@ohos.multimedia.cameraPicker (Camera Picker)

The cameraPicker module provides APIs for an application to use the system camera to take photos or record videos, depending on the media type specified by the application. The application must call these APIs within a UIAbility. Otherwise, the camera picker cannot be started.

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.

cameraPicker.pick

pick(context: Context, mediaTypes: Array<PickerMediaType>, pickerProfile: PickerProfile): Promise<PickerResult>

Starts the camera picker and enters the corresponding mode based on the media type. This API uses a promise to return the result.
