Detailed ways

With the proliferation of smart devices, many people own two or more devices. In the process of using these devices, for some applications, it may be necessary to obtain a better experience through the collaborative work between different devices. Therefore, the collaborative work technology applied between different devices emerges as the times require. For example, in a multi-person conference, the presenter (or the chairman) can work collaboratively between the mobile phone and the large screen (such as a smart screen) through the office application, and the document on the mobile phone, as well as the doodling and page turning operations on the document. Displayed on a large screen (eg, a smart screen). For another example, when playing a game on a large screen, the player can use the mobile phone as a gamepad to operate and control the game on the large screen through the cooperative work between the mobile phone and the large screen through the game application.

Usually, the collaborative work of applications between different devices is realized through cloud servers. That is, the cooperative instructions applied between two or more devices are forwarded through the cloud server. For example, in the scenario where the mobile phone is used as a gamepad to operate and control the game on the large screen through the cooperative work between the mobile phone and the large screen through the game application, the player can use the game client on the mobile phone to control the game on the large screen. Scan the QR code generated by the client, so that the game client on the mobile phone and the game client on the large screen respectively establish a connection with the cloud server. When the player operates through the game client on the mobile phone, the mobile phone can send the operation instruction of the game client (that is, the collaborative instruction) to the cloud server, and then the cloud server forwards the operation instruction to the big screen, so that the game The game client can respond according to the operation command received by the large screen, and generate the corresponding game screen.

It can be seen that at present, the collaborative work of applications between different devices is realized through cloud servers, which requires application service providers to deploy corresponding servers, and the cost is relatively high. In addition, through the cloud server forwarding the cooperative instructions applied between two or more devices, the transmission path of the cooperative instructions is long, and the transmission quality of the cooperative instructions has a strong dependence on the network quality. Therefore, when the cooperative work between the devices responds The higher the delay, the lower the stability. As a result, the user experience is poor for scenarios with high latency requirements, such as multi-person conferences and instant games.

In order to solve the above problem, an embodiment of the present application provides a method for inter-device applications to work cooperatively, and the method can be applied to a scenario where applications work cooperatively between different devices.

For example, FIG. 1 is a schematic diagram of an application scenario of a method for inter-device application collaboration provided by an embodiment of the present application. As shown in Figure 1, users can use office applications (eg,

As shown in (c) of FIG. 2 , the user can scan the two-dimensional code displayed on the large screen 201 through the mobile phone 202 . After the mobile phone 202 scans the two-dimensional code, it can establish a connection with the large screen 201 according to the two-dimensional code, and as shown in (d) in FIG. As another example, as shown in (a) of FIG. 3 , the large screen 301 may display a prompt for prompting the user to use the near field communication (NFC) technology for collaborative work, such as "Please turn on the mobile phone. NFC, touch the remote". When the user needs to display the document on the mobile phone 302 on the large screen 301, the user can use the operation shown in (b) of FIG. 2 to activate the function of sharing the document on the mobile phone. In response to this operation, the mobile phone 302 is able to activate the NFC tap function. As shown in (b) of FIG. 3 , the user can touch the mobile phone 302 with the remote control 303 . When the mobile phone 302 touches the remote control 303, the mobile phone 302 can establish a connection with the large screen 301 according to the data transmitted by the NFC when touching, and as shown in (c) of FIG. Synchronized to the large screen 301 for display. As shown in FIG. 1 , the user can also share the document displayed on the large screen 102 and the operations such as graffiti on the document to the tablet 103 through the collaborative work between the tablet 103 and the large screen 102 through the office application. As an example, as shown in (a) of FIG. 4 , when displaying a document, the large screen 401 may also display a two-dimensional code (wherein, the document displayed on the large screen 401 may be as shown in FIG. 2 or FIG. 3 ). In the scenario shown, the document on the mobile phone displayed on the large screen synchronously is as shown in (d) in Figure 2 or (c) in Figure 3. It can also be directly displayed on the large screen 401 and stored in it. documentation, etc.). When the user needs to synchronize the document displayed on the large screen 401 to the tablet 402 , as shown in (b) in FIG. 4 , the user can scan the two-dimensional code displayed on the large screen 401 through the tablet 402 . After the tablet 402 scans the two-dimensional code, it can establish a connection with the large screen 401 according to the two-dimensional code. And as shown in (c) of FIG. 4 , the tablet 402 can display the documents synchronized by the large screen 401 .

For another example, FIG. 5 is a schematic diagram of an application scenario of another method for inter-device application collaboration provided by an embodiment of the present application. As shown in FIG. 5 , the user can use the mobile phone 501 as a gamepad to operate and control the game on the large screen 502 through the cooperative work of the game application between the mobile phone 501 and the large screen 502 (eg, a smart screen). As an example, as shown in (a) of FIG. 6 , when displaying the picture of the game application, the large screen 601 may also display a two-dimensional code. When the user needs to use the mobile phone 602 as a gamepad to control the game application on the large screen 601 . As shown in (b) of FIG. 6 , the user can scan the two-dimensional code displayed on the large screen 601 through the mobile phone 602 .

For another example, the second electronic device can obtain the encoded information from the first electronic device by means of NFC touch (for example, the mobile phone as shown in FIG. 3 or FIG. 7 is connected to the large screen by touch). Therefore, information exchange between the first application and the second application can be performed directly through the connection established between the first electronic device and the second electronic device, that is, the first application and the second application are between the first electronic device and the second electronic device.

An electronic device is connected, and the first application and the second application are bound. Wherein, as an example, the information contained in the two-dimensional code generated by the first electronic device (that is, the coding information contained in the two-dimensional code, or referred to as two-dimensional code information) can be referred to as shown in Table 1.

The server-side APP refers to the corresponding APP on the electronic device that generates the QR code for the applications to work together. For example, taking the above-mentioned first electronic device to generate a two-dimensional code and the above-mentioned second electronic device to scan the two-dimensional code as an example, the server is the first electronic device, and the server APP is the first application on the first electronic device. The APP to be pulled up is the second application on the second electronic device, and the activity expected to be pulled up is the activity of the second application that is expected to be pulled up. It should be noted that the PKG field, that is, the name of the APP package expected to be pulled up, can be automatically filled in by the caller of the ARS read Binder.

S1101. The first application binds the ARS service. Correspondingly, the ARS binds the device management module, and after the binding is successful, the device management module calls back the binding success message to the ARS, and accordingly, the ARS calls back the binding success message to the first application.

For example, the first application is an application integrated with ARS kit. The first application can call the initialization interface in the ARS kit, and trigger onServiceConnected through the bindService mechanism to bind the ARS service and the device management module.

The first application is bound with the ARS and the device management module, which can facilitate subsequent interface invocation and information exchange between the first application, the ARS, and the device management module.

S1102. The first application sends application information to the ARS.

The application information may include the page name of the second application that is expected to be pulled up (that is, the page name that is expected to be pulled up), the package name of the first application (that is, the package name of the server APP), and the package name of the second application (that is, the package name of the server-side APP). The package name of the APP that is expected to be pulled), the minimum version number of the desired second application (that is, the lowest version number of the APP that is expected to be pulled), and the system flag of the second application (that is, the system flag of the APP that is expected to be pulled) ( For example, android

system, Hongmeng system, etc.). The package name of the first application and the package name of the second application may be the same or different.

As an example, the first application may send application information by invoking the two-dimensional code generation interface genQrCode(bundle, new IAppRouter.GenQrListener()) provided in its integrated ARS kit. The bundle can be filled with specific application information. For example, bundle can be filled with:

bundle.putString(ACTIVITY, "cn.wps.moffice.lite.huawei_ars.MainActivy"), that is, the page name of the second application to be pulled up is "cn.wps.moffice.lite.huawei_ars.MainActivy";

bundle.putString(PACKAGE_NAME, "cn.wps.moffice.lite.huawei_ars"), that is, the package name of the second application is "cn.wps.moffice.lite.huawei_ars";

bundle.putString(APP_VERSION,20001001), that is, the expected minimum version number of the second application is "20001001";

bundle.putString(OS_TYPE,TYPE_ANDROID_OS), that is, the system type of the second application is Android

The system, that is, the second application is an Android application.

It should be noted that, in some possible implementation manners, the above S1101 may not be executed, that is, the first application may not be bound to the ARS service. The first application may directly send application information to the ARS. There are no restrictions here.

S1103. The ARS invokes the device management module to acquire networking information from the device management module. Correspondingly, the device management module returns the networking information to the ARS.

The networking information may include the device network ID of the first electronic device, the device IP address, and the hash-encrypted ID of the logged-in account.

As an example, the ARS may acquire networking information from the device management module by calling the interface getLocalDeviceInfo provided by the device management module.

It should be noted that, before S1103, or after S1103, or when S1103 is executed, the ARS may also generate a connection trust PIN code. In some possible implementations, the connection trust PIN code may be refreshed at a fixed time. For example, ARS refreshes the connection credit PIN code every 5 minutes.

S1104. The ARS sends a request for configuring group information to the device management module. The request can carry the connection credit PIN code (PIN code) generated by ARS, and the application information obtained by ARS in S1102, such as the package name of the first application (or called the server package name (serverPkg)) and the second The package name of the application (or client package name (clientPkg)). Correspondingly, the device management module sends a request for creating a device authentication group to the security management module. The request may carry the first application package name, the second application package name and the connection credit PIN carried in the request for configuring group information sent by the ARS. After the security management module creates a device authentication group according to the received request, it can return a successful creation response to the device management module, and the response can carry the group information of the created device authentication group, such as group ID and group name etc. The device management module stores the group information after receiving the creation success response, and can also return the creation success response to the ARS.

Wherein, the security management module can generate group information, such as the above-mentioned group ID and group name, according to the package names of the applications (eg, the package names of the first application and the second application) and the connection trust PIN code.

In some possible implementations, the ARS may send a request for configuring group information to the device management module through the setServerAuth interface. The device management module can send a request for creating a device authentication group to the security management module through the setAuthInfo interface.

S1105. The ARS invokes the device management module to acquire group information. Correspondingly, the device management module returns group information to the ARS.

The ARS can obtain group information by calling the getAuthInfo interface provided by the device management module.

It should be noted that, in some possible implementation manners, the above S1104 and S1105 may also be executed before S1103, or S1104 may be executed first, and then S1103 and S1105 may be executed (wherein, the sequence between S1103 and S1105 may be omitted. Restriction, that is, S1103 may be executed first and then S1105 may be executed, or S1105 may be executed first and then S1103 may be executed, or S1103 and S1105 may be executed simultaneously), which is not limited in this embodiment of the present application.

S1106. The ARS generates two-dimensional code information according to the obtained application information, networking information, group information, and the generated connection credit PIN code. Correspondingly, the two-dimensional code information is returned to the first application.

It should be noted that the generated two-dimensional code information may include the content shown in Table 1.

The ARS may return the two-dimensional code information to the first application through the GenQrListener callback of the genQrCode interface used by the first application to send the application information to the ARS in S1102.

S1107. The first application displays a two-dimensional code picture. The two-dimensional code picture contains the above two-dimensional code information.

It should be noted that, when the connection trust PIN code generated by the ARS is refreshed, the ARS may send a connection trust PIN code timeout notification to the first application. After receiving the connection trust PIN code timeout notification, the first application can re-execute the above S1101 to S1107 to regenerate and display the two-dimensional code.

In the embodiment of the present application, it is taken as an example that the second electronic device establishes a communication connection with the first electronic device by scanning a two-dimensional code containing coded information displayed by the first electronic device. When the first application on the first electronic device and the second application corresponding to the first application on the second electronic device need to work together, if the first electronic device generates a QR code, the user can use the second electronic device to generate a QR code.

The content of the two-dimensional code is the same as the content of the two-dimensional code generated in the method shown in FIG. 11 . For example, the QR code content obtained by ARS parsing the QR code information may include the page name of the second application to be pulled up, the package name of the first application, the package name of the second application, and the expected minimum version number of the second application, The system flag of the second application. and the device network ID of the first electronic device, the device IP address, and the hash-encrypted ID of the logged-in account. And the connection credit PIN code, group ID and group name, etc.

As an example, when the content of the QR code parsed by ARS lacks a required parameter, or the required String type parameter is an empty string or a zero value (null), the second electronic device may pop up a box to prompt the specific error message, and end the process of scanning the QR code for networking. For example, as shown in FIG. 13 , the second electronic device may display a pop-up box prompting "invalid QR code".

It should be noted that the above mandatory parameters are the parameters necessary for scanning the QR code to form a network. For example, the feature code information of the two-dimensional code information, the page name of the second application to be pulled up, the package name of the first application, the package name of the second application, and the device network ID and device IP address of the first electronic device, And the connection credit PIN code, group ID and group name, etc.

Optionally, after the ARS obtains the two-dimensional code content, it can also check whether the second application has been installed according to the second application information in the two-dimensional code content. For example, the following S1203 is performed.

S1203, the ARS checks whether the second application has been installed. It should be noted that, when the QR code content obtained by the ARS further includes the expected minimum version number of the second application, the ARS may also check whether the version number of the second application satisfies the minimum version number. Correspondingly, when the second application has been installed and the version number of the installed second application meets the minimum version number, the ARS can launch the second application, and when the second application is launched, the ARS can be invoked to perform initialization. In some possible implementations, when the second application is not installed, the application market can be jumped to to facilitate the user to download and install the second application.

For example, the ARS can launch the second application by calling startActivity. The request (Intent) sent when calling startActivity to start the second application may carry parameters required for ARS initialization (eg, ARS_BUNDLE). The second application can call the collaborative module initialization interface initDataModel(Bundle params, Context context) of ARS to initialize. Among them, param is filled in with the received Intent parameter, for example, ARS_BUNDLE.

S1204. The ARS binds the service of the device management module. Correspondingly, after the binding is successful, the device management module may return a binding successful response to the ARS.

The ARS can bind the device management module by calling the bindService interface.

S1205. The ARS sends a request for configuring group information to the device management module. Correspondingly, the device management module invokes the second security management module (ie, the security management module of the second electronic device) to configure group information. After the group information is successfully configured, the second security management module may return a configuration success response to the device management module, and the device management module may return a configuration success response to the ARS.

For example, the ARS may send a request for configuring group information to the device management module through the setAuthInfo interface. The request may carry group information obtained after parsing the two-dimensional code information, such as group name, group ID, connection credit PIN code, package name of the first application and package name of the second application, etc. The device management module can store the group information.

It should be noted that, in some possible implementation manners, the above S1204 may not be executed, that is, the ARS does not need to bind the services of the device management module, and can directly send a request for configuring group information to the device management module, which is not performed here. limit.

After the group information is configured by the second security management module, the electronic device can connect to the communication module of the first electronic device through the second communication module, for example, perform the following S1206.

S1206. The ARS invokes the device management module, and invokes the second communication module (ie, the communication module of the second electronic device) through the device management module to connect to the communication module (ie, the first communication module) of the first electronic device. The ARS may send a device connection request (eg, connectDevice) (or referred to as a first request) to the device management module by invoking the connect interface of the device management module, and the request may include the device of the first electronic device obtained in S1202 Parameter information required for device connection, such as network ID, device IP address, port ID, and connection trusted PIN code, as well as application information such as the package name of the first application and the package name of the second application. The device management module can call the second communication module to forward the device connection request (or referred to as the first request) to the communication module of the first electronic device, so that the ARS can call the device management module, and the second communication module can be called to connect through the device management module. A communication module of the first electronic device.

S1207, the first communication module invokes the first security management module (ie, the security management module of the first electronic device) to perform security verification. Correspondingly, when the security management module of the first electronic device passes the verification, the first security management module can return a response that the verification is passed to the first communication module. After the first communication module receives the response that the verification passes, it can establish a connection with the communication module of the second electronic device, and return a successful connection response to the communication module of the second electronic device, and then the communication module of the second electronic device can report to the device. The management module sends a message that the device goes online, and accordingly, the device management module of the second electronic device may return a connection success response to the ARS.

It should be noted that the security management module of the first electronic device (ie the first security management module) and the security management module of the second electronic device (ie the second security management module) can pass through the temporary channel between the communication modules of the two devices or a dedicated channel for information exchange, so that the security management module of the first electronic device can obtain the group information (eg, group ID, etc.) configured by the security management module of the second electronic device from the security management module of the second electronic device , so as to facilitate the security management module of the first electronic device, according to the obtained group information, PIN code, application package name (such as the first application package name and the second application package name) configured after scanning the code of the second electronic device, and The first electronic device performs security verification by checking whether the group information, PIN code, and application package name configured by itself are consistent when generating the two-dimensional code. When the above information is consistent, the verification is successful.

Optionally, after the first electronic device establishes a communication connection with the second electronic device, the ARS may also notify the second application that the connection is successful, so that the second application knows that the connection is successful and then performs subsequent steps of binding with the first application. For example, the following S1208 is performed.

S1208. The ARS sends a notification that the device is connected successfully to the second application.

In the embodiment of the present application, it is taken as an example that the second electronic device establishes a communication connection with the first electronic device by scanning a two-dimensional code containing coded information displayed by the first electronic device.

For example, take the scenario shown in Figure 1 as an example. That is, take the first electronic device as a smart screen and the second electronic device as a mobile phone or tablet as an example. After the mobile phone or tablet is connected to the network by scanning the QR code on the smart screen, the second application on the mobile phone or tablet (for example, the mobile version of the office application) can be connected with the first application on the smart screen (for example, the TV version of office application). application) to bind to realize cross-device interaction between the second application on the mobile phone or tablet and the first application on the smart screen.

As an example, when the user needs to display the document on the mobile office application on the mobile phone and the operation on the document on the smart screen for a meeting. Users can first open the TV version of the office application on the smart screen. After the smart screen opens the TV version of the office application, the QR code image used to connect to the conference can be displayed. The user can open the mobile version of the office application on the mobile phone and open the document to be used, and then choose to start the meeting on the interface displayed on the mobile phone, so that the mobile phone can call the camera to scan the QR code. When the user scans the QR code image displayed on the smart screen through the mobile phone, the mobile phone and the smart screen can establish a communication connection, and bind the mobile version of the office application on the mobile phone with the TV version of the office application on the smart screen. After that, the smart screen can display the documents opened by the mobile version of the office application on the mobile phone, as well as the page turning and graffiti operations on the document. When the smart screen displays the documents of the mobile version of the office application, the QR code image used to connect to the meeting can also be displayed, so that users can scan the QR code to join the meeting through other electronic devices. When other users need to join the meeting, such as when the user needs to enter the meeting through the tablet, the user can scan the QR code image on the smart screen displaying the document through the tablet camera, so as to establish a communication connection between the tablet and the smart screen, and connect the tablet to the smart screen. The mobile version of the office application on the smart screen is bound to the TV version of the office application on the smart screen. After that, the document displayed on the smart screen and the operations on the document can be displayed on the tablet.

S1403 , the mobile office application of the mobile phone sends a request (or referred to as the second request) for binding the service of the TV version office application of the smart screen to the DEF of the mobile phone (or called the second DEF, to be distinguished from the DEF of the smart screen). ).

For example, the mobile office application may use the cross-device service binding interface connectAbility(Intent intent, IAbilityConnection conn) of the second DEF to send the above request to the second DEF. Wherein, the request can carry intent.setElement(new ElementName(netId,pkgName,serviceName)), that is, the device network ID of the smart screen, the application package name of the TV version of the office application, the service name to be bound, etc. It should be noted that since the ARS of the mobile phone in S1402 can obtain the device network ID of the smart screen, the application package name of the TV version of the office application, the service name to be bound and other parameter information through the QR code analysis, the parameters carried in the above request are Information can be obtained from the mobile phone's ARS by the mobile office application.
