MediaRouteDiscoveryFragment

Kotlin |Java

open class MediaRouteDiscoveryFragment : Fragment

kotlin.Any
↳	androidx.fragment.app.Fragment
	↳	androidx.mediarouter.app.MediaRouteDiscoveryFragment

Media route discovery fragment.

This fragment takes care of registering a callback with proper flags for media route discovery:

In Fragment#onCreate phase, the callback is registered with zero flags.
In Fragment#onStart phase, the callback's flags are set to the value which is provided by onPrepareCallbackFlags().
In Fragment#onStop() phase, the callback's flags are set to zero.

The application must supply a route selector to specify the kinds of routes to discover. The application may also override onCreateCallback to provide the MediaRouter callback to register.

Note that the discovery callback makes the application be connected with all the media route provider services while it is registered.

Inherited functions

From class Fragment

`Unit`	`dump(@NonNull prefix: String, @Nullable fd: FileDescriptor?, @NonNull writer: PrintWriter, @Nullable args: Array<String!>?)` Print the Fragments's state into the given stream.
`Boolean`	`equals(@Nullable other: Any?)` Subclasses can not override equals().
`FragmentActivity?`	`getActivity()` Return the `FragmentActivity` this fragment is currently associated with. May return `null` if the fragment is associated with a `Context` instead.
`Boolean`	`getAllowEnterTransitionOverlap()` Returns whether the the exit transition and enter transition overlap or not. When true, the enter transition will start as soon as possible. When false, the enter transition will wait until the exit transition completes before starting.
`Boolean`	`getAllowReturnTransitionOverlap()` Returns whether the the return transition and reenter transition overlap or not. When true, the reenter transition will start as soon as possible. When false, the reenter transition will wait until the return transition completes before starting.
`Bundle?`	`getArguments()` Return the arguments supplied when the fragment was instantiated, if any.
`FragmentManager`	`getChildFragmentManager()` Return a private FragmentManager for placing and managing Fragments inside of this Fragment.
`Context?`	`getContext()` Return the `Context` this fragment is currently associated with.
`ViewModelProvider.Factory`	`getDefaultViewModelProviderFactory()` Returns the default `ViewModelProvider.Factory` that should be used when no custom `Factory` is provided to the `ViewModelProvider` constructors. The `Fragment's arguments` when this is first called will be used as the defaults to any `androidx.lifecycle.SavedStateHandle` passed to a view model created using this factory.
`Any?`	`getEnterTransition()` Returns the Transition that will be used to move Views into the initial scene. The entering Views will be those that are regular Views or ViewGroups that have `ViewGroup#isTransitionGroup` return true. Typical Transitions will extend `android.transition.Visibility` as entering is governed by changing visibility from `View#INVISIBLE` to `View#VISIBLE`.
`Any?`	`getExitTransition()` Returns the Transition that will be used to move Views out of the scene when the fragment is removed, hidden, or detached when not popping the back stack. The exiting Views will be those that are regular Views or ViewGroups that have `ViewGroup#isTransitionGroup` return true. Typical Transitions will extend `android.transition.Visibility` as exiting is governed by changing visibility from `View#VISIBLE` to `View#INVISIBLE`. If transition is null, the views will remain unaffected.
