@ohos.app.form.formProvider (formProvider)

The FormProvider module provides APIs related to the widget provider. You can use the APIs to update a widget, set the next refresh time for a widget, obtain widget information, and request a widget release.

NOTE

The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.

Modules to Import

import { formProvider } from '@kit.FormKit';

formProvider.setFormNextRefreshTime

setFormNextRefreshTime(formId: string, minute: number, callback: AsyncCallback<void>): void

Sets the next refresh time for a widget. This API uses an asynchronous callback to return the result.

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

System capability: SystemCapability.Ability.Form

Parameters

Name Type Mandatory Description
formId string Yes Widget ID.
minute number Yes Time after which a widget is updated. The value is greater than or equal to 5, in minutes.
callback AsyncCallback<void> Yes Callback used to return the result.

Error codes

For details about the error codes, see Universal Error Codes and Form Error Codes.

Error Code ID Error Message
401 Parameter error. Possible causes: 1.Mandatory parameters are left unspecified; 2.Incorrect parameter types; 3.Parameter verification failed.
16500050 IPC connection error.
16500060 Service connection error.
16500100 Failed to obtain the configuration information.
16501000 An internal functional error occurred.
16501001 The ID of the form to be operated does not exist.
16501002 The number of forms exceeds the maximum allowed.
16501003 The form cannot be operated by the current application.

try {
  formProvider.setFormNextRefreshTime(formId, 5, (error: BusinessError) => {
    if (error) {
      console.error(`callback error, code: ${error.code}, message: ${error.message})`);
      return;
