[0002] With the development of electronic device technology, electronic devices have been integrated into users' lives. When users use an application (APP), the APP often needs to obtain required information. For example, the "map" application needs to obtain location information.

[0003] In the related art, when an application in an electronic device reads data in the electronic device, it needs to perform a polling operation on the database to read data from the database. Since the polling operation needs to repeatedly execute data reading multiple times, the efficiency of reading data in the electronic device is relatively low. Summary of the Invention

[0020] The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order different from those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0022] The terms "at least one (item)", "at least one of", etc. in the specification and claims of the present application refer to any one, any two or more combinations of the included objects. For example, at least one (item) of a, b, and c can represent: "a", "b", "c", "a and b", "a and c", "b and c", and "a, b, and c", where a, b, and c can be single or multiple. Similarly, "at least two (items)" means two or more, and its meaning is similar to that of "at least one (item)".

[0023] The data transmission methods, devices, electronic devices, and readable storage media provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings, through specific embodiments and their application scenarios.

[0024] In a specific application scenario, the data transmission method provided in the embodiments of the present application can be applied to the scenario where a "map" application program obtains location information.

[0025] Exemplarily, when the "Map" application in an electronic device wants to obtain location information, it needs to perform a polling operation on the system database to obtain the location information. At this time, the "Map" application needs to continuously and regularly query the database to check whether location information that meets its requirements has been generated or updated. In this way, the repeated read operations not only consume computing resources but also increase the access pressure on the database, thereby reducing the efficiency of reading data in the electronic device.

[0026] In some other cases, if the "Map" application needs to obtain location information from another application (such as a location service application), it needs to be implemented through the Binder mechanism for inter-process communication. Occupying Binder resources for inter-process data transmission itself consumes a large amount of power. In addition, if the location information is not yet ready in the location service application, the thread used for reading data in the "Map" application needs to be suspended and wait, further increasing resource occupancy and power consumption waste, resulting in low efficiency of data reading in the electronic device.

[0027] In the data transmission method, device, electronic device, and readable storage medium provided in the embodiments of the present application, the "Map" application can declare that it needs to obtain location information through the registration interface of the Information Dispatch Service (IDS), that is, register its corresponding first information type as "location information". Then, the electronic device obtains the information type of the "Map" application (i.e., the first application) as "location information" (i.e., the first information type). After that, according to the information type "location information", the electronic device sends the location information, such as the longitude and latitude information of the current electronic device (i.e., the first information), to the "Map" application through the information distribution interface of the IDS. This longitude and latitude information is the information found by the electronic device from the information cache pool maintained by the IDS or the system database table that matches the information type "location information". In this way, the electronic device can actively send the first information that matches the first information type in the information storage area to the first application through the information distribution interface, without the application performing a polling operation on the system database, thereby improving the efficiency of reading data in the electronic device.

[0028] Next, taking the operating system as an example, an exemplary description is given of the software environment to which the data transmission method provided in the embodiments of the present application is applied.

[0029] As Figure 1 shown, Figure 1 is a schematic diagram of the architecture of a possible operating system provided in the embodiments of the present application. As Figure 1 shown, the architecture of this operating system includes at least four layers, namely: the application layer, the framework layer, the kernel layer, and the hardware layer.

[0030] Among them, the application layer includes various applications in the operating system. For example, Figure 1 APP1 - APP3 in

[0031] The functions of components and processes in each layer are described below.

[0032] Hardware layer: It contains physical hardware devices such as CPU, memory, display screen, touch screen, etc., providing computing, storage, and input / output capabilities, which is the basis for the operation of the entire system.

[0033] Kernel layer: The operating system kernel is responsible for the management and allocation of hardware resources, including process scheduling, memory management, file system, etc.

[0034] Framework layer: It contains system core services and management components, responsible for overall coordination and management of the operation of the application layer and data transmission, etc. Specifically, it includes the following key components:

[0035] Information Registration and Distribution Service (IDS): It provides standard information registration interfaces and information distribution interfaces, allowing applications in the application layer to register and obtain information. The information registration interface enables applications to submit information data generated by themselves, which does not involve user privacy and is not sensitive, to the IDS service so that other applications can use this information, improving the overall consistency and experience of the system. The information distribution interface allows applications to obtain the information types and contents they need from the IDS service.

[0036] It should be noted that the IDS service is an asynchronous service that can distribute information one - to - many. When an application requests to obtain information, if there is no appropriate information type and content in the IDS service, the application can first register to obtain an information listening. When appropriate information becomes available, the IDS service will actively callback or distribute it to the corresponding application process, thus improving the efficiency of information distribution, reducing the number of inter - process communications between applications, and the resource overhead of applications starting threads to query.

[0037] Other framework services: Such as the window management service, which is responsible for managing operations such as the creation, destruction, display, and hiding of application windows, coordinating the switching and layout between application windows; the activity management service, which is used to manage the activity life cycle of applications, ensuring that applications obtain sufficient system resources when running in the foreground, and reasonably recycling resources occupied by background activities; the notification management service, which processes notification messages sent by applications, controlling the display method of notifications and user interaction logic.

[0038] ART Virtual Machine: Provides the runtime environment for the Android operating system and is responsible for executing the bytecode files of applications. When an application is installed, the ART Virtual Machine compiles the bytecode into native machine code, thereby improving the running efficiency and performance of the application. It also provides functions such as memory management, garbage collection, and security detection to ensure that applications run in a stable and secure environment.

[0039] Application layer: Contains various applications that directly interact with users, such as weather applications, map applications, etc.

[0040] Through the above architecture, the operating system can manage and control data transmission in the electronic device.

[0041] The execution subject of the data transmission method provided in the embodiments of the present application can be a data transmission device, and this data transmission device can be an electronic device, or a functional module or functional entity in the electronic device. Hereinafter, taking the electronic device executing the data transmission method as an example, the technical solution provided in the embodiments of the present application will be described.

[0042] Figure 2 For the flowchart of the data transmission method provided in the embodiments of the present application, as Figure 2 shown, the data transmission method provided in the embodiments of the present application may include the following steps 201 to step 202:

[0043] Step 201: The electronic device obtains the first information type corresponding to the first application program.

[0044] Wherein, the above first information type is the information type of the information required by the above first application program

[0045] In some embodiments of the present application, the above first application program may include applications in the system that need to perform data interaction and information acquisition. The first application program may involve multiple aspects such as system services, user interaction, and background data processing, covering various application programs running on the electronic device, such as social applications, map applications, weather applications, etc.

[0046] Exemplarily, the above first application program may be a weather application.

[0047] In some embodiments of the present application, the above first information type may include any one of the following: social type, location type, weather type, system type.

[0048] It should be noted that the above information types may be the data categories required by various applications in the electronic device during operation. These data categories include system status information, user input information, sensor data, network data, etc., covering all information types that the electronic device needs to process and interact with in various application scenarios, such as weather type, network data type, etc.

[0049] Exemplarily, the above first information type may be location information.

[0050] It should be noted that location information is key data required by many applications in specific scenarios. For example, map applications need location information to implement navigation and positioning functions, social applications need location information to implement functions such as location-based check-in, and sports and health applications need location information to record the user's movement trajectory and distance, etc.

[0051] It can be understood that the first information type corresponding to the above first application program may include specific types of data required by the first application program during its operation. The data belonging to the first information type is closely related to the function implementation and business logic of the first application program. The normal operation of the first application program and the provision of services to users require the support of such data.

[0052] For example, the information type obtained by the electronic device for the weather application (i.e., the first application program) is the temperature type (i.e., the first information type). The information type obtained by the electronic device for the map application is the location type. The information type obtained by the electronic device for the social application is the conversation type.

[0053] In some embodiments of the present application, the above electronic device obtaining the first information type corresponding to the first application program may occur when the first application program requests data.

[0054] Exemplarily, when the battery management application needs to update the current real-time remaining battery power of the electronic device, it needs to obtain the remaining battery power information of the electronic device. The electronic device can obtain the information type required by the battery management application as the battery power information type.

[0055] Step 202: The electronic device transmits the first information to the first application program through the information distribution interface according to the first information type.

[0056] Wherein, the above first information is the information in the information storage area of the above electronic device that matches the above first information type; the above information storage area is an information cache pool, or the above information storage area includes a database table.

[0057] In some embodiments of the present application, the above information distribution interface may be a standardized interface provided by IDS, allowing applications to obtain the required data by specifying the information type.

[0058] In some embodiments of the present application, the information distribution interface is designed as an asynchronous service, capable of distributing information one-to-many. When an application requests to obtain information, if the information is temporarily unavailable, the application can register for listening, and the electronic device will actively distribute the information after it becomes available, thereby improving the efficiency and real-time performance of information acquisition.

[0059] Exemplarily, the above first information may be specific longitude and latitude coordinates, such as "116.404013, 39.904211". After the electronic device obtains the type of location information requested by the map application, it will search in the information storage area through the information distribution interface for longitude and latitude information that matches this type. If found, the longitude and latitude coordinate information will be sent to the map application for operations such as map display and navigation.

[0060] Exemplarily again, the above first information may be specific temperature information, such as "26°C".

[0061] Exemplarily again, the above first information may be the remaining battery power information of the electronic device, such as "85%".

[0062] In some embodiments of the present application, the above information cache pool may be an area opened by the system in the memory for temporarily storing information data.

[0063] In some embodiments of the present application, the above database table may be a structured table used by the system for long-term storage of information data. The database table organizes data according to certain rules and relationships, making the storage of data more orderly and facilitating complex data query and management operations.

[0064] It can be understood that when the data in the information cache pool reaches a certain amount or meets specific conditions (such as the information being marked as long-term storage information), the electronic device will synchronize this data from the cache pool to the database table to ensure the persistence and integrity of the data.

[0065] Exemplarily, the electronic device obtains that the information type corresponding to the screen management application program (i.e., the first application program) is the screen brightness type (i.e., the first information type). Then, the electronic device finds the information that matches the screen brightness type, such as "85 nit" (i.e., the first information), from the information storage area according to the screen brightness type. Then, the electronic device actively sends the screen brightness information "85 nit" to the screen management application program through the information distribution interface.

[0066] In this way, the electronic device can actively send the first information that matches the first information type in the information storage area to the first application program through the information distribution interface, without the application program performing a polling operation on the system database, thereby improving the efficiency of reading data in the electronic device.

[0067] In some embodiments of the present application, the information cache pool includes at least one of the following pieces of information:

[0068] Information obtained by the system-level services of the above-mentioned electronic device;

[0069] Information obtained by at least one application in the above-mentioned electronic device.

[0070] In some embodiments of the present application, the information obtained by the above-mentioned system-level services may include information obtained by the electronic device itself, such as sensor data of the device, network status information, battery status information, etc.

[0071] Exemplarily, the information obtained by the above-mentioned system-level services may be the current remaining battery percentage obtained by the battery management module of the device, such as 63%.

[0072] In some embodiments of the present application, the information of the above-mentioned at least one application may include information such as data generated inside the application, data input by the user, and data processed by the application.

[0073] Exemplarily, the information of the above-mentioned at least one application may be new picture data generated after user editing in a picture editing application, or new note content created by the user in a note application.

[0074] In some embodiments of the present application, after the electronic device obtains the first information type corresponding to the first application, it may search for information matching the first information type in the information storage area to obtain the first information that meets the conditions.

[0075] In this way, the electronic device can actively send, through the information distribution interface, the information obtained by the system-level services or the information of the application that matches the first information type in the information storage area to the first application, without the application performing a polling operation on the system database when it needs to obtain system information, or occupying Binder resources to perform inter-process communication with other applications when it needs to obtain the information of other applications, thereby improving the efficiency of reading data in the electronic device.

[0076] In some embodiments of the present application, the above step 202 may include the following steps 202a and 202b:

[0077] Step 202a: The electronic device searches for the first information matching the first information type in the information storage area according to the first information type.

[0078] Step 202b: The electronic device transmits the first information to the first application through the information distribution interface.

[0079] Exemplarily, based on the location information (i.e., the first information type), the electronic device searches in the information storage area (information cache pool or database table) for the first information that matches it. For example, the electronic device finds the latitude and longitude coordinates "116.404013, 39.904211" in the information cache pool. After that, the electronic device sends the found latitude and longitude coordinates "116.404013, 39.904211" to the map application (i.e., the first application) through the information distribution interface, so that it can update the map display or perform navigation calculations.

[0080] In this way, the electronic device can actively send, through the information distribution interface, the information obtained by the system-level service or the information of the application program in the information storage area that matches the first information type to the first application program, without the application program actively searching for the information that matches the information type of the information it needs, thereby improving the efficiency of reading data in the electronic device.

[0081] In some embodiments of the present application, before the above step 201, the data transmission method provided by the embodiments of the present application may further include the following step 203:

[0082] Step 203: The electronic device receives registration information from at least one application program through the information registration interface, and the at least one application program includes the first application program.

[0083] Wherein, one piece of registration information includes at least one of the following:

[0084] The information type requested by an application program to be read;

[0085] The information type that the above application program allows other applications to read;

[0086] The information that the above application program allows other applications to read;

[0087] The application type of other applications that the above application program allows to read information.

[0088] In some embodiments of the present application, the above information registration interface may be a standardized interface provided by IDS, allowing application programs to register information. This interface is designed as an asynchronous service and can receive the information types and contents registered by application programs, so that other applications can obtain this information subsequently.

[0089] In some embodiments of the present application, the information type requested by the above application program to be read may be the information type of the information required by the application program to be obtained.

[0090] Exemplarily, the map application may request to read the location information type in order to obtain the user's current location data during operation.

[0091] In some embodiments of the present application, the type of information that the above application allows other applications to read may be the type of information that the application can provide to other applications to meet the information requirements of other applications.

[0092] Exemplarily, a weather application can provide weather information types for other applications (such as a calendar application, a sports application, etc.) to read weather data, so that other applications can provide richer functions for users in specific scenarios.

[0093] In some embodiments of the present application, the information that the above application allows other applications to read may be the specific information that the application itself can provide to other applications.

[0094] Exemplarily, a battery monitoring application can provide other applications with the battery temperature information of the current electronic device, such as 42°C.

[0095] In some embodiments of the present application, the application type that the above application allows other applications to read information may be the application type of the application that is the specified information reader of the application, that is, the information provided by the application can be read by applications of which application types.

[0096] Exemplarily, for example, the GPS positioning service application of an electronic device can specify that an application of the "map" application type can obtain the location information it provides, that is, the application type allowed to read information is the "map" application type.

[0097] The following combines Figure 3 to exemplarily illustrate the data transmission method provided by the embodiments of the present application.

[0098] As Figure 3 shown, Figure 3 the architecture of the operating system in Figure 3 includes 4 layers, namely: an application layer, a framework layer, a kernel layer, and a hardware layer. Among them, the application layer includes each application in the operating system. For example,

[0099] It should be noted that Figure 3 the arrows marked with numerical labels in

[0100] are used to indicate the steps and order of the data transmission method provided by the embodiments of the present application.

[0101] Exemplarily, step 302: After the information registration and distribution service receives the registration information of APP1, it stores the weather data information in the information cache pool or the system database for matching retrieval and distribution in subsequent processes.

[0102] Exemplarily, step 303: APP2 (such as a calendar application) calls the information distribution interface to request the weather information type data from the information registration and distribution service, aiming to provide the display of the current day's weather on the interface of the calendar application for the user.

[0103] Exemplarily, step 304: After the information registration and distribution service receives the request from APP2, it checks the information cache pool to see if there is information that matches the "weather type". If information that meets the conditions is found, the next step is executed; if not, APP2 is allowed to perform asynchronous registration to implement information listening, and the information will be distributed when it becomes available.

[0104] Exemplarily, step 305: After the information registration and distribution service finds the weather data information registered by APP1 in the information storage area, it sends the information to APP2 through the information distribution interface. After APP2 receives the weather data, it displays it on the interface of the calendar application to provide the current day's weather information for the user.

[0105] In this way, the electronic device receives the registration information from at least one application program through the registration interface in the information registration and distribution service, so that the electronic device can receive the information and information types that the application programs can provide, as well as the information types of the information required by the application programs, so that the electronic device can subsequently actively distribute information to each application program through the information distribution interface, without the application programs actively searching for information that matches the information types they need, thereby improving the efficiency of reading data in the electronic device.

[0106] In some embodiments of the present application, after the above step 203, the data transmission method provided by the embodiments of the present application may further include the following step 204:

[0107] Step 204: The electronic device stores the information in at least one queue in the information cache pool according to the information types that one application program allows other applications to read information.

[0108] Wherein, one queue corresponds to one information type.

[0109] In some embodiments of the present application, the above queue may be a data structure for storing and managing data in a specific order. The queue follows the First In First Out (FIFO) principle, that is, the data that enters the queue earliest will be processed first.

[0110] It can be understood that in the data transmission method provided in the embodiments of the present application, queues are used to classify and store different types of information in the information cache pool, and each queue corresponds to a specific information type, thereby improving the retrieval and distribution efficiency of information.

[0111] Exemplarily, when a weather application registers specific weather-type information (such as "sunny, 25°C, humidity 45%") with the system through an information registration interface, the electronic device stores the specific weather information in the "weather type" queue in the information cache pool according to the information type (weather type). In this way, when other applications (such as a calendar application, a sports application, etc.) request to obtain weather-type data, the system can match the information type required by other applications as the weather type, search for and provide the corresponding information from the "weather type" queue, thereby improving the efficiency and real-time performance of data acquisition.

[0112] Another example is Figure 4 shown, Figure 4 which includes a queue for information type 1, a queue for information type 2, and a queue for information type 3, and the information types of each queue are different. Figure 4 The ellipsis in it indicates that the information cache pool contains not only the three queues shown in the figure, but also other queues not shown. Figure 4 The arrow in it is used to indicate that the electronic device stores the corresponding data in the queue for information type 2. The electronic device can store the information data with the information type of "information type 2" registered by the application program in the queue for information type 2, so that when the information type required by other application programs is "information type 2", the electronic device can search for the information data in this queue and send the information to other application programs through the information distribution interface.

[0113] In this way, the electronic device can store the registration information of the application program in the form of queues in the information cache pool, so that the electronic device can subsequently actively distribute information to each application program through the information distribution interface, without the application program actively searching for information that matches the information type it needs, thereby improving the efficiency of reading data in the electronic device.

[0114] In some embodiments of the present application, after the above step 204, the data transmission method provided in the embodiments of the present application may further include the following step 205:

[0115] Step 205: The electronic device stores at least part of the information stored in at least one queue in a database table.

[0116] In some embodiments of the present application, the above database table may include a structured table for long-term storage of information, which contains multiple fields to record different types of data attributes. For example, for the data in the location information queue, the database table may include fields such as location ID, longitude, latitude, timestamp, etc.; for the data in the weather information queue, it may include fields such as weather ID, location, date, temperature, humidity, wind speed, etc.

[0117] Exemplarily, taking location information as an example, when multiple location data points are accumulated in the location information queue in the information cache pool, or some location information is marked as needing long-term storage, the electronic device will store this location information in the database table. Specifically, information such as the longitude and latitude coordinates and acquisition time of each location data point will be inserted into the location record of the database table one by one.

[0118] Another example is Figure 5 shown Figure 5 including Information Type 1 Queue - Information Type 3 Queue and the database table, where the ellipsis indicates that the information cache pool contains not only the three queues shown in the figure, but also other queues not shown, and the arrow indicates storing the information in the Information Type 2 Queue into the database table. For example, the electronic device can store the information in the Information Type 2 Queue into the database table.

[0119] In this way, the electronic device can store the registration information of the application in the database table for a long time to manage the storage space of the information cache pool or store important information for a long time, so that the storage space of the information cache pool is sufficient and important information is not easily lost, thereby improving the efficiency of reading data in the electronic device.

[0120] Each of the above method embodiments, or various possible implementation manners in each method embodiment, can be executed alone, or, on the premise of no contradiction, can also be executed in combination with each other, which can be specifically determined according to actual usage requirements, and the embodiments of the present application do not limit this.

[0121] The execution subject of the data transmission method provided by the embodiments of the present application can be a data transmission device, and this data transmission device can be an electronic device, or a functional module or functional entity in the electronic device. The following takes the data transmission device executing the data transmission method as an example to illustrate the technical solution provided by the embodiments of the present application.
