Media route discovery fragment.

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

- In `https://developer.android.com/reference/androidx/fragment/app/Fragment#onCreate(android.os.Bundle)` phase, the callback is registered with zero flags.
- In `https://developer.android.com/reference/androidx/fragment/app/Fragment#onStart()` phase, the callback's flags are set to the value which is provided by `https://developer.android.com/reference/androidx/mediarouter/app/MediaRouteDiscoveryFragment#onPrepareCallbackFlags()`.
- In `https://developer.android.com/reference/androidx/fragment/app/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 `https://developer.android.com/reference/androidx/mediarouter/app/MediaRouteDiscoveryFragment#onCreateCallback()` to provide the `https://developer.android.com/reference/androidx/mediarouter/media/MediaRouter` callback to register.

Note that the discovery callback makes the application be connected with all the `https://developer.android.com/reference/androidx/mediarouter/media/MediaRouteProviderService` while it is registered.

## Public constructors

### MediaRouteDiscoveryFragment

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/mediarouter#1.1.0)

```
public MediaRouteDiscoveryFragment()
```

## Public methods

### getMediaRouter

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/mediarouter#1.1.0)

```
public @NonNull MediaRouter getMediaRouter()
```

Gets the media router instance.

### getRouteSelector

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/mediarouter#1.1.0)

```
public @NonNull MediaRouteSelector getRouteSelector()
```

Gets the media route selector for filtering the routes to be discovered.

| Returns |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/androidx/mediarouter/media/MediaRouteSelector` | The selector, never null. |

### onCreate

```
public void onCreate(@Nullable Bundle savedInstanceState)
```

Called to do initial creation of a fragment. This is called after `https://developer.android.com/reference/androidx/fragment/app/Fragment#onAttach(android.app.Activity)` and before `https://developer.android.com/reference/androidx/fragment/app/Fragment#onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)`.

Note that this can be called while the fragment's activity is still in the process of being created. As such, you can not rely on things like the activity's content view hierarchy being initialized at this point. If you want to do work once the activity itself is created, add a `https://developer.android.com/reference/androidx/lifecycle/LifecycleObserver` on the activity's Lifecycle, removing it when it receives the `https://developer.android.com/reference/androidx/lifecycle/Lifecycle.State#CREATED` callback.

Any restored child fragments will be created before the base `Fragment.onCreate` method returns.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/Nullable.html https://developer.android.com/reference/android/os/Bundle.html savedInstanceState` | If the fragment is being re-created from a previous saved state, this is the state. |

### onCreateCallback

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/mediarouter#1.1.0)

```
public @Nullable MediaRouter.Callback onCreateCallback()
```

Called to create the `https://developer.android.com/reference/androidx/mediarouter/media/MediaRouter.Callback` that will be registered.

The default callback does nothing. The application may override this method to supply its own callback.

| Returns |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/Nullable.html https://developer.android.com/reference/androidx/mediarouter/media/MediaRouter.Callback` | The new callback, or null if no callback should be registered. |

### onDestroy

```
public void onDestroy()
```

Called when the fragment is no longer in use. This is called after `https://developer.android.com/reference/androidx/fragment/app/Fragment#onStop()` and before `https://developer.android.com/reference/androidx/fragment/app/Fragment#onDetach()`.

### onPrepareCallbackFlags

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/mediarouter#1.1.0)

```
public int onPrepareCallbackFlags()
```

Called to prepare the callback flags that will be used when the `https://developer.android.com/reference/androidx/mediarouter/media/MediaRouter.Callback` is registered.

The default implementation returns `https://developer.android.com/reference/androidx/mediarouter/media/MediaRouter#CALLBACK_FLAG_REQUEST_DISCOVERY()`.

| Returns |
|---|---|
| `int` | The desired callback flags. |

### onStart

```
public void onStart()
```

Called when the Fragment is visible to the user. This is generally tied to `https://developer.android.com/reference/android/app/Activity.html#onStart()` of the containing Activity's lifecycle.

### onStop

```
public void onStop()
```

Called when the Fragment is no longer started. This is generally tied to `https://developer.android.com/reference/android/app/Activity.html#onStop()` of the containing Activity's lifecycle.

### setRouteSelector

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/mediarouter#1.1.0)

```
public void setRouteSelector(@NonNull MediaRouteSelector selector)
```

Sets the media route selector for filtering the routes to be discovered. This method must be called before the fragment is added.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/androidx/mediarouter/media/MediaRouteSelector selector` | The selector to set. |
