Background

Common electronic devices in the market include mobile phones, tablet computers, watches, televisions, man-machine interaction devices on automobiles and the like, and manufacturers of different electronic devices can be different, so that hardware interfaces of different electronic devices can be different. The running of an application requires the invocation of a hardware interface on the electronic device. For example, running a video playback program requires invoking an interface of a display screen and an interface of a microphone on the electronic device. Because the hardware interfaces of different devices can be different, in order to run applications on multiple electronic devices and successfully call related hardware interfaces, an application development company needs to design at least two types of applications to realize that the applications are successfully run on two devices with different hardware interfaces. For example, an application development company needs to design two kinds of applications for a mobile phone and a wristwatch, respectively. The number of mainstream hardware interfaces in the market is large, and an application company needs to design a plurality of different applications for a plurality of hardware interfaces respectively, which can certainly increase the burden of application developers.

The pressure sensor 180A is used for sensing a pressure signal, and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A may be disposed on the display screen 194. The pressure sensor 180A is of various types, such as a resistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, and the like. The capacitive pressure sensor may be a capacitive pressure sensor comprising at least two parallel plates with conductive material. The capacitance between the electrodes changes when a force is applied to the pressure sensor 180A. The electronic device 100 determines the strength of the pressure from the change in capacitance. When a touch operation is applied to the display screen 194, the electronic apparatus 100 detects the touch operation intensity according to the pressure sensor 180A. The electronic device 100 may also calculate the location of the touch based on the detection signal of the pressure sensor 180A. In some embodiments, touch operations that act on the same touch location, but at different touch operation strengths, may correspond to different operation instructions. For example: and executing an instruction for checking the short message when the touch operation with the touch operation intensity smaller than the first pressure threshold acts on the short message application icon. And executing an instruction for newly creating the short message when the touch operation with the touch operation intensity being greater than or equal to the first pressure threshold acts on the short message application icon.

In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., the X, Y, and Z axes) may be determined by gyro sensor 180B. The gyro sensor 180B may be used for photographing anti-shake. For example, when the shutter is pressed, the gyro sensor 180B detects the shake angle of the electronic device 100, calculates the distance to be compensated by the lens module according to the angle, and makes the lens counteract the shake of the electronic device 100 through the reverse motion, so as to realize anti-shake.

The fingerprint sensor 180H is used to collect a fingerprint. The electronic device 100 may utilize the collected fingerprint feature to unlock the fingerprint, access the application lock, photograph the fingerprint, answer the incoming call, etc.

The temperature sensor 180J is for detecting temperature. In some embodiments, the electronic device 100 performs a temperature processing strategy using the temperature detected by the temperature sensor 180J. For example, when the temperature reported by temperature sensor 180J exceeds a threshold, electronic device 100 performs a reduction in the performance of a processor located in the vicinity of temperature sensor 180J in order to reduce power consumption to implement thermal protection. In other embodiments, when the temperature is below another threshold, the electronic device 100 heats the battery 142 to avoid the low temperature causing the electronic device 100 to be abnormally shut down. In other embodiments, when the temperature is below a further threshold, the electronic device 100 performs boosting of the output voltage of the battery 142 to avoid abnormal shutdown caused by low temperatures.

Fig. 2 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present application. The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun rows (Android runtime), and a system library. As shown in fig. 2, each layer in the software architecture may call a hardware layer, which may include a plurality of hardware in fig. 1.

The application layer may include a series of application packages. As shown in fig. 2, the application package may include applications for music playing, video playing, reading applications, application markets, gallery, calendar, conversation, map, navigation, etc.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for applications of the application layer. The application framework layer includes some predefined functions. As shown in fig. 2, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like. The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like. The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc. The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture. The telephony manager is used to provide the communication functions of the electronic device 100. Such as the management of call status (including on, hung-up, etc.). The resource manager provides various resources for the application, such as localization strings, icons, pictures, layout files, video files, and so forth. The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android runtime is responsible for scheduling and management of the android system. The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android. The application layer and the application framework layer run in virtual machines. The virtual machine executes java files of the application layer and the application framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media library (media library), three-dimensional graphics processing library (e.g., openGL ES), 2D graphics engine (e.g., SGL), etc. The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications. Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio video encoding formats, such as: MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc. The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

The hardware layer may include a plurality of hardware, such as the display screen 194, the camera 193, the audio module 170, the sensor module in fig. 1, wherein the sensor module may include, for example, the gyro sensor 180B, the fingerprint sensor 180H, etc. in fig. 1. The application layer, application framework layer, an Zhuoyun rows (Android runtime), and system libraries may each call hardware in the hardware layer by calling a hardware interface. For example, the application layer invokes the display 194 by invoking the display interface.

A hardware interface layer may also be included between the system layer and the hardware layer, the hardware interface layer including a plurality of interfaces for driving the hardware. Such as an interface to drive a display screen, an interface to drive a camera, an interface to drive an audio module, an interface to drive a gyroscopic sensor, an interface to drive a fingerprint sensor, etc.

When a processor or chip inside the electronic device reads the code of an application in the application layer, the hardware in the hardware layer can be driven by calling the hardware interface, and corresponding operations are performed.

In one example, an antenna for mobile communication may be driven by invoking a mobile communication interface, and uplink and downlink communication data may be transmitted through the antenna for mobile communication. For example, when the processor or the chip runs the call application, the code in the call application can be read, so that the mobile communication interface can be called, and the voice call function is realized by driving the antenna for mobile communication.

In one example, the display screen may be driven by invoking a screen display interface and an image may be displayed on the display screen. For example, when the processor or chip runs the video playing application, the code in the video playing application may be read, so that the screen display interface may be invoked and the video played on the display screen.

In one example, a speaker may be driven by invoking a speaker interface and sound may be played through the speaker; or may drive a (externally connected) headset by invoking a headset interface and may play sound through the headset. For example, when running an audio playback application, the processor or chip may read the code in the audio playback application, so that the speaker interface may be invoked and the audio file played through the speaker, or the headphone interface may be invoked and the audio file played through the (externally connected) headphones.

In one example, the fingerprint recognition module may be driven by invoking the fingerprint recognition interface and the fingerprint may be recognized by the fingerprint recognition module. For example, when the processor or the chip runs the security application, the code in the security application can be read, so that the fingerprint identification interface can be called, and when the fingerprint fed back by the fingerprint identification module is matched with the preset fingerprint information, the operation of the current electronic device is considered to be safe.

In one example, a global positioning system (global positioning system, GPS) antenna may be driven by invoking a position location interface and the current location of the electronic device may be determined by the GPS antenna. For example, when the processor or the chip runs the map navigation application, the code in the map navigation application can be read, so that the positioning interface can be called, and the driving path is planned through the positioning information fed back by the GPS antenna.

In one example, a bluetooth antenna may be driven by invoking a wireless communication interface and may receive data from or transmit data to other electronic devices via the bluetooth antenna. For example, when running a file transfer application, the processor or chip may read the code in the file transfer application, so that the wireless communication interface may be invoked and send files to or receive files sent by a nearby electronic device via the bluetooth antenna.

In one example, the camera may be driven by invoking a capture interface and an image or video may be captured by the camera. For example, when the processor or chip runs the photographing application, the code in the photographing application may be read, so that the front-end photographing interface may be called, and the image may be photographed by the front-end camera.

Fig. 3 is a schematic diagram of the architecture of development software for two different types of devices. The types of devices in fig. 3 may include, for example, cell phones, tablet computers, wearable electronic devices with wireless communication capabilities (e.g., smart watches), video player desktop computers, televisions, notebook computers, and the like. For example, the first device in fig. 3 may be a mobile phone, and the second device may be a television.

The hardware interface one of the device one may call the hardware one. The second hardware interface of the second device may call the second hardware. However, for various reasons (for example, the hardware of different devices is usually from different hardware manufacturers, or the design schemes of different electronic devices for the hardware interfaces are different), the hardware interface one is different from the hardware interface two, so that the same program cannot be used to implement the call of the hardware interface one and the call of the hardware interface two. For example, both the display screen of the mobile phone and the screen of the television can be used for playing videos and displaying pictures, however, the display screen of the mobile phone and the screen of the television can be produced by different screen manufacturers, so that the interface of the display screen of the mobile phone is different from the interface of the screen of the television, that is, the same program cannot be used for realizing the calling of the interface of the display screen of the mobile phone and the calling of the interface of the screen of the television.

The system software is typically a program that is installed and loaded on the electronic device by the device manufacturer before the electronic device leaves the factory. Since the hardware interface one of the device one is different from the hardware interface two of the device two, the system software of the device one is different from the system software of the device two.

To facilitate the application developer, device manufacturers typically open a software development kit (software development kit, SDK) to the application developer to facilitate the application developer to develop application software for the device type. The SDK contains code to quickly invoke the hardware interface. Since the hardware interface one of the device one is different from the hardware interface two of the device two, the SDK of the device one is different from the SDK of the device two.

Suppose an application developer wishes to develop a suite of applications, such as video playback software, map navigation software, telephony software, system applications, etc. In order to be able to implement the functionality of the set of applications on both device one and device two (as in fig. 3), two different applications of the same type need to be developed for device one and device two, respectively. For example, video playback software 1 for a mobile phone, and video playback software 2 for a television. Wherein, the two different applications of the same type may refer to the two applications may include an application one for a device one and an application two for a device two, the application one being the same as the application two or having the same main function; however, when the same function or the same main function is implemented, the application one is different from the code, the called interface and/or the function used by the application two, so that the application one cannot be applied to the device two generally, and the application two cannot be applied to the device one generally, and the application one and the application two are two different applications.

Application developers often want applications that most users can use the applications that they develop, so they must compromise the mainstream devices on the market to design application packages for multiple types of devices separately. The application provides a method and aims to improve the convenience of application development.

Fig. 4 is a schematic flowchart of a method for calling a hardware interface according to an embodiment of the present application.

And 401, reading first indication information in a code of a first application, wherein the first indication information is used for indicating related information of a first hardware interface set, the first hardware interface set comprises hardware interfaces of a plurality of electronic devices, and any two hardware interfaces in the first hardware interface set are identical in type or part or all of the functions of any two hardware interfaces in the first hardware interface set are identical.

It will be appreciated that the first application may drive the hardware by code when it invokes the hardware interface, and thus the first set of hardware interfaces may be stored in the processor or memory in the form of code. The hardware interface may implement the hardware call through code, and thus, the hardware interface may be defined using the code. For example, in an android system, a hardware interface may be defined using a hardware interface definition language (HARDWARE INTERFACE definition language, HIDL). For another example, code in java format may be called using the HIDL language to implement the call of the hardware interface.

The electronic device may include a software module or an induration module for identifying the type of device. For example, the electronic device may call the hardware of the electronic device with a version number, model number, etc. of the electronic device.

In general, the hardware interfaces of different types of electronic devices are usually different, for example, the hardware interfaces of a mobile phone are different from the hardware interfaces of a watch, the hardware interfaces of a watch are different from the hardware interfaces of a television, and the hardware interfaces of the mobile phone are different from the hardware interfaces of the television.

The hardware interfaces that different electronic devices of the same type have may be the same or different. For example, the hardware interfaces of two handsets with the same version number may be the same, and the hardware interfaces of two handsets with the same version number may be different.

The electronic device may identify the type of chip, thereby invoking hardware comprising the chip, or determining a hardware interface of hardware comprising the chip. As another example, the electronic device may identify a version number or model of the hardware to determine whether to call the hardware or determine a hardware interface of the hardware.

In one example, any two hardware interfaces in the first set of hardware interfaces are the same type. For example, all hardware interfaces in the first set of hardware interfaces are mobile communication interfaces. For another example, all hardware interfaces in the first set of hardware interfaces are screen display interfaces. As another example, all hardware interfaces in the first set of hardware interfaces are speaker interfaces. As another example, all hardware interfaces in the first set of hardware interfaces are earphone interfaces. As another example, all hardware interfaces in the first set of hardware interfaces are fingerprint identification interfaces. As another example, all hardware interfaces in the first set of hardware interfaces are positioning interfaces. As another example, all hardware interfaces in the first set of hardware interfaces are wireless communication interfaces. As another example, all hardware interfaces in the first set of hardware interfaces are capture interfaces.

In the case that the types of any two hardware interfaces in the first hardware interface set are the same, the type of the first hardware interface set is the same as the type of any one hardware interface in the first hardware interface set. For example, all hardware interfaces in the first set of hardware interfaces are mobile communication interfaces, and the type of the first set of hardware interfaces may be mobile communication interfaces.

Portions of any two hardware interfaces in the first set of hardware interfaces are functionally identical. For example, all hardware interfaces in the first set of hardware interfaces may be used for voice calls, while a first portion of the hardware interfaces in the first set of hardware interfaces may operate in a global system for mobile communications (global system for mobile communications, GSM) system, and a second portion of the hardware interfaces in the first set of hardware interfaces may operate in either a global system for mobile communications (global system for mobile communications, GSM) system or a code division multiple access (code division multiple access, CDMA) system, due to the different mobile communications standards. As another example, all of the first set of hardware interfaces may be used for bluetooth file transfer, while a first portion of the first set of hardware interfaces may be used to drive bluetooth 2.0 and a second portion of the first set of hardware interfaces may be used to drive bluetooth 4.0 due to different wireless communication standards. As another example, all of the hardware interfaces in the first set of hardware interfaces may be used to play audio, while the interface used to play audio includes a speaker interface for driving a speaker and a headphone interface for driving headphones, so that a first portion of the hardware interfaces in the first set of hardware interfaces may be used to drive speakers and a second portion of the hardware interfaces may be used to drive headphones. As another example, all of the hardware interfaces in the first set of hardware interfaces may be used for video input, while the high-definition multimedia interface (high definition multimedia interface, HDMI) may be used for audio input and video input, while the video graphics array (video GRAPHICS ARRAY, VGA) interface is used for video input only, so the first portion of the hardware interfaces in the first set of hardware interfaces may be interfaces used for video input only, and the second portion of the hardware interfaces may be interfaces used for both audio and video input. For another example, all hardware interfaces in the first set of hardware interfaces may be used to capture images or video, while the cameras are further divided into front cameras and rear cameras, so that a first portion of the hardware interfaces in the first set of hardware interfaces may be used to drive the front cameras and a second portion of the hardware interfaces may be used to drive the rear cameras.

In the case that the partial functions of any two hardware interfaces in the first hardware interface set are the same, the functions of the first hardware interface set include the functions of any one hardware interface in the first hardware interface set. For example, all hardware interfaces in the first set of hardware interfaces may be used for voice calls, and the functionality of the first set of hardware interfaces includes voice calls.

All the functions of any two hardware interfaces in the first set of hardware interfaces are identical. For example, all of the first set of hardware interfaces may be used for voice calls and may operate in either a Global System for Mobile communications (global system for mobile communications, GSM) or code division multiple Access (code division multiple access, CDMA) system, and all of the functions performed by any of the first set of hardware interfaces may be performed by other ones of the first set of hardware interfaces. As another example, all hardware interfaces in the first set of hardware interfaces may be used to drive bluetooth 4.0. As another example, all hardware interfaces in the first set of hardware interfaces may be used to play audio and all used to drive headphones. As another example, all hardware interfaces in the first set of hardware interfaces may be used for video input and all may be used for audio input. As another example, all hardware interfaces in the first set of hardware interfaces may be used to capture images or video and all used to drive the front-facing camera.

In the case where all functions of any two hardware interfaces in the first hardware interface set are the same, the functions of the first hardware interface set are the same as those of any one hardware interface in the first hardware interface set. For example, all hardware interfaces in the first set of hardware interfaces may be used for voice calls, the first set of hardware interfaces functioning as voice calls.

Generally, the types of any two hardware interfaces are the same, and the functions that any two hardware interfaces can perform are generally the same or similar.

The first set of hardware interfaces may include a plurality of hardware interfaces of a class of electronic devices. For example, the electronic device comprises a front camera and a rear camera, and the first set of hardware interfaces may comprise a hardware interface 1 for driving the front camera and a hardware interface 2 for driving the rear camera. As another example, the electronic device includes a plurality of multimedia transmission interfaces for supporting different multimedia transmission standards (e.g., HDMI, VGA), respectively.

FIG. 5 is a schematic diagram of hardware interfaces in the first set of hardware interfaces. The first set of hardware interfaces comprises hardware interface 1, hardware interface 2, hardware interface 3, hardware interface 4. The hardware interfaces 1 and 2 are hardware interfaces of the electronic device 501. The hardware interface 3 is a hardware interface provided in the electronic device 502. The hardware interfaces 3 and 4 are hardware interfaces of the electronic device 503.

It can be seen that the hardware interfaces of different electronic devices may be identical. For example, the mobile phone 1 with version number 1 uses the hardware 1, the mobile phone 2 with version number 2 uses the hardware 2, the hardware 1 and the hardware 2 are from the same hardware manufacturer, and the hardware 1 and the hardware 2 are the same model of hardware, so the mobile phone 1 and the mobile phone 2 can have the same hardware interface.

According to the above description, the first set of hardware interfaces may include a plurality of hardware interfaces of the same type, and include hardware interfaces of a plurality of electronic devices. Taking fig. 5as an example, the hardware interface 1, the hardware interface 2, the hardware interface 3, and the hardware interface 4 may be shooting interfaces, the electronic device 501 may be a mobile phone, the electronic device 502 may be a watch, and the electronic device 503 may be a tablet computer. The hardware interface 1 of the electronic device 501 may be a photographing interface for calling a front camera, and the hardware interface 2 of the electronic device 501 may be a photographing interface for calling a rear camera. The hardware interface 3 of the electronic device 503 may be a photographing interface for calling a front camera, and the hardware interface 4 of the electronic device 503 may be a photographing interface for calling a rear camera. The hardware interface 3 of the electronic device 502 is the same as the hardware interface 3 of the electronic device 503. Similarly, according to the description above, the first set of hardware interfaces may include a plurality of hardware interfaces that are partially or fully functionally identical, and include hardware interfaces of a plurality of electronic devices.

Optionally, the first indication information includes information indicating a second hardware interface, and the electronic device does not have the second hardware interface, and before determining at least one first hardware interface of the electronic device from the first hardware interface set according to the first indication information, the method further includes: and determining a hardware interface set to which the second hardware interface belongs as the first hardware interface set according to the first indication information.

The electronic device may store information related to the first set of hardware interfaces including an identification of the first set of hardware interfaces and information (e.g., an identification of each hardware interface, a call parameter, etc.) of a plurality of hardware interfaces in the first set of hardware interfaces including the second hardware interface. For example, the identifier of the first hardware interface set shown in fig. 5, the identifier of the hardware interface 1, the identifier of the hardware interface 2, the identifier of the hardware interface 3, the identifier of the hardware interface 4, and the correspondence relationship between the first hardware interface set and the hardware interface 1, the hardware interface 2, the hardware interface 3, and the hardware interface 4, respectively, may be saved. When the electronic device 501 reads the first indication information in the code of the first application and the first indication information indicates the hardware interface 3 in fig. 5, since the electronic device 501 does not have the hardware interface 3, the electronic device 501 cannot call the hardware interface 3, and the electronic device 501 may determine that a correspondence exists between the hardware interface 3 and the first hardware interface set according to the first indication information and the related information of the first hardware interface set, so as to determine the first hardware interface set.

FIG. 6 is a schematic diagram of a plurality of hardware interface sets. The electronic device may store information about a plurality of hardware interface sets including the hardware interface set 601 and the hardware interface set 602 shown in fig. 6.

In one example, the type of the set of hardware interfaces 601 is type 1 and the type of the set of hardware interfaces 602 is type 2.

The first indication information includes information indicating a first type of hardware interface that the first application needs to call, and before determining at least one first hardware interface of the electronic device from the first hardware interface set according to the first indication information, the method further includes: and determining the hardware interface set matched with the first type as the first hardware interface set according to the first indication information.

The first set of hardware interfaces matches a first type, which is a possible case. The types of hardware interface sets have been described in detail above and will not be described in detail here.

Another possibility is that the functionality of the first set of hardware interfaces is the same or similar to the functionality implemented by the first type.

For example, the type indicated by the first indication information is a mobile communication interface, and the functions of the first set of hardware interfaces include a voice call function, which can also be implemented by the mobile communication interface, so that the first set of hardware interfaces matches the first type.

As another example, the type indicated by the first indication information is a screen display interface, the function of the first set of hardware interfaces includes a function of displaying an image on a screen, and the screen display interface is also capable of implementing the function of displaying an image on a screen, so that the first set of hardware interfaces matches the first type.

As another example, the type indicated by the first indication information is a speaker interface, and the function of the first set of hardware interfaces includes a sound playing function, and the speaker interface is also capable of implementing the sound playing function, so that the first set of hardware interfaces matches the first type.

As another example, the type indicated by the first indication information is an earphone interface, and the function of the first hardware interface set includes a sound playing function, and the earphone interface can also implement the sound playing function, so that the first hardware interface set is matched with the first type.

For another example, the type indicated by the first indication information is a fingerprint identification interface, and the functions of the first hardware interface set include fingerprint identification functions, and the fingerprint identification interface can also implement the fingerprint identification functions, so that the first hardware interface set is matched with the first type.

As another example, the type indicated by the first indication information is a positioning interface, and the functions of the first set of hardware interfaces include a positioning function, and the positioning interface is also capable of implementing the positioning function, so that the first set of hardware interfaces matches the first type.

As another example, the type indicated by the first indication information is a wireless communication interface, and the function of the first set of hardware interfaces includes a data transmission function, and the wireless communication interface is also capable of implementing the data transmission function, so that the first set of hardware interfaces matches the first type.

For another example, the type indicated by the first indication information is a shooting interface, and the functions of the first hardware interface set include capturing a scene around the electronic device, and the shooting interface can also implement the function of capturing the scene around the electronic device, so that the first hardware interface set is matched with the first type.

Thus, in the event that the first application indicates to invoke a first type of hardware interface via the first indication information, the electronic device may determine the first set of hardware interfaces matching the first type based on the first type.

Fig. 10 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present application. The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun rows (Android runtime), and a system library. As shown in fig. 9, each layer in the software architecture may call a hardware layer through a hardware interface layer, which may include a plurality of hardware in fig. 1. The application layer, the application framework layer, an Zhuoyun rows (Android runtime), the system library and the hardware layer may refer to the example shown in fig. 2, and are not described herein.

A hardware interface layer may also be included between the system layer and the hardware layer, the hardware interface layer including hardware interfaces of a plurality of electronic devices, each hardware interface capable of driving hardware of one electronic device. Including for example a cell phone interface for driving a display, a watch interface for driving a display, a television interface for driving a display, a cell phone interface for driving a camera, etc.

When a processor or a chip in the electronic equipment reads codes of an application program layer, an application framework layer, an Zhuoyun rows and a system library, a hardware interface which can be called by the electronic equipment can be found through a hardware interface layer, so that hardware in the hardware layer is driven, and corresponding operations are executed. For example, the hardware interface layer includes hardware that can be called by the mobile phone, hardware that can be called by the watch, and hardware that can be called by the television, and the mobile phone can find a hardware interface that can be called by the mobile phone in the hardware interface layer, so as to drive the hardware in the hardware layer and execute corresponding operations.

Fig. 11 is a block diagram showing an internal structure of a hardware interface layer. The hardware interface layer may include a hardware interface agent layer, a hardware interface adaptation layer, and a hardware interface access control layer.

The hardware interface agent layer may include a rights control for confirming whether the hardware interface access request is secure or not, and may also be used for confirming whether the access object has rights to access the hardware interface or not. The hardware interface agent layer can realize safe and reasonable access to the hardware interface layer.

The hardware interface adaptation layer includes a plurality of hardware interfaces. The hardware interface may implement the hardware call through code, and thus, the hardware interface may be defined using the code. For example, in an android system, a hardware interface may be defined using a hardware interface definition language (HARDWARE INTERFACE definition language, HIDL). For another example, code in java format may be called using the HIDL language to implement the call of the hardware interface.

The plurality of hardware interfaces are of different types from each other. Or the hardware interface adaptation layer comprises the plurality of hardware interfaces, and functions which can be realized by the plurality of hardware interfaces are different from each other. Fig. 11 shows an example in which the hardware interface adaptation layer includes a plurality of different types of hardware interfaces. As shown in fig. 11, the hardware interface adaptation layer includes a type 1 hardware interface and a type 2 hardware interface. The plurality of hardware interfaces in the hardware interface adaptation layer are virtual interfaces.

The electronic device may include a software module or an induration module for identifying the type of device. For example, the electronic device may call the hardware of the electronic device or determine the hardware interface of the electronic device by the version number, model number, etc. of the electronic device. The electronic device may include a software module or an induration module for identifying the type of hardware. For example, the electronic device may identify the type of chip, thereby invoking hardware comprising the chip, or determining a hardware interface of hardware comprising the chip. As another example, the electronic device may identify a version number or model of the hardware to determine whether to call the hardware or determine a hardware interface of the hardware.

As shown in fig. 11, the hardware interface of type 1 corresponds to the hardware interface 1 of the device 1, the hardware interface 2 of the device 2, and the hardware interface 3 of the device 3. The hardware interface of the type 2 has a corresponding relation with the hardware interface 4 of the device 1 and the hardware interface 5 of the device 2. When there is an instruction by the application program to call the hardware interface of the type 1 through the instruction information, the device 1 may call the hardware interface 1 according to the instruction information. And when the application program indicates to call the hardware interface of the type 2 through the indication information, the device 3 can call a preset target interface or present alarm information. The plurality of hardware interfaces in the hardware interface access control layer may be used to represent the plurality of hardware interfaces in the set of hardware interfaces above.
