In one embodiment, as shown in FIG. 2, a partial architecture diagram of an electronic device is provided. The architecture system of the electronic device includes a JAVA space layer 210, a local framework layer 220, and a Kernel space layer 230. The JAVA space layer 210 may include a freezing management application 212, and the electronic device may implement a freezing policy for each application through the freezing management application 212, and perform a freezing operation on the related application consuming power in the background. A resource priority and restriction management module 222 and a platform freeze management module 224 are contained in the local framework layer 220. The electronic device can maintain different applications in organizations with different priorities and different resources in real time through the resource priority and restriction management module 222, and adjust the resource groups of the application programs according to the requirements of the upper layer, thereby achieving the effects of optimizing performance and saving power consumption. The electronic device may allocate, according to the length of the freezing time, the task that the background can be frozen to the freezing layers corresponding to the preset different levels through the platform freezing management module 224, and optionally, the freezing layers may include three, which are: CPU limited sleep mode, CPU frozen sleep mode, process deep frozen mode. The CPU sleep-restricted mode is to restrict CPU resources occupied by related processes, so that the related processes occupy less CPU resources, and the vacant CPU resources are inclined to other processes which are not frozen, so that the occupation of the CPU resources is restricted, and the occupation of network resources and I/O interface resources is correspondingly restricted; the CPU freezing sleep mode means that related processes are forbidden to use the CPU, the occupation of a memory is reserved, and when CPU resources are forbidden to use, corresponding network resources and I/O interface resources are also forbidden to use; the process deep freezing mode is to further recycle the memory resources occupied by the relevant processes except for forbidding the use of CPU resources, and the recycled memory can be used by other processes.

The timeout freeze exit module 235 is used to resolve the exception generated by the freeze timeout scenario. Through the above-mentioned architecture, the application processing method in each embodiment of the present application can be realized.
In one embodiment, an application processing method is provided and exemplified by being applied to the electronic device, as shown in fig. 3, including the following steps:
The external storage device is a device which exists outside the electronic device or is embedded in a slot of the electronic device and can be used for storing data, and the common external storage device can be a hard disk, an optical disk, a usb disk, a removable hard disk, a memory card, and the like. The external storage device can be connected with the electronic device and used for expanding the storage capacity of the electronic device. Frozen applications refer to applications that are in a frozen state.
The electronic device can monitor the connection state of the external storage device, and when the electronic device detects that the connection of the external storage device exists, the electronic device can acquire the application in the frozen state.
The read-write permission of the application can be the access permission of the application set by a user or a system default to a certain type of files, and the user can set the read-write permission of the application through application permission management in the electronic equipment. For example, when a user wants to set the read-write permission of the short message application, the read-write permission of the short message application can be set to be forbidden through application permission management in the electronic device, and the short message application loses the read-write permission.
The read-write permission of the application in the frozen state can also be set by the user through application permission management.

And when the read-write authority of the frozen application is in a forbidden state, the frozen application is represented to have no read-write authority, and on the contrary, when the read-write authority of the frozen application is in an allowed state, the frozen application is represented to have the read-write authority.
When the read-write right of the frozen application is in an allowed state, namely the frozen application has the read-write right, the electronic equipment can wake up the frozen application. In particular, the manner in which the electronic device wakes up the frozen application may be by sending a message to the frozen application.
And when the connection of the external storage device is detected, acquiring the frozen application, inquiring the read-write permission of the frozen application, and if the frozen application has the read-write permission, awakening the frozen application. The awakened freezing application scans the files in the external storage device, so that the loss of the files in the external storage device can be avoided, the electronic device does not need to be restarted to read the files in the external storage device, and the reading efficiency is improved.
In an embodiment, the provided application processing method may further include a process of querying the read-write permission of the frozen application, where the specific process includes: and acquiring a preset application read-write permission table, and inquiring the read-write permission of the frozen application from the application read-write permission table.
The application read-write permission table is preset, and the read-write permission table stores read-write permissions of all applications of the electronic equipment, including read-write permission of frozen applications and read-write permission of non-frozen applications.
The electronic equipment can acquire a preset application read-write permission table, and the electronic equipment can also inquire the acquired application read-write permission table to acquire the read-write permission of the frozen application.
And inquiring the read-write permission of the frozen application from the application read-write permission table by acquiring a preset application read-write permission table. Due to the fact that the preset application read-write permission table is obtained, the electronic device can find out the read-write permission of the frozen application more quickly and accurately, and therefore the efficiency of finding out the read-write permission of the frozen application by the electronic device is improved.
In another embodiment, as shown in fig. 4, an application processing method is provided, which includes the following specific steps:
All the applications in the frozen state are stored in the frozen application list, and the applications in the frozen state in the frozen application list can be arranged according to the length of the frozen time or the priority of the frozen applications. Traversal refers to sequentially making one and only one visit to all nodes in the list along a certain route.
The electronic device may obtain the frozen application list, and traverse the frozen applications according to the order arranged in the frozen application list, that is, sequentially access the frozen applications in the frozen application list.
In the process of traversing the frozen application, the electronic device can sequentially query the read-write permission of the frozen application. For example, the electronic device may perform READ-WRITE permission search operation of a corresponding application in a corresponding application Management module through WRITE _ EXTERNAL _ STORAGE and READ _ EXTERNAL _ STORAGE in the android System, and the application Management module may be a PMS (Plant Management System device Management System). The electronic device can also query the read-write permission of the frozen application from the application read-write permission table.
And 406, if the frozen application has the read-write permission, marking the frozen application.
When the inquired frozen application is in a read-write permission state, namely has the read-write permission, the electronic equipment can mark the frozen application with the read-write permission.
The freezing application with the mark belongs to the freezing application with the read-write permission, and the electronic equipment can wake up the freezing application with the read-write permission.
The frozen application list is obtained, the frozen applications in the frozen application list are traversed, the read-write permission of the frozen applications in the frozen application list is inquired, if the frozen applications have the read-write permission, the frozen applications are marked, and the frozen applications with the marks in the frozen application list are awakened. The awakened freezing application is marked freezing application with read-write permission, so that the accuracy of awakening the freezing application by the electronic equipment is improved.
As shown in fig. 5, in another embodiment, an application processing method is provided, which includes the following specific steps:
The monitoring unit is a unit for monitoring whether the external storage device and the electronic device have a connection relationship. The connection event refers to an event that the external storage device establishes a connection relationship with the electronic device. For example, the monitoring unit may monitor the moved and unounted information of the external storage device, i.e., the connection establishment information and the connection non-establishment information of the external storage device.
After the monitoring unit monitors whether a connection event exists between the external storage device and the electronic device, the monitored result can be sent to the electronic device, and the electronic device can obtain the monitoring result of monitoring the connection event of the external storage device through the monitoring unit of the inner core layer of the operating system.
When the monitoring unit monitors an event of connecting the external storage device, the monitoring unit may send a detection result of detecting the connection event to the electronic device, indicating that the external storage device is connected to the electronic device. When an external storage device is connected to the electronic device, the electronic device may send a message to the local framework layer through the kernel layer of the operating system to trigger the scan thread to start.
The frozen application list may be pre-set to store applications in a frozen state. The scan thread exists inside the electronic device for scanning various data and applications in the electronic device.
The electronic device can acquire the frozen application list through the scanning thread, and the electronic device can access the frozen applications in sequence according to the sequence in the frozen application list.
Monitoring a connection event of the external storage device through a monitoring unit of an inner core layer of the operating system, when the event of the external storage device is monitored, triggering and starting a scanning thread when the event of the external storage device is detected, acquiring a frozen application list through the scanning thread, and traversing the frozen applications in the frozen application list. By monitoring the connection state of the external storage equipment, the frozen applications in the frozen application list are traversed when the connection of the external storage equipment is monitored, and the accuracy of the electronic equipment in traversing the frozen applications is improved.
In an embodiment, the application processing method provided by the present invention may further include a process of waking up the frozen application, where the specific process includes: and switching the frozen application from a third-stage freezing state to a first-stage freezing state or a normal running state, wherein the third-stage freezing state is a memory limitation state, the first-stage freezing state is a state that the utilization rate of processor resources is less than a processor resource threshold value, and the normal running state is a state that the processor resources are not limited.
The memory limitation state refers to a state in which the resource memory occupied by the application is limited and the application cannot normally run, i.e., a deep freezing state. The state that the utilization rate of the processor resources is less than the threshold value of the processor resources indicates that the resources used by the application are less than the threshold value of the processor resources, the threshold value of the processor resources is preset, and the threshold value of the processor resources of each application can be different. When the application is in a state where the utilization rate of the processor resources is less than the threshold value of the processor resources, the running of the application is partially limited, which is equivalent to the application being in a light sleep state.
The electronic device may wake the frozen application by sending information to the frozen application. The state of the frozen application after waking up can be a state that the utilization rate of the processor resources is less than the threshold value of the processor resources, or a state that the processor resources are not limited.
In one embodiment, the application processing method provided may further include: and scanning the external storage device by the awakened freezing application to acquire a corresponding file in the external storage device. After the electronic device wakes up the frozen application, the woken-up frozen application can scan files in the external storage device, and then the scanned files related to the wakened-up frozen application authority are loaded into the woken-up frozen application. The permission-related file refers to a file that the wakening frozen application can read.
The scanned file is loaded into the awakened freezing application, so that the loss of the file in the external storage device can be avoided.
In an embodiment, the method for processing an application provided may further include a process of performing a hierarchical wakeup on the frozen application, where the specific process is as follows: and classifying the frozen applications according to the read-write permission of the frozen applications to obtain the grades of the frozen applications, and awakening the frozen applications in sequence according to the grades.
The electronic device may rank the frozen applications according to their read-write permissions. For example, applications with both read and write permissions are classified into a first tier, and applications with only read or only write permissions are classified into a second tier. The electronic device may also obtain a level of frozen applications, and applications with a high level of priority may perform a wake-up operation, for example, to wake-up the applications with the first level and then wake-up the applications with the second level.
The electronic equipment grades the frozen applications according to the read-write permission, so that the applications are sequentially awakened according to the application grade, and the problem of system resource waste caused by awakening too many applications at one time can be avoided.
In an embodiment, the method for processing an application provided may further include a process of performing a hierarchical wakeup on the frozen application, where the specific process is as follows: and grouping the frozen applications according to the association degree of the frozen applications with the read-write permission to obtain the quantity information of the frozen applications of different groups, and sequentially waking up the applications of the different groups from more than one to less or from less than one to more according to the quantity of the applications in the frozen application groups.
Wherein, the association degree of the frozen applications refers to the degree of association of different frozen applications. The electronic equipment can group the frozen applications according to the association degree of the frozen applications with the read-write permission, and the associated applications are grouped into one group. For example, the electronic device may divide the short message applications and the chat applications of the frozen received information with the read-write permission into a first group, where the number of the applications in the first group is 2, and may further divide the music playing applications of the frozen played music with the read-write permission into a second group, where the number of the applications in the second group is 1. The electronic device may wake up the applications in order of from many to few or from few to many of the number of applications in each group. For example, the number of applications in the first group is 2, the number of applications in the second group is 1, the electronic device may wake up the applications in the order from the largest number of applications, that is, wake up the applications in the first group first and then wake up the applications in the second group, and the electronic device may wake up the applications in the order from the smallest number of applications, that is, wake up the applications in the second group first and then wake up the applications in the first group.
In one embodiment, the application processing method provided may further include: and after the unfrozen application scans to obtain the file in the external storage device, the file is frozen again.
The unfrozen application can scan files in the external storage device and load the files into the corresponding unfrozen application. After the unfrozen application scans to obtain the file in the external storage device, the electronic device can perform the re-freezing operation on the unfrozen application.
And after the unfrozen application scans to obtain the file in the external storage device, the file is frozen again. By freezing the unfrozen application again, system resources can be saved.
In one embodiment, the application processing method provided may further include: and after the unfrozen application scans to obtain the file in the external storage device, freezing the unfrozen application according to a preset time interval.
The time interval may be preset, and different time intervals may be set for different applications. For example, the time interval of the music playing application may be set to 30 minutes. After the frozen application is unfrozen and scanned to obtain a file in the external storage device, when the unfrozen application is not used at a preset time interval, the electronic device can unfreeze the unfrozen application again. For example, after the music playing application is thawed and a music file in the external storage device is scanned, the electronic device may freeze the music playing application again within 30 minutes without the music playing application being run.
And after the unfrozen application scans to obtain the file in the external storage device, freezing the unfrozen application according to a preset time interval. By refreezing the unused applications at the preset time interval, waste of system resources can be avoided.
In one embodiment, an application processing method is provided, and the specific steps for implementing the method are as follows:
first, the electronic device may monitor a connection event of the external storage device through a monitoring unit of a kernel layer of the operating system. After the monitoring unit monitors whether a connection event exists between the external storage device and the electronic device, the monitored result can be sent to the electronic device, and the electronic device can obtain the monitoring result of monitoring the connection event of the external storage device through the monitoring unit of the inner core layer of the operating system. When an event of connecting the external storage device is monitored, the fact that the external storage device is connected is detected, and the electronic device can trigger to start a scanning thread. The electronic device can also acquire the frozen application list through the scanning thread and traverse the frozen applications in the frozen application list.
Then, when the connection of the external storage device is detected, the electronic device can acquire the frozen application. The external storage device is a device which exists outside the electronic device or is embedded in a slot of the electronic device and can be used for storing data, and the common external storage device can be a hard disk, an optical disk, a usb disk, a removable hard disk, a memory card, and the like. The external storage device can be connected with the electronic device and used for expanding the storage capacity of the electronic device. Frozen applications refer to applications that are in a frozen state. The electronic device can monitor the connection state of the external storage device, and when the electronic device detects that the connection of the external storage device exists, the electronic device can acquire the applications in the frozen state in all the applications.
The electronic device may then query the read-write permissions of the frozen application. The read-write permission of the application in the frozen state can also be set by the user through application permission management. After the electronic device acquires the application in the frozen state, the electronic device may also query the read-write permission of the application in the frozen state. The electronic device can obtain the frozen application list and traverse the frozen applications in the frozen application list. The electronic device may obtain the frozen application list, and traverse the frozen applications according to the order arranged in the frozen application list, that is, sequentially access the frozen applications in the frozen application list. The electronic equipment can also obtain a preset application read-write permission table, and the read-write permission of the frozen application is inquired from the application read-write permission table. The application read-write permission table is preset, and the read-write permission table stores read-write permissions of all applications of the electronic equipment, including read-write permission of frozen applications and read-write permission of non-frozen applications. The electronic equipment can acquire a preset application read-write permission table, and the electronic equipment can also inquire the acquired application read-write permission table to acquire the read-write permission of the frozen application.
Secondly, if the frozen application has the read-write permission, the electronic equipment can wake up the frozen application. The read-write authority of the frozen application can be in a forbidden state or an allowed state. And when the read-write authority of the frozen application is in a forbidden state, the frozen application is represented to have no read-write authority, and on the contrary, when the read-write authority of the frozen application is in an allowed state, the frozen application is represented to have the read-write authority. If the frozen application has the read-write permission, the electronic equipment can mark the frozen application. When the inquired frozen application is in a read-write permission state, namely has the read-write permission, the electronic equipment can mark the frozen application with the read-write permission. The electronic device may wake up the frozen application with the flag in the frozen application list. The freezing application with the mark belongs to the freezing application with the read-write permission, and the electronic equipment can wake up the freezing application with the read-write permission.
The electronic equipment can also switch the frozen application from a third-level frozen state to a first-level frozen state or a normal running state, wherein the third-level frozen state is a memory limitation state, the first-level frozen state is a state in which the utilization rate of processor resources is less than a processor resource threshold value, and the normal running state is a state in which the processor resources are not limited. The memory limitation state refers to a state in which the resource memory occupied by the application is limited and the application cannot normally run. The state that the utilization rate of the processor resources is less than the threshold value of the processor resources indicates that the resources used by the application are less than the threshold value of the processor resources, the threshold value of the processor resources is preset, and the threshold value of the processor resources of each application can be different. When the application is in a state where the utilization rate of the processor resources is less than the threshold value of the processor resources, the running of the application is partially limited, which is equivalent to the application being in a light sleep state.
The electronic equipment can also grade the frozen applications according to the read-write permission of the frozen applications to obtain the grades of the frozen applications, and the frozen applications are awakened according to the grades in sequence. Or the electronic device may group the frozen applications according to the association degrees of the frozen applications with the read-write permission to obtain the quantity information of the frozen applications in different groups, and sequentially awaken the applications in different groups according to the sequence from the number of the applications in the frozen application groups to a large number or from a small number to a large number.
And finally, after the unfrozen application scans to obtain the file in the external storage device, the electronic device can freeze the unfrozen application again. The unfrozen application can scan files in the external storage device and load the files into the corresponding unfrozen application. After the unfrozen application scans to obtain the file in the external storage device, the electronic device can perform the re-freezing operation on the unfrozen application.
After the unfrozen application scans to obtain the file in the external storage device, the electronic device can also freeze the unfrozen application according to a preset time interval. The time interval may be preset, and different time intervals may be set for different applications. For example, the time interval of the music playing application may be set to 30 minutes.
