With the great popularization of the intelligent terminal, a user not only pays attention to the appearance and the visual effect of the intelligent terminal, but also pays more and more attention to the performance problem and the power consumption problem of the intelligent terminal, such as the power consumption speed of the terminal, smoothness of running, the memory use condition, the application program starting speed and other performance indexes. The available calculation and storage resources inside the intelligent terminal are usually limited, and when the intelligent terminal interacts with a user, if the terminal opens too many applications, the problems of power consumption, performance and the like of the terminal are influenced.
Moreover, many three-party applications have self-starting and wake-up situations by associated applications. For example, the user does not open the hundred-degree library, but only opens the hundred-degree video, the hundred-degree search, and the like, the user wakes up the hundred-degree library, and even after the user closes the applications, the applications can be woken up by other applications, or actions such as turning on a screen and turning on a screen of a mobile phone. Some applications may default to a timed wake-up service or, when one application exits, send a message to start another application or service. There are many services that do not provide an interface visible or operable to a user, but only run in the background, so that the background services without an interface, and the existing process monitoring technology may not monitor that they are started, and therefore cannot count the background services.
Therefore, in the process of interaction between the user and the intelligent terminal, if the application cannot be actively closed, a large number of processes may be running simultaneously, and some processes hang in the background and occupy system resources, thereby affecting the application interacting with the user and causing problems of high power consumption of the terminal and the like.
Therefore, a method for helping a user actively control the number of processes that a terminal can run simultaneously is needed to improve the user experience of the terminal.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention are described in detail below with reference to the accompanying drawings and examples, so that how to apply technical means to solve technical problems and achieve a technical effect can be fully understood and implemented.
Example one
The application scene of the monitoring control method for the terminal process is arranged on the mobile terminal. Fig. 1 is a flowchart of a monitoring control method for a terminal process according to the present invention, and each step is described in detail below with reference to fig. 1. As shown in fig. 1, the method mainly comprises the following steps:
s1: the newly created package name for the process is added to the collection, forming a collection containing the package names for the process.
In step S1, the set may be a running package name set with String as a data type for storing package names of management processes. Each packet name in the set has a respective number, e.g., the first packet name has a number of 0, the second packet name has a number of 1, and so on. Fig. 2 is a flowchart of adding a package name of a process to a set according to an embodiment of the present invention, and as shown in fig. 2, step S1 specifically includes:
s11: judging whether a package name of a newly created process exists in the set;
s12: and if the process name does not exist, adding the package name of the newly created process to a set to form a set containing the package name of the process.
If a new process is created, the object of the process listener acquires a message of the process creation, the message includes a package name of the process, and stores the package name into the set in step S1, after the application obtains a package name of the String type, it first determines whether the package name exists in the set, and if not, the package name of the String type is added to the set.
S2: and counting the number of the processes corresponding to the packet names in the set according to the packet names of the processes in the set.
S3: and when the number of the processes corresponding to the packet names in the set exceeds a preset value, acquiring all running processes, and determining n processes which are newly run in all running processes.
Specifically, the preset value and n can be determined according to the performances of other terminals such as a CPU, a memory and a terminal system of the terminal and according to actual conditions, so that when the terminal runs processes smaller than the preset value, the running condition is good, and the occurrence of the conditions that the user experience is affected by blocking and the like can be avoided. In the present embodiment, the preset value is 8, and n is 4. When the number of processes run by the terminal is greater than 8, in this embodiment, a getreporting application process method of the ActivityManager may be called to obtain all running processes, and then a getreporting task method of the ActivityManager may be called to determine the latest running 4 processes, that is, the latest running processes of the application or service. All the running processes are acquired here, and it is possible to avoid a situation where a process is created without being monitored during the monitoring process by the object of the listener in step S1.
S4: and destroying other running processes except the n newly running processes, and removing the packet names of the destroyed processes contained in the set from the set. And destroying the background running process in the terminal in batch. Fig. 3 is a flowchart of a destruction process according to an embodiment of the present invention, and as shown in fig. 3, S4 specifically includes:
s41: traversing all running processes, and acquiring the package name of each running process;
s42: destroying other running processes corresponding to the package names except the n processes running latest according to the acquired package names;
s43: removing from the collection the package names of the destroyed processes contained in the collection.
5. In this step, all running processes are traversed, and process information corresponding to the processes is extracted, where the process information includes the packet names of the processes, the numbers of the processes, and other description information. In this embodiment, except for 4 newly running processes, all the other processes execute the forceStopPackage method of ActivityManager according to the package names of the processes to destroy the running of the processes. After each execution of the forceStopPackage method of ActivityManager, the package name of the process contained in the set is removed by a set removal (remove) method, which indicates that the process is destroyed and is not within the statistics. It is worth noting that when the packet name is removed from the set, on the premise that whether the action of destroying the process is executed or not is avoided, under the condition that the feedback is destroyed by the process, part of the process is awakened after being destroyed and cannot be counted again by the set, and as a result, the packet name of the process is removed from the set, and the process corresponding to the removed packet name is still alive.
In the method, the set of packet names of the statistical process only plays a role in counting the number of the processes, and when the number triggering condition is met, the running process is obtained again, and the purpose of doing so is to eliminate the situation that some applications or services are started by themselves but are not counted into the set. By the method, the number of the processes running in the terminal can be strictly controlled within a set interval range, in the embodiment, the interval range is [ 4,8 ], which means that the maximum number of applications capable of running simultaneously is 8, and when the 9 th process is found, a killing condition is triggered, and some processes are closed. The preset value is set mainly according to the comprehensive setting of a terminal CPU, a memory and a mobile phone system, the faster the CPU processes, the strong performance of the terminal is shown, a plurality of applications can be considered simultaneously, the memory is mobile phone resources, each application needs the memory when running, and the larger the memory is, the more applications can be accommodated and run simultaneously; the smoother the terminal system, the faster the logic and speed of processing. The application preset values which can run simultaneously can be flexibly changed according to the actual situation of the terminal equipment and the test verification data, so that the power consumption, the memory and the CPU utilization rate of the terminal are optimized.
Before implementing the present invention, a series of basic constructions have been performed in a system of a mobile terminal, in this embodiment, the mobile terminal uses an Android (Android) system, and the specific construction process is as follows:
1) in a framework layer of an Android system, a process creation identifier can be added to an information file describing a running process, wherein the information file can be a processdocument. The process creation identification may indicate the current state of the process, e.g., true (true) may indicate that the process has been created and false (false) may indicate that the process has been destroyed. When the process is created for the first time, the process creation identifier is set to true, and when the process is destroyed, the process creation identifier is set to false.
2) A process monitor is set in a basic core code block of a frame layer of an Android system, and in this embodiment, the process monitor may be iappprocesslist. The system method interface is provided with a process creating (onNewAppProcessCreated) and destroying (onoldappprocessded). The process monitor can acquire the information created by the process through the system method interface created by the process, and can also acquire the information destroyed by the process through the system method interface destroyed by the process.
3) Communication data exchange rules of process monitor registration and unregistration are added in a client and server method file of management system Binder communication of a framework layer of an Android system, and in the embodiment, the method file can be ActivityManagerNative. The exchange rules may enable mutual communication between processes.
4) The registration and unregistration actions of the process monitor are numbered and registered in an Application Programming Interface (API) file of a frame layer of the Android system, and in this embodiment, the API file of the system may be iactivtymanager.
5) In this embodiment, the activity management service file may be activitymanager service. In which it can be determined whether a process has been created. If the process is created for the first time, calling a process creation notification method (onNewAppProcessCreated) in the process listener, providing application package name information corresponding to the created process, and setting a process creation identifier to true by calling the process creation notification method to indicate that the process is created; if the process is destroyed, a process destruction notification method (onOldAppProcessDied) of the process listener is called in the monitoring code destroyed by the process, an application package name corresponding to the process destruction is provided, and the process creation identifier is set to false by calling the process destruction notification method. When the process is created, if the process is created for the first time, the process mark creation identifier is set to true; if the process is destroyed, the process creation identification is set to false.
6) And creating an object of a process monitor at the application end according to the Binder communication rule, rewriting the two methods to enable the object of the process monitor to be available, and registering the object of the process monitor to be effective, so that the creation and the destruction of the process can be monitored by the object of the monitor at the application end. The object of the process listener can also be used to obtain the package name of the process. If the process is created for the first time, at this time, the process creation identifier is set to true, and the object process of the process listener is notified that the object process has been created; before the process is not destroyed, the process creation identifier is always kept true, the process is invalid after being created again, and at the moment, the object of the process monitor does not need to be notified again; if the process is destroyed, at this point the process creation flag is set to false and the process listener is notified that the object process is destroyed.
By setting the set of the process packet names and the trigger condition for closing the process, when the trigger condition is met, all running processes are traversed by the method, and some self-starting or associated awakening applications and services are ensured to be completely closed without being contained in the set.
Furthermore, the present invention also provides a computer-readable storage medium in which a system program for monitoring control of a terminal process is stored, which when executed by a processor implements the above-described monitoring control method for a terminal process of the present invention. In the specific application: the storage medium can be arranged at a server side or a client side, and can also monitor and control the application of the terminal through a network, so that excessive processes running at the terminal can be closed timely and effectively.
The terminal mentioned in the invention can be a mobile terminal, including a smart phone, a tablet computer, a palm computer and various common portable mobile intelligent terminals. In addition, the processes mentioned in the present invention may include application processes and other services of the terminal.
The above embodiments are only specific embodiments of the present invention. It is obvious that the invention is not limited to the above embodiments, but that many variations are possible. All modifications attainable by one versed in the art from the present disclosure within the scope and spirit of the present invention are to be considered as within the scope and spirit of the present invention.
