## How to Develop
The procedure for developing the ability call is as follows:
1. Create a callee ability.
2. Access the callee ability.
### Creating a Callee Ability
For the callee ability, implement the callback to receive data and the methods to marshal and unmarshal data. When data needs to be received, use **on()** to register a listener. When data does not need to be received, use **off()** to deregister the listener.
**1. Configure the ability launch type.**
1. **Configure the ability launch type.**
Set **launchType** of the callee ability to **singleton** in the **module.json5** file.

"launchType": "singleton",
"description": "$string:CalleeAbility_desc",
"icon": "$media:icon",
"label": "$string:CalleeAbility_label",

**2. Import the Ability module.**

"exported": true
}]
```
2. **Import the UIAbility module.**
```ts
import UIAbility from '@ohos.app.ability.UIAbility';
```
3. **Define the agreed sequenceable data.**
The data formats sent and received by the caller and callee abilities must be consistent. In the following example, the data formats are number and string. The code snippet is as follows:
```ts
export default class MySequenceable {
```ts

```
4. **Implement Callee.on and Callee.off.**
The time to register a listener for the callee ability depends on your application. The data sent and received before the listener is registered and that after the listener is deregistered are not processed. In the following example, the **MSG_SEND_METHOD** listener is registered in **onCreate** of the ability and deregistered in **onDestroy**. After receiving sequenceable data, the application processes the data and returns the data result. You need to implement processing based on service requirements. The code snippet is as follows:
```ts
const TAG: string = '[CalleeAbility]'
const MSG_SEND_METHOD: string = 'CallSendMsg'
function sendMsgCallback(data) {

The following example uses **this.context** to obtain the **context** attribute of the ability, uses **startAbilityByCall** to start the callee ability, obtain the **Caller** object, and register the **onRelease** listener of the caller ability. You need to implement processing based on service requirements. The code snippet is as follows:
```ts
// Register the onRelease listener of the caller ability.
private regOnRelease(caller) {

The sequenceable data can be sent to the callee ability with or without a return value. The method and sequenceable data must be consistent with those of the callee ability. The following example describes how to send data to the callee ability. The code snippet is as follows:

- **abilityName**: target ability name, for example, **EntryAbility**, 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 EntryAbility in the stage model, you can obtain **want** and its **parameters** field.
3. Set the message event.

### Tools
## Tools
DevEco Studio is a high-performance integrated development environment (IDE) recommended for developing OpenHarmony applications.
[Here](https://developer.harmonyos.com/en/docs/documentation/doc-guides/ohos-deveco-studio-overview-0000001263280421) you can learn everything about DevEco Studio, including how to use this tool to create a project and sign, debug, and run an application.
### Hands-On Tutorials
## Hands-On Tutorials
To make you better understand how functions work together and jumpstart your application development projects, we provide stripped-down, real-world [samples](https://gitee.com/openharmony/applications_app_samples/blob/master/README.md) and [codelabs](https://gitee.com/openharmony/codelabs).
### API References

# @ohos.arkui.drawableDescriptor (DrawableDescriptor)
The **DrawableDescriptor** module provides APIs for obtaining **pixelMap** objects, including the foreground, background, mask, and layered icons.
> **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.
>
> You can preview how this component looks on a real device. The preview is not yet available in the DevEco Studio Previewer.
## Modules to Import
```js
import { DrawableDescriptor, LayeredDrawableDescriptor } from '@ohos.arkui.drawableDescriptor';
```
## DrawableDescriptor.constructor
constructor()
Creates a **DrawableDescriptor** or **LayeredDrawableDescriptor** object. The globalization API [getDrawableDescriptor](js-apis-resource-manager.md##getdrawabledescriptor) or [getDrawableDescriptorByName](js-apis-resource-manager.md##getdrawabledescriptorbyname) is required for object construction.
**System API**: This is a system API.
**System capability**: SystemCapability.ArkUI.ArkUI.Full
### DrawableDescriptor
Creates a **DrawableDescriptor** object when the passed resource ID or name belongs to a common image.
### LayeredDrawableDescriptor
Creates a **LayeredDrawableDescriptor** object when the passed resource ID or name belongs to a JSON file that contains foreground and background resources.
**Example**
```js
@Entry
@Component
struct Index {
private resManager = getContext().resourceManager
let drawable1 = resManager.getDrawableDescriptor($r('app.media.icon').id)
let drawable2 = resManager.getDrawableDescriptorByName(icon)
let layeredDrawable1 = resManager.getDrawableDescriptor($r('app.media.file').id)
let layeredDrawable1 = resManager.getDrawableDescriptor(file)
}
```
## DrawableDescriptor.getPixelMap
getPixelMap(): image.PixelMap;
Obtains this **pixelMap** object.
**System capability**: SystemCapability.ArkUI.ArkUI.Full

# @ohos.inputMethod (Input Method Framework)
The **inputMethod** module provides an input method framework, which can be used to hide the keyboard, obtain the list of installed input methods, display the dialog box for input method selection, and more.
The **inputMethod** module is oriented to common foreground applications (third-party applications and system applications such as Notes, Messaging, and Settings). It provides input method control and management capabilities, including displaying or hiding the soft keyboard, switching between input methods, and obtaining the list of all input methods.
