Requesting User Authorization for the Second Time

If the user rejects to grant the permission when an application calls requestPermissionsFromUser() to request user authorization in a dialog box, the application will no longer start the user authorization dialog box again by using requestPermissionsFromUser(). If the application still needs the permission, you can use either of the following methods:

• Allow the user to manually grant the permission using the system application Settings in the following path:

Privacy > Permission manager > Permission type (such as Location) > App

• Start the permission settings dialog box by using requestPermissionOnSetting() and guide the user to grant the permission.

Figure 1 Requesting user authorization for the second time

The following code shows how to request the ohos.permission.APPROXIMATELY_LOCATION permission in this way.

import { abilityAccessCtrl, Context, common } from '@kit.AbilityKit';
import { BusinessError } from '@kit.BasicServicesKit';

let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
let context: Context = getContext(this) as common.UIAbilityContext;
atManager.requestPermissionOnSetting(context, ['ohos.permission.APPROXIMATELY_LOCATION']).then((data: Array<abilityAccessCtrl.GrantStatus>) => {
  console.info('data:' + JSON.stringify(data));
}).catch((err: BusinessError) => {
  console.error('data:' + JSON.stringify(err));
});
