order-tracking, ticket purchases, or any combination thereof.
The first memory 138 includes a state synchronization module 136 to update and synchronize the application states with the cloud storage service 110. The first electronic device 130 can execute the state synchronization module 136 on the first operating system 132 or as part of the first operating system 132. The first memory 138 further includes an application share module 137 to facilitate requests between user accounts to share an application state.
Similarly, the second electronic device 140 includes a second memory 148. The second memory 148 includes a second operating system 142, which may be the same or different from the first operating system 132. The second memory 148 can include computer applications 144. The second memory 148 can also include a state synchronization module 146 and an application share module 147 performing the same functionality as the state synchronization module 136 and the application share module 137, respectively. For example, the state synchronization modules 136 and 146 can share a set of source codes further compiled into different binary executables for their respective operating systems. The application share modules 137 and 147 can also share a set of source codes further compiled into different binary executables for their respective operating systems. At least one of the computer applications 144 can overlap with the computer applications 134, such that the application state of the overlapped application can be shared between the first electronic device 130 and the second electronic device 140.
In some embodiments, the cloud storage service 110 can determine when to commit an application state of the first electronic device 130 or the second electronic device 140 to the cloud storage service 110. In other embodiments, the electronic devices 130 and 140 themselves can determine when to commit an application state to the cloud storage service 110. For example, when an application state of the first electronic device 130 is scheduled to be committed to the cloud storage service 110, the first electronic device 130 can send an update message to the cloud storage service 110. To generate the update message, the first electronic device 130 can capture a current application state (e.g., as a set of application data) of one of the computer applications 134 running on the first electronic device 130. The first electronic device 130 can either include the application data of the current application state in the update message or a differential mapping of the application data in the update message. The differential mapping represents the difference between the current application state and a previous application state most recently sent to the cloud storage service 110.
The cloud storage service 110 can provide an interface with the state synchronization modules 136 and 146 to facilitate concurrent updates from one or more of the computer applications 134 and 144. The cloud storage service 110 can determine a current application state of a target application shared across multiple user accounts and/or across multiple electronic devices even when there are multiple conflicting updates (e.g., by prioritizing ranks amongst the conflicting updates and re-integrating them based on the prioritized ranks). The cloud storage service 110 can distribute the current application state to the electronic devices having an instance copy of the target application. The cloud storage service 110 can schedule this distribution such that all electronic devices maintain a consistent instance copy of the application state.
In some embodiments, the electronic devices 130 and 140 do not communicate with each other directly during synchronization. For example, the cloud storage service 110 can perform the synchronization by routing the application state updates from one electronic device to another. In other embodiments, the electronic devices 130 and 140 can directly send application state updates to each other with instructions from the cloud storage service 110 that determines which instance copy to update.
Although FIG. 1 illustrates the first electronic device 130 and the second electronic device 140 as being outside of the cloud storage service 110, in some embodiments, the first electronic device 130 and the second electronic device 140 are part of the cloud storage service 110. For example, the first electronic device 130 or the second electronic device 140 can serve as one of the storage nodes 112. As another example, the first electronic device 130 and/or the second electronic device 140 can implement the cloud data interface 120. In embodiments, the cloud storage service 110 can be implemented by electronic devices that each implements an instance of the state synchronization module 136. Although FIG. 1 illustrates two electronic devices (e.g., the electronic devices 130 and 140), a person having ordinary skill in the art will readily understand that the technology disclosed herein can be applied to data synchronization among more than two computing devices.
FIG. 2 is a block diagram of an example of a system architecture of a computing device 200, in accordance with various embodiments. The computing device 200 can implement an operating system 202. The operating system 202 includes a kernel 204. The kernel 204 provides interfaces to hardware of the computing device 200 for computer applications 240 running on top of the kernel 204 and, on occasions, supervises and controls the computer applications 240. The kernel 204 isolates the computer applications 240 from the hardware. The kernel 204 may include one or more intervening sources that can affect execution of the computer applications 240. In one embodiment, the kernel 204 includes a network I/O module 206, a file I/O module 208, a multi-threading module 210, a user input module 214, a system interrupts module 216, and a shared memory access module 218.
The computer applications 240 can reference and utilize one or more libraries 244 that are accessible through the operating system 202. The libraries 244 can be referenced directly by executable codes 242 of the computer applications 240. A “library” is a collection of instructions that generate a well-defined interface by which software instruction behaviors can be invoked. A library can be linked or loaded to a computer application at the start of the execution of the computer application or in the middle of the execution. Some of the computer applications 240 may also include other instruction frameworks or packages that becomes part of the executable codes 242.
At least a portion of the logic behind the cloud computing system (i.e., the resource sharing platform) can be implemented in one or more modules running on the operating system 202 or as part of the operating system 202. The state synchronization module 220 can be a synchronization agent (e.g., the state synchronization modules 136 and 146 of FIG. 1) discussed above. The application share module 230 can be the app-share agent (e.g., the application share modules 137 and 147 of FIG. 1) discussed above as well.
The state synchronization module 220 can be one of the computer applications 240. The state synchronization module 220 can be at least partly implemented in the executable codes 242. The state synchronization module 220 can also be at least partly implemented by one of the libraries 244 and/or the operating system 202. For example, the state synchronization module 220 can initialize and run a background process on the operating system 202. In embodiments, the state synchronization module 220 can run a service accessible within the operating system 202 and/or across a network.
Similarly, the application share module 230 can be one of the computer applications 240. The application share module 230 can be at least partly implemented in the executable codes 242. The application share module 230 can also be at least partly implemented by one of the libraries 244 and/or the operating system 202. For example, the application share module 230 can initialize and run a background process on the operating system 202. In embodiments, the application share module 230 can run a service accessible within the operating system 202 and/or across a network.
The modules described herein can be implemented as instructions on a tangible storage memory capable of being executed by a processor or a controller. The tangible storage memory may be volatile or non-volatile memory. In some embodiments, the volatile memory may be considered “non-transitory” in the sense that it is not transitory signal. Modules may be operable when executed by a processor or other computing device, e.g., a single chip board, application specific integrated circuit, a field programmable gate array, a network capable computing device, a virtual machine hosting device, a cloud-based device, or any combination thereof. Memory spaces and storages accessible to the modules can be implemented with tangible storage memory as well, including volatile or non-volatile memory.
Each of the modules may operate individually and independently of other modules. Some or all of the modules may be executed by different computing components. The separate computing components can be coupled through one or more communication channels (e.g., wireless or wired channels) to coordinate their operations. Some or all of the modules may reside on different memory devices. Some or all of the modules may be combined as one component or module.
A single module may be divided into sub-modules, each sub-module performing separate method step or method steps of the single module. In some embodiments, at least some of the modules share access to a memory space. For example, one module may access data accessed by or transformed by another module. The modules may be considered “coupled” to one another if they share a physical connection or a virtual connection, directly or indirectly, allowing data accessed or modified from one module to be accessed in another module.
FIG. 3 is a block diagram of an example environment for application state sharing between computing devices (e.g., a computing device 302A, a computing device 302B, and a computing device 302C, collectively as the “computing devices 302”), in accordance with various embodiments. In some embodiments, the computing devices 302 can share application states (e.g., an application state 304A, an application state 304B, and an application state 304C, collectively as the “application states 304”) for an application 306 directly amongst each other. The application states 304 can be shared within a local network 308 (as illustrated) or across a global network 310.
In other embodiments, the computing devices 302 share the application states 304 amongst each other via an application state broker system 312 (e.g., the cloud storage service 110 of FIG. 1). The application state broker system 312 may be connected to the computing devices 302 via the global network 310. The application state broker system 312 can maintain an application state database 314. The application state database 314 can maintain various user-specific application datasets (e.g., an application dataset 316A for a user profile A, an application dataset 316B for a user profile B, and an application dataset 316C, collectively as the “application datasets 316”).
Each of the application datasets 316 can include a synchronization group 318. The synchronization group 318 is a list of computing devices owned by the same user profile (e.g., the user profile A). Computing devices within the synchronization group 318 can maintain one or more consistent instances of one or more computer applications. Each of the application datasets 316 can include application data 320. The application data 320 can represent one of the application states 304. For example, a state synchronization agent (e.g., the state synchronization module 220 of FIG. 2) or an app-share agent (e.g., the application share module 230 of FIG. 2) can use the application data 320 to load one of the application states 304 to a device running the application 306 at a different state than the specific one of the application states 304.
In embodiments where the computing devices 302 share the application states 304 amongst each other via the application state broker system 312, the application data 320 in one of the application datasets 316 can be loaded onto a device that is not listed in the synchronization group 318. For example, the synchronization group 318 of the application dataset 316B may consist of the computing device 302A and the computing device 302B. However, an app-share agent can request the application state broker system 312 to load the application data 320 of the application dataset 316B into the computing device 302C.
FIG. 4 is a block diagram of an example of an application state 400 of a computer application (e.g., one of the computer applications 134, 144, or 244), in accordance with various embodiments. The application state 400 can be represented by application state data, such as the application data 320 of FIG. 3. For instance, application state data can be organized as files and synchronized between the computing devices via a cloud storage service (e.g., the cloud storage service 110 of FIG. 1 or the application state broker system 312 of FIG. 3).
In various embodiments, one or more modules of the operating system of the computing device are responsible for organizing, monitoring, and synchronizing the application state 400. Such modules can run in the computing devices as background services or programs. The computer applications can be developed without any code dedicated to the organization, monitoring, or synchronization of the application state data. The application state data maintained by the operating system includes sufficient information for the operating system to restore a previous snapshot of the application state 400 specified by the application state data.
The application state 400 of a computer application may include application memory data 402, application local storage data 404, hardware configuration data 406, user account configuration data 408, permission settings data 410, or any combination thereof. The application memory data 402 describes an operational state of an operational memory of the computer application. For example, the operational memory can be a portion of a volatile memory (e.g., random access memory or a processor cache) in the computing device that the computer application is running on. For another example, the operational memory can be a portion of a flash memory in the computing device. The operational memory dynamically evolves throughout the execution of the computer application. The application local storage data 404 represents certain data in a local storage of the computing device that the computer application running on. The application local storage data 404 can change based on specific instructions from the computer application to write to a persistent storage device. For example, the local storage can be a portion of a persistent storage device, such as a hard disk or a flash drive.
The hardware configuration data 406 represents how hardware components within the computing device when the computer application is executing. For instance, the hardware configuration data 406 can include a current device sound volume level and a screen brightness level when the computer application is running. The user account configuration data 408 represents a user's preferences and choices regarding the computer application and/or the operating system environment for running the computer application based on previous user inputs. For instance, the user account configuration data 408 may include information about the user's language preference. Assuming the computer application is a game supporting both English and Chinese languages for user interface in the game, the language preference can be the user's selection of the English language as the preferred language.
The permission settings data 410 represents restrictions on who can load the application state 400 and how the application state 400 can be loaded or shared (i.e., loaded onto a device logged in by a user profile who is not an owner of the application state 400). For example, the permission settings data 410 includes a listing of user profiles that can load the application state 400 and/or a list of user profiles that are not allowed to load the application state 400. As another example, the permission settings data 410 can reference a social network account such that only “friends” of the social network account can load the application state 400.
The permission settings data 410 can indicate a number of attributes of how the application state 400 can be shared. The application state 400 can be shared as a “session share,” such that the application state 400 expires after a predetermined amount of time (e.g., from the time of loading the application state 400) or after a precondition for expiration occurs (e.g., the user reaches a certain game level if the computer application is a computer game). The application state 400 can be shared as a “partial share,” such that only part of the application state 400 is loaded. For example, a partial share of the application state 400 can include only sharing of the hardware configuration data 406. The application state 400 can be shared as a “transferable share,” such that the user profile that receives the application state 400 can further share the application state 400 to a third user profile. The application state 400 can be shared as a “separable share,” such that the user profile that receives the application state 400 can maintain a separate application state different from the application state 400 in the cloud storage service once the application state 400 is loaded on to a device of the receiver user profile. The application state 400 can be shared as a “modifiable share,” such that future updates and changes to the application state 400 after it is loaded can be synchronized and re-integrated back into the application state 400 in the cloud storage service.
The application state 400 can be shared as a “complete transfer share,” such that the owner of the application state 400 is changed to the receiver user profile, and the original owner of the application state 400 loses any control or privilege over the application state 400 in the cloud storage service. The application state 400 can be shared as a “co-ownership share,” such that the application state 400 becomes co-owned by the original owner and the receiver user profile. In some embodiments, the application state 400 can include one or more of the above attributes. For example, a transferable sharing of the application state 400 can be a modifiable share as well, where the sharing includes synchronizing of every copy of the application state 400 (e.g., devices of the receiver user profile and the third user profile are added to the synchronization group 318 of the original owner).
In some embodiments, the permission settings data 410 can only be modified by the owner of the application state 400 and not subsequent user accounts that the application state 400. In other embodiments, the permission settings data 410 are layered such that each subsequent user of the application state 400 can add additional permission restrictions without affecting the permission restrictions created by a previous user of the application state 400.
FIG. 5A and FIG. 5B are portions of an activity diagram illustrating a method 500 of sharing an application state of a computer application between computing devices, in accordance with various embodiments. Each of the computing devices can be the computing device 200 of FIG. 2. The method 500 involves an application state broker system 502 (e.g., the cloud storage service 110 of FIG. 1, the application share module 230 of FIG. 2, or the application state broker system 312 of FIG. 3) that manages an application state storage 504. The application state broker system 502 can facilitate sharing of an application state from a source application instance 506 of an application installed on a first computing device 508 to a destination application instance 510 of the application on a second computing device 512. In embodiments, the source application instance 506 can execute on the same computing device as the destination application instance 510. That is, the first computing device 508 can be the second computing device 512. In other embodiments, the source application instance 506 and the destination application instance 510 execute on different computing devices.
The first computing device 508 can execute a synchronization module 514, such as the state synchronization module 220 of FIG. 2. The second computing device 512 can execute an app-share module 516, such as the application share module 230 of FIG. 2.
In step 522, the synchronization agent 514 can log into the application state broker system 502 as user profile A. In response, the application state broker system 502 can authenticate the user profile A. Sometimes later in step 524, the synchronization agent 514 can update application data associated with an application state to the application state broker system 502. Subsequently, in step 526, the application state broker system 502 can store the application data as the application state for the user profile A.
Independent of the activities with the synchronization agent 514, the app-share agent 516 can log into the application state broker system 502 as user profile B in step 528. In response, the application state broker system 502 can authenticate the user profile B. In step 530, the app-share agent 516 can request an application state from the user profile A.
In step 534, the application state broker system 502 can verify permission settings for the application state associated with the user profile A to determine whether the user profile B is allowed to load the application state. If permission is denied to the user profile B, then the application state broker system 502 can send a rejection message to the app-share agent 516. If permission is granted, the application state broker system 502 can check, in step 538, whether the application state in the application state storage 504 is up-to-date.
In some embodiments, if the application state is not up-to-date, then the application state broker system 502 sends, in step 542, an update request to the synchronization agent 514. In response, the synchronization agent 514 can schedule, in step 544, an application state update. In step 546, the synchronization agent 514 can update the application state to the application state broker system 502.
In step 548, the application state broker system 502 configures a sharing copy of the application state based on the request from the app-share agent and the permission settings of the application state. For example, the application state broker system 502 can configure whether the sharing copy is sharable to a third computing device. As another example, the application state broker system 502 can configure whether new application data, generated after executing the sharing copy of the target application, is to re-integrate with the application data of the application state associated with the user profile A in the application state storage 504. The application state broker system 504 can further configure whether new application data, generated after executing the sharing copy of the target application, is to synchronize as new application data of a new application state associated with the user profile B in the application state storage 504. In embodiments, the application state broker system 504 can configure the sharing copy as a session-only instance of the target application that expires in accordance with a schedule or a condition that can be met while executing the session-only instance.
In step 552, the application state broker system 502 can send the sharing copy to the app-share agent 516. Then in step 554, the app-share agent 516 can load the sharing copy of the application state for execution on the second computing device 512.
After step 554, the app-share agent 516 can submit a return copy of the application state back to the application state broker system 502. In response, the application state broker system 502 can determine, in step 562, whether the application state is configured for re-integration with the application state that is originally associated with the user profile A in the application state storage 504. If the application state is configured for re-integration, the return copy is synchronized, in step 564, to associate with devices of both the user profiles A and B. If the application state is not configured for re-integration, the return copy is stored, in step 566, in the application state storage 504 to associate with the user profile B.
FIG. 6 is a flow chart illustrating a method 600 of loading an instance of an application state of a target application into a computing device (e.g., the second computing device 512 of FIG. 5), in accordance with various embodiments. For example, the computing device can be the computing device 200 of FIG. 2. The method 600 begins with an app-share agent (e.g., the application share module 230 of FIG. 2) of the computing device requesting, in step 602, an application state of the target application from an application state broker system. The application state is associated with a foreign user profile different from a current user profile logged into the computing device. The application state broker system, for example, can be the cloud storage service 110 of FIG. 1, the application share module 230 of FIG. 2, or the application state broker system 312 of FIG. 3. The application state can be the application state 400 of FIG. 4.
In response to the request, the application state broker system can send an instance of the application state to the computing device. That is, the computing device receives an instance of the application state from the application state broker system in step 604. Optionally, the app-share agent can back up a current instance of the application state of the target application executing on the computing device in step 606. For instance, the current instance can be stored locally on the computing device. In addition to or instead of storing the current instance locally, the app-share agent can send application data associated with the current instance to the application state broker system to backup the application state of the current instance.
Also optionally, after the application state of the target application has been requested and when the target application has not been installed on an operating system of the computing device, the application state broker system sends and the computing device receives, in step 608, a link or a data stream to download the target application. This feature can enable a convenient single-step application sharing mechanism for a user account to borrow an application from another user account even when the user account does not possess the application on his/her device.
Upon receiving the instance of the application state, the app-share agent configures, in step 610, the target application with the instance of the application state for executing on the computing device. In embodiments, the app-share agent can merge the received instance of the application data with the current instance already on the first computing device. For example, the app-share agent can use the hardware configuration data of the current instance and the application memory data of the received instance to load the target application. Once step 610 is completed, either the user of the computing device can manually or the app-share agent can automatically execute the configured target application on the computing device in step 612. After the configured target application has been executed, a synchronization agent (e.g., the state synchronization module 136 of FIG. 1 or the state synchronization module 220 of FIG. 2) can update changes to the application state of the configured target application back to the application state broker system in step 614.
Various methods of configuring the target application is contemplated in this disclosure. In some embodiments, the configuration of the target application is transparent to the target application. For example, step 610 can include: pausing or terminating the target application in sub-step 622; modifying a portion of a memory allotted for the target application in the computing device in sub-step 624; and unpausing or restarting the target application in sub-step 626. In other embodiments, the target application includes built-in logic to facilitate loading of an instance of a new application state. For example, step 610 can include: passing the instance of the application state to the target application in sub-step 632; and configuring the target application based on the instance of the application state and logical instructions within the target application in sub-step 634. In sub-step 632, the app-share agent can pass the instance of the application state to the target application while the target application is executing on the computing device. Alternatively, the app-share agent can initialize the target application with the instance of the application state if the target application is not running on the computing device.
While processes or methods are presented in a given order, alternative embodiments may perform routines having steps, or employ systems having blocks, in a different order, and some processes or blocks may be deleted, moved, added, subdivided, combined, and/or modified to provide alternative or subcombinations. Each of these processes or blocks may be implemented in a variety of different ways. In addition, while processes or blocks are at times shown as being performed in series, these processes or blocks may instead be performed in parallel or may be performed at different times.
