 # Setting Atomic Services to Support Sharing
-By means of sharing, users can quickly access atomic services and use their features.
-
 ## How to Develop
-In the sharing scenario, there are two parties involved: a target application that shares data and an application that obtains the shared data. The two can be physically the same. The target application uses the **onShare()** lifecycle callback to set the data to share. After the target application is started, you can run the **hdc shell aa dump -a** command to check the started services and processes and find its mission ID. After the current application is started, call the **abilityManager.acquireShareData()** API with the mission ID passed in to obtain the shared data.
-> **NOTE**
->
-> The mission ID of the target application can also be obtained by calling [missionManager.getMissionInfos()](../reference/apis/js-apis-app-ability-missionManager.md#getmissioninfos).
 
-1. The target application calls **UIAbility.onShare()** provided by the UIAbility component to set the data to share. **ohos.extra.param.key.contentTitle** indicates the title of the content to share in the sharing box, **ohos.extra.param.key.shareAbstract** provides an abstract description of the content, and **ohos.extra.param.key.shareUrl** indicates the online address of the service. You need to set these three items as objects, with the key set to **title**, **abstract**, and **url**, respectively.
+1. An application calls [UIAbility.onShare()](../reference/apis/js-apis-app-ability-uiAbility.md#onshare), a lifecycle callback provided by the UIAbility component, to set the data to share. In this lifecycle callback, **ohos.extra.param.key.contentTitle** indicates the title of the content to share in the sharing box, **ohos.extra.param.key.shareAbstract** provides an abstract description of the content, and **ohos.extra.param.key.shareUrl** indicates the online address of the service. You need to set these three items as objects, with the key set to **title**, **abstract**, and **url**, respectively.
 
    ```ts
    import AbilityConstant from '@ohos.app.ability.AbilityConstant';
    class MyUIAbility extends UIAbility {
        onShare(wantParams) {
            console.log('onShare');
-           wantParams['ohos.extra.param.key.contentTitle'] = {title: "W3"};
-           wantParams['ohos.extra.param.key.shareAbstract'] = {abstract: "communication for huawei employee"};
-           wantParams['ohos.extra.param.key.shareUrl'] = {url: "w3.huawei.com"};
+           wantParams['ohos.extra.param.key.contentTitle'] = {title: "OA"};
+           wantParams['ohos.extra.param.key.shareAbstract'] = {abstract: "communication for company employee"};
+           wantParams['ohos.extra.param.key.shareUrl'] = {url: "oa.example.com"};
        }
    }
    ```
 
-2. The current application calls **abilityManager.acquireShareData()** to obtain the data shared by the target application. **missionId** indicates the target application's mission ID, which can be obtained by running the **hdc shell aa dump -a** command or calling the **missionManager.getMissionInfos()** API after the target application is started. **wantParam** indicates the data shared by the target application through the **UIAbility.onShare()** lifecycle callback.
+2. A system dialog box calls [abilityManager.acquireShareData()](../reference/apis/js-apis-app-ability-abilityManager.md#acquiresharedata) to obtain data shared through atomic service sharing. Specifically, the system finds the UIAbility based on the mission ID and calls the **OnShare()** lifecycle of the UIAbility to obtain the shared data.

+## Custom Vibration Format
+
+Custom vibration enables you to design desired vibration effects by customizing a vibration configuration file and orchestrating vibration forms based on the corresponding rules.
+
+The custom vibration configuration file is in JSON format. An example file is as follows:
+
+```json

+This JSON file contains two attributes: **MetaData** and **Channels**.
+- **MetaData** contains information about the file header. You can add the following attributes under **MetaData**:
+  - **Version**: version number of the file format, which is forward compatible. Currently, only version 1.0 is supported. This parameter is mandatory.
+  - **ChannelNumber**: number of channels for vibration. Currently, only one channel is supported, and the value is fixed at **1**. This parameter is mandatory.
+  - **Create**: time when the file was created. This parameter is optional.
+  - **Description**: additional information such as the vibration effect and creation information. This parameter is optional.
+- **Channels** provides information about the vibration channel. It is a JSON array that holds information about each channel. It contains two attributes: **Parameters** and **Pattern**.
+- **Parameters** provides parameters related to the channel. Under it, **Index** indicates the channel ID. The value is fixed at **1** for a single channel. This parameter is mandatory.
+  - **Pattern** indicates the vibration sequence. It is a JSON array. Under it, **Event** indicates a vibration event, which can be either of the following types:
+  - **transient**: short vibration
+  - **continuous**: long vibration
+
+The table below describes the parameters under **Event**.
+
+| Parameter| Description| Value or Value Range|
+| --- | ------------------------ | ---|
+| Type | Type of the vibration event. This parameter is mandatory.| **transient** or **continuous**|
+| StartTime | Start time of the vibration. This parameter is mandatory.| [0, 1800 000], in ms, without overlapping|
+| Duration | Duration of the vibration. This parameter is valid only when **Type** is **continuous**.| (10, 1600), in ms|
+| Intensity | Intensity of the vibration. This parameter is mandatory.| [0, 100], a relative value that does not represent the actual vibration strength.|
+| Frequency | Frequency of the vibration. This parameter is mandatory.| [0, 100], a relative value that does not represent the actual vibration frequency|
+
+The following requirements must be met:
+
+| Item| Description                |

+# @ohos.resourceschedule.deviceStandby (Device Standby)
+A device enters standby mode if it is unused for a long period of time or after the Power button is pressed. The standby mode prolongs the battery life without affecting the use of applications. The **deviceStandby** module provides APIs for you to check whether a device is in standby mode and request or cancel standby resource control for an application.
+
+>  **NOTE**
+>   
+> The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.

 - **Quota mechanism**: To prevent abuse of the keepalive, each application has a certain quota every day (dynamically adjusted based on user habits). The default quota for a single day is 10 minutes, and the maximum quota for each request is 3 minutes. After using up the quota, an application cannot request transient tasks. Therefore, applications should cancel their request immediately after the transient tasks are complete, to avoid quota consumption. (Note: The quota refers to the requested duration and does not include the time when the application runs in the background.)
 
 ## Continuous Tasks

 Continuous tasks provide background running lifecycle support for services that can be directly perceived by users and need to run in the background. For example, if a service needs to play audio or continue with navigation and positioning in the background, which can be perceived by users, it can execute a continuous task in the respective background mode.

 - If a user triggers a perceivable task, such as broadcasting and navigation, the corresponding background mode is triggered. When the task is started, the system forcibly displays a notification to the user.
 - If the task is complete, the application should exit the background mode. If the system detects that an application is not using the resources in the corresponding background mode when the application is running in the background, the application is suspended.
 - Ensure that the requested continuous task background mode matches the application type. If the background mode does not match the application type, the system will suspend the task once it detects the issue.

 ## Work Scheduler Tasks
+
 The Work Scheduler provides a mechanism for an application to execute a non-real-time task, for example, data learning, when the system is idle. The system places the Work Scheduler tasks requested by applications in a queue and determines the optimal scheduling time of each task based on the storage space, power consumption, temperature, and more. Persistence is supported. This means that a requested Work Scheduler task can be triggered when the application exits or the device restarts.

 ### Restrictions on Using Efficiency Resources
+
 - Applications or processes are responsible for requesting and releasing efficiency resources. A process can release the resources requested by itself, whereas an application can release the resources requested by both itself and its processes. For example, an application requests CPU resources, and its process requests CPU and WORK_SCHEDULER resources. If the application initiates CPU resource release, the CPU resources requested by the process are also released. However, the WORK_SCHEDULER resources are not released. If the process initiates CPU resource release, the CPU resources requested by the application are retained until being released by the application.
 - If persistent resources and non-persistent resources of the same type are requested, the persistent resources overwrite the non-persistent resources and they will not be released upon a timeout. For example, if an application first requests 10-second CPU resources and then requests persistent CPU resources at the 5th second, the CPU resources become persistent and will not be released at the tenth second. If the application releases the CPU resources at the 8th second, both types of CPU resources are released.
 - The WORK_SCHEDULER resources can be requested and released by applications, but not by processes.

+## cl.vibrator.1 Added Attributes Related to Custom Vibration
+
+The attributes **VibrateFromFile** (custom vibration effect) and **HapticFileDescriptor** (file descriptor of the custom vibration configuration file) are added. The vibration effect supported by **startVibration** is extended from **VibrateEffect = VibrateTime | VibratePreset** to **VibrateEffect = VibrateTime | VibratePreset | VibrateFromFile**.
+
+**Change Impact**
+
+When developing applications based on OpenHarmony4.0.8.2 and later SDK versions, you can use the **VibrateFromFile** attribute to enable devices that support custom vibration to trigger vibration according to the vibration sequence configured in the custom vibration configuration file.
+
+**Key API/Component Changes**
+
+Added the **VibrateFromFile** and **HapticFileDescriptor** attributes to **@ohos.vibrator.d.ts**.
+
+| Module| Class| Method/Attribute/Enum/Constant| Change Type|
+|  -- | -- | -- | -- |
