Fault management is an important way for applications to deliver a better user experience. The application framework offers three methods for application fault management: fault listening, fault rectification, and fault query.
- Fault listening refers to the process of registering [ErrorObserver](../reference/apis/js-apis-application-errorManager.md#errorobserver) via [errorManager](../reference/apis/js-apis-application-errorManager.md), listening for fault occurrence, and notifying the fault listener.
- Fault listening refers to the process of registering [ErrorObserver](../reference/apis/js-apis-inner-application-errorObserver.md) via [errorManager](../reference/apis/js-apis-app-ability-errorManager.md), listening for fault occurrence, and notifying the fault listener.
- Fault rectification refers to [appRecovery](../reference/apis/js-apis-app-ability-appRecovery.md) and restarts an application to restore its status previous to a fault.

It is recommended that you call [errorManager](../reference/apis/js-apis-application-errorManager.md) to process the exception. After the processing is complete, you can call the status saving API and restart the application.

If you do not register [ErrorObserver](../reference/apis/js-apis-application-errorManager.md#errorobserver) or enable application recovery, the application process will exit according to the default processing logic of the system. Users can restart the application from the home screen.

If you have enabled application recovery, the framework first checks whether a fault allows for ability status saving and whether you have configured ability status saving. If so, [onSaveState](../reference/apis/js-apis-application-ability.md#abilityonsavestate) of [Ability](../reference/apis/js-apis-application-ability.md#ability) is called back. Finally, the application is restarted.

The **sensitivity** parameter is used to specify the levels of differences that will be used for string comparison. The value **base** indicates that only characters are compared, but not the accent and capitalization. For example, 'a' != 'b', 'a' == '', 'a'=='A'. The value **accent** indicates that the accent is considered, but not the capitalization. For example, 'a' != 'b', 'a' == '', 'a'=='A'. The value **case** indicates that the capitalization is considered, but the accent. For example, 'a' != 'b', 'a' == '', 'a'=='A'.
