Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

A mobile terminal implementing various embodiments of the present invention will now be described with reference to fig. 1. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.

The mobile terminal may be implemented in various forms. For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a Personal Digital Assistant (PDA), a tablet computer (PAD), a Portable Multimedia Player (PMP), a navigation device, etc., and a stationary terminal such as a digital TV, a desktop computer, etc. In the following, it is assumed that the terminal is a mobile terminal. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for moving purposes.

Fig. 1 is a schematic hardware structure of an optional mobile terminal for implementing various embodiments of the present invention.

The mobile terminal 100 may include a wireless communication unit 110, a user input unit 130, an output unit 150, a memory 160, an interface unit 170, a controller 180, and a power supply unit 190, etc. Fig. 1 illustrates a mobile terminal having various components, but it is to be understood that not all illustrated components are required to be implemented, and that more or fewer components may instead be implemented, the elements of the mobile terminal being described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit may include at least one of a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, and a location information module 115.

The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast management server via a broadcast channel. The broadcast channel may include a satellite channel and/or a terrestrial channel. The broadcast management server may be a server that generates and transmits a broadcast signal and/or broadcast associated information or a server that receives a previously generated broadcast signal and/or broadcast associated information and transmits it to a terminal. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and the like. Also, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. The broadcast associated information may also be provided via a mobile communication network, and in this case, the broadcast associated information may be received by the mobile communication module 112. The broadcast signal may exist in various forms, for example, it may exist in the form of an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of digital video broadcasting-handheld (DVB-H), and the like. The broadcast receiving module 111 may receive a signal broadcast by using various types of broadcasting systems. In particular, the broadcast receiving module 111 may receive digital broadcasting by using a digital broadcasting system such as a data broadcasting system of multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), forward link media (MediaFLO @), terrestrial digital broadcasting integrated service (ISDB-T), and the like. The broadcast receiving module 111 may be constructed to be suitable for various broadcasting systems that provide broadcast signals as well as the above-mentioned digital broadcasting systems. The broadcast signal and/or broadcast associated information received via the broadcast receiving module 111 may be stored in the memory 160 (or other type of storage medium).

The mobile communication module 112 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.

The wireless internet module 113 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal. The wireless internet access technology to which the module relates may include WLAN (wireless LAN) (Wi-Fi), Wibro (wireless broadband), Wimax (worldwide interoperability for microwave access), HSDPA (high speed downlink packet access), and the like.

The short-range communication module 114 is a module for supporting short-range communication. Some examples of short-range communication technologies include bluetooth^TMRadio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee^TMAnd so on.

The location information module 115 is a module for checking or acquiring location information of the mobile terminal. A typical example of the location information module 115 is a GPS (global positioning system). According to the current technology, the GPS module 115 calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the GPS module 115 can calculate speed information by continuously calculating current position information in real time.

The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151 and the like.

The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.

Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or will be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The memory 160 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 181 for reproducing (or playing back) multimedia data, and the multimedia module 181 may be constructed within the controller 180 or may be constructed separately from the controller 180. The controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

The various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or any combination thereof. For a hardware implementation, the embodiments described herein may be implemented using at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a processor, a controller, a microcontroller, a microprocessor, an electronic unit designed to perform the functions described herein, and in some cases, such embodiments may be implemented in the controller 180. For a software implementation, the implementation such as a process or a function may be implemented with a separate software module that allows performing at least one function or operation. The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in the memory 160 and executed by the controller 180.

Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

Based on the hardware structure of the mobile terminal, the invention provides various embodiments of the method.

Example one

Referring to fig. 2, which illustrates a method for cleaning a background application according to an embodiment of the present invention, the method may be applied to a terminal having at least a dual-screen display, and the method may include:

s201: the terminal respectively acquires currently started application programs of a first screen and a second screen;

it should be noted that, in the embodiment of the present invention, the first screen and the second screen are two different entity screens on the same terminal, and are not two sub-screens of the same screen in the split-screen state; the first screen and the second screen can be arranged at different positions of the terminal according to actual needs, and generally, for a folding type terminal, the first screen and the second screen can be arranged at two sides of the folding type terminal; for a bar-type terminal, the first screen and the second screen may be respectively disposed on two sides of the terminal, which is not described in this embodiment.

S202: when a preset first operation instruction is received in a display area of a first screen, calling a currently opened application program list of a second screen in the display area of the first screen by a terminal;

s203: and the first screen receives a second operation instruction aiming at the application program list currently opened by the second screen, and cleans the application program currently opened by the second screen according to the second operation instruction.

It should be noted that, according to the above technical scheme, if a running pause phenomenon occurs in the use process of the first screen, the terminal can perform a cleaning operation on the application program started in the second screen in the first screen, so that the background application program is cleaned by taking the screen as a unit, and the running of the application program in the first screen is not affected after the background application program is cleaned.

For example, the cleaning the application currently opened on the second screen according to the second operation instruction in step S203 may specifically include:

cleaning all application programs currently started on a second screen according to the second operation instruction;

or clearing the application program indicated by the second operation instruction from the currently opened application program of the second screen.

It should be noted that, for cleaning of the background application program, two manners of all cleaning and selective cleaning may be included, and correspondingly, the second operation instruction may also correspondingly include all cleaning instructions and selective cleaning instructions. As can be understood, when the second operation instruction corresponds to all the cleaning instructions, the terminal cleans all the application programs currently started on the second screen; when the second operation instruction corresponds to the selection cleaning instruction, the terminal only cleans the application programs which are started in the second screen and are indicated by the second operation instruction.

Preferably, for step S202, it should be noted that the first operation instruction is used to instruct a user to perform an operation on the terminal, and specifically, when a running stuck phenomenon occurs during a process of using the first screen by the user or when the user needs to actively clean the background application program by himself/herself, the user performs the first operation on the terminal to enable the terminal to receive the corresponding first operation instruction;

in a specific implementation process, the first operation instruction may include a single operation or a combination of multiple operations for the terminal, for example, a user may cause a currently-opened application list of the second screen to be called out in a display area of the first screen by long-pressing a menu key in the first screen; or the user can call out the application program list currently opened by the second screen in the display area of the first screen by long pressing the home key and the return key. The specific implementation form of the operation instruction may be different according to different application scenarios, and details are not described in this embodiment. Only the operation corresponding to the first operation instruction is required to be free from conflict with the existing operation of the terminal operation system.

Exemplarily, the technical solution of this embodiment may also call up a self-started application list in the first screen, and may include:

when a preset third operation instruction is received in the display area of the first screen, the terminal calls out a currently opened application program list of the first screen in the display area of the first screen;

Specifically, similar to the second operation instruction, the fourth operation instruction may also correspondingly include a total clear instruction and a selective clear instruction. As can be understood, when the fourth operation instruction corresponds to all the cleaning instructions, the terminal cleans all the application programs currently started on the first screen; when the fourth operation instruction corresponds to the selection cleaning instruction, the terminal cleans only the application programs which are opened in the first screen and are indicated by the fourth operation instruction.

Illustratively, the technical solution of this embodiment may also call up a list of currently-started application programs of the entire operating system of the terminal in the first screen, and the call may include:

when a preset fifth operation instruction is received in the display area of the first screen, the terminal calls out an application program list currently started by the whole operation system of the terminal in the display area of the first screen;

and the first screen receives a sixth operation instruction aiming at the application program list currently started by the whole terminal operating system, and the application programs currently started by the whole terminal operating system are cleaned according to the sixth operation instruction.

Specifically, similar to the second operation instruction, the sixth operation instruction may also correspondingly include a total cleaning instruction and a selective cleaning instruction. As can be understood, when the sixth operation instruction corresponds to all the cleaning instructions, the terminal cleans up the application program currently started by the whole operation system; when the sixth operation instruction corresponds to the selection cleaning instruction, the terminal only cleans the application program currently started by the whole operation system and indicated by the sixth operation instruction.

The embodiment provides a method for cleaning a background application program, wherein in the using process of a first screen, if a running pause phenomenon occurs in a terminal, an application program started in a second screen can be cleaned in the first screen, so that the background application program is cleaned by taking the screen as a unit, and the running of the application program in the first screen cannot be influenced after the background application program is cleaned.

Example two

Based on the same technical concept as the foregoing embodiment, referring to fig. 3, a detailed flow of a method for cleaning a background application according to an embodiment of the present invention is shown, where the flow may be applied to a terminal having at least a dual-screen display, and the flow may include:

s301: the terminal respectively records the current opened application program lists of a screen A and a screen B by taking the screen as a unit;

it should be noted that, both screens of the terminal are opened with applications, as shown in table 1, the list La of the currently opened applications in the screen a includes: application a1, application a2 and application A3; the application list Lb currently opened on the screen B includes: application B1 and application B2.

TABLE 1

La	Application A1	Application A1	Application A1
				Lb	Application B1	Application B2

S302: the terminal receives long pressing operation of a user on a menu key in a screen A, and calls a background program list of a screen B in the screen A;

specifically, the folder-type terminal having a dual-screen structure as shown in fig. 4 may include a screen a and a screen B, where two solid screens are respectively disposed on two sides of the folder and can be folded around a junction of the two solid screens as an axis, as shown by arrows in fig. 4. After the menu key of the terminal screen a receives the long-press operation of the user, the application list Lb currently opened on the screen B is displayed on the screen a, and a specific display diagram is shown in fig. 5.

It should be noted that, when the list Lb is displayed on the screen a, a key for clearing all the applications on the list Lb is also displayed on the screen a, such as "clear all" shown in fig. 5.

S303: when the terminal receives all cleaning instructions, the terminal cleans all application programs currently started on the screen B;

s304: when the terminal receives the selection cleaning instruction, the terminal only cleans the application programs started in the screen B, and selects the application programs indicated by the cleaning instruction.

With respect to steps S303 and S304, it should be noted that, referring to fig. 6, when the terminal receives an operation of the "clear all" key for the screen a, all the opened applications in the screen B are cleared, that is, the application B1 and the application B2 are cleared;

referring to fig. 7, when the terminal receives a selection clearing instruction for the application B2, for example, when the application B2 item in the hold list Lb is slid upwards, the application B2 opened in the screen B is cleared.

It can be understood that after the application program opened on the screen B is cleaned in the screen a, the screen a can still continue to run the opened application program, and the application program opened in the background is cleaned, so that the running karton phenomenon is eliminated.

It should be noted that the technical solution for the terminal to call out the self-started application program list in the screen a, clear the application program started by the screen a, call out the currently-started application program list of the entire operating system of the terminal in the screen a, and clear the currently-started application program of the entire operating system of the terminal is similar to the technical solution shown in fig. 3, and details are not repeated here in this embodiment.

EXAMPLE III

Based on the same technical concept as the previous embodiment, referring to fig. 8, a terminal 80 having at least a dual-screen display according to an embodiment of the present invention is shown, where the terminal 80 may include: an obtaining module 801, a first receiving module 802, a calling module 803, a second receiving module 804 and a cleaning module 805; wherein the content of the first and second substances,

the obtaining module 801 is configured to obtain currently-started application programs of a first screen and a second screen respectively;

the first receiving module 802 is configured to receive a preset first operation instruction in a display area of the first screen, and trigger the calling-out module 803;

the calling-out module 803 is configured to call out the currently opened application list of the second screen in the display area of the first screen;

the second receiving module 804 is configured to receive a second operation instruction for the currently opened application program list of the second screen;

the cleaning module 805 is configured to clean the currently opened application program of the second screen according to the second operation instruction.

Illustratively, the cleaning module 805 is configured to:

It should be noted that, for cleaning of the background application program, two manners of all cleaning and selective cleaning may be included, and correspondingly, the second operation instruction may also correspondingly include all cleaning instructions and selective cleaning instructions. As can be understood, when the second operation instruction corresponds to a full cleaning instruction, the cleaning module 805 cleans all the application programs currently opened on the second screen; when the second operation instruction corresponds to the selection cleaning instruction, the cleaning module 805 cleans only the application program which is opened in the second screen and is indicated by the second operation instruction.

For example, in the technical solution of this embodiment, a self-started application program list may also be called in the first screen, and therefore, the first receiving module 802 is further configured to receive a preset third operation instruction in a display area of the first screen;

the calling-out module 803 is further configured to call out a list of currently opened applications of the first screen in the display area of the first screen;

the second receiving module 804 is further configured to receive a fourth operation instruction for the application program list currently opened by the first screen;

the cleaning module 805 is further configured to clean the currently opened application program of the first screen according to the fourth operation instruction.

Specifically, similar to the second operation instruction, the fourth operation instruction may also correspondingly include a total clear instruction and a selective clear instruction. As can be appreciated, when the fourth operation instruction corresponds to a full cleaning instruction, the cleaning module 805 cleans all the applications currently opened on the first screen; when the fourth operation instruction corresponds to the selection cleaning instruction, the cleaning module 805 cleans only the application programs that are opened in the first screen and indicated by the fourth operation instruction.

For example, in the technical solution of this embodiment, the application program list currently started by the entire operating system of the terminal may also be called in the first screen, and therefore, the first receiving module 802 is further configured to receive a preset fifth operation instruction in the display area of the first screen;

the calling-out module 803 is further configured to call out an application program list currently started by the whole operating system of the terminal in the display area of the first screen;

the second receiving module 804 is further configured to receive a sixth operation instruction for an application program list currently started by the whole operating system of the terminal;

the cleaning module 805 is further configured to clean, according to the sixth operation instruction, an application currently started by the whole operating system of the terminal.

Specifically, similar to the second operation instruction, the sixth operation instruction may also correspondingly include a total cleaning instruction and a selective cleaning instruction. As can be understood, when the sixth operation instruction corresponds to the all-clean instruction, the cleaning module 805 cleans up the application program currently started by the entire operating system; when the sixth operation instruction corresponds to the selection cleaning instruction, the cleaning module 805 cleans only the application program currently opened by the entire operating system and indicated by the sixth operation instruction.

Illustratively, the first operation instruction comprises a single operation or a combination of multiple operations, and the operation corresponding to the first operation instruction does not conflict with existing operations of the operating system.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
