The support library has been superseded by [AndroidX](/jetpack/androidx) which is part of [Jetpack](/jetpack).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\nAnnotations\n-----------\n\n|------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------|\n| [Default](/reference/android/support/test/espresso/base/Default) | Annotates a default provider. |\n| [MainThread](/reference/android/support/test/espresso/base/MainThread) | Annotates an Executor that executes tasks on the main thread |\n| [RootViewPickerScope](/reference/android/support/test/espresso/base/RootViewPickerScope) | Scope for components that use [RootViewPicker](/reference/android/support/test/espresso/base/RootViewPicker). |\n\nInterfaces\n----------\n\n|------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| [ActiveRootLister](/reference/android/support/test/espresso/base/ActiveRootLister) | Provides access to all root views in an application. |\n| [IdlingUiController](/reference/android/support/test/espresso/base/IdlingUiController) | Similar to [UiController](/reference/android/support/test/espresso/UiController) but with one additional method that enables getting an instance of [IdlingResourceRegistry](/reference/android/support/test/espresso/base/IdlingResourceRegistry). |\n| [InterruptableUiController](/reference/android/support/test/espresso/base/InterruptableUiController) | Similar to [UiController](/reference/android/support/test/espresso/UiController) but with one additional method that enables interrupting Espresso tasks. |\n\nClasses\n-------\n\n|------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------|\n| [DefaultFailureHandler](/reference/android/support/test/espresso/base/DefaultFailureHandler) | Espresso's default [FailureHandler](/reference/android/support/test/espresso/FailureHandler). |\n| [IdlingResourceRegistry](/reference/android/support/test/espresso/base/IdlingResourceRegistry) | Keeps track of user-registered [IdlingResources](/reference/android/support/test/espresso/IdlingResource). |\n| [RootViewPicker](/reference/android/support/test/espresso/base/RootViewPicker) | Provides the root View of the top-most Window, with which the user can interact. |\n| [ViewFinderImpl](/reference/android/support/test/espresso/base/ViewFinderImpl) | Implementation of [ViewFinder](/reference/android/support/test/espresso/ViewFinder). |\n\n-\n\n Annotations\n -----------\n\n - [Default](/reference/android/support/test/espresso/base/Default)\n - [MainThread](/reference/android/support/test/espresso/base/MainThread)\n - [RootViewPickerScope](/reference/android/support/test/espresso/base/RootViewPickerScope)\n-\n\n Interfaces\n ----------\n\n - [ActiveRootLister](/reference/android/support/test/espresso/base/ActiveRootLister)\n - [IdlingUiController](/reference/android/support/test/espresso/base/IdlingUiController)\n - [InterruptableUiController](/reference/android/support/test/espresso/base/InterruptableUiController)\n-\n\n Classes\n -------\n\n - [DefaultFailureHandler](/reference/android/support/test/espresso/base/DefaultFailureHandler)\n - [IdlingResourceRegistry](/reference/android/support/test/espresso/base/IdlingResourceRegistry)\n - [RootViewPicker](/reference/android/support/test/espresso/base/RootViewPicker)\n - [ViewFinderImpl](/reference/android/support/test/espresso/base/ViewFinderImpl)"]]
