If the sharing menu is selected, displaying a sharing interface, wherein the sharing interface comprises two external devices, namely a device B and a device C. If the equipment B is selected, an application selection interface is displayed, wherein the application selection interface comprises Word and WPS. If the Word is selected, a data sharing request from the file manager of the device A to the Word of the device B is sent out, and the data sharing request indicates that the document to be shared is to be shared from the file manager of the device A to the Word of the device B.
It should be appreciated that, in addition to the shareable external device, the sharing interface of the file to be shared may also include a local application of the first electronic device, such as a printer, email, weChat, QQ, etc. The first electronic device may share the sharable file to a local application to implement data sharing within the device.
In another embodiment, the file list is displayed after the first application (e.g. the file manager) is started, and if the picture to be shared in the long press file list is detected, the sharing menu is displayed.
In another embodiment, the sharing interface may directly display an application of the external device (e.g., a second application of the second electronic device). If the user selects an application of the external device (e.g., a second application of the second electronic device) from the sharing interface, a data sharing request is issued from the first application of the first electronic device to the application of the external device (e.g., the second application of the second electronic device).
The in-device file identification information is used for in-device file location and may uniquely identify a file on a device (e.g., a first electronic device). The in-device file identification information may be a file path or a file identification in a database, such as a uniform resource identifier (Uniform Resource Identifier, URI). The first electronic device can locate the file to be shared according to the file identification information in the device, and the external device cannot locate the file to be shared according to the file identification information in the device.
The source device information is used to identify the first electronic device. The source device information may be a device identifier of the first electronic device.
The source application information is used to identify the first application. The source application information may be an application identifier of the first application.
The destination device information is used to identify the second electronic device. The destination device information may be a device identifier of the second electronic device.
The destination application information is used to identify the second application. The destination application information may be an application identifier of the second application.
The operation authority information designates the operation authority of the file to be shared and is used for checking the operation authority of the second application. The operation authority information set by the user may be received, or default operation authority information may be used.
The operation permission information may specify whether the second application has a read permission or a write permission for the file to be shared.
The operation permission information may further specify whether the second application has the sharing permission for the file to be shared. The sharing permission refers to whether the second application can share the file to be shared in the device, that is, share the file to other applications in the second electronic device. If the operation authority information designates sharing authority, the second application can share the file to be shared to other applications in the second electronic device. Otherwise, if the operation authority information designates no sharing authority, the second application cannot share the file to be shared to other applications in the second electronic device.
The operation authority information may also specify an operation validity period. And in the operation validity period, the second application can operate the file to be shared.
202, A first application shares a file to be shared to a first sharing module, and transmits file identification information in equipment, source equipment information, source application information, destination equipment information, destination application information and operation authority information to the first sharing module.
The first application can share the file to be shared to the first sharing module through a Binder mechanism. Binder is an inter-process communication mechanism, a first application corresponds to a process, and a first sharing module corresponds to a process. When the first application shares the file to be shared to the first sharing module system through the Binder mechanism, the operating system allocates a temporary area for the file to be shared, and the operation of the temporary area is reflected on the file to be shared.
And 203, the first sharing module generates inter-device file identification information of the file to be shared according to the intra-device file identification information and the source device information, and stores the intra-device file identification information, the inter-device file identification information and the operation authority information.
The inter-device file identification information is used for file location across devices. And the second electronic equipment can determine the position of the file to be shared according to the identification information between the devices of the file to be shared.
In one embodiment, the intra-device file identification information, the inter-device file identification information may be a uniform resource identifier.
The first sharing module may add the source device information to the file identification information in the device, and generate file identification information between the devices. For example, the in-device file identification information is content:// media/external/file/1, the source device information is 123456, and the inter-device identification information may be content:// media/external/file/1.
And 204, the first sharing module pulls up the second application according to the destination equipment information and the destination application information, and sends the file identification information between the equipment to the second application.
It should be appreciated that, to improve the security of the data transmission, the first sharing module may encrypt the inter-device file identification information before sending the inter-device file identification information to the second application.
And 205, the first sharing module sends the file identification information between the devices, the destination application information and the operation authority information to the second sharing module according to the destination device information.
In this embodiment, the first sharing module transmits the operation permission information to the second sharing module, so that the second sharing module performs the first operation permission check on the file operation of the file to be shared by the second application according to the operation permission information, thereby improving the operation security.
In other embodiments, the first sharing module may not transmit the operation permission information to the second sharing module, and the second sharing module does not perform the first operation permission check on the file operation of the file to be shared by the second application.
It should be appreciated that, in order to improve the security of data transmission, the first sharing module may encrypt the inter-device file identification information, the destination application information, and the operation authority information before transmitting the inter-device file identification information, the destination application information, and the operation authority information to the second sharing module.
And 206, the second sharing module identifies whether the file to be shared is an external file according to the file identification information among the devices, and returns the identification result of the file to be shared to the second application according to the target application information.
In this embodiment, after receiving the inter-device file identification information from the first sharing module, the second application sends a file identification request to the second sharing module, and after receiving the file identification request, the second sharing module identifies whether the file to be shared is an external file according to the inter-device file identification information, and returns an identification result of the file to be shared to the second application according to the destination application information.
The second sharing module can analyze the source device information from the file identification information among the devices, and judge whether the file to be shared is an external file or not according to the analyzed source device information. For example, the second sharing module analyzes that the source device information is 123456 from the inter-device file identification information content of 123456:// media/external/file/1, and the 123456 represents the first electronic device instead of the device (i.e., the second electronic device), and determines that the file to be shared is an external file.
207, If the file to be shared is an external file, the second application performs the first file operation on the file to be shared through the second sharing module.
The first file operation to share the file may include reading the file, writing the file, sharing the file in the device, and so on.
208, The second sharing module performs a first operation authority check on the first file operation according to the operation authority information.
Performing a first operation authority check on the first file operation according to the operation authority information includes: if the first file operation is the operation in the authority specified by the operation authority information, allowing the first file operation; and if the first file operation is not the operation in the authority specified by the operation authority information, rejecting the first file operation. For example, the second application only has read rights and no write rights to the file to be shared, and if the first file is operated as a write operation, the write operation is denied.
The first operation authority check is carried out in the second electronic equipment, so that illegal operation can be intercepted in advance, the safety of file operation is improved, and the communication overhead between the first electronic equipment and the second electronic equipment during illegal operation can be reduced.
209, If the first operation authority check is passed, the second sharing module generates a file operation request according to the first file operation, and sends the file operation request to the first sharing module, where the file operation request includes the inter-device file identification information, the destination application information, the destination device information, and the operation information of the first file operation of the file to be shared.
The operation information indicates a first file operation, such as a write operation, performed by the second application on the sharable file.
It should be appreciated that in order to increase the security of the data transfer, the second sharing module may encrypt the file operation request before sending the file operation request to the first sharing module.
210, The first sharing module searches corresponding file identification information and operation authority information in the device according to the file identification information between the devices in the file operation request.
And 211, the first sharing module performs second operation authority check according to the searched operation authority information and the operation information in the file operation request.
The performing of the second operation authority check according to the operation authority information and the operation information may include:
and judging whether the operation type corresponding to the operation information is the designated operation type.
For example, the file operation request indicates that writing operation is performed on the file to be shared, the first electronic device determines whether the second application has writing permission on the file to be shared according to the operation permission information, and if the second application has writing permission on the file to be shared, the second electronic device passes through the second operation permission check of the operation type.
The performing the second operation authority check on the operation information according to the operation authority information may further include:
and judging whether the operation time corresponding to the operation information is within the appointed operation effective period.
For example, the operation time designated by the operation permission information is 30 minutes after the second electronic device receives the external location information, the source device information, the source application information, the destination application information and the operation permission information, and if the second application operates the file to be shared in the time period content, the second operation permission of the operation time is checked.
212, If the second operation authority is checked, the first sharing module performs a second file operation on the file to be shared according to the found file identification information and operation information in the device.
The first sharing module can search the file descriptor of the file to be shared according to the searched file identification information in the device, operate the file to be shared according to the searched file descriptor and the operation information, and return the operation result to the second electronic device.
For example, the first sharing module performs writing operation on the file to be shared according to the searched file descriptor and the operation information.
213, The first sharing module returns the operation result to the second sharing module according to the destination device information in the file operation request.
It should be appreciated that, to improve the security of data transmission, the first sharing module may encrypt the operation result before returning the operation result to the second sharing module.
214, The second sharing module returns the operation result to the second application.
And the second application displays the file to be shared according to the operation result. For example, the second application displays the written file to be shared according to the operation result of the writing operation.
According to the method and the device, the sharable file is shared from the first application of the first electronic device to the first application of the second electronic device, so that cross-device and cross-application data sharing is realized. According to the method and the device, cloud is not needed when data sharing is carried out, the type of the shared data is not limited, and the application range and the efficiency of the data sharing are improved.
In another embodiment, before the obtaining the in-device file identification information, the source device information, the source application information, the destination device information, the destination application information, and the operation authority information of the file to be shared, the method further includes:
Searching a second electronic device;
And if the second electronic equipment is found, connecting the second electronic equipment.
The first electronic device may search for the second electronic device by means of infrared rays or the like, and if the second electronic device is found, the second electronic device is connected.
