Requesting Permissions

If an application needs to obtain user privacy information or use system capabilities, for example, obtaining location information or using the camera to take photos or record videos, it must request the respective permission from users.

During application development, you must declare the required permission in the config.json file and call requestPermissionsFromUser to request the permission from users in the form of a dialog box.

To declare a permission in config.json, add reqPermissions under module and list the permission.

For example, to request the permission to access the calendar, perform the following steps:

1. Request the ohos.permission.DISTRIBUTED_DATASYNC permission. For details, see Declaring Permissions in the Configuration File.
2. Display a dialog box to ask authorization from the user when the application is started for the first time. For details, see Requesting User Authorization.
