# @ohos.app.ability.InsightIntentContext (InsightIntent Call Execution Context)

The **InsightIntentContext** module provides the InsightIntent call execution context, which is a property of the base class for InsightIntent call execution and provides basic capabilities for the base class.

> **NOTE**
>
> The initial APIs of this module are supported since API version 11. Newly added APIs will be marked with a superscript to indicate their earliest API version.
>
> The APIs of this module can be used only in the stage model.

## Modules to Import

```ts
import { InsightIntentContext } from '@kit.AbilityKit';
```

## InsightIntentContext.startAbility

startAbility(want: Want, callback: AsyncCallback\<void\>): void

Starts an ability. The ability can be started only when it has the same bundle name as the base class for InsightIntent call execution. This API uses an asynchronous callback to return the result.

**Model restriction**: This API can be used only in the stage model.

**Atomic service API**: This API can be used in atomic services since API version 11.

**System capability**: SystemCapability.Ability.AbilityRuntime.Core

**Parameters**

| Name| Type| Mandatory| Description|
| -------- | -------- | -------- | -------- |
| want | [Want](js-apis-app-ability-want.md) | Yes| Want information about the target ability.|
| callback | AsyncCallback&lt;void&gt; | Yes| Callback used to return the result. If the ability is started, **err** is **undefined**. Otherwise, **err** is an error object.|

**Example**

  ```ts
  import { InsightIntentExecutor, insightIntent, Want } from '@kit.AbilityKit';

      let want: Want = {
        bundleName: 'com.ohos.intentexecutedemo',
        moduleName: 'entry',
        abilityName: 'AnotherAbility',
      };

      try {
        this.context.startAbility(want, (error) => {
          if (error) {

  }
  ```

## InsightIntentContext.startAbility

startAbility(want: Want): Promise\<void\>

Starts an ability. The ability can be started only when it has the same bundle name as the base class for InsightIntent call execution. This API uses a promise to return the result.

**Model restriction**: This API can be used only in the stage model.

**Atomic service API**: This API can be used in atomic services since API version 11.

**System capability**: SystemCapability.Ability.AbilityRuntime.Core

**Parameters**

| Name| Type| Mandatory| Description|
| -------- | -------- | -------- | -------- |
| want | [Want](js-apis-app-ability-want.md) | Yes| Want information about the target ability.|

**Return value**

| Type| Description|
| -------- | -------- |
| Promise&lt;void&gt; | Promise that returns no value.|
