The terminal may further comprise a network interface connected via a system bus, which may be an ethernet card or a wireless network card, etc., for communicating with an external terminal, such as a server.
In one embodiment, as shown in fig. 2, a partial architecture diagram of a terminal is provided. The architecture system of the terminal includes a JAVA space layer 210, a local framework layer 220, and a Kernel (Kernel) space layer 230. The JAVA space layer 210 may include a freezing and thawing application 212, and the terminal may implement a freezing policy for each application through the freezing and thawing application 212, and perform a freezing operation for a related application consuming power in the background. The local framework layer 220 includes a resource priority and constraint management module 222 and a platform freeze management module 224. The terminal can maintain different applications in organizations of different priorities and different resources in real time through the resource priority and limit management module 222, and adjust the resource group of the application program according to the requirement of an upper layer, so as to achieve the effects of optimizing performance and saving power consumption. The terminal may distribute tasks that can be frozen in the background to corresponding preset frozen layers of different levels according to the length of the freezing time through the platform freezing management module 224, and optionally, the frozen layers may include three layers, which are respectively: the CPU limits the sleep mode, the CPU freezes the sleep mode, the process depth freezes the mode. The CPU sleep limiting mode is used for limiting CPU resources occupied by related processes, so that the related processes occupy less CPU resources, and the spare CPU resources are inclined to other unfrozen processes, so that the occupation of the CPU resources is limited, and the occupation of network resources and I/O interface resources by the processes is correspondingly limited; the CPU freezing sleep mode means that the related process is prohibited from using the CPU, while the memory is reserved, when the CPU resource is prohibited from being used, the corresponding network resource and I/O interface resource are also prohibited from being used; the process depth freezing mode refers to that besides the CPU resource is forbidden to be used, the memory resource occupied by the related process is further recovered, and the recovered memory can be used by other processes. The kernel space layer 230 includes a UID management module 231, a Cgroup module 232, a Binder management module 233, a process memory reclamation module 234, and a freeze timeout exit module 235. The UID management module 231 is configured to manage resources of the third party application or perform freezing based on a User Identifier (UID) of the application. By UID it is more convenient to uniformly manage resources of one user's application than to perform process management based on process identity (Process Identifier, PID). The Cgroup module 232 is used to provide a complete set of central processing units (Central Processing Unit, CPU), CPUSET, memory, input/output (I/O) and Net related resource limiting mechanisms. The Binder management module 233 is configured to implement control of priority of background Binder communications. The interface module of the local framework layer 220 includes a binder interface opened to an upper layer, and an upper layer framework or application sends a resource restriction or freezing instruction to the resource priority and restriction management module 222 and the platform freezing management module 224 through the provided binder interface. The process memory reclamation module 234 is configured to implement a process deep freeze mode, so that when a certain third party application is in a frozen state for a long time, a file area of the process is mainly released, thereby achieving a memory saving module, and also accelerating the speed of the application when the application is started next time. The freeze timeout exit module 235 is configured to solve an exception generated by the occurrence of the freeze timeout scenario. Through the architecture described above, the application freezing method in the various embodiments of the present application can be implemented.
In one embodiment, as shown in fig. 3, an application freezing method is provided for freezing an application running on a terminal. The present embodiment will be described by taking an example in which the method is applied to a terminal as shown in fig. 1. The application freezing method comprises the following steps:
step 302: and acquiring a first application program running on the terminal, and detecting whether a second application program under the same user identity with the first application program exists.
An Application (APP) is a computer program that operates in a user mode to interact with a user and has a visual user interface for performing a particular task or tasks. In this embodiment, an Android operating system (Android OS) is taken as an example, in the Android operating system, each application program has a user identity (User identification, uid), only two application programs with the same Uid can share data, for example, in order to share data of two different application programs, by setting shared Uid (sharing Uid), an application program a and an application program B can be set to the same Uid, and if the application programs a and B can call data mutually in the running process, otherwise, if the Uid of the application program a and the Uid of the application program B are different, the application program a and the application program B cannot call data at will. It will be appreciated that in other operating systems, such as IOS, symbian, etc., there are also the same or corresponding data call principles between different applications.
The first application program running on the terminal can be a foreground application program or a background application program, the UID of the first application program is obtained, whether a second application program which is the same as the UID of the first application program exists or not is detected, whether the first application program and other application programs have a mutual calling relationship or not can be judged, and whether the first application program is directly frozen or not can be judged to influence other application programs or not. It will be appreciated that there may be one or more second applications that are identical to the Uid of the first application, and as such, the second application may be a foreground application or a background application.
Step 304: and detecting whether the second application program is in a normal working state or not when the second application program exists.
If there is a second application program which is the same as the UId of the first application program, the first application program and other application programs are related to each other in calling, and if the first application program is to be frozen, the running state of the second application program sharing data with the first application program needs to be detected, and the first application program is frozen by combining the running state of the second application program.
In one embodiment, the terminal may detect the process of the second application according to a preset frequency or according to a detected user operation instruction, and obtain the current running state of the second application by detecting the process state of the second application. The operation of an application is typically embodied by the operation of a plurality of processes in association. The process related to the running of the foreground application program is the foreground process, and the process related to the running of the background application program is the background process. Alternatively, a process identifier of the second application program may be acquired, where the process identifier is used to uniquely identify a corresponding process, and may be formed by one or a combination of several digits, letters, or other characters with a preset number of digits. For example, the process identifier "0001" may be used to represent the process a, the process "1234" may be used to represent the process B, and the running states of the processes identified by the different processes may be detected, so that it may be known whether the second application operates in the background running state or the foreground running state.
Step 306: when the first application program needs to be frozen, if the second application program is in a normal working state, a corresponding preset freezing strategy is adopted to freeze the first application program according to the working state of the second application program.
The normal working state includes, but is not limited to, a foreground running state and a background holding state. Specifically, an application program corresponding to an operation page of an application program displayed on a current display interface of the terminal is a foreground application program currently operated by the terminal. In this embodiment, only the application corresponding to the input focus is the foreground application, or only the application corresponding to the window object located at the top of the window stack of the operating system is the foreground application currently corresponding to the terminal. Whether the target application program is a foreground application program is determined, a window object corresponding to the target application program is obtained, whether the window object is positioned at the stack top of a window stack of an operating system is judged, if yes, the target application program is the foreground application program, if not, the application program is operated in the background, and the application program is the background application program. The foreground application program works in a foreground running state, and the background application program works in a background running state; the background holding state refers to that an application program works in a background running state, but a user has a requirement on the application program, and needs that the application program keeps the background running state, for example, a music player, usually, after the user starts the music playing, the user enters other program operation interfaces, and at the moment, the music player works in the background holding state, and the concert continues playing.
The terminal can judge whether the first application program needs to be frozen or not according to the working state of the first application program, if the first application program works in a background working state and a user temporarily does not need to use the first application program, the first application program can be frozen, if the second application program is detected to be in a normal working state at the moment, the first application program is directly frozen to influence the operation of the second application program because the UId of the first application program is the same as that of the second application program, and the first application program is frozen according to a preset freezing strategy at the moment, so that the working of the first application program and the second application program is ensured not to be abnormal.
According to the application freezing method, whether the second application program which is in the same user identity with the first application program exists is detected by acquiring the first application program which runs on the terminal, when the second application program exists, whether the second application program is in a normal working state is detected, and when the first application program needs to be frozen, if the second application program is in the normal working state, the corresponding preset freezing strategy is adopted to freeze the first application program according to the working state of the second application program, intelligent freezing operation can be realized according to the working states of different applications under the same user identity, abnormal freezing is avoided, and user experience is improved.
In one embodiment, as shown in fig. 4, the detecting whether there is a second application program under the same user identity as the first application program includes the following steps:
step 402: and acquiring the user identity identifier allocated to the first application program by the operating system.
Under the default condition, the android operating system can allocate a Uid with different common levels to each application program, if different application programs need to be called mutually, only the Uids of different application programs can be called mutually, so that shared data among different application programs has certain security, data cannot be obtained randomly among each application program, and only one Uid corresponds to each application program. The terminal reads the UID of the first application program and judges whether a second application program which is the same as the UID of the first application program exists or not.
Step 404: and when the application programs which share data with the first application program and have the same user identity are present, the application program which can be mutually called with the first application program is taken as a second application program.
Further, the terminal detects whether an application program sharing data with the first application program exists, when detecting that other application programs share data with the first application program, the terminal obtains the UID of the application program, and if the UID of the application program is identical to the UID of the first application program, the application program is considered to be a second application program which can be mutually called with the first application program. Such a situation occurs in many different applications developed by the same company, for example, when one company makes two products, only if two products can be called each other, shared Uid can be used to set Uid of two software to be identical, in which case a signature document with the company signature must be used to share data. Alternatively, it may be a different application under Shared UId of the system with its own software.
According to the application freezing method, whether the second application program under the same user identity with the first application program exists or not is detected, when the second application program exists, the first application program can be frozen by combining the running state of the second application program, the phenomenon that the second application program cannot normally run due to direct freezing of the first application program is avoided, memory resources are saved, meanwhile, running of the application program is not affected, and user experience is improved.
In one embodiment, during the process of freezing the first application program, detecting whether the second application program is in a normal working state, if the second application program is in a foreground running state, freezing the first application program, and keeping the running state of the second application program unchanged. When the first application program needs to be frozen and the second application program which is identical to the UID of the first application program is detected to be in a foreground running state, if the first application program is directly frozen at the moment, the second application program B which is identical to the UID of the user logged in by the first application program is frozen based on the user group, so that the freezing strategy needs to be changed, and other applications which are identical to the UID of the user logged in by the background application are not frozen based on the user group.
Specifically, as shown in fig. 5, the freezing the first application program, and keeping the running state of the second application program unchanged, includes:
step 502: and acquiring all process identifiers under the user identity identifier.
The process identifier (Process identification; pid) represents a process ID, and the process (process) is a running activity of a program in a computer on a certain data set, is a basic unit for resource allocation and scheduling of a system, and is a basis of an operating system structure. The operation of an application is typically embodied by the operation of a plurality of processes in association. The process identification includes a process identification of the first application and a process identification of the second application.
In this embodiment, all process identifiers under the same Uid are read, and for example, two processes are generated when the application program "jindong" runs: the first process 12041 and the second process 12607, in which the file content of the first process is "com.jingdong.app.mall" is displayed in the path of the file library/proc/12041/cmdline, and the file content of the second process is "com.jingdong.app.mall:jdpush" is displayed in the path of the file library/proc/12607/cmdline, and both processes include the package name "com.jingdong.app.mall" of "jingdong", so that all processes of the application program "dong" in operation can be found by acquiring the related processes of the package name "com.jingdong.app.mall".
Step 504: and screening out the process identification of the first application program according to the file package name of the first application program.
The file package names of the application programs are recorded in the file library, and the file package names of different application programs can be inquired by reading the file package names in the file library. Files containing the form "package name: process" may be read, for example, by path kernel/proc/pid/cmdline. And screening the process identification only comprising the file package name of the first application program according to the file package name of the first application program, thereby obtaining the process identification of the first application program.
Step 506: and freezing a background process of the first application program according to the process identification of the first application program.
Specifically, after the process identifier of the first application program is obtained, a background process of the first application program can be frozen according to the process identifier of the first application program, for example, all/proc/pid/cmdline pids containing the package name of the first application program are frozen. The related process of the first application program is frozen by the freezing process mode, and the running state of the second application program which is the same as the UID of the first application program is not affected.
In one embodiment, during the process of freezing the first application program, whether the second application program is in a normal working state is detected, and if the second application program is in a foreground working state and the second application program depends on the first application program, the working states of the first application program and the second application program are kept unchanged.
Wherein the dependency represents a relationship that represents data that one application needs to utilize for another application or applications to successfully implement execution of the one application. The two application programs with the dependency relationship are a dependent application program and a dependent application program respectively, and the terminal takes the detected background application program which is to be depended on by the first application program as a second application program. When the first application is relied on by the second application under the same UId, the first application and the second application are not frozen.
For example, the application a depends on the application B, or the application B depends on the application a, that is, the application a needs to use the data of the application B to implement the execution of the application a, and at this time, the application a is the dependent second application, and the application B is the first application. It will be appreciated that the dependent application may also be a first application and the second application may be a background application. The terminal may detect from the set of background applications to query whether there are applications that are relied upon by the first application.
In one embodiment, during the process of freezing the first application program, detecting whether the second application program is in a normal working state, and if the second application program is in an abnormal working state, freezing the first application program and the second application program under the same user identity when the first application program needs to be frozen.
According to the application freezing method provided by the embodiment, when the second application program is in the foreground running state, the first application program is frozen, and the running state of the second application program is kept unchanged; if the second application program is in a foreground running state and the second application program depends on the first application program, keeping the running states of the first application program and the second application program unchanged; and if the second application program is in an abnormal working state, when the first application program needs to be frozen, the first application program and the second application program under the same user identity are frozen. The freezing mode of the application can be realized by intelligently combining the working states of different applications under the same user identity, the freezing range is increased, and the system resources are better optimized.
In one embodiment, as shown in fig. 6, before the freezing the first application program according to the preset freezing policy, the method further includes the following steps:
Step 602: detecting operation information acting on the first application program; the operation information includes an operation mode and an operation time point.
When the application program is started on the terminal, the application program can monitor the operation information input by the user. The operation information includes an operation mode and an operation time point input by a user. The operation modes at least comprise input operation modes such as keys, voice, touch, fingerprint, scanning and the like. Meanwhile, when operation information input by a user is received, the currently input operation time point is also acquired. For example, when an application program is started, it monitors all input information of the user, such as input of different operation modes of voice, touch, etc., when the user uses the application program, and at the same time, the input time point corresponding to the current input mode, such as voice input-20:00:00, is recorded; touch input-20:00:01, etc.
Step 604: and determining whether the first application program needs to be frozen at the current moment according to the operation information.
Each application corresponds to one or more freeze conditions, which may be determined based on the manner of operation in which the user input is received. In this case, it is possible to set one freezing condition for one operation mode, for example, the first freezing condition for the touch operation mode, the second freezing condition for the voice operation mode, the third freezing condition for the scan operation mode, and so on. That is, each mode of operation that each application can reach may correspond to a freeze condition.
Further, the freezing condition is a time condition, and a time freezing condition corresponding to each operation mode can be set, and the time freezing condition can be understood as that when certain operation information is not monitored within a preset duration, the time freezing condition is considered to be met.
The operation modes of each application are different, and freezing conditions corresponding to the same operation mode of different applications may be the same or different.
According to the preset mapping relation, whether the first application program needs to be frozen or not at the current moment can be judged according to the monitored operation information.
In one embodiment, as shown in fig. 7, the determining whether the first application program needs to be frozen at the current moment according to the operation information includes the following steps:
step 702: and acquiring the operation information closest to the current moment, and recording the time interval between the operation time point of the operation information and the current moment.
When an application program on the terminal runs, the terminal monitors operation information input by a user, wherein the operation modes at least comprise input operation modes such as keys, voice, touch, fingerprint, scanning and the like. Meanwhile, when operation information input by a user is received, the currently input operation time point is also acquired.
The latest operation information may be operation information corresponding to an operation time point with the shortest time interval at the current moment, among all operation information received from the user input, from the current start of the application program.
If the current time is 20:30:00 a night, the foreground of the terminal is running the first application program, the user can operate the display page of the application program in the process of using the first application program, and the terminal can monitor the operation information input by the user in real time. At the current time (20:30:00), the terminal acquires the operation information (operation mode and operation time point) which is monitored last time from the current time (20:30:00), if the operation mode is a touch operation mode in the latest operation information and the operation time point is 20:20:00, the terminal can acquire the time interval from the current time, and the time interval is 10 minutes.
Step 704: and when the time interval meets a preset freezing condition, the first application program needs to be frozen.
Specifically, the preset freezing condition may be a time condition, a historical operation duration of each application running in the foreground may be different, an operation manner of receiving the user input may be different, and the corresponding freezing condition may be set for each application. For example, when the first application program works in a foreground running state, the freezing condition of the first application program can be divided according to the received operation mode, and if the first application program does not monitor touch operation within a first preset duration, the first freezing condition is met; when the first preset time period is longer than a preset multiple of the use frequency (120 times/min) of the touch operation mode, it can be determined that the touch operation mode is not generated any more in the first preset time period, and it can be determined that the user does not use the first application program currently running and needs to freeze the first application program.
Optionally, when the first application program works in the foreground running state, if no voice operation is monitored within a second preset time period, the second freezing condition is satisfied. The second preset duration is related to the use frequency in the history operation record, and when the second preset duration is longer than a preset multiple of the use frequency (1 time/5 minutes) of the voice operation mode, the voice operation mode can be determined not to be regenerated in the second preset duration, which indicates that the user is determined not to use the first application program currently running and needs to freeze the first application program.
It should be noted that the first preset duration and the second preset duration may be set according to the needs of the user, which is not limited herein.
In one embodiment, the preset freezing condition may further include detecting whether a user exists, and when the time interval satisfies the preset freezing condition, it may be determined that the user does not operate the application program at this time, and whether the user exists in front of the current terminal may be determined by detecting whether the face image exists in the visual area of the current terminal through the terminal. The visual area may be understood as an area where the user can normally use the terminal, or may be understood as a distance between the user and the terminal, which is a comfortable distance for the user to use the terminal.
Specifically, whether a person exists in front of the terminal can be detected through a face recognition technology. Face recognition is a biological recognition technology for carrying out identity recognition based on facial feature information of people. An image or video stream containing a face image is acquired by a camera or a camera (front camera), and the face image is automatically detected and tracked in the image, so that a series of related technologies of face recognition, commonly called face recognition, and face recognition, are performed on the detected face image. Through terminal processing, if the face image is identified, the user is shown to watch the display area of the terminal, and the user does not operate the terminal; if the face image does not exist, the fact that the user is not using the terminal currently is indicated, and the first application program can be frozen. When no face image exists, the current user is far away from the terminal, and the first application program running currently can be frozen, so that power consumption is saved.
In one embodiment, the application freezing method further comprises: obtaining a defrosting instruction for defrosting the first application program; detecting whether the biological characteristic information in the thawing instruction is matched with a preset biological characteristic; and when the biological characteristic information in the thawing instruction is matched with the preset biological characteristic, thawing the first application program.
That is, when the first application program needs to be thawed after being frozen, a thawing instruction input by the user needs to be acquired. The defrosting instruction includes biometric information, wherein the biometric information may be fingerprint information, iris information, voiceprint information, face information, and the like.
It should be noted that different applications may set different biometric information, or may set the same biometric information, and may be set in a user-defined manner according to a user's requirement.
And when the biological characteristic information in the thawing instruction is matched with the preset biological characteristic information, thawing the background application program. During the defrosting operation, a corresponding defrosting strategy can be set according to the freezing strategy, so that the defrosting operation of the first application program can be realized.
