Metadata

The Metadata module defines a metadata object. An application can obtain the metadata through bundleManager.getBundleInfoForSelf, with GET_BUNDLE_INFO_WITH_METADATA passed in for bundleFlags. This object is contained in ApplicationInfo, HapModuleInfo, AbilityInfo, and ExtensionAbilityInfo.

The Metadata module provides the configuration about the module, UIAbility, and ExtensionAbility. The value is of the array type. The configuration is valid only for the current module, UIAbility, or ExtensionAbility.

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.
