The support library has been superseded by [AndroidX](/jetpack/androidx) which is part of [Jetpack](/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider [migrating](/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class\n| mappings](/jetpack/androidx/migrate/class-mappings).\n\n\n`\npublic\nstatic\n\n\ninterface\nCancellationSignal.OnCancelListener\n`\n\n\n`\n\n\n`\n\n|-----------------------------------------------------------|\n| android.support.v4.os.CancellationSignal.OnCancelListener |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\nListens for cancellation.\n\nSummary\n-------\n\n| ### Public methods ||\n|------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| ` abstract void` | ` `[onCancel](/reference/android/support/v4/os/CancellationSignal.OnCancelListener#onCancel())`() ` Called when [cancel()](/reference/android/support/v4/os/CancellationSignal#cancel()) is invoked. |\n\nPublic methods\n--------------\n\n### onCancel\n\nadded in [version 24.1.0](/topic/libraries/support-library/revisions) \n\n```\nvoid onCancel ()\n```\n\nCalled when [cancel()](/reference/android/support/v4/os/CancellationSignal#cancel()) is invoked.\n\n\u003cbr /\u003e\n\n-\n\n Interfaces\n ----------\n\n - [CancellationSignal.OnCancelListener](/reference/android/support/v4/os/CancellationSignal.OnCancelListener)\n - [ParcelableCompatCreatorCallbacks](/reference/android/support/v4/os/ParcelableCompatCreatorCallbacks)\n-\n\n Classes\n -------\n\n - [BuildCompat](/reference/android/support/v4/os/BuildCompat)\n - [CancellationSignal](/reference/android/support/v4/os/CancellationSignal)\n - [ConfigurationCompat](/reference/android/support/v4/os/ConfigurationCompat)\n - [EnvironmentCompat](/reference/android/support/v4/os/EnvironmentCompat)\n - [LocaleListCompat](/reference/android/support/v4/os/LocaleListCompat)\n - [ParcelableCompat](/reference/android/support/v4/os/ParcelableCompat)\n - [TraceCompat](/reference/android/support/v4/os/TraceCompat)\n - [UserManagerCompat](/reference/android/support/v4/os/UserManagerCompat)\n-\n\n Exceptions\n ----------\n\n - [OperationCanceledException](/reference/android/support/v4/os/OperationCanceledException)"]]
