Description

Batch clearing method and device for notification

Technical Field

The present application relates to the field of information processing technologies, and in particular, to a method and an apparatus for batch clearing of notifications.

Background

The notification message of the electronic device needs to be displayed through the notification display center, and the notification display center needs to acquire the notification message which needs to be displayed currently from the notification management center. The information interaction from the notification management center to the notification display center is developed by invoking a binder (a manner of inter-process communication in the Andorid system).

Detailed Description

When batch clearing of notification messages is performed, modules in the electronic device including a notification management center and a notification display center need to quickly delete a large number of notification messages in a short time in response to a batch clearing event. And the information interaction from the notification management center to the notification display center of the electronic device is developed by calling a binder. If a large number of notification messages need to be deleted in a short time, the thread pool of the binder is easily occupied, resulting in a part of processing operation information on the notification messages being lost or an application unresponsive (Application Not Response, ANR) popup window or the like. It should be noted that the batch processing of notification messages described above will result in a large number of operation requests occurring in a short period of time, which may be referred to as a high concurrency scenario for processing notification messages in some embodiments.

The application provides a batch clearing method of notifications, which is applied to first electronic equipment. The first electronic device may be a mobile phone, tablet, desktop, laptop, handheld computer, notebook, smart watch, ultra-mobile personal computer (UMPC), netbook, cell phone, personal digital assistant (personal digital assistant, PDA), augmented reality (augmented reality, AR) \virtual reality (VR) device, media player, television, etc.

For example, taking the example that the first electronic device is the mobile phone 1 as shown in fig. 1A, the status bar interface 10 of the mobile phone 1 may be used to display notification messages from various application programs of the mobile phone 1. Typically, when a notification message exists in the notification bar, a "one-touch-and-clear" control is displayed in the status bar interface 10 of the mobile phone 1, as shown at 101 in fig. 1A. Typically, when the "one-touch clear" control 101 is triggered by the mobile phone 1, the mobile phone 1 needs to quickly clear all notification messages currently displayed. Illustratively, the user activates the "one-touch clear" control 101 and the handset 1 enters the interface shown in the right-hand diagram of fig. 1A after clearing all notification messages currently displayed. It should be appreciated that the control "one-touch clear" described above may also be named "all clear", "clear all notification" and other names. In the following embodiments of the present application, the notification in the mobile phone 1 and the tablet pc 2 is a notification message.

As shown in fig. 1B, the mobile phone 1 includes a first notification display center 102 and a first notification management center 103. In the process of triggering the "one-touch-and-clear" control 101 by the user, the first notification display center 102 sequentially deletes the plurality of first notifications displayed by the first notification display center 102 in response to the event of triggering the "one-touch-and-clear" control 101 by the user. The first notification display center 102 then transmits a clear instruction to the first notification management center 103. After the first notification management center 103 receives the purge instruction, the first notification management center 103 needs to delete the plurality of first notifications stored in the first notification management center 103 in response to the purge instruction.

In the related art, after the first notification management center 103 deletes the plurality of first notifications stored in the first notification management center 103, a message needs to be sent to each module monitoring the first notification management center 103, so as to notify each module monitoring the first notification management center 103 of an event of deleting the plurality of first notifications. The module for monitoring the first notification management center 103 includes the first notification display center 102, and as can be seen from the above description, when the first notification management center 103 sends a message to the first notification display directivity 102, the binder implementation needs to be invoked. Since the user triggers the one-key clearing in the current scenario, the first notification management center 103 deletes a large number of notification messages in a short time, and when the first notification management center 103 sends a message to the first notification display center 102, the thread pool of the binder is easily occupied, so that the problem that part of processing operation information of the notification messages is lost or ANR popup occurs is caused.

The batch clearing method for the notification is applied to the mobile phone 1. The plurality of first notifications displayed at the first notification display center 102 are deleted at the first notification display center 102 of the handset 1 in response to the batch clear event. Then, the first notification display center 102 sends a purge instruction to the first notification management center 103, where the purge instruction carries a first identifier, and the purge instruction is used to indicate that an event corresponding to the initial instruction is a batch purge event. In response to the purge instruction, the first notification management center 103 deletes the plurality of first notifications stored in the first notification management center 103. In addition, in the technical solution provided in the present application, the first notification management center 103 does not notify the first notification display center 102 of the event of deleting the plurality of first notifications based on the clearing instruction carrying the first identifier. Meanwhile, since the first notification display center 102 has deleted the plurality of first notifications prior to the first notification management center 103, the first notification management center 103 does not notify the first notification display center 102 of the event of deleting the plurality of first notifications, nor does it affect the notification message display problem of the mobile phone 1. That is, the first notification display center 102 is prevented from calling the binder to acquire an event of deleting a plurality of first notifications from the first notification management center 103, so that the problem that the binder is full, processing operation information is lost or ANR is generated due to high concurrency of processing notification messages in the scene is solved.

In other embodiments, the mobile phone 1 may also establish a connection with another electronic device (e.g., a second electronic device), and the mobile phone 1 synchronizes the notification of the mobile phone 1 to the second electronic device. The second electronic device may also be a cell phone, tablet, desktop, laptop, handheld computer, notebook, smart watch, UMPC, netbook, as well as a cell phone, PDA, AR/VR device, media player, television, etc. In an embodiment in which the mobile phone 1 synchronizes the notification message in the mobile phone 1 with the second electronic device, please continue to refer to fig. 1B, the mobile phone 1 further includes a first cross-device notification management center 104. The handset 1 may synchronize the notification messages in the handset 1 to the second electronic device through the first cross-device notification management center 104. The specific implementation process of the mobile phone 1 to establish a connection to the second electronic device and the mobile phone 1 to synchronize the notification in the mobile phone 1 to the second electronic device may refer to the description in the related art, which is not repeated in the embodiment of the present application.

Illustratively, as shown in fig. 2A, the mobile phone 1 establishes connection with the tablet computer 2, the notebook computer 3, the smart watch 4, and the like, respectively, and the mobile phone 1 synchronizes notification messages in the mobile phone 1 to the tablet computer 2, the notebook computer 3, the smart watch 4, respectively. In the scenario shown in fig. 2A, the mobile phone 1 may be referred to as a data source (source) for sending data, and the tablet 2, the notebook 3, and the smart watch 4 may be referred to as a data receiving end (sink) for receiving data on the trust ring of the mobile phone 1.

In the scenario shown in fig. 2A, a user processing a notification at source (e.g., deleting the notification) requires immediate synchronization to all sink ends. Similarly, the user processes (e.g., clicks, replies, deletes, etc.) the notification on one of the sink ends, and the sink end needs to synchronize to the source end first, and after the source end processes the notification, the sink end then resynchronizes to the other sink ends. That is, all devices on the trust ring are based on the state of the source end, and if the notification state of the source end is changed, the notification needs to be synchronized to all sink ends, so that the synchronous notification in all sink ends is ensured to be consistent with the notification of the source end.

For example, fig. 2B shows a notification message from the synchronization of the mobile phone 1 displayed on the status bar interface 200 of the tablet 2. Similar to cell phone 1, in the case where tablet 2 has notification messages from cell phone 1 that are synchronized, tablet 2 may also display a "one-touch clear" control 201 on status bar interface 200. The user triggers the "one-touch clear" control 201 on the tablet 2, and the tablet 2 needs to delete all the second notifications synchronized by the mobile phone 1. Meanwhile, the tablet pc 2 also needs to synchronize the notification message deleted in the tablet pc 2 in the mobile phone 1, that is, the tablet pc 2 needs to notify the mobile phone 1 of deleting the notification message.

In this scenario, the first cross-device notification management center 104 of the mobile phone 1 receives the clearing instruction from the tablet computer 2, and the mobile phone 1 deletes a plurality of second notifications in the mobile phone 1, which are synchronized by the mobile phone 1 to the tablet computer 2, according to the clearing instruction. Specifically, after the first cross-device notification management center 104 of the mobile phone 1 receives the purge instruction, the purge instruction is forwarded to the first notification management center 103. In response to the purge instruction, the first notification management center 103 deletes the plurality of second notifications stored in the first notification management center 103. The first notification display center 102 then learns of the event of clearing the plurality of second notifications from the first notification management center 103 by calling the binder. If the number of second notifications is large, the binder may still be full, resulting in a problem that the mobile phone 1 loses the information about the processing operation of part of the second notifications or generates ANR popup.

In the embodiment of the application, a batch clearing method for notification is provided, which is applied to the mobile phone 1. The user triggers a batch purge event when the tablet computer 2 triggers the "one-touch purge" control 201, and after deleting the plurality of second notifications stored in the tablet computer 2, the tablet computer 2 sends a purge instruction to the mobile phone 1. The second notification includes a notification that the mobile phone 1 synchronizes with the tablet computer 2. The first cross-device notification management center 104 of the mobile phone 1 receives the purge instruction from the tablet computer 2, and in response to the purge instruction, the first cross-device notification management center 104 forwards the purge instruction to the first notification management center 103. And the first notification management center 103 deletes the plurality of second notifications stored in the first notification management center 103 in response to the purge instruction. The first notification management center 103 then needs to notify the first notification display center 102 of the event (by calling the binder implementation) to delete the plurality of second notifications. In order to avoid that the binder is full due to high concurrence of processing notification messages, the first notification management center 103 judges the number of the second notifications, and if the number of the second notifications is greater than or equal to the preset number, the first notification management center 103 sends a clearing instruction to the first notification display center 102 every preset time period so as to notify the first notification display center 102 to delete the second notifications corresponding to the preset number. Thus, when the first notification management center 103 notifies the first notification display center 102 of deleting the second notification, a certain time is set between the two clearing instructions, so that the possibility that the binder is full is reduced, and loss of processing operation information or generation of ANR is avoided.

As shown in fig. 2C, in some embodiments, tablet 2 includes a second cross-device notification management center 202, a notification data management center 203, a second notification management center 204, and a second notification display center 205. The process of deleting the plurality of second notifications stored in the tablet computer 2 by the tablet computer 2 includes the following steps in sequence, wherein the user triggers the "one-key clearing" control 201 on the tablet computer 2: the second notification display center 205 deletes the plurality of second notifications, and the second notification management center 204 notifies the second notification display center 205 of an event to delete the plurality of second notifications. The binder implementation also needs to be invoked in the process of the second notification management center 204 notifying the second notification display center 205 of the deletion of the plurality of second notification events. Therefore, in order to avoid situations that the binder is full, the processing operation information is lost, or ANR is generated in the tablet computer 2, the fourth identifier may be carried in the purge instruction sent by the second notification display center 205 to the second notification management center 204, where the fourth identifier is used to indicate that the current purge instruction corresponds to a batch purge event. Further, after the second notification management center 204 deletes the plurality of second notifications, the second notification display center 205 is not notified of the event of deleting the plurality of second notifications. Therefore, the situation that the binder is full, processing operation information is lost or ANR is generated in the 2 of the tablet personal computer due to the batch deletion event can be avoided.

In other embodiments, when the user triggers the "one-touch clear" control 101 on the status bar interface 10 of the mobile phone 1 in fig. 1A, the notifications from the mobile phone 1, including the tablet 2, need to be deleted at each sink end. After the user triggers the "one-touch clear" control 101 of the mobile phone 1, the mobile phone 1 sends a clear instruction to the tablet computer 2 through the first cross-device notification management center 104 to instruct the tablet computer 2 to delete a plurality of first notifications in the tablet computer 2. The second notification management center 204 of the tablet computer 2 needs to invoke the binder to implement the process of deleting the plurality of first notifications from the second notification display center. If the first notification number is large, the binder may be full. In this scenario, therefore, the second notification management center 204 may be restricted to send clear instructions to the second notification display center 205 every preset time period, and each clear instruction is only used to instruct deletion of the notification corresponding to the preset number. In this way, the number of times of calling the binder in a short time is reduced, the possibility that the binder is full in a short time is reduced, and the loss of the processing operation information of the first notification or the generation of ANR in the tablet computer 2 is avoided.

In addition, when any one of the peer devices on the trust ring of the mobile phone 1 is disconnected from the mobile phone 1, the peer device needs to clear the notification from the synchronization of the mobile phone 1. Taking the case that the opposite terminal device is the tablet computer 2 as an example, when the synchronous switch in the mobile phone 1 or the tablet computer 2 is closed or the tablet computer 2 is offline, the disconnection between the mobile phone 1 and the tablet computer 2 is indicated. At this time, the tablet 2 needs to empty all notifications from the handset 1 synchronization.

In this scenario, multiple third notifications from the handset 1 synchronization need to be deleted quickly in a short time in the tablet 2. In the related art, after the second notification management center 204 deletes the plurality of third notifications stored therein, the second notification display center 205 needs to be notified of an event of deleting the plurality of third notifications. This process also requires invocation of the binder implementation, and thus tablet computer 2 is prone to situations in which the binder is full, processing operation information is lost, or ANR is generated.

With continued reference to fig. 2C, the tablet 2 package further includes a cross-device notification status controller 206.

In the embodiment of the application, a batch clearing method for notification is provided, which is applied to the tablet computer 2. The second cross-device notification management center 202 sends a clear instruction to the notification data management center 203 in response to the synchronized disconnection event. The synchronous disconnection event is used for indicating that the mobile phone 1 is disconnected with the tablet computer 2. In response to the purge instruction, the notification data management center 203 deletes the plurality of third notifications stored by the notification data management center 203. Notification data management center 203 then forwards the clear instruction to cross-device notification state controller 206.

In response to the purge instruction, if the number of third notifications is greater than or equal to the preset number, the cross-device notification status controller 206 sends the purge instruction to the second notification management center 204 every preset time period. The second notification management center 204 deletes the third notifications corresponding to the preset number stored in the second notification management center 204 in response to the clearing instruction. The second notification management center 204 then forwards the clear instruction to the second notification display center 205. In response to the clearing instruction, the second notification display center 205 deletes the third notifications corresponding to the preset number displayed by the second notification display center 205.

In the above embodiment, when the cross-device notification status controller 206 sends the clear instruction to the second notification management center 204, if the number of third notifications is greater than or equal to the preset number, the cross-device notification status controller 206 is restricted to send one clear instruction every preset time period, and each clear instruction is used to instruct the second notification management center 204 to delete the preset number of third notifications. Thus, when the second notification management center 204 notifies the second notification display center 205 of the deletion of the third notification after the third notification is deleted, there is not a large amount of third notifications that need to be deleted in a short time. Thereby avoiding the situation that the second notification display center 205 calls the binder to get the event of deleting the third notification from the second notification management center 204, the binder is full, the processing operation information is lost, or ANR is generated.

The batch clearing method for the notification provided by the other embodiment of the application can be applied to the situation that the first electronic device generates the batch clearing event of the notification on the premise that the first electronic device synchronizes the notification in the first electronic device to the second electronic device, and aims at the situation that the binder is occupied in the second electronic device.

The batch clearing method for the notifications provided by the other embodiment of the application can be applied to the scene that the binder is occupied in the second electronic device when the second electronic device is disconnected from the first electronic device on the premise that the first electronic device synchronizes the notifications in the first electronic device to the second electronic device.

Technical terms that may be involved in the present application are described below.

The notification management center refers to a notification manager service (NotificationManager Service, NMS) in the electronic device for storing notifications of the electronic device.

The notification display center refers to a System user interface (System user interface, system UI) in the electronic device, is an application visible to the naked eye of a user in System startup, and has a function of covering everything, such as a screen locking interface seen after startup, a charging interface during charging, a status bar, a navigation bar, a multitasking bar, and the like, which are all functions related to the Android mobile phone user.

Binder is one of the inter-process communication modes of the Android system. In the embodiment of the application, the notification management center and the notification display center of the electronic device respectively belong to two different processes, and the information interaction between the notification management center and the notification display center is realized by calling a binder.

ANR refers to a dialog box that the system displays to the user when the application response is not sensitive enough on the Android system.

In the embodiment of the application, after the mobile phone 1 is connected with the tablet personal computer 2, the notebook computer 3, the intelligent watch 4 and the like, a trust ring of the mobile phone 1 is formed. In the trust ring, the mobile phone 1 is a source terminal, and the tablet computer 2, the notebook computer 3 and the smart watch 4 are sink terminals.

FIG. 4 is a flow chart of a method for batch cleaning of notifications according to an embodiment of the application. In this embodiment, the method is applied to the mobile phone 1, and includes steps S400-S404. Wherein:

s400, detecting batch cleaning events in the mobile phone 1 by the first notification display center.

In some embodiments, the batch clear event corresponds to the user triggering a "one-touch clear" control in the status bar interface of the handset 1. In response to the batch clear event, the handset 1 needs to quickly clear the status bar interface display of multiple notification messages. The "one-touch-and-clear" control is one control in the first notification display center, so that the first notification display center can detect when the user triggers the "one-touch-and-clear" control. In some embodiments, a batch purge event is used to purge all notifications in the status bar of handset 1.

S401, in response to the batch cleaning event, the first notification display center deletes a plurality of first notifications displayed by the first notification display center.

After the batch clear event is detected, the first notification display center needs to delete the plurality of first notifications displayed by the first notification display center. It will be appreciated that after the first notification display center deletes the plurality of first notifications displayed by the first notification display center, the plurality of first notifications will not be displayed on the status bar interface of the mobile phone 1.

In some embodiments, the first notification display center deletes the plurality of first notifications displayed by the first notification display center, and may specifically include: the first notification display center deletes each first notification in turn according to the time sequence of each first notification. For example, the first notification display center sequentially deletes the first notification from "information" shown in fig. 1A, the first notification from "game center", the first notification from "mailbox", and the like from near to far in time.

S402, the first notification display center sends a first clearing instruction to the first notification management center.

In some embodiments, the first purge instruction includes a first flag to indicate that an event corresponding to the first purge instruction is a batch purge event.

In some embodiments, the first notification display center deletes each first notification in turn. For example, after deleting the first notification a, the first notification display center sends a corresponding first clear instruction to the first notification management center, where the first clear instruction is used to instruct the first notification management center to delete the first notification a stored in the first notification management center. Similarly, after deleting the first notification B, the first notification display center sends a corresponding first clearing instruction to the first notification management center, so as to instruct the first notification management center to delete the first notification B. For other first notifications, and so on. Wherein the first clear instruction includes a first identification.

In other embodiments, the first notification display center deletes each first notification sequentially, or may send a first clear instruction to the first notification management center, where the first clear instruction is used to instruct the first notification management center to delete multiple first notifications stored in the first notification management center. That is, the first notification display center transmits only one first clear instruction to the first notification management center in the present embodiment.

S403, the first notification management center receives a first clearing instruction.

S404, in response to the first clearing instruction, the first notification management center deletes a plurality of first notifications stored by the first notification management center.

After the first notification management center receives the first clearing instruction, deleting a plurality of first notifications stored in the first notification management center according to the first clearing instruction.

In the related art, after the first notification management center deletes the plurality of first notifications stored in the first notification management center, it is also necessary to notify each module listening to the first notification management center of an event of deleting the plurality of first notifications. The module also includes a first notification display center. The first notification management center needs to call the binder to realize in the process of notifying the first notification management display center of deleting a plurality of first notifications, and if the number of the first notifications is large, the binder may be occupied in a short time, and the problem of processing operation information loss or ANR generation may occur.

As is clear from S401 described above, in the embodiment of the present application, the first notification display center has deleted the plurality of first notifications displayed by the first notification display center before the first notification management center deletes the plurality of first notifications. The first notification management center receives a first clearing instruction including a first identifier, and the first notification management center can determine that the current deletion of the plurality of first notifications corresponds to a batch clearing event. That is, the first notification management center may determine that the first notification display center has deleted the plurality of first notifications before S404, that is, it is not necessary to notify the event of deleting the plurality of first notifications. Therefore, in order to avoid that the binder is fully occupied in a short time, in the embodiment of the present application, the first notification management center does not notify the first notification display center of an event of deleting the plurality of first notifications after deleting the plurality of first notifications.

According to the technical scheme provided by the embodiment of the application, when a user triggers the one-key clearing control of the mobile phone 1, the first notification management center deletes a plurality of first notifications by setting the first identifier in the clearing instruction sent by the first notification display center to the first notification management center, and then the first notification management center is not informed of the events of the plurality of first notifications. Therefore, the step that the mobile phone 1 needs to call the binder under the batch clearing scene of the notification is canceled, and the problem that the processing operation information of the mobile phone 1 is lost or ANR is generated due to the fact that the binder is occupied is avoided.

Further, the mobile phone 1 may establish a connection with a second electronic device (such as the tablet computer 2), and the mobile phone 1 synchronizes the notification message in the mobile phone 1 with the tablet computer 2 through the first cross-device notification management center. In this scenario, after the mobile phone 1 triggers the "one-touch clear" control, the user needs to delete not only the plurality of first notifications of the mobile phone 1, but also the event of deleting the first notifications to the tablet computer 2, so that the states of the plurality of first notifications in the tablet computer 2 are synchronized with the states of the plurality of first notifications in the mobile phone 1. Referring to fig. 5A, in this embodiment, after S401, the method further includes S501-S503, where:

s501, the first notification display center sends a second clearing instruction to the first cross-device notification management center.

The second clearing instruction is used for instructing the first cross-device notification management center to notify the tablet computer 2 of an event of deleting a plurality of first notifications. In some embodiments, the second purge instruction includes a second identifier, where the second identifier is used to indicate that an event corresponding to the second purge instruction is a batch purge event.

S502, the first cross-device notification management center receives a second clearing instruction.

S503, the first cross-device notification management center forwards a second clearing instruction to the tablet computer 2.

The second clearing instruction is used for instructing the tablet computer 2 to delete a plurality of first notifications stored in the tablet computer 2 and synchronized by the mobile phone 1. The first cross-device notification management center is used for managing relevant information of notification synchronization between other electronic devices (such as the tablet computer 2) in the mobile phone 1. After receiving the second clearing instruction, the first cross-device notification management center forwards the second clearing instruction to the tablet computer 2, and notifies the tablet computer 2 to delete the plurality of first notifications from the mobile phone 1 synchronization. Because the second purge instruction includes the second identifier for indicating the batch purge event, the tablet computer 2 needs to delete the plurality of first notifications stored/displayed in the tablet computer 2 after receiving the second purge instruction.

In some embodiments, there may be a later point in time when the tablet 2 establishes a connection with the handset 1, and the handset 1 will synchronize notifications received in the handset 1 after the point in time when the connection is established with the tablet 2 only after the connection is established with the tablet 2. In this way, only the first notification in part of the handset 1 may be synchronized in the tablet 2. In this scenario, after the first cross-device notification management center of the mobile phone 1 sends the second clearing instruction to the tablet computer 2, the tablet computer 2 deletes all notifications in the tablet computer 2 that the mobile phone 1 synchronizes with the tablet computer 2 according to the second identifier in the second clearing instruction.

In some embodiments, the first cross-device notification management center and the first notification display center belong to the same process, so that the first notification display center sends the second clearing instruction to the first cross-device notification management center, interaction between different processes is not involved, and a process needing to call a binder does not exist. There are no problems that may arise from invoking a binder.

In the technical scheme provided by the embodiment of the application, the first notification display center sends the second clearing instruction to the first cross-device notification management center, so that the first cross-device notification management center notifies each second electronic device to delete a plurality of first notifications, and the state of the first notification in the second electronic device is ensured to be consistent with the state of the first notification in the mobile phone 1.

Further, in some embodiments, S503 specifically refers to forwarding the second clear instruction to the second cross-device notification management center of the tablet computer 2. Referring to fig. 5B, after the second cross-device notification management center of the tablet computer 2 receives the second clear command, steps executed by each module in the tablet computer 2 include S504-S519. In fig. 5B, the "batch clear event occurred in the mobile phone 1" indicates S400 to S404 and S501 to S502. Wherein:

S504, the second cross-device notification management center receives a second cleaning instruction.

S505, responding to the second clearing instruction, and forwarding the second clearing instruction to the notification data management center by the second cross-device notification management center.

S506, notifying the data management center to receive a second clearing instruction.

The notification data management center is used for managing all notification messages in the tablet computer 2, including notification messages synchronized by the mobile phone 1 to the tablet computer 2, notification messages received by the tablet computer 2 locally, and notifications synchronized by other electronic devices to the tablet computer 2.

S507, responding to a second clearing instruction, and deleting a plurality of second notifications stored by the notification data management center.

The plurality of second notifications include all notifications that the mobile phone 1 synchronizes with the tablet 2. In some embodiments, when the mobile phone 1 synchronizes all notifications in the mobile phone 1 with the tablet computer 2, the plurality of second notifications in the tablet computer 2 are all notifications in the mobile phone 1, i.e. the plurality of first notifications. In other embodiments, the mobile phone 1 synchronizes only a part of the notifications in the mobile phone 1 to the tablet computer 2, and then the plurality of second notifications in the tablet computer 2 may also be only a part of the notifications in the mobile phone 1, that is, a part of the notifications in the plurality of first notifications.

In this embodiment, in response to the second clearing instruction, the notification data management center needs to determine which notifications in the tablet computer 2 are notifications that the mobile phone 1 synchronizes with the tablet computer 2, i.e., a plurality of second notifications. Meanwhile, in response to the second purge instruction, the notification data management center deletes the plurality of second notifications stored by the notification data management center.

S508, the notification data management center sends an eleventh clearing instruction to the cross-device notification state controller.

Wherein the cross-device notification manager is configured to forward data and instructions between the notification data management center and the second notification management center. In some embodiments, the eleventh clear instruction includes a plurality of second notifications that need to be deleted. Because of the second notification stored in the tablet 2 that is synchronized by the handset 1 to the tablet 2, it is necessary to screen out all notifications of the tablet 2 by the notification data management center. Thus, after the notification data management center filters and deletes the plurality of second notifications of the notification management center, the eleventh clear instruction sent by the notification data management center to the cross-device notification status controller needs to include the plurality of second notifications for instructing the following modules which notifications to delete.

In some embodiments, the eleventh clear instruction includes notification identifications of the plurality of second notifications. In some embodiments, the notification identifier is used to uniquely identify all notifications stored in the current tablet 2, including notifications local to the tablet 2, and notifications synchronized by the cell phone 1 or other electronic devices in the tablet 2 to the tablet 2. For example, the tablet 2 may set a unique notification identifier for each notification according to notification information such as notification source, time of receiving the notification, and the like.

In other embodiments, the notification identifier is used to distinguish between a local notification stored in the tablet 2, a notification that the handset 1 is synchronized to the tablet 2, a notification that other electronic devices are synchronized to the tablet 2, and so on. Illustratively, a first notification identifier is set in the tablet 2 for notifications synchronized by the mobile phone 1 to the tablet 2, a second notification identifier is set for local notifications, a third notification identifier is set for notifications synchronized by other electronic devices (e.g., a third electronic device) to the tablet 2, and so on.

S509. the cross device informs the state controller to receive the eleventh clear instruction.

S510, the cross-device notification state controller forwards an eleventh clearing instruction to the second notification management center.

S511, the second notification management center receives an eleventh clearing instruction.

S512, responding to the eleventh clearing instruction, and deleting a plurality of second notices stored by the second notice management center.

Since the notification stored in the second notification management center includes not only the notification that the mobile phone 1 in the tablet computer 2 is synchronized to the tablet computer 2, but also the notification that the tablet computer 2 is local. Therefore, the second notification management center needs to delete the notification stored in the second notification management center that the mobile phone 1 is synchronized with the tablet computer 2 in response to the eleventh clear instruction. In some embodiments, the second notification management center deletes the plurality of second notifications of the second notification management center according to the notification identifications of the plurality of second notifications included in the eleventh clear instruction.

S513, the second notification management center judges whether the number of the second notifications is larger than or equal to the preset number.

S514, if yes, the second notification management center sends a twelfth clearing instruction to the second notification display center every preset time period.

The twelfth clearing instruction is used for indicating the second notification display center to delete the second notifications corresponding to the preset number. It will be appreciated that, in the tablet 2, the second notification management center notifies the second notification display center of the event of deleting the second notification, which also needs to be implemented by calling the binder. Therefore, when detecting that the number of second notification is large, in order to avoid that the binder is full in a short time, in the embodiment of the present application, the second notification management center sends a clear command to the second notification display center at intervals of a preset time period.

In some embodiments, the twelfth clear instruction includes notification identifiers of the second notifications corresponding to the preset number to be deleted. The second notification display center can determine which part of the second notification in the second notification display center needs to be deleted according to the preset number of notification identifiers contained in the twelfth clearing instruction.

In some embodiments, the preset time period and the preset number may be set according to actual situations. By way of example, the preset time period may be set to 30 milliseconds (ms), 50ms, 80ms, etc.; the preset number may be set to 5, 10, 15, etc.

S515, the second informing display center receives a twelfth clearing instruction.

S516, responding to a twelfth clearing instruction, and deleting second notices corresponding to the preset quantity displayed by the second notice display center.
