An app can call CameraPicker to take photos or record videos without requesting camera permissions.

The camera interaction UI of the camera picker is provided by the system. After a user taps the capture and confirm buttons, the application that invokes the camera picker obtains a photo or video.

If your application only needs to obtain photos or videos taken in real time, it can invoke the camera picker.

Given that users are the ones who actively take and confirm the photos, your application does not need to request the permission to operate the camera.

How to Develop

For detailed API descriptions, see @ohos.multimedia.cameraPicker (Camera Picker).

Import the modules.

import { camera, cameraPicker as picker } from '@kit.CameraKit';
import { fileIo, fileUri } from '@kit.CoreFileKit';

Index.ets

Configure PickerProfile.

NOTE

The saveUri parameter of PickerProfile is optional. If this parameter is not set, photos and videos are stored in the media library by default.

If you do not want to save photos and videos to the media library, configure a file path in the application sandbox. Ensure that this file is already present and writable. By passing the file's URI into the picker API, you are effectively giving the camera picker permission to read from and write to this file. Upon completion of a photo or video capture, the camera picker will replace the contents of this file.
```
createPickerProfile(context: Context): picker.PickerProfile {
  let pathDir = context.filesDir;
  let fileName = `${new Date().getTime()}`;
  let filePath = pathDir + `/${fileName}.tmp`;
  fileIo.createRandomAccessFileSync(filePath, fileIo.OpenMode.CREATE);
  
  let uri = fileUri.getUriFromPath(filePath);
  let pickerProfile: picker.PickerProfile = {
    cameraPosition: camera.CameraPosition.CAMERA_POSITION_BACK,
    saveUri: uri
  };
  return pickerProfile;
}
```
Index.ets

For the fileIo API calling methods, see createRandomAccessFileSync and getUriFromPath.

Call the picker API to obtain the photo or video capture result.

async getPickerResult(context: Context, pickerProfile: picker.PickerProfile): Promise<picker.PickerResult> {
  let result: picker.PickerResult =
    await picker.pick(context, [picker.PickerMediaType.PHOTO, picker.PickerMediaType.VIDEO],
      pickerProfile);
  console.info(`picker resultCode: ${result.resultCode},resultUri: ${result.resultUri},mediaType: ${result.mediaType}`);
  return result;
}
