The support library has been superseded by [AndroidX](/jetpack/androidx) which is part of [Jetpack](/jetpack).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\nIdlingResource.ResourceCallback\n`\n\n\n`\n\n\n`\n\n|---------------------------------------------------------------|\n| android.support.test.espresso.IdlingResource.ResourceCallback |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\nRegistered by an [IdlingResource](/reference/android/support/test/espresso/IdlingResource) to notify Espresso of a transition to idle.\n\nSummary\n-------\n\n| ### Public methods ||\n|------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| ` abstract void` | ` `[onTransitionToIdle](/reference/android/support/test/espresso/IdlingResource.ResourceCallback#onTransitionToIdle())`() ` Called when the resource goes from busy to idle. |\n\nPublic methods\n--------------\n\n### onTransitionToIdle\n\n```\nvoid onTransitionToIdle ()\n```\n\nCalled when the resource goes from busy to idle.\n\n\u003cbr /\u003e\n\n-\n\n Interfaces\n ----------\n\n - [EspressoException](/reference/android/support/test/espresso/EspressoException)\n - [FailureHandler](/reference/android/support/test/espresso/FailureHandler)\n - [IdlingResource](/reference/android/support/test/espresso/IdlingResource)\n - [IdlingResource.ResourceCallback](/reference/android/support/test/espresso/IdlingResource.ResourceCallback)\n - [UiController](/reference/android/support/test/espresso/UiController)\n - [ViewAction](/reference/android/support/test/espresso/ViewAction)\n - [ViewAssertion](/reference/android/support/test/espresso/ViewAssertion)\n - [ViewFinder](/reference/android/support/test/espresso/ViewFinder)\n - [ViewInteractionComponent](/reference/android/support/test/espresso/ViewInteractionComponent)\n-\n\n Classes\n -------\n\n - [AmbiguousViewMatcherException.Builder](/reference/android/support/test/espresso/AmbiguousViewMatcherException.Builder)\n - [DataInteraction](/reference/android/support/test/espresso/DataInteraction)\n - [DataInteraction.DisplayDataMatcher](/reference/android/support/test/espresso/DataInteraction.DisplayDataMatcher)\n - [Espresso](/reference/android/support/test/espresso/Espresso)\n - [IdlingPolicies](/reference/android/support/test/espresso/IdlingPolicies)\n - [IdlingPolicy](/reference/android/support/test/espresso/IdlingPolicy)\n - [IdlingRegistry](/reference/android/support/test/espresso/IdlingRegistry)\n - [NoMatchingViewException.Builder](/reference/android/support/test/espresso/NoMatchingViewException.Builder)\n - [PerformException.Builder](/reference/android/support/test/espresso/PerformException.Builder)\n - [Root](/reference/android/support/test/espresso/Root)\n - [Root.Builder](/reference/android/support/test/espresso/Root.Builder)\n - [ViewInteraction](/reference/android/support/test/espresso/ViewInteraction)\n-\n\n Exceptions\n ----------\n\n - [AmbiguousViewMatcherException](/reference/android/support/test/espresso/AmbiguousViewMatcherException)\n - [AppNotIdleException](/reference/android/support/test/espresso/AppNotIdleException)\n - [IdlingResourceTimeoutException](/reference/android/support/test/espresso/IdlingResourceTimeoutException)\n - [InjectEventSecurityException](/reference/android/support/test/espresso/InjectEventSecurityException)\n - [NoActivityResumedException](/reference/android/support/test/espresso/NoActivityResumedException)\n - [NoMatchingRootException](/reference/android/support/test/espresso/NoMatchingRootException)\n - [NoMatchingViewException](/reference/android/support/test/espresso/NoMatchingViewException)\n - [PerformException](/reference/android/support/test/espresso/PerformException)"]]
