use[BrowseSupportFragment](https://developer.android.com/reference/android/support/v17/leanback/app/BrowseSupportFragment)

Registry class maintaining the mapping of[Row](https://developer.android.com/reference/android/support/v17/leanback/widget/Row)subclasses to[BrowseFragment.FragmentFactory](https://developer.android.com/reference/android/support/v17/leanback/app/BrowseFragment.FragmentFactory). BrowseRowFragment automatically registers[BrowseFragment.ListRowFragmentFactory](https://developer.android.com/reference/android/support/v17/leanback/app/BrowseFragment.ListRowFragmentFactory)for handling[ListRow](https://developer.android.com/reference/android/support/v17/leanback/widget/ListRow). Developers can override that and also if they want to use custom fragment, they can register a custom[BrowseFragment.FragmentFactory](https://developer.android.com/reference/android/support/v17/leanback/app/BrowseFragment.FragmentFactory)against[PageRow](https://developer.android.com/reference/android/support/v17/leanback/widget/PageRow).
