图2为一个实施例中计算机设备的部分架构图。如图2所示，计算机设备的架构系统中包括Java空间层210、本地框架层220以及内核(Kernel)空间层230。Java空间层中包括冻结和解冻模块212，上述冻结和解冻模块212用于实现对各个应用程序的冻结策略，例如对后台耗电的应用程序进行冻结等。Figure 2 is a partial architectural diagram of a computer device in one embodiment. As shown in FIG. 2 , the architecture system of the computer device includes a Java space layer 210 , a native framework layer 220 and a kernel space layer 230 . The Java space layer includes a freezing and thawing module 212, and the above freezing and thawing module 212 is used to implement a freezing strategy for each application, such as freezing an application that consumes power in the background.
本地框架层220中包括资源优先级和限制管理模块222、平台冻结管理模块224。上述资源优先级和限制管理模块222可对不同的应用程序进行不同的资源限制，使不同的应用程序处于不同的资源优先级中。资源优先级和限制管理模块222还可根据上层的需求调整应用程序的资源优先级，使得计算机设备可合理应用程序可使用资源。平台冻结管理模块224可根据应用程序进入后台的时长来确定对进程应用程序进行资源限制的等级，平台冻结管理模块224可预设不同的资源限制的等级，应用程序进入后台的时间越长，平台冻结管理模块224对应用程序进行资源限制的等级越高，即对应用程序的资源限制程度越高。可选地，上述资源限制等级可包括：CPU限制睡眠模式、CPU冻结睡眠模式和进程深度冻结模式。上述CPU限制睡眠模式是指对应用程序的进程可使用的中央处理器(CentralProcessing Unit，CPU)资源进行限制，使应用程序的进程可使用较少的CPU资源；在CPU限制睡眠模式下还可进一步限制应用程序的进程可使用的网络资源和输入/输出接口(input/output，I/O)资源。CPU冻结睡眠模式是指禁止应用程序的进程使用CPU资源、网络资源和I/O资源，但对应用程序的进程占用的内存资源不进行回收，上述CPU冻结睡眠模式是对应用程序可使用资源的深度限制模式。进程深度冻结模式是指禁止应用程序的进程使用CPU资源、网络资源和I/O资源，同时回收应用程序的进程占用的内存资源。其中，本地框架层220的接口模块包含开发给上层的binder接口，上层的框架或应用程序通过上述binder接口可发送资源限制指令给资源限制管理模块222、发送冻结指令给平台冻结管理模块224。The local framework layer 220 includes a resource priority and restriction management module 222 and a platform freeze management module 224. The above-mentioned resource priority and restriction management module 222 can perform different resource restrictions on different applications, so that different applications are in different resource priorities. The resource priority and limit management module 222 can also adjust the resource priority of the application program according to the requirements of the upper layer, so that the computer device can reasonably use the resources of the application program. The platform freeze management module 224 can determine the level of resource restriction for the process application according to the duration of the application entering the background. The platform freeze management module 224 can preset different resource restriction levels. The longer the application enters the background, the platform freezes. The higher the level of resource restriction performed by the freezing management module 224 on the application, the higher the degree of resource restriction on the application. Optionally, the above-mentioned resource restriction level may include: a CPU-limited sleep mode, a CPU-freeze sleep mode, and a process deep freeze mode. The above CPU-limited sleep mode refers to limiting the central processing unit (Central Processing Unit, CPU) resources that can be used by the process of the application program, so that the process of the application program can use less CPU resources; in the CPU-limited sleep mode, further Limit the network resources and input/output interface (input/output, I/O) resources that can be used by the process of the application. The CPU freeze sleep mode means that the process of the application program is prohibited from using CPU resources, network resources and I/O resources, but the memory resources occupied by the process of the application program are not recycled. The above CPU freeze sleep mode is for the resources available to the application program. Depth-limited mode. The process deep freeze mode means that the process of the application program is prohibited from using CPU resources, network resources and I/O resources, and at the same time, the memory resources occupied by the process of the application program are reclaimed. Wherein, the interface module of the local framework layer 220 includes a binder interface developed to the upper layer, and the upper layer framework or application program can send resource restriction instructions to the resource restriction management module 222 and freeze instructions to the platform freeze management module 224 through the above-mentioned binder interface.
内核空间层230中包括UID管理模块231、Cgroup模块232、binder管控模块233、进程内存回收模块234和超时冻结退出模块235。当前对应用程序的进程管理是基于进程识别号(Process Identification，PID)来实现的，进程与应用程序没有对应，不利于统一管理一个应用程序的所有进程对应的资源。上述UID管理模块231可通过应用程序的用户身份标识(User Identifier，UID)来管理应用程序的资源，也可通过应用程序的UID对应用程序进行冻结。Cgroup模块232可提供基于CPU、CPUSET、内存(memory)、I/O资源和Net相关的资源限制机制。binder管控模块233可用于限制后台进程间binder通信的优先级。进程内存回收模块234用于实现进程深度冻结模式，在进程进入进程深度冻结模式时，释放掉进程的文件区，从而实现节省内存，加快进程对应的应用程序下次启动时的速度。超时冻结退出模块235用于解决进程在冻结超时发生异常的问题。The kernel space layer 230 includes a UID management module 231 , a Cgroup module 232 , a binder management and control module 233 , a process memory recovery module 234 and a timeout freeze exit module 235 . The current process management of an application is implemented based on a process identification number (Process Identification, PID), and a process does not correspond to an application, which is not conducive to unified management of resources corresponding to all processes of an application. The above-mentioned UID management module 231 can manage the resources of the application through the user identifier (User Identifier, UID) of the application, and can also freeze the application through the UID of the application. The Cgroup module 232 can provide resource limitation mechanisms based on CPU, CPUSET, memory, I/O resources and Net-related resources. The binder control module 233 can be used to limit the priority of binder communication between background processes. The process memory recovery module 234 is used to realize the process deep freeze mode. When the process enters the process deep freeze mode, the file area of the process is released, so as to save memory and speed up the next startup of the application corresponding to the process. The timeout freezing and exiting module 235 is used to solve the problem that the process is abnormal during the freezing timeout.
通过上述的架构，可实现本申请各个实施例中的内存回收方法。Through the above-mentioned architecture, the memory recycling methods in the various embodiments of the present application can be implemented.

在一个实施例中，上述方法还包括：In one embodiment, the above method further includes:
步骤306，对后台应用程序设置资源优先级。Step 306 , set the resource priority for the background application.
步骤308，若检测到后台应用程序与前台应用程序具有通信机制和同步机制中至少一种，提升后台应用程序的资源优先级。Step 308, if it is detected that the background application and the foreground application have at least one of a communication mechanism and a synchronization mechanism, increase the resource priority of the background application.
计算机设备可对应用程序设置资源优先级。其中，计算机设备可根据应用程序的类型、应用程序的使用频次等对应用程序设定资源优先级。上述资源优先级是指对应用程序可使用资源的限制等级，应用程序对应的资源优先级不同，则应用程序可使用的资源的限制等级不同。应用程序对应的资源优先级越高，对应用程序可使用的资源的限制越少。上述可使用资源包括：CPU资源、内存资源、I/O资源和网络资源。例如，计算机设备可对应用程序设置5级优先级包括：第1级、第2级、第3级、第4级和第5级。其中，第1级优先级最高，第5级优先级最低。当应用程序处于第1级优先级时，各项资源可使用的比例为80％，即可使用CPU资源为总CPU资源的80％，可使用的内存资源为总内存资源的80％，可使用的I/O资源为总I/O资源的80％，可使用网络资源为总网络资源的80％。当应用程序处于第2级优先级时，各项资源可使用的比例为60％；当应用程序处于第3级优先级时，各项资源可使用的比例为40％；当应用程序处于第4级优先级时，各项资源可使用的比例为20％；当应用程序处于第5级优先级时，各项资源可使用的比例为10％。The computing device may set resource priorities for applications. The computer device may set resource priorities for the applications according to the type of the application, the frequency of use of the application, and the like. The above-mentioned resource priority refers to the restriction level of the resources that the application can use. If the resource priority corresponding to the application is different, the restriction level of the resource that the application can use is different. The higher the resource priority corresponding to the application, the less restrictive the resources that the application can use. The above usable resources include: CPU resources, memory resources, I/O resources, and network resources. For example, a computer device may set five levels of priority for applications including: level 1, level 2, level 3, level 4, and level 5. Among them, level 1 has the highest priority and level 5 has the lowest priority. When the application is at the first priority level, the available ratio of each resource is 80%, that is, the available CPU resources are 80% of the total CPU resources, and the available memory resources are 80% of the total memory resources. The available I/O resources are 80% of the total I/O resources, and the available network resources are 80% of the total network resources. When the application is at the second priority level, the available ratio of each resource is 60%; when the application is at the third priority level, the available ratio of each resource is 40%; when the application is at the fourth priority When the application is at the 5th priority level, the available ratio of each resource is 20%; when the application is at the 5th priority level, the available ratio of each resource is 10%.
应用程序的进程间通信机制包括socket、binder、共享内存等。网络上的两个程序通过一个双向的通信连接实现数据的交换，这个连接的一端称为一个socket。binder是一种进程间通信机制，提供远程过程调用功能。共享内存就是允许两个不相关的进程访问同一个逻辑内存，共享内存是在两个正在运行的进程之间共享和传递数据的一种非常有效的方式，不同进程之间共享的内存通常安排为同一段物理内存。应用程序的进程间同步机制是指并发程序设计中，各进程对公共变量的访问必须加以制约，这种制约称为同步。在操作系统中，用户态(user mode)的同步机制可通过调用futex系统调用实现。同步机制包括信号量、互斥锁等。当通过futex系统调用检测到与前台应用程序的进程存在任意一种同步机制的后台应用程序的进程时，可将检测到的后台应用程序作为被依赖应用程序。当后台应用程序与前台应用程序具有通信机制和同步机制中一种或多种时，可认为后台应用程序是前台应用程序的被依赖应用程序，即前台应用程序需要调用后台应用程序的数据才能顺利执行。The inter-process communication mechanism of the application includes socket, binder, shared memory, etc. Two programs on the network exchange data through a two-way communication connection, and one end of this connection is called a socket. Binder is an inter-process communication mechanism that provides remote procedure call functionality. Shared memory is all about allowing two unrelated processes to access the same logical memory. Shared memory is a very efficient way of sharing and passing data between two running processes. Memory shared between different processes is usually arranged as the same physical memory. The inter-process synchronization mechanism of an application program means that in the concurrent program design, the access of each process to the common variables must be restricted, and this restriction is called synchronization. In the operating system, the synchronization mechanism of user mode can be implemented by calling the futex system call. Synchronization mechanisms include semaphores, mutex locks, etc. When a process of a background application that has any synchronization mechanism with the process of the foreground application is detected through the futex system call, the detected background application can be used as a dependent application. When the background application and the foreground application have one or more of the communication mechanism and the synchronization mechanism, the background application can be considered as a dependent application of the foreground application, that is, the foreground application needs to call the data of the background application to be smooth. implement.
通常情况下，计算机设备对前台应用程序设定的资源优先级较高，对后台应用程序设定的资源优先级较低。当计算机设备检测到后台应用程序是前台应用程序所依赖的应用程序时，可检测后台应用程序的资源优先级与前台应用程序的资源优先级是否相同，若后台应用程序的资源优先级低于前台应用程序的资源优先级，则计算机设备可将后台应用程序的资源优先级提升到前台应用程序的资源优先级。In general, the computer device sets a higher resource priority for foreground applications, and lowers resource priorities for background applications. When the computer device detects that the background application is an application that the foreground application depends on, it can detect whether the resource priority of the background application is the same as that of the foreground application. If the resource priority of the background application is lower than that of the foreground application the resource priority of the application, the computer device may raise the resource priority of the background application to the resource priority of the foreground application.
本申请实施例中方法，当检测到后台应用程序是前台应用程序所依赖的应用程序时，可提高后台应用程序的资源优先级，后台应用程序可使用的资源增加，加快了后台应用程序响应前台应用程序的速度。In the method in the embodiment of the present application, when it is detected that the background application program is an application program that the foreground application program depends on, the resource priority of the background application program can be increased, the resources available for the background application program are increased, and the response of the background application program to the foreground program is accelerated. application speed.
在一个实施例中，还包括：当检测到前台应用程序结束对后台应用程序的依赖，降低上述后台应用程序的资源优先级。当后台应用程序不再是前台应用程序所依赖的应用程序时，将后台应用程序的资源优先级恢复到调整前较低的资源优先级。In one embodiment, the method further includes: when it is detected that the foreground application ends its dependence on the background application, reducing the resource priority of the background application. When the background application is no longer a dependent application of the foreground application, restore the resource priority of the background application to the lower resource priority before adjustment.
在一个实施例中，对后台应用程序进行资源限制包括：对后台应用程序进行冻结，禁止后台应用程序使用系统资源。In one embodiment, the resource limitation on the background application includes: freezing the background application, and prohibiting the background application from using system resources.
上述方法还包括：The above method also includes:
步骤310，若接收到对处于冻结状态的后台应用程序的唤醒消息，获取后台应用程序对应的唤醒时长。Step 310, if a wake-up message for the background application in the frozen state is received, obtain the wake-up duration corresponding to the background application.
步骤312，在当前时刻与后台应用程序上一次被唤醒的时刻之间的时间差不小于唤醒时长时，将处于冻结状态的后台应用程序唤醒。Step 312 , when the time difference between the current moment and the moment when the background application program was woken up last time is not less than the wake-up duration, wake up the background application program in the frozen state.
计算机设备还可对应用程序进行资源限制，其中，可根据应用程序进入后台的时长来确定对应用程序进行资源限制的等级。应用程序进入后台的时长越长，对应用程序进行资源限制的等级越高。计算机设备在对应用程序进行资源限制时，若将应用程序切换到进程深度冻结模式，则应用程序处于冻结状态。当应用程序处于冻结状态时，应用程序无法使用系统资源，因此无法响应其他应用程序的通信消息。上述冻结唤醒时长即为计算机设备预设的两次将应用程序由冻结状态唤醒的时间差。The computer device may also perform resource limitation on the application program, wherein the level of resource limitation on the application program may be determined according to the duration of the application program entering the background. The longer the application is in the background, the higher the level of resource throttling for the application. When the computer device restricts the resources of the application, if the application is switched to the process deep freeze mode, the application is in a frozen state. When an application is frozen, the application cannot use system resources and therefore cannot respond to communication messages from other applications. The above freezing and waking up duration is the time difference between two times preset by the computer device for waking up the application program from the frozen state.
当计算机设备接收到对处于冻结状态的应用程序的通信消息或系统消息时，可将计算机设备由冻结状态切换到可使用系统资源的状态，使得应用程序可响应上述通信消息或系统消息。其中，将应用程序由冻结状态切换到可使用系统资源的状态可为将应用程序由进程冻结状态切换到CPU限制睡眠状态，使得应用程序可使用系统资源。计算机设备也可对应用程序进行解冻，不限制应用程序使用系统资源。When the computer device receives a communication message or system message for the application program in the frozen state, the computer device can be switched from the frozen state to a state in which system resources can be used, so that the application program can respond to the above communication message or system message. The switching of the application program from a frozen state to a state in which system resources can be used may be switching the application program from a process frozen state to a CPU-limited sleep state, so that the application program can use system resources. The computer device can also unfreeze the application without restricting the application to use system resources.
在接收到对处于冻结状态的后台应用程序的唤醒消息后，计算机设备不会在每次接收到唤醒消息时就将后台应用程序唤醒。计算机设备可将当前时刻与后台应用程序上一次被唤醒时刻之间的时间差与上述唤醒时长进行对比。若上述时间差大于或等于唤醒时长，则计算机设备根据上述唤醒消息立刻将后台应用程序唤醒。若上述时间差小于唤醒时长，则计算机设备在当前时刻与上述后台应用程序上一次被唤醒的时刻之间的时间差等于上述唤醒时长时，将上述后台应用程序唤醒。即计算机设备在检测到当前时刻与上一次应用程序被唤醒时刻之间的时间差小于上述唤醒时长时，将在唤醒时长内接收到的唤醒消息积累，在当前时刻与上述后台应用程序上一次被唤醒的时刻之间的时间差等于上述唤醒时长时，根据积累的唤醒消息唤醒后台应用程序。若在上一次应用程序被唤醒后，在唤醒时长内未接收到唤醒消息，则在超过唤醒时长后接收到唤醒消息时，计算机设备可立即将上述后台应用程序唤醒。After receiving a wake-up message for a frozen background application, the computer device does not wake the background application each time it receives a wake-up message. The computer device may compare the time difference between the current moment and the moment when the background application was woken up last time with the above-mentioned wake-up duration. If the above-mentioned time difference is greater than or equal to the wake-up duration, the computer device immediately wakes up the background application program according to the above-mentioned wake-up message. If the time difference is less than the wake-up duration, the computer device wakes up the background application when the time difference between the current moment and the last time the background application was woken up is equal to the wake-up duration. That is, when the computer device detects that the time difference between the current moment and the last time when the application is woken up is less than the above-mentioned wake-up duration, it will accumulate the wake-up messages received during the wake-up duration, and the current moment and the last time the background application was woken up. When the time difference between the moments is equal to the above wake-up duration, wake up the background application according to the accumulated wake-up messages. If no wake-up message is received within the wake-up time period after the application program is woken up last time, the computer device can immediately wake up the above-mentioned background application program when the wake-up message is received after the wake-up time period expires.
通常情况下，为了节省计算机设备功耗和提高前台应用程序的可用资源，会对后台应用程序可用的资源进行限制，例如，对后台应用程序进行冻结。计算机设备在接收到对上述后台应用程序的唤醒消息时，需要将上述后台应用程序唤醒，否则上述后台应用程序会发生无响应的错误，但是频繁的将后台应用程序唤醒会导致计算机设备对后台应用程序的资源限制率降低，无法提高前台应用程序可用的资源。Generally, in order to save power consumption of computer equipment and increase the available resources of foreground applications, the resources available to background applications are restricted, for example, background applications are frozen. When the computer device receives the wake-up message for the above-mentioned background application, it needs to wake up the above-mentioned background application, otherwise the above-mentioned background application will have an unresponsive error, but frequently awakening the background application will cause the computer device to wake up the background application The resource limit rate of the program is reduced, and the resources available to the foreground application cannot be increased.
本申请实施例中方法，计算机设备可对对于冻结状态的应用程序设置唤醒时长，使得应用程序不会频繁被唤醒而浪费计算机设备功耗，又避免了应用程序长期处于冻结状态无响应的问题。In the method in the embodiment of the present application, the computer device can set the wake-up duration for the application program in the frozen state, so that the application program is not frequently woken up and wastes the power consumption of the computer device, and the problem that the application program is in the frozen state for a long time and does not respond is avoided.
在一个实施例中，上述方法还包括：In one embodiment, the above method further includes:
步骤314，若接收到对处于冻结状态的后台应用程序的终止命令，将后台应用程序解冻并将后台应用程序设定为不可冻结状态。Step 314, if a termination command for the background application program in the frozen state is received, unfreeze the background application program and set the background application program to a non-freeze state.
步骤316，根据终止命令关闭后台应用程序。Step 316, close the background application according to the termination command.
若计算机设备资源紧缺，计算机设备会对处于冻结状态的应用程序发送终止命令，关闭上述处于冻结状态的应用程序，释放上述应用程序占用的系统资源。但当应用程序处于冻结状态时，应用程序无法接收到任何消息，即使处于冻结状态的应用程序被唤醒，唤醒后应用程序也会快速恢复到冻结状态，因此计算机设备无法关闭处于冻结状态的应用程序。通常情况下，计算机设备会使用两套代码来终止应用程序，其中一套代码用于终止冻结状态应用程序，另一套代码用于终止其他应用程序。If the resources of the computer equipment are in short supply, the computer equipment will send a termination command to the application program in the frozen state, close the application program in the frozen state, and release the system resources occupied by the application program. But when the application is in the frozen state, the application cannot receive any messages, even if the application in the frozen state is woken up, the application will quickly recover to the frozen state after waking up, so the computer device cannot close the application in the frozen state . Typically, computer devices use two sets of codes to terminate applications, one set of codes for terminating frozen state applications and another set of codes for terminating other applications.
当计算机设备接收到对处于冻结状态的应用程序的终止命令时，若检测到上述应用程序处于冻结状态的处于冻结状态，对上述处于冻结状态的应用程序进行解冻，并将解冻后应用程序设置为不可冻结状态，则解冻后的应用程序可对上述终止命令正确响应，即上述解冻后的应用程序可被关闭。其中，对应用程序进行解冻可为不再限制应用程序使用的系统资源，也可为将应用程序由不可使用系统资源的状态切换到可使用系统资源的状态，如将应用程序切换到CPU限制睡眠模式。When the computer device receives the termination command for the application program in the frozen state, if it detects that the application program in the frozen state is in the frozen state, it unfreezes the application program in the frozen state, and sets the thawed application program to In the non-freeze state, the thawed application program can correctly respond to the above termination command, that is, the above thawed application program can be closed. Among them, unfreezing the application can no longer limit the system resources used by the application, or can switch the application from a state in which system resources cannot be used to a state in which system resources can be used, such as switching the application to CPU-limited sleep model.
本申请实施例中方法，可安全终止处于冻结状态的应用程序，避免出现应用程序无法终止的情况，计算机设备可根据统一的终止指令来终止处于冻结状态的应用程序和其他应用程序，实现了终止处于冻结状态的应用程序和其他应用程序的兼容性，减少了软件开发的困难，方便对移动操作系统进行维护。The method in the embodiment of the present application can safely terminate the application program in the frozen state, avoiding the situation that the application program cannot be terminated, and the computer device can terminate the application program in the frozen state and other application programs according to a unified termination instruction, realizing the termination The compatibility of the frozen application and other applications reduces the difficulty of software development and facilitates the maintenance of the mobile operating system.
