Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
It should be noted that the terms "first", "second", and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. Additionally, the term "and/or," which describes an associative relationship of associated objects, means that there may be three relationships, e.g., A and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. The step numbers in the present application are only for example, and may correspond to different embodiments, and the order thereof is not limited in the case of no conflict. Technical features in the examples and embodiments provided in the present application may be combined with each other without conflict.
In practical applications, a large enterprise or a manufacturer wants to use an on/off display object of an electronic device such as a computer or a mobile phone, for example, an on/off Logo, an on/off animation, etc., of the manufacturer, but cannot keep a mark related to the manufacturer.
However, the native android system of the electronic device only supports switching of wallpapers at present, and there is no corresponding switching method for the power on/off Logo and the power on/off animation. In particular, the Logo displayed when the electronic device is powered on is loaded before the file system is initialized, and therefore cannot be managed by the file system, and it is difficult to support dynamic loading. In practical application, if the boot Logo needs to be changed, only a series of processes such as revising the system code, recompiling, reissuing the system version, reentering the factory or flashing the channel dealer can be performed.
Based on this, the application provides a data processing method, a data processing device, an electronic device and a storage medium, which can dynamically switch the on/off display object of the electronic device, and improve the convenience of switching the on/off display object.
The data processing method provided by the embodiment of the present application may be applied to the system architecture 100 shown in fig. 1. As shown in fig. 1, the system architecture provided by the embodiment of the present application includes a terminal 110 and a server 120, where the terminal 110 (illustratively, the terminal 110-1 and the terminal 110-2) is connected to the server 120 through a network 130, and the network 130 may be a wide area network or a local area network, or a combination of both.
In some embodiments, the terminal 110 may be a laptop computer, a tablet computer, a desktop computer, a set-top box, a mobile device (e.g., a mobile phone, a portable music player, a personal digital assistant, a dedicated messaging device, a portable gaming device), and the like. The terminal 110 may include a graphical display interface 111, and the terminal 110 may display an on/off Logo, an on/off animation, or the like on the graphical display interface 111 each time the terminal is turned on or off.
In some embodiments, the server 120 may be an independent physical server, may also be a server cluster or a distributed system formed by a plurality of physical servers, and may also be a cloud server providing basic cloud computing services such as cloud services, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, middleware services, a domain name service, a security service, and a big data and artificial intelligence platform. The terminal 110 and the server 120 may be directly or indirectly connected through wired or wireless communication, and the embodiment of the disclosure is not limited thereto.
Next, a data processing method provided in the embodiment of the present application is described with reference to a system architecture shown in fig. 1.
An embodiment of the present application provides a data processing method, which is applied to a first electronic device. The first electronic device may be the terminal 110-1 or the terminal 110-2 shown in fig. 1. Referring to the schematic flow chart of the data processing method shown in fig. 2, the data processing method provided in the embodiment of the present application may include the following steps:
Here, the multimedia data refers to image data, audio data, video data, and the like that can be an object of the on/off display of the first electronic device.
In this embodiment of the present application, the multimedia data may be uploaded by a user or sent by other electronic devices, and a source of the multimedia data is not limited in this embodiment of the present application.
Further, after the multimedia data is acquired by the first electronic device, the multimedia data may be stored in a target memory partition of the first electronic device.
Specifically, the hard disk storage space of the first electronic device may be divided into a plurality of independent areas for storing different types of files, such as an operating system, an application program, and a data file.
The target storage partition mentioned in the embodiment of the present application is a newly added partition, and is dedicated to storing the multimedia data. Here, the target storage partition may be initialized before a file system in the first electronic device is initialized. That is, the target storage partition is already available for storing and reading data before the file system initialization of the first electronic device is completed, and the file reading of the target storage partition is not affected by the file system.
Therefore, after the multimedia data is stored in the target storage partition, the first electronic device can read the stored multimedia data in the target storage partition, load the multimedia data and use the multimedia data as a startup and shutdown display object before the file system is initialized in the next startup and power-on process.
Here, since the target storage partition is not affected by the file system, the target storage partition can be used for reading data after the electronic device is powered on. Thus, the target memory partition may be used for access to on/off display objects.
Specifically, before the first electronic device is powered on and starts up and loads the on/off display object, the identification information may be read first, and it is determined whether the on/off display object needs to be switched.
Here, the identification information may be stored in the above-described target storage partition. Therefore, after the first electronic device is powered on and started and before the file system is not initialized, the identification information can be directly read from the target storage partition, so that whether the switching on and off display object needs to be switched to the multimedia data stored in the target storage partition or not is judged. Therefore, the first electronic equipment immediately completes the switching of the on-off display object after being turned on.
And 203, if the identification information represents that the on-off display object needs to be replaced by the multimedia data, loading and displaying the multimedia data stored in the target storage area.
In this embodiment of the application, if the identification information indicates that the on/off display object of the first electronic device needs to be switched, the multimedia data in the target storage partition is directly read, and the multimedia data is displayed in the on/off process. And if the identification information indicates that the on-off display object of the first electronic equipment does not need to be switched, loading data corresponding to the original on-off display object.
For example, the identification information may be one-bit type data, and when the value of the identification information is 1, it may indicate that the target storage partition stores multimedia data and needs to be displayed as a power on/off display object, and when the value of the identification information is 0, it may indicate that the target storage partition does not store multimedia data, that is, it is not necessary to switch the power on/off display object.
To sum up, the data processing method provided in the embodiment of the present application may store the acquired multimedia data in the target storage partition that has been initialized before the file system is initialized; in addition, in the process of power-on starting and/or power-off of the first electronic equipment and before loading the on-off display object, acquiring identification information, and determining whether the on-off display object needs to be replaced by multimedia data stored in the target storage partition based on the identification information; and if the identification information represents that the on-off display object needs to be replaced by the multimedia data, loading and displaying the multimedia data stored in the target storage area. Therefore, the first electronic device can determine whether to switch the on-off display object to the multimedia data according to the identification information before the on-off display object is loaded, and can directly read the multimedia data from the target storage partition to load the multimedia data if the on-off display object needs to be switched to the multimedia data. Therefore, the on-off display object of the electronic equipment can be switched, and convenience in switching the on-off display object is improved.
In an embodiment of the present application, referring to the flowchart shown in fig. 3, before the step 201 acquires the multimedia data, the following steps may be further performed:
wherein the target storage partition does not contain a file system, such that the target storage partition completes an initialization process prior to initializing the file system.
In the embodiment of the application, when the function of switching the on/off display object of the first electronic device needs to be implemented, a target storage partition not containing a file system may be created in the first electronic device. Partitions that do not contain a file system may also be referred to as bare areas.
Because the target storage partition does not contain the file system, the initialization process of the target storage partition is very quick, and the target storage partition can complete the initialization process before the file system is initialized.
Based on this, the data processing method provided by the embodiment of the present application can store multimedia data in the target storage partition. In this way, the first electronic device can read the multimedia data in the target storage partition in the early process of power-on start. Therefore, storage guarantee is provided for the switching function of the on-off display object of the first electronic equipment.
In an embodiment of the present application, the target storage partition may be structured in a customized manner. In particular, the target storage partition may be divided into an identification storage area, and a data storage area. The identification storage area is used for storing identification information, and the data storage area is used for storing multimedia data.
Correspondingly, the identification information obtained in step 202 may be implemented in the following manner:
the first electronic equipment acquires the stored identification information from the identification storage area;
in addition, the loading of the multimedia data stored in the target storage partition in step 203 can be implemented by:
the first electronic device reads and loads the multimedia data from the data storage area.
That is, each time the first electronic device is powered on, the first electronic device may first obtain the identification information from the identification storage area in the target storage partition. And according to the indication of the identification information, determining whether multimedia data needs to be read from the data storage area in the target storage partition for loading.
Specifically, if the identification information indicates that the on/off display object of the first electronic device needs to be switched, the first electronic device obtains the stored multimedia data from the data storage area in the target storage partition, and displays the multimedia data in the on/off process. And if the identification information indicates that the on-off display object of the first electronic equipment does not need to be switched, loading data corresponding to the original on-off display object.
In the embodiment of the present application, the identification information may be only one bit of data, and thus the reading is simple and fast. The first electronic device may determine whether to read the multimedia data according to the indication of the identification information. Therefore, the reading efficiency of the multimedia data can be improved.
Based on the foregoing embodiment, in an embodiment of the present application, referring to the flowchart shown in fig. 4, the step 201 of acquiring multimedia data may be implemented by:
In an embodiment of the present application, the second electronic device may be the server 120 in the system architecture shown in fig. 1. The first electronic device may be connected to the second electronic device through a preset network. Here, the default network may be a cellular network, a Wireless Fidelity (WiFi) network, a bluetooth network, and the like, and the type of the network is not limited in this embodiment of the application.
Specifically, the first electronic device may send request information to the second electronic device through the preset network to request the second electronic device to send multimedia data to the second electronic device. After receiving the request message, the second electronic device may also feed back the requested multimedia data to the first electronic device through the predetermined network.
In one possible implementation, the first electronic device may send request information to the second electronic device to request multimedia data according to a time period.
The second electronic device may receive the request information sent by the plurality of first electronic devices, and process the request information sent by the plurality of first electronic devices. Meanwhile, the second electronic device may also feed back the multimedia data to a plurality of first electronic devices at the same time.
Therefore, when the on-off display objects of the plurality of first electronic devices need to be switched in batch, the multimedia data only need to be uploaded to the second electronic device. After the first electronic equipment is started and networked with the second electronic equipment, the multimedia data are sent to the plurality of first electronic equipment, so that the switching of the on-off display objects of the plurality of first electronic equipment is realized. Therefore, one-button modification of the on-off display objects of the first electronic equipment can be achieved at the cloud, and convenience of the on-off display objects of the electronic equipment is improved.
In an embodiment of the present application, the acquiring of the multimedia data in step 201 and storing the multimedia data in the target storage partition may be implemented by the following steps:
step 2013, the first electronic device obtains multimedia data by using the first application;
step 2014, the first electronic device controls the first application to send multimedia data to the framework layer through the first interface in the application layer;
step 2015, the first electronic device sends the multimedia data to the kernel layer through the second interface on the framework layer;
step 2016, the first electronic device writes the multimedia data into the target storage partition through the third interface in the kernel layer.
It is understood that the first electronic device may manage multimedia data through a first application of a higher layer. For example, the first electronic device may download multimedia data from the second electronic device through the first application, or obtain multimedia data input by a user. In addition, the first electronic device may further read, by the first application, data stored in the target storage partition, delete multimedia data in the target storage partition, and the like.
Specifically, when the target storage partition is created, a plurality of interfaces may be added at the same time, and the interfaces may be connected to an application layer, a framework (frame) layer, and a kernel (kernel) layer, respectively. After the first application in the high-level application layer acquires the multimedia data, the multimedia data can be stored in the target storage partition of the hardware structure through the first interface, the second interface and the third interface. Therefore, the data processing method provided by the embodiment of the application can be automatically completed by controlling the data reading process through the high-level application.
Based on the foregoing embodiment, in an embodiment of the present application, before the first electronic device acquires the multimedia data by using the first application in step 2013, the following steps may be further performed:
acquiring an authority configuration instruction;
and responding to the authority configuration instruction, and setting the access authority of the target storage partition so that the first application has the authority of accessing the target storage partition.
In the embodiment of the application, the target storage partition is a newly added hardware storage partition. Since the target storage partition is limited by a Security-Enhanced Linux (SeLinux), the external application cannot read the newly added storage partition at will.
Based on this, after the target storage partition is created, the authority of the partition needs to be configured, so that the application responsible for reading and writing and the application responsible for Logo loading have the right to access the target storage partition.
Here, the first electronic device may obtain an authority configuration instruction input by a user, and configure the authority of the target storage partition based on the authority configuration instruction, so that the first application may read data in the target storage partition.
In summary, the data processing method provided in the embodiment of the present application can read multimedia data from the created target storage partition without the file system as the on/off display object before the file system is not loaded, so as to implement switching of the on/off display object; the convenience of switching the on-off display object is improved.
Another embodiment of the present application provides a data processing method, which can be applied to a second electronic device. The second electronic device is understood to be a management device that can modify the on/off display objects in the plurality of first electronic devices. The first electronic device may be the server 120 in the system architecture shown in fig. 1.
Referring to a schematic flow chart of a data processing method shown in fig. 5, a data processing method provided in an embodiment of the present application may include the following steps:
Here, the multimedia data may be image data, audio data, video data, and the like uploaded by the user. In the embodiment of the application, the second electronic device may obtain the file with the format png uploaded by the user, and convert the file with the data type png into a file with a bin or img format for storage by using a conversion tool. The file with the bin format is a binary file, and the file with the img format is stored in a two-dimensional array format, so that the file with the bin or img format can be read without decoding, and the loading speed of data is increased.
the target storage partition is a storage area which is initialized before the file system is initialized.
In this embodiment of the application, the second electronic device may be connected to the plurality of first electronic devices through a preset network. The preset network may be a cellular network, a WiFi network, a bluetooth network, etc., and the embodiment of the present application is not limited to the type of the network.
Here, the second electronic device may transmit multimedia data to the at least one first electronic device through a preset network. After the first electronic device receives the media data, the multimedia data can be stored in the newly created target storage partition. The target storage partition may be initialized prior to file system initialization in the first electronic device. That is, the target storage partition is already available for storing and reading data before the file system initialization of the first electronic device is completed, and the file reading of the target storage partition is not affected by the file system.
Therefore, after the first electronic device is powered on and started and before the file system is not initialized, the first electronic device can directly read the identification information from the target storage partition, so as to determine whether the switching of the power-on and power-off display object to the multimedia data stored in the target storage partition is needed. Therefore, the first electronic equipment immediately completes the switching of the on-off display object after being turned on.
In the embodiments provided in the present application, the second electronic device may also send the multimedia data to a plurality of first electronic devices at the same time. When the on-off display objects of the electronic equipment need to be switched in batches, the multimedia data only need to be uploaded to the second electronic equipment. After the first electronic equipment is started and connected with the second electronic equipment, the second electronic equipment can send the multimedia data to all the first electronic equipment. Therefore, one-button modification of the on-off display objects of all the first electronic equipment can be achieved at the cloud, and convenience of the on-off display objects of the electronic equipment is improved.
In an embodiment of the present application, the second electronic device may divide the related management authority according to a user role of the first electronic device. For example, if the user role of the first electronic device is an administrator, the first electronic device may not only download the multimedia data, but also modify the multimedia data in the second electronic device. If the user role of the first electronic device is a common user, the first electronic device can only download the multimedia data stored in the second electronic device,
based on the foregoing embodiments, in the embodiments provided in this application, the sending of the multimedia data to the at least one first electronic device in step 502 may be implemented by:
step 5021, receiving request information sent by at least one first electronic device, wherein the request information is used for requesting multimedia data;
step 5022, multimedia data are sent to at least one first electronic device.
It is understood that the second electronic device may transmit the multimedia data to the first electronic device after the first electronic device requests the multimedia data.
In an embodiment of the application, the request information may include version information of multimedia data currently stored by the first electronic device.
Correspondingly, the step 5022 of sending the multimedia data to at least one first electronic device can be implemented by the following steps:
judging whether the version information sent by the target first electronic equipment is matched with the version information of the latest multimedia data; the target first electronic device is any one of at least one first electronic device;
and if the version information sent by the target first electronic equipment does not match with the latest version information of the multimedia data, sending the multimedia data to the target first electronic equipment.
In the embodiment of the application, in order to prevent the multimedia data from being repeatedly transmitted, when the first electronic device requests information from the second electronic device transmitter, the version information of the multimedia data may be carried in the request information.
After receiving the request information, the second electronic device may analyze the request information to obtain version information of the multimedia data in the first electronic device that sent the request information, so as to determine whether the multimedia data stored in the first electronic device is the latest.
Further, if the multimedia data in the first electronic device is determined to be the latest, the second electronic device does not send the multimedia data to the first electronic device any more. And if the multimedia data in the first electronic equipment is judged not to be latest, the latest multimedia data is sent to the first electronic equipment. Therefore, the repeated transmission of the multimedia data can be prevented, and the network resources are saved.
An embodiment of the present application provides a data processing method, and referring to the flowchart shown in fig. 6, the data processing method may include the following steps:
step 610, the first electronic device creates a target storage partition.
In the embodiment of the application, the target storage partition is a partition without a file system.
Step 620, the first electronic device sends request information to the second electronic device; the request information is used to request multimedia data.
Step 630, the second electronic device sends the multimedia data to the first electronic device.
And step 640, the first electronic device receives the multimedia data and stores the multimedia data in the target storage partition.
Step 650, during the power-on start and/or power-off process of the first electronic device, and before loading the power-on and power-off display object, acquiring the identification information, and determining whether the power-on and power-off display object needs to be replaced by the multimedia data stored in the target storage partition based on the identification information.
And 660, if the identification information represents that the on-off display object needs to be replaced by the multimedia data, the first electronic equipment loads and displays the multimedia data stored in the target storage area.
