The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

When the terminal manages each device connected to the terminal, it needs to be implemented by the device application corresponding to each device on the terminal, and when there are many devices connected to the terminal, the device applications on the terminal are increased, which is inconvenient to manage. In the prior art, for such a phenomenon, an equipment center application is usually set in a terminal, the equipment center application is used as a management platform of the equipment application to manage each equipment application, and each equipment application displays a display interface of the equipment center application.

Generally, in an equipment center application, only a default icon of each equipment application is displayed, and a device picture of a device managed by each equipment application cannot be visually displayed, so that a user cannot directly see the device appearance of a device connected to a terminal in an application interface of the equipment center application, and can check the device appearance of the connected device only by entering a corresponding equipment application, which brings inconvenience to the user.

The application provides a cross-application picture display method, which can display the device pictures of all devices connected with a terminal on a display page of a device center application for managing all devices connected with the terminal.

Before describing the embodiments of the present invention more clearly, some concepts of the present invention will be described in detail to better understand the present invention.

The picture descriptor: the target picture for locating the query may be, for example, a file format of the picture, a content feature of the picture, a picture version number, and the like.

Inlet flow: reading bytes from the file, and reading the data in the hard disk file into the memory for use.

Referring to fig. 1, a system architecture diagram of a cross-application picture display method is provided for an embodiment of the present application.

As shown in fig. 1, the system architecture may include a terminal 100, a device cloud 101, a device 102, and a device center application 1001 and a device application 1002 disposed in the terminal 100. The terminal 100 may be various electronic devices, and the devices 102 including but not limited to a smart watch, a smart phone, a tablet computer, a laptop portable computer, a desktop computer, etc. may be various internet of things devices including but not limited to a refrigerator, a washing machine, an air conditioner, a television, an earphone, etc. The device cloud 101 is a server storing device detailed information of each device, and developers can perform system upgrade or software update for each device through the device cloud. The device center application 1001 is used to manage each device application 1002 and provide a channel for opening the device application 1002. The device application 1002 is for managing each device 102 connected to the terminal.

It should be understood that the number of device clouds, devices, and device applications disposed in the terminal in fig. 1 is merely illustrative, and any number of device clouds, devices, and device applications disposed in the terminal may be used according to implementation requirements.

The following is a detailed description with reference to specific examples. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims. The flow diagrams depicted in the figures are merely exemplary and need not be performed in the order of the steps shown. For example, some steps are parallel, and there is no strict sequence relationship in logic, so the actual execution sequence is variable.

Referring to fig. 2 in conjunction with the system architecture diagram shown in fig. 1, a schematic flow chart of a cross-application picture display method is provided in an embodiment of the present application. The embodiment of the present application takes the application of the method to a terminal as an example for explanation. As shown in fig. 2, the cross-application picture display method may include the following steps S101 to S103.

S101, reading a target picture corresponding to target equipment from a file directory applied by the target equipment, and analyzing the target picture and equipment information of the target equipment to obtain a picture descriptor corresponding to the target picture;

the target device may refer to a device connected to the terminal, and the target device application refers to an application for controlling the target device. For example, if the target device is an earphone, the target device application is an application for controlling the earphone, and the target application may perform control operations such as volume adjustment and sound effect mode switching on the earphone. For another example, if the target device is a refrigerator, the target device application is a refrigerator application for controlling the refrigerator, and the refrigerator application may perform control operations such as temperature adjustment and freezing mode switching on the refrigerator.

It is worth mentioning that each target device application controls more than one target device, for example, the target device application is a refrigerator application controlling a refrigerator, and in case that there is more than one refrigerator connected to the terminal, the refrigerator application can control a plurality of refrigerators connected to the terminal respectively.

Specifically, a target picture corresponding to a target device is read from a file directory applied by the target device, and then the target picture and device information of the target device are analyzed to obtain a picture descriptor corresponding to the target picture.

Optionally, before reading a target picture corresponding to a target device connected to a terminal in a file directory of a target device application, in a possible specific implementation scenario, after the target device is connected to the terminal, a target device application corresponding to the target device in the terminal may acquire device information of the target device, where the device information may be a device model of the target device or another device identifier that may represent the target device, and then the target device application may download a device picture of the target device from a device cloud of the target device to the file directory corresponding to the target device application according to the device information of the target device.

Optionally, the device pictures downloaded from the device cloud by the target device application may include multiple device pictures, and one device picture is read from any of the device pictures as the target picture corresponding to the target device.

It should be understood that the target picture is one of a plurality of device pictures of the target device.

Optionally, the manner of reading the target picture corresponding to the target device from the file directory applied by the target device may be to read the target picture corresponding to the target device in a packet management manner.

Optionally, the manner of reading the target picture corresponding to the target device from the file directory applied by the target device may be that a Uniform Resource Identifier (URI) of the target picture is provided by a file provider, and then the position of the target picture is located based on the URI and the target picture is read.

Optionally, the reading of the target picture corresponding to the target device from the file directory applied by the target device may be performed by selecting an appropriate manner according to the number of devices currently connected to the terminal. In a possible implementation manner, if the number of devices is less than a device number threshold, obtaining an input stream of a target picture from a file directory of the target device application through packet management; if the device number is larger than or equal to the device number threshold, acquiring a universal resource identifier of a target picture in a device application of the target device through a file provider, and acquiring an input stream of the target picture from a file directory of the target device application through a content provider based on the universal resource identifier. The devices connected with the terminal include devices in a connected state and devices which are connected once.

Optionally, the picture descriptor includes at least one of a device model, a device color, a device brand, a picture type, a presentation type, a version number, and a picture suffix.

For example, each picture descriptor may be defined as:

modelId	String
		colorId	String
brand	String
		imageType	DeviceImageType
displayType	ImageDisplayType
		shortcutId	String＝"0"
version	Long＝0L
		suffix	String＝".png"

wherein modelId is the device model, colorId is the device color, brand of equipment, imageType is the picture type, displayType is the show type, shortcutId is the shortcut path descriptor, version is the version number, and suffix is the picture suffix.

It should be understood that the picture descriptors are not identical in content according to the device picture definitions of different target devices, and the definitions of the picture descriptors of the device pictures of different target devices are unique.

S102, generating a picture name based on the picture descriptor, naming the target picture by the picture name and writing the target picture into a file directory of the equipment center application;

the picture descriptor is used for positioning a target picture to be queried.

It can be understood that, after the target device application corresponding to the target device downloads the device picture of the target device to the file directory corresponding to the target device application from the device cloud of the target device, the device center application reads the target picture corresponding to the target device from the file directory of the target device application, analyzes the target picture to obtain the picture descriptor corresponding to the target picture, then generates a picture name according to the picture descriptor, and stores the target picture in the file directory of the device center application based on the picture name generated by the picture descriptor.

The picture descriptor may include a device model, a device color, a device brand, a picture type, a presentation type, a version number, a picture suffix, and the like, and the picture name may be defined by all the picture descriptors.

Optionally, when the target picture is named by the picture name and written into the file directory of the device center application, a new target folder may be created in the file directory of the device center application, a folder name is generated based on the picture descriptor, and the target picture is stored in the folder named by the folder name by the picture name.

The folder name may be defined by a picture descriptor such as a device model, a device color, a device brand, and the like.

For example, the folder name format may be: ModelId-colorId-brand/. Where modelId is the device model, colorId is the device color, and brand of device. The format of the picture name may be: modelId-colorId-brand _ imageType _ displayType _ version _ suffix. The image type is a picture type, the displayType is a display type, the version is a version number, and the suffix is a picture suffix.

S103, displaying the target picture in the equipment center application.

Specifically, when the target device establishes connection with the terminal for the first time, the target picture is displayed in a UI process corresponding to the device center application; when the target device is not connected with the terminal for the first time, the picture descriptor is obtained based on the device information of the target device, the target picture is positioned from a file directory of the device center application based on the picture descriptor, and the target picture is displayed in a UI process corresponding to the device center application.

It can be understood that, when the target device is not connected to the terminal for the first time, since the target picture of the target device is already stored in the device center application, the picture descriptor is obtained based on the device information of the target device, the target picture is located from the file directory of the device center application based on the picture descriptor, and the target picture is displayed in the UI process corresponding to the device center application, the device information of the target device includes information features, such as a device model, a device color, a device brand, and the like, which are the same as the picture descriptor, the picture descriptor including information, such as a device model, a device color, a device brand, and the like, can be obtained by parsing the device information of the target device, the target picture is located from the file directory of the device center application based on the picture descriptor, and presented in the equipment center application.

It should be understood that the target device establishes a connection with the terminal for the first time and the target device establishes a connection with the terminal for the non-first time, where the target device is not only a single device, but may also refer to multiple devices of the same model and the same appearance, for example: the equipment 1, the equipment 2 and the equipment 3 are three equipment with the same model and the same appearance, the terminal 0 is additionally arranged, at the initial moment, the equipment 1, the equipment 2 and the equipment 3 are never connected with the terminal 0, when the equipment 2 is connected with the terminal for the first time, the equipment application corresponding to the equipment 2 in the terminal downloads the equipment picture of the equipment 2 from the equipment cloud and stores the equipment picture in the file directory of the equipment application, then one of the equipment pictures is read from the file directory of the equipment application and stored in the file directory of the equipment center application as a target picture, and the target picture is displayed in the equipment center application. At this time, if the device 1 or the device 3 establishes connection with the terminal, since the device 1, the device 2, and the device 3 are devices of the same model and the same appearance, the device pictures of the device 1, the device 2, and the device 3 are the same, and at this time, since one device picture of the device 2 has been already stored in the file directory applied to the device center as the target picture, when the device 1 or the device 3 establishes connection with the terminal, the target picture same as the device 2 can be directly used without executing a step of downloading the device picture at the device cloud according to the device information, and transferring the device picture from the file directory applied to the device center to the file directory applied to the device center, so that the amount of operation is reduced, several devices of the same model and the same appearance share one target picture, so that the storage space is saved, and further, the waste of resources is reduced.

In a possible implementation, the locating the target picture from the file directory of the device center application based on the picture descriptor may locate a folder related to the picture descriptor in the file directory of the device center application based on the picture descriptor obtained from the device information of the target device, where a folder name of the folder includes the picture descriptor, and the target picture is stored in the folder.

In a possible implementation manner, the locating the target picture from the file directory of the device center application based on the picture descriptor may be directly locating the target picture in the file directory of the device center application based on a picture descriptor obtained from device information of a target device, where a picture name of the target picture includes the picture descriptor.

Referring to fig. 3, an exemplary schematic diagram of displaying a target picture in a device center application is provided for an embodiment of the present application.

As shown in fig. 3, the device center application displays a plurality of device applications, including connected device applications and unconnected device applications, and displays a device picture of a target device in a display area of each device application.

By adopting the cross-application picture display method provided by the embodiment of the application, the target picture corresponding to the target equipment is firstly read from the file directory applied by the target equipment and is analyzed to obtain the picture descriptor corresponding to the target picture, the picture name is generated based on the picture descriptor, the target picture is named by the picture name and is written into the file directory applied by the equipment center, and finally the target picture is displayed in the equipment center application, so that the equipment pictures of the equipment connected with the terminal can be displayed on the display page applied by the equipment center for managing the equipment connected with the terminal, the equipment pictures of the equipment connected with the terminal can be viewed on the display interface applied by the equipment center without entering the equipment application by a user, and the user experience is improved; and in the storage process of the target picture, a picture descriptor is added to the target picture, the picture descriptor is used for naming the picture, the target picture is classified, and the searching and positioning and the management of the picture resources of the equipment are facilitated when the target picture is used again in the follow-up process.

Referring to fig. 4, a schematic flow chart of a cross-application picture display method is provided in the embodiment of the present application. The execution main body of the embodiment of the application is a terminal. As shown in fig. 4, the cross-application picture presentation method may include the following steps.

It can be understood that, after the target device is connected to and disconnected from the terminal for the first time, the device picture of the target device is already stored in the file directory of the in-terminal device center application. When the target device is connected with the terminal again, because a target picture corresponding to the target device is stored in a file directory of the device center application, the picture descriptor is directly obtained based on the device information of the target device, the target picture is positioned from the file directory of the device center application based on the picture descriptor, and the target picture is displayed in the device center application.

It should be understood that, in the embodiment of the present application, the target device is not limited to only one device, but generally refers to the same model of device with the same appearance. For example, when the headset device 1 is connected to the terminal for the first time, the device picture of the headset device 1 is stored in the file directory of the device center application in the terminal, and the device picture stored in the file directory of the device center application is the target picture, after that, when the headset device 2, the headset device 3, the headset device 4, and the headset device 5 of the same type and appearance as the headset device 1 are connected to the terminal, the picture descriptor of the target picture is obtained based on the device information of the headset device 2, the headset device 3, the headset device 4, and the headset device 5, the target picture is directly located from the file directory of the device center application according to the picture descriptor and displayed in the device center application without downloading the device picture in the cloud according to the device information, and the device picture is transferred from the file directory applied by the device to the file directory applied by the device center, so that the calculation amount is reduced, and several devices with the same type and the same appearance share one target picture, thereby saving the storage space and reducing the waste of resources.

In the embodiment of the application, the device information of the target device is firstly acquired, the device picture corresponding to the target device is downloaded from the cloud to the file directory of the target device application based on the device information, the target picture corresponding to the target device is read from the file directory of the target device application, the target picture and the device information of the target device are analyzed to obtain the picture descriptor corresponding to the target picture, the picture name is generated based on the picture descriptor, the target picture is named by the picture name and written into the file directory of the device center application, and finally the target picture is displayed in the device center application, so that the device pictures of the devices connected with the terminal are displayed on the display page of the device center application for managing the devices connected with the terminal, and a user can view the device pictures of the devices connected with the terminal on the display interface of the device center application without entering the device application The equipment pictures of each equipment improve the user experience; the method comprises the steps of adding a picture descriptor to a target picture in the storage process of the target picture, naming the picture by using the picture descriptor, classifying the target picture, directly searching and positioning in a file directory applied by a device center according to the picture descriptor without performing the step of reading the target picture from the file directory applied by the target device and storing the target picture in the file directory applied by the device center when the target device is not connected with a terminal for the first time, so that the target picture can be read, and the target picture is displayed in the device center application, thereby reducing the operation amount and saving the storage space; and no matter how many device pictures of the target device are downloaded at the cloud, only one of the device pictures is read and stored in the file directory of the device center application, and only one device picture is displayed in the device center application, so that the storage space of a disk and the memory space are saved.

After the target picture is displayed in the device center application, if a developer upgrades a device system or a function of the target device, the device model and/or the version number of the target device may change, so please refer to fig. 5, which provides a flowchart of a cross-application picture display method for another exemplary embodiment of the present application. As shown in fig. 5, the cross-application picture presentation method may include the following steps.

S301, acquiring equipment information of target equipment;
