# android.support.v17.leanback.app added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) # android.support.v17.leanback.app | This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings). Support classes providing high level Leanback user interface building blocks. Leanback fragments are available both as support fragments (subclassed from[android.support.v4.app.Fragment](https://developer.android.com/reference/android/support/v4/app/Fragment)) and as platform fragments (subclassed from[android.app.Fragment](https://developer.android.com/reference/android/app/Fragment.html)). A few of the most commonly used leanback fragments are described here. A[BrowseSupportFragment](https://developer.android.com/reference/android/support/v17/leanback/app/BrowseSupportFragment)by default operates in the "row" mode. It includes an optional "fastlane" navigation side panel and a list of rows, with one-to-one correspondance between each header in the fastlane and a row. The application supplies the[ObjectAdapter](https://developer.android.com/reference/android/support/v17/leanback/widget/ObjectAdapter)containing the list of rows and a[PresenterSelector](https://developer.android.com/reference/android/support/v17/leanback/widget/PresenterSelector)of row presenters. A[BrowseSupportFragment](https://developer.android.com/reference/android/support/v17/leanback/app/BrowseSupportFragment)also works in a "page" mode when each row of fastlane is mapped to a fragment that the app registers in[getMainFragmentRegistry()](https://developer.android.com/reference/android/support/v17/leanback/app/BrowseSupportFragment#getMainFragmentRegistry()). A[DetailsSupportFragment](https://developer.android.com/reference/android/support/v17/leanback/app/DetailsSupportFragment)will typically consist of a large overview of an item at the top, some actions that a user can perform, and possibly rows of additional or related items. The content for this fragment is specified in the same way as for the BrowseSupportFragment, with the convention that the first element in the ObjectAdapter corresponds to the overview row. The[DetailsOverviewRow](https://developer.android.com/reference/android/support/v17/leanback/widget/DetailsOverviewRow)and[FullWidthDetailsOverviewRowPresenter](https://developer.android.com/reference/android/support/v17/leanback/widget/FullWidthDetailsOverviewRowPresenter)provide a default template for this row. A[PlaybackSupportFragment](https://developer.android.com/reference/android/support/v17/leanback/app/PlaybackSupportFragment)or its subclass[VideoSupportFragment](https://developer.android.com/reference/android/support/v17/leanback/app/VideoSupportFragment)hosts[PlaybackTransportControlGlue](https://developer.android.com/reference/android/support/v17/leanback/media/PlaybackTransportControlGlue)or[PlaybackBannerControlGlue](https://developer.android.com/reference/android/support/v17/leanback/media/PlaybackBannerControlGlue)with a Leanback look and feel. It is recommended to use an instance of[PlaybackTransportControlGlue](https://developer.android.com/reference/android/support/v17/leanback/media/PlaybackTransportControlGlue). This helper implements a standard behavior for user interaction with the most commonly used controls as well as video scrubbing. A[SearchSupportFragment](https://developer.android.com/reference/android/support/v17/leanback/app/SearchSupportFragment)allows the developer to accept a query from a user and display the results using the familiar list rows. A[GuidedStepSupportFragment](https://developer.android.com/reference/android/support/v17/leanback/app/GuidedStepSupportFragment)is used to guide the user through a decision or series of decisions. ##
