The words "first" and "second" do not limit the number and execution order, and the words "first" and "second" do not necessarily mean that they must be different.

In addition, in the embodiment of the present application, for a technical feature, the technical features of this technical feature are distinguished by "first", "second", "third", etc., the "first", "second" ", "Third" describes the technical features in no order or order of magnitude.

It can be understood that, in the embodiments of the present application, the same step or steps or technical features having the same function can be used for reference in different embodiments.

It can be known from the description in the background that, in the case of multiple applications running on the electronic device, if the memory of the electronic device is insufficient, the electronic device will kill some of the applications. Therefore, if the application in the electronic device is to be kept alive, how to increase the memory through software technology on the limited memory of the electronic device is very important. For example, an increase in memory can be achieved by the method described below.

Method 1: Fix a piece of memory in the memory of the electronic device as a compressed memory (zip random access memory, zRAM) buffer. The electronic device can gradually compress the data of inactive applications in the memory of the electronic device, and store the compressed data in the zRAM buffer. In this way, the electronic device can release a part of the memory by compressing the data, so that the applications in the electronic device can be kept alive. Subsequently, if the electronic device needs to use the data, the data is decompressed.

As shown in FIG. 1A , a memory 103 is fixed in the memory 101 of the electronic device as a zRAM buffer. The remaining memory, memory 102, can be used to store data. In FIG. 1A , before the data in the memory 102 is compressed, data of inactive applications and data of active applications are stored, and the memory 102 is already full. By compressing the data of inactive applications and storing the compressed data in the zRAM buffer, the memory 102 has free memory space. In this way, there is no need to kill the application, and the application in the electronic device can be kept alive.

In this embodiment of the present application, the inactive application may be any application running in the background of the electronic device. For example, an inactive application may be an application that is not used by a user for a period of time among the applications running in the background of the electronic device. The active application may be an application running in the foreground of the electronic device, or the active application may be an application frequently used by the user among the applications running in the background of the electronic device.

Method 2: Extended on the basis of Method 1. As shown in FIG. 1B , after the electronic device compresses the data of inactive applications, it writes part of the compressed data in the zRAM buffer into the flash memory (flash memory) according to the memory usage of the electronic device. In this way, the memory of the electronic device can be saved, and the applications in the electronic device can be kept active. Subsequently, if the electronic device needs to use the data, the data is read from the flash memory.

Method 3: The electronic device can obtain information about other electronic devices connected to it, and determine whether the other electronic devices can assist the electronic device in implementing application keep-alive according to the information of the other electronic devices. If the other electronic device can assist the electronic device to keep the application alive, send the data of the inactive application on the electronic device to the other electronic device, and delete the data of the inactive application on the electronic device. In this way, the electronic device can release a part of the memory, so that the applications on the electronic device can be kept alive. The specific process of method 3 will be described in detail in the method shown in FIG. 5 below, and will not be repeated here.

Understandably, compared with methods 1 and 2, method 3 does not need to fix a block of memory as a zRAM buffer, that is, the electronic device of method 3 can control all the memory, which improves the utilization rate of memory. In addition, compared with method 1, the memory of other electronic devices in method 3 is much larger than the zRAM buffer, therefore, it can assist the electronic device to keep more applications alive. Compared with method 2, in method 3, the read and write life of memory of other electronic devices is not limited like flash memory. Therefore, when using method 3 to increase memory, there is no need to consider the life of the device, and the implementation is simple and convenient.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, technical terms involved in the embodiments of the present application are explained below.

In the embodiment of this application, the following three situations may occur when electronic devices exchange data:

1. Anonymous page whole block read (anonymous page-whole blok read, ap-wbr)

AP-WBR can be performed in situations where data on one electronic device needs to be written to another electronic device. This process is not perceived by the user. As shown in FIG. 1C , electronic device 1 may send data of inactive applications in its memory (such as multiple anonymous pages corresponding to inactive applications) to electronic device 2 . After receiving the data of the inactive application, the electronic device 2 writes these data into the memory of the electronic device 2 . In this way, the electronic device 1 can delete the data of the inactive application, so that the memory of the electronic device 1 has more free storage space.

It can be understood that after the electronic device 1 deletes the data of the inactive application, the process of the inactive application is frozen and cannot be scheduled. If a certain process of the application needs to be scheduled, the anonymous page corresponding to the process needs to be obtained from the electronic device 2.

2. Anonymous page fault (anonymous page-fault, ap-fault) write

AP-fault writes can be performed without the electronic device having access to the data. This process is not perceived by the user. As shown in Figure 1D, electronic device 1 sends multiple anonymous pages corresponding to inactive applications to electronic device 2, and after deleting these anonymous pages, if you want to schedule individual processes of the inactive application (such as WeChat

Some processes need to be regularly scheduled to receive messages from the cloud), then the electronic device 2 can send the anonymous page corresponding to the process to the electronic device 1, so that the electronic device 1 can run the process.

3. Anonymous page-whole blok write (anonymous page-whole blok write, ap-wbw)

The ap-wbw can be performed when an application running in the background of the electronic device switches to running in the foreground. In this case, the electronic device may acquire the anonymous page corresponding to the application from the electronic device storing the anonymous page corresponding to the application, so that the electronic device runs the application. For example, as shown in FIG. 1E , after the electronic device 2 sends individual anonymous pages to the electronic device 1 , the inactive application switches from the background of the electronic device 1 to the foreground. In this case, electronic device 2 may send the remaining anonymous pages in the entire block of anonymous pages to electronic device 1, so that electronic device 1 can run the application.

It is understandable that users are aware of the process of ap-wbw. If an application running in the background on an electronic device is switched to running in the foreground, if the electronic device obtains the anonymous page corresponding to the application from other electronic devices too slowly, it will cause the application The response is too slow, which affects the user experience.

The implementation of the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

It can be understood that the first electronic device may delete the data of the first application from the memory of the first electronic device, so that the memory of the first electronic device has more free storage space. In this way, the first electronic device does not need to kill the application, and the application in the first electronic device can be kept alive.

Based on the method shown in Figure 5, the first electronic device sends the data of the first application to the second electronic device under the condition that the second electronic device can assist the first electronic device in keeping the application alive, so that the first electronic device can share memory of the second electronic device. Therefore, the first electronic device can release the data of the first application to obtain more free storage space. This prevents the background application of the first electronic device from being killed due to insufficient running memory, realizes application keeping alive, and improves user experience. In addition, the method shown in FIG. 5 does not require any modification or adaptation to the application on the first electronic device, and is simple to operate and convenient to use.

Optionally, after S503, if the first application is switched to run in the foreground of the first electronic device, the first electronic device may obtain the data of the first application from the second electronic device, so that the first application is in the foreground of the first electronic device run. For example, the method shown in FIG. 5 further includes S504-S505.

S504: The first electronic device sends first request information to the second electronic device. Correspondingly, the second electronic device receives the first request information from the first electronic device.

In this embodiment of the present application, the first request information may be used to request data of the first application. For example, the first request information may include the identifier of the anonymous page corresponding to the first application. In this way, after receiving the first request information, the second electronic device may acquire the anonymous page corresponding to the first application (ie, the data of the first application) according to the identifier of the anonymous page corresponding to the first application.

S505: The second electronic device sends data of the first application to the first electronic device. Correspondingly, the first electronic device receives data from the first application of the second electronic device.

In this embodiment of the present application, the data of the first application sent by the second electronic device to the first electronic device may also be referred to as ap-wbw. The introduction of ap-wbw can refer to the above.

Optionally, after S502, the first electronic device continues to send data of applications on the first electronic device to the second electronic device, so that the first electronic device can release more memory. For example, the method shown in FIG. 5 further includes S506.

S506: The first electronic device sends the data of the second application to the second electronic device. Correspondingly, the second electronic device receives data from the second application of the first electronic device.

In this embodiment of the present application, the second application may be an application in at least one application running on the first electronic device. The second application runs in the background of the first electronic device.

It can be understood that the data of the second application may be sent to the second electronic device, and may also be sent to other devices that meet the conditions indicated by the preset information, without limitation.

Optionally, after S506, if the first electronic device needs to schedule some processes of the second application, the first electronic device may obtain anonymous pages corresponding to these processes from the second electronic device. For example, the method shown in FIG. 5 further includes S507-S508.

S507: The first electronic device sends second request information to the second electronic device. Correspondingly, the second electronic device receives the second request information from the first electronic device.

In this embodiment of the application, the second request information may be used to request the first data. For example, the second request information may include the identifier of the anonymous page corresponding to the first data. In this way, after receiving the second request information, the second electronic device may acquire the first data according to the identifier of the anonymous page corresponding to the first data. Wherein, the first data is part of the data of the second application. For example, the first data is an anonymous page corresponding to a partial process of the second application.

S508: The second electronic device sends the first data to the first electronic device. Correspondingly, the first electronic device receives the first data from the second electronic device.

In this embodiment of the present application, sending the first data from the second electronic device to the first electronic device may also be referred to as ap-fault writing. For the introduction of ap-fault writing, please refer to the above.

It can be understood that, in this embodiment of the present application, if multiple applications are running on the first electronic device, ap-wbr, ap-fault writing, and ap-wbw may occur simultaneously. As can be seen from the previous description, the user is not aware of the writing of ap-wbr and ap-fault. However, users are aware of ap-wbw. If ap-wbw cannot be executed in time, the application response will be too slow and user experience will be affected. Therefore, different priorities can be configured for ap-wbr, ap-fault write, and ap-wbw, so that operations with higher priority can be executed first to improve user experience.

In a possible implementation, the priority of ap-wbw is higher than that of ap-wbr and ap-fault.

The priority of ap-fault writing is higher than that of ap-wbr. In this way, the ap-wbw can be executed preferentially, the interference during the execution of the ap-wbw can be reduced, and the execution efficiency of the ap-wbw can be improved. Then, after the application is switched from the background to the foreground, the first electronic device can obtain the data of the application in time, and run the application in the foreground in time, so as to improve user experience.

As an example, if ap-wbr, ap-fault writing and ap-wbw occur at the same time, ap-wbw is executed first, and ap-wbr and ap-fault writing are set to wait for a timeout. After waiting for a timeout, execute ap-wbr and ap-fault.

As another example, if ap-wbr, ap-fault write, and ap-wbw occur at the same time, ap-wbw is executed first, and ap-wbr and ap-fault write are set to wait. Execute ap-wbr and ap-fault after ap-wbw is executed.

As another example, if ap-wbr, ap-fault write and ap-wbw occur at the same time, ap-wbw is executed first, ap-fault write is set to timeout wait, and ap-wbr is set to wait. Subsequently, after waiting for the timeout, execute ap-fault write, and execute ap-wbr after the execution of ap-wbw is completed.

It can be understood that, in the above example, if ap-wbw and ap-fault writing correspond to the same application, execution of ap-fault writing can be stopped and ap-wbw can be executed. Because the data written by the ap-fault is included in the data of the ap-wbw, the first electronic device can obtain the data obtained when the ap-fault write is executed by executing the ap-wbw. Use ap-wbw and ap-fault to write the corresponding application as WeChat

For example, WeChat

After switching from the foreground of the first electronic device to the background, the first electronic device can send WeChat

The data is sent to the second electronic device. After that, if WeChat

Some processes need to be scheduled to receive messages from the cloud, and the first electronic device can execute ap-fault writing. In the process of executing ap-fault writing on the first electronic device, if WeChat

Switching from the background of the first electronic device to the foreground, the first electronic device may stop executing ap-fault writing, but execute ap-wbw instead.

Taking the method shown in FIG. 5 including S504-S508 at the same time as an example, the execution sequence of ap-wbr, ap-fault writing and ap-wbw will be introduced below.

In a possible implementation manner, the priority of the first operation is higher than the priorities of the second operation and the third operation. The priority of the third operation is higher than that of the second operation. Wherein, the first operation is that the first electronic device receives data from the first application of the second electronic device. The second operation is that the first electronic device sends the data of the second application to the second electronic device. The third operation is that the first electronic device receives the first data from the second electronic device.

Exemplarily, as shown in FIG. 6A, if the first electronic device needs to perform the first operation during the process of performing the second operation and the third operation (that is, during the process of performing S505 and S508, the first electronic device needs to perform S505 ), the first electronic device preferentially executes the first operation, and sets the second operation and the third operation as timeout waiting. After waiting for timeout, execute the second operation and the third operation.

Exemplarily, as shown in FIG. 6B, if the first electronic device needs to perform the first operation during the process of performing the second operation and the third operation, the first electronic device will perform the first operation first, and the second operation And the third action is set to wait. After the first operation is executed, the second operation and the third operation are executed.

Exemplarily, as shown in FIG. 6C, if the first electronic device needs to perform the first operation during the process of performing the second operation and the third operation, the first electronic device performs the first operation first, and sets the third operation to Wait for a timeout and set the second action to wait. Subsequently, after waiting for a timeout, the third operation is performed, and the second operation is performed after the first operation is completed.

It can be known from the foregoing description that the time spent on ap-wbw is closely related to user experience. The shorter the time spent in ap-wbw, the better the user experience. In order to further improve user experience, different transmission channels can be established for ap-wbr, ap-fault write and ap-wbw respectively. In this way, ap-wbr, ap-fault write, and ap-wbw can process data through their own transmission channels without affecting each other.

Optionally, before S505, the first electronic device and the second electronic device establish a first channel. Wherein, the first channel is used to transmit application data stored in the second electronic device and on the first electronic device. In this way, the second electronic device can send the data of the first application to the first electronic device through the first channel, and the first electronic device can receive the data of the first application through the first channel. For example, before S505, the first electronic device and the second electronic device establish a first transmission control protocol (transmission control protocol, TCP) connection, and establish a first thread. The first TCP connection and the first thread may be used to transmit data of an application stored in the second electronic device on the first electronic device.

Optionally, before S508, the first electronic device and the second electronic device establish a second channel. Wherein, the second channel is used to transmit part of the data stored in the second electronic device and the application data on the first electronic device. In this way, the second electronic device can send the first data to the first electronic device through the second channel, and the first electronic device can receive the first data through the second channel. For example, before S508, the first electronic device and the second electronic device establish a second TCP connection, and establish a second thread. The second TCP connection and the second thread may be used to transmit part of the data stored in the second electronic device and the data of the application on the first electronic device.

Optionally, before S502, the first electronic device and the second electronic device may establish a third channel. Wherein, the third channel may be used to transmit application data on the first electronic device. In this way, the first electronic device can send the data of the first application to the second electronic device through the third channel, and the second electronic device can receive the data of the first application through the third channel. For example, before S502, the first electronic device and the second electronic device establish a third TCP connection, and establish a third thread. The third TCP connection and the third thread can be used to transmit data of the application on the first electronic device.

Understandably, in order to improve user experience, different priorities may be configured for the first thread, the second thread, and the third thread according to the user's sensitivity to ap-wbw, ap-wbr, and ap-fault writes. Threads with higher priority can be processed earlier. As mentioned above, users are not aware of ap-wbr and ap-fault writing, but are aware of ap-wbw. If ap-wbw cannot be executed in time, the application response will be too slow and user experience will be affected. Therefore, the priority of the first thread may be higher than the priority of the second thread and the priority of the third thread. The priority of the second thread is higher than the priority of the third thread, or the priority of the second thread is the same as that of the third thread.

Understandably, in order to save transmission resources, a transmission channel may be established for ap-wbr and ap-fault writing, and ap-wbr and ap-fault writing may process data through this transmission channel. For example, before S502, the first electronic device and the second electronic device may establish a fourth channel. The fourth channel may have the functions of the above-mentioned second channel and third channel.

Understandably, in order to further increase the speed of ap-wbr, ap-fault writing, and ap-wbw, data sending and receiving and data processing can be decoupled, so that data sending and receiving and data processing do not affect each other. In this way, the first electronic device or the second electronic device can continuously receive or send data, so that the data transmission rate can be kept at the highest level without interrupting the sending and receiving operation due to data processing.

Exemplarily, the first electronic device and the second electronic device may establish independent transmission channels, independent data sending and receiving tasks, and independent data processing tasks for ap-wbr, ap-fault writing, and ap-wbw. As shown in FIG. 7 , the first electronic device can establish data processing task 1, data processing task 2, data sending task 1, data receiving task 1 and data receiving task 2. The second electronic device can establish the data receiving task 3, the data sending task 2 and the data sending task 3, and the memory buffer in the second electronic device can be used to store the application data in the first electronic device. Wherein, the data processing task 1 may send data applied in the first electronic device, and the data applied in the first electronic device may be transmitted to the second electronic device through a third channel. The data receiving task 3 can receive the data of the application in the first electronic device. After receiving the application data in the first electronic device, the second electronic device may write the data into the memory buffer. Subsequently, if the application 1 on the first electronic device is switched from the background to the foreground, the data sending task 2 can send the data of the application 1, and the data of the application 1 can be transmitted to the first electronic device through the first channel. The data receiving task 1 can receive the data of the application 1, and notify the data processing task 1 to process the data of the application 1. The data processing task 1 may store the data of the application 1 in the memory of the first electronic device. If the first electronic device needs to schedule part of the process of the application 2, the data sending task 3 can send the data required by the part of the process of the application 2, and the data required by the part of the process of the application 2 can be transmitted to the first electronic device through the second channel. The data receiving task 2 may receive data required by some processes of the application 2, and notify the data processing task 2 to process the data. The data processing task 2 may store the data in the memory of the first electronic device.

Optionally, a full index mechanism is constructed for the memory buffer of the second electronic device. That is to say, after the second electronic device receives and stores the application data of the first electronic device, it will not modify, delete or add the stored data until the second electronic device sends all the application data to the second electronic device. an electronic device. For example, the second electronic device executes ap-wbr, receives and stores the data of application 1 from the first electronic device, and then executes ap-fault writing to send the 4k data in application 1 to the first electronic device. Afterwards, the second electronic device does not delete the 4k data. Subsequently, if the application 1 is switched from the background of the first electronic device to the foreground, the second electronic device executes ap-wbw, sends the data of the application 1 to the first electronic device, and deletes the data of the application 1. In this way, conflicts between reading and writing data of the same application can be avoided, so that the reading and writing operations of data are independent of each other and do not affect each other. For example, in the case of the same application, the second electronic device performs ap-fault writing multiple times, if the second electronic device deletes the data sent to the first electronic device after each execution of ap-fault writing, it will As a result, subsequent ap-fault write operations cannot find the corresponding data, which affects subsequent ap-fault write operations.

Optionally, the first electronic device may obtain the information of the second electronic device from the second electronic device, or obtain the information of the second electronic device locally. For example, as shown in FIG. 8, S501 includes S5011 or S5012.

S5011: The first electronic device receives information from the second electronic device of the second electronic device.

In a possible implementation manner, the first electronic device triggers the second electronic device to send the information about the second electronic device. That is to say, when the first electronic device needs to keep alive the application, the first electronic device may send the third request information to the second electronic device. After receiving the third request information, the second electronic device sends response information to the first electronic device, where the response information includes information of the second electronic device. In this embodiment of the present application, the fact that the first electronic device needs to perform application keep-alive may be understood as: the available memory of the first electronic device is less than or equal to the first threshold. That is to say, when the available memory of the first electronic device is insufficient, the first electronic device can execute the data processing method provided by the embodiment of the present application, so that the first electronic device can share the memory of the second electronic device to realize application keep alive. In this embodiment of the present application, the third request information may also be referred to as a find device request (FindDeviceRequest) message. The third request information may be used to request information of the second electronic device.

It can be understood that, for the above case 1, the second electronic device may send the information in the information of the second electronic device to the first electronic device in multiple times.

As an example, after receiving the third request information, the second electronic device may first send response information 1 to the first electronic device, where the response information 1 includes the identifier of the second electronic device. Subsequently, the second electronic device sends response information 2 to the first electronic device, where the response information 2 includes information about the available memory of the second electronic device.

As another example, after receiving the third request information, the second electronic device may first send a device information response (DeviceInfoResponse) message to the first electronic device, where the device information response message includes at least one item of device information, for example including The identifier of the second electronic device and the IP address of the second electronic device. After receiving the device information response message, the first electronic device sends a device resource request (GetDeviceResourceRequest) message to the second electronic device. After receiving the device resource acquisition request message, the second electronic device sends a device resource response (DeviceResourceResponse) message to the first electronic device, and the device resource response message includes at least one item of device resource information, for example, the second electronic device's available The indication information of the internal memory, the indication information of whether the second electronic device is in an active state, and the indication information of the remaining power of the second electronic device. For the introduction of device information and device resource information, reference may be made to the above S501.

Optionally, the third request information is also used to subscribe to information of the second electronic device. Subsequently, if the information of the second electronic device changes, for example, the IP address of the second electronic device changes, the second electronic device may send the first update information to the first electronic device. The first update information includes updated information of the second electronic device, for example, an updated IP address. Similarly, the device resource acquisition request message in the above example is also used to subscribe to device resource information. Subsequently, if the device resource information of the second electronic device changes, the second electronic device may send second update information to the first electronic device, where the second update information includes updated device resource information.

S5012: The first electronic device acquires the information of the second electronic device locally.

In a possible implementation manner, the second electronic device periodically sends the information of the second electronic device to the first electronic device. After receiving the information of the second electronic device, the first electronic device stores the information of the second electronic device locally. In the case that the first electronic device needs to keep the application alive, the first electronic device acquires the latest received information of the second electronic device locally.

In another possible implementation manner, after establishing a connection with the first electronic device, the second electronic device sends information about the second electronic device to the first electronic device. Subsequently, if the information of the second electronic device changes, the second electronic device sends third update information to the first electronic device, where the third update information includes updated information of the second electronic device. In the case that the first electronic device needs to keep the application alive, the first electronic device acquires the latest received information of the second electronic device locally.

It can be understood that the data processing method provided by the embodiment of the present application is to send the data of the application in the first electronic device to the second electronic device, so that the second electronic device can assist the first electronic device in storing the data of the application, realizing the electronic device memory sharing among them. Based on this idea, computing resources can also be shared between electronic devices. For example, the first electronic device may divide the calculation task into multiple subtasks, and assign the multiple subtasks to at least one second electronic device, so that the at least one second electronic device assists the first electronic device to complete the calculation task. In this way, computational efficiency can be improved. Among them, the computing task may be graphics rendering, video clipping, and the like.
