An ability is the abstraction of a functionality that an application can provide. It is the minimum unit for the system to schedule applications. An application can contain one or more `Ability` instances.
The ability framework model has two forms.
The ability framework model has two forms:
- FA model, which applies to application development using API version 8 and earlier versions. In the FA model, there is Feature Ability (FA) and Particle Ability (PA). The FA supports Page abilities, and the PA supports Service, Data, and Form abilities.

The OpenHarmony application framework has two models: Feature Ability (FA) model and stage model. Correspondingly, there are two sets of context mechanisms. **application/BaseContext** is a common context base class. It uses the **stageMode** attribute to specify whether the context is used for the stage model.
- FA model
Only the methods in **app/Context** can be used for the context in the FA model. Both the application-level context and ability-level context are instances of this type. If an ability-level method is invoked in the application-level context, an error occurs. Therefore, you must pay attention to the actual meaning of the **Context** instance.
- Stage model
The stage model has the following types of contexts: **application/Context**, **application/ApplicationContext**, **application/AbilityStageContext**, **application/ExtensionContext**, **application/AbilityContext**, and **application/FormExtensionContext**. For details about these contexts and how to use them, see [Context in the Stage Model](#context-in-the-stage-model).

# ContinuationManager Development
> **NOTE**
>
> Currently, the **ContinuationManager** module is not available for application development. Its APIs are mainly used to start the device selection module.
## When to Use
Users are using two or more devices to experience an all-scenario, multi-device lifestyle. Each type of device has its unique advantages and disadvantages specific to scenarios. The ability continuation capability breaks boundaries of devices and enables multi-device collaboration, achieving precise control, universal coordination, and seamless hops of user applications.
As the entry of the ability continuation capability, **continuationManager** is used to start the device selection module for the user to select the target device. After a device is selected, information about the selected device is returned to the user. The user can then initiate cross-device continuation or collaboration based on the device information.

## How to Develop
1. Import the **continuationManager** module.
```ts
import continuationManager from '@ohos.continuation.continuationManager';
```
2. Apply for permissions required for cross-device continuation or collaboration operations.
The permission application operation varies according to the ability model in use. In the FA mode, add the required permission in the `config.json` file, as follows:
```json
{
"module": {
"reqPermissions": [
{
"name": "ohos.permission.DISTRIBUTED_DATASYNC"
}
]
}
}
```
This permission must also be granted by the user through a dialog box when the application is started for the first time. The sample code is as follows:
```ts
import abilityAccessCtrl from "@ohos.abilityAccessCtrl";
import bundle from '@ohos.bundle';
async function requestPermission() {
let permissions: Array<string> = [
"ohos.permission.DISTRIBUTED_DATASYNC"
];
let needGrantPermission: boolean = false;
let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
let applicationInfo = await bundle.getApplicationInfo('ohos.samples.etsDemo', 0, 100);
for (let i = 0; i < permissions.length; i++) {
let result = await atManager.verifyAccessToken(applicationInfo.accessTokenId, permissions[i]);
// Check whether the permission is granted.
if (result == abilityAccessCtrl.GrantStatus.PERMISSION_GRANTED) {
needGrantPermission = true;
break;
}
}
// If the permission is not granted, call requestPermissionsFromUser to apply for the permission.
if (needGrantPermission) {
await featureAbility.getContext().requestPermissionsFromUser(permissions, 1);
} else {
console.info('app permission already granted');
}
}
```
In the stage model, add the required permission in the `module.json5` file. The sample code is as follows:
```json
{
"module": {
"requestPermissions": [
{
"name": "ohos.permission.DISTRIBUTED_DATASYNC"
}
]
}
}
```
```ts
import abilityAccessCtrl from "@ohos.abilityAccessCtrl";
import bundle from '@ohos.bundle';
async function requestPermission() {
let permissions: Array<string> = [
"ohos.permission.DISTRIBUTED_DATASYNC"
];
let needGrantPermission: boolean = false;
let atManger: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
let applicationInfo = await bundle.getApplicationInfo('ohos.samples.continuationmanager', 0, 100);
for (const permission of permissions) {
try {
let grantStatus = await atManger.verifyAccessToken(applicationInfo.accessTokenId, permission);
// Check whether the permission is granted.
if (grantStatus === abilityAccessCtrl.GrantStatus.PERMISSION_DENIED) {
needGrantPermission = true;
break;
}
} catch (err) {
console.error('app permission query grant status error' + JSON.stringify(err));
needGrantPermission = true;
break;
}
}
// If the permission is not granted, call requestPermissionsFromUser to apply for the permission.
if (needGrantPermission) {
try {
await globalThis.abilityContext.requestPermissionsFromUser(permissions);
} catch (err) {
console.error('app permission request permissions error' + JSON.stringify(err));
}
} else {
console.info('app permission already granted');
}
}
```
3. Register the continuation management service and obtain a token.
The sample code is as follows:
```ts
let token: number = -1; // Used to save the token returned after the registration. The token will be used when listening for device connection/disconnection events, starting the device selection module, and updating the device connection state.
continuationManager.register().then((data) => {
console.info('register finished, ' + JSON.stringify(data));
token = data; // Obtain a token and assign a value to the token variable.
}).catch((err) => {
console.error('register failed, cause: ' + JSON.stringify(err));
});
```
4. Listen for the device connection/disconnection state.
The sample code is as follows:
```ts
let remoteDeviceId: string = ""; // Used to save the information about the remote device selected by the user, which will be used for cross-device continuation or collaboration.
// The token parameter is the token obtained during the registration.
continuationManager.on("deviceConnect", token, (continuationResults) => {
console.info('registerDeviceConnectCallback len: ' + continuationResults.length);
if (continuationResults.length <= 0) {
console.info('no selected device');
return;
}
remoteDeviceId = continuationResults[0].id; // Assign the deviceId of the first selected remote device to the remoteDeviceId variable.
// Pass the remoteDeviceId parameter to want.
let want = {
deviceId: remoteDeviceId,
bundleName: 'ohos.samples.continuationmanager',
abilityName: 'MainAbility'
};
// To initiate multi-device collaboration, you must obtain the ohos.permission.DISTRIBUTED_DATASYNC permission.
globalThis.abilityContext.startAbility(want).then((data) => {
console.info('StartRemoteAbility finished, ' + JSON.stringify(data));
}).catch((err) => {
console.error('StartRemoteAbility failed, cause: ' + JSON.stringify(err));
});
});
```
The preceding multi-device collaboration operation is performed across devices in the stage model. For details about this operation in the FA model, see [Page Ability Development](https://gitee.com/openharmony/docs/blob/master/en/application-dev/ability/fa-pageability.md).
You can also instruct the device selection module to update the device connection state. The sample code is as follows:
```ts
// Set the device connection state.
let deviceConnectStatus: continuationManager.DeviceConnectState = continuationManager.DeviceConnectState.CONNECTED;
// The token parameter is the token obtained during the registration, and the remoteDeviceId parameter is the remoteDeviceId obtained.
continuationManager.updateConnectStatus(token, remoteDeviceId, deviceConnectStatus).then((data) => {
console.info('updateConnectStatus finished, ' + JSON.stringify(data));
}).catch((err) => {
console.error('updateConnectStatus failed, cause: ' + JSON.stringify(err));
});
```
Listen for the device disconnection state so that the user can stop cross-device continuation or collaboration in time. The sample code is as follows:
```ts
// The token parameter is the token obtained during the registration.
continuationManager.on("deviceDisconnect", token, (deviceIds) => {
console.info('onDeviceDisconnect len: ' + deviceIds.length);
if (deviceIds.length <= 0) {
console.info('no unselected device');
return;
}
// Update the device connection state.
let unselectedDeviceId: string = deviceIds[0]; // Assign the deviceId of the first deselected remote device to the unselectedDeviceId variable.
let deviceConnectStatus: continuationManager.DeviceConnectState = continuationManager.DeviceConnectState.DISCONNECTING; // Device disconnected.
// The token parameter is the token obtained during the registration, and the unselectedDeviceId parameter is the unselectedDeviceId obtained.
continuationManager.updateConnectStatus(token, unselectedDeviceId, deviceConnectStatus).then((data) => {
console.info('updateConnectStatus finished, ' + JSON.stringify(data));
}).catch((err) => {
console.error('updateConnectStatus failed, cause: ' + JSON.stringify(err));
});
});
```
5. Start the device selection module to show the list of available devices on the network.
The sample code is as follows:
```ts
// Filter parameters.
let continuationExtraParams = {
deviceType: ["00E"], // Device type.
continuationMode: continuationManager.ContinuationMode.COLLABORATION_SINGLE // Single-choice mode of the device selection module.
};
// The token parameter is the token obtained during the registration.
continuationManager.startDeviceManager(token, continuationExtraParams).then((data) => {
console.info('startDeviceManager finished, ' + JSON.stringify(data));
}).catch((err) => {
console.error('startDeviceManager failed, cause: ' + JSON.stringify(err));
});
```
6. If you do not need to perform cross-device migration or collaboration operations, you can deregister the continuation management service, by passing the token obtained during the registration.
The sample code is as follows:
```ts
// The token parameter is the token obtained during the registration.
continuationManager.unregister(token).then((data) => {
console.info('unregister finished, ' + JSON.stringify(data));
}).catch((err) => {
console.error('unregister failed, cause: ' + JSON.stringify(err));
});

## Widget Overview
A widget is a set of UI components used to display important information or operations for an application. It provides users with direct access to a desired application service, without requiring them to open the application.
A widget displays brief information about an application on the UI of another application (host application, currently system applications only) and provides basic interactive functions such as opening a UI page or sending a message.

You can set router and message events for components on a widget. The router event applies to ability redirection, and the message event applies to custom click events. The key steps are as follows:
1. Set **onclick** in the HML file to **routerEvent** or **messageEvent**, depending on the **actions** settings in the JSON file.
2. For the router event, set the following attributes:
- **action**: **"router"**.
- **abilityName**: target ability name, for example, **com.example.entry.MainAbility**, which is the default main ability name in DevEco Studio for the FA model.
- **params**: custom parameters of the target ability. Set them as required. The value can be obtained from **parameters** in **want** used for starting the target ability. For example, in the lifecycle function **onCreate** of the main ability in the FA model, **featureAbility.getWant()** can be used to obtain **want** and its **parameters** field.

A widget is a set of UI components used to display important information or operations for an application. It provides users with direct access to a desired application service, without requiring them to open the application.
A widget displays brief information about an application on the UI of another application (host application, currently system applications only) and provides basic interactive functions such as opening a UI page or sending a message.

### Developing Widget Events
You can set router and message events for components on a widget. The router event applies to ability redirection, and the message event applies to custom click events. The key steps are as follows:
1. Set **onclick** in the HML file to **routerEvent** or **messageEvent**, depending on the **actions** settings in the JSON file.
2. For the router event, set the following attributes:
- **action**: **"router"**.
- **abilityName**: target ability name, for example, **MainAbility**, which is the default main ability name in DevEco Studio for the stage model.
- **params**: custom parameters of the target ability. Set them as required. The value can be obtained from **parameters** in **want** used for starting the target ability. For example, in the lifecycle function **onCreate** of the main ability in the stage model, you can obtain **want** and its **parameters** field.
3. For the message event, set the following attributes:
- **action**: **"message"**.
- **params**: custom parameters of the message event. Set them as required. The value can be obtained from **message** in the widget lifecycle function **onEvent**.
The following is an example:
- In the HML file:
```html
<div class="container">
<stack>
<div class="container-img">
<image src="/common/widget.png" class="bg-img"></image>
</div>
<div class="container-inner">

<text class="detail_text" onclick="messageEvent">{{detail}}</text>

# Service Extension Ability Development
## When to Use
**ExtensionAbility** is the base class of the new Extension component in the stage model. It is used to process missions without UIs. The lifecycle of an Extension ability is simple and does not involve foreground or background states. **ServiceExtensionAbility** is extended from **ExtensionAbility**.
`ExtensionAbility` is the base class of the new Extension component in the stage model. It is used to process missions without UIs. The lifecycle of an Extension ability is simple and does not involve foreground or background states. `ServiceExtensionAbility` is extended from `ExtensionAbility`.
You can customize a class that inherits from **ServiceExtensionAbility** and override the lifecycle callbacks in the base class to perform service logic operations during the initialization, connection, and disconnection processes.

# Distributed Camera Development
## When to Use
You can call the APIs provided by the **Camera** module to develop a distributed camera that provides the basic camera functions such as shooting and video recording.
## How to Develop
Connect your calculator to a distributed device. Your calculator will call **getCameras()** to obtain the camera list and traverse the returned camera list to check **ConnctionType** of the **Camera** objects. If **ConnctionType** of a **Camera** object is **CAMERA_CONNECTION_REMOTE**, your calculator will use this object to create a **CameraInput** object. The subsequent call process is the same as that of the local camera development. For details about the local camera development, see [Camera Development](./camera.md).
For details about the APIs, see [Camera Management](../reference/apis/js-apis-camera.md).
### Connecting to a Distributed Camera
Connect the calculator and the distributed device to the same LAN.
Open the calculator and click the arrow icon in the upper right corner. A new window is displayed. Enter the verification code as prompted, and the calculator will be connected to the distributed device.
### Creating an Instance
```js
import camera from '@ohos.multimedia.camera'
import image from '@ohos.multimedia.image'
import media from '@ohos.multimedia.media'
import featureAbility from '@ohos.ability.featureAbility'
// Create a CameraManager object.
let cameraManager
await camera.getCameraManager(globalThis.Context, (err, manager) => {
if (err) {
console.error('Failed to get the CameraManager instance ${err.message}');
return;
}
console.log('Callback returned with the CameraManager instance');
cameraManager = manager
})
// Register a callback to listen for camera status changes and obtain the updated camera status information.
cameraManager.on('cameraStatus', (cameraStatusInfo) => {
console.log('camera : ' + cameraStatusInfo.camera.cameraId);
console.log('status: ' + cameraStatusInfo.status);
})
// Obtain the camera list.
let cameraArray
let remoteCamera
await cameraManager.getCameras((err, cameras) => {
if (err) {
console.error('Failed to get the cameras. ${err.message}');
return;
}
console.log('Callback returned with an array of supported cameras: ' + cameras.length);
cameraArray = cameras
})
for(let cameraIndex = 0; cameraIndex < cameraArray.length; cameraIndex) {
console.log('cameraId : ' + cameraArray[cameraIndex].cameraId) // Obtain the camera ID.
console.log('cameraPosition : ' + cameraArray[cameraIndex].cameraPosition) // Obtain the camera position.
console.log('cameraType : ' + cameraArray[cameraIndex].cameraType) // Obtain the camera type.
console.log('connectionType : ' + cameraArray[cameraIndex].connectionType) // Obtain the camera connection type.
if (cameraArray[cameraIndex].connectionType == CAMERA_CONNECTION_REMOTE) {
remoteCamera = cameraArray[cameraIndex].cameraId
}
}
// Create a camera input stream.
let cameraInput
await cameraManager.createCameraInput(remoteCamera).then((input) => {
console.log('Promise returned with the CameraInput instance');
cameraInput = input
})
```
