RouteDiscoveryPreference

Kotlin |Java

class RouteDiscoveryPreference : Parcelable

kotlin.Any
↳	android.media.RouteDiscoveryPreference

A media route discovery preference describing the features of routes that media router would like to discover and whether to perform active scanning.

When MediaRouter2 instances set discovery preferences by calling MediaRouter2#registerRouteCallback, they are merged into a single discovery preference and it is delivered to call MediaRoute2ProviderService#onDiscoveryPreferenceChanged.

According to the given discovery preference, MediaRoute2ProviderService discovers routes and publishes them.

Summary

Nested classes
	`Builder` Builder for `RouteDiscoveryPreference`.

Inherited constants

From class Parcelable

Int

CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

Int

PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Public methods
Int	`describeContents()`
Boolean	`equals(other: Any?)`
MutableList<String!>	`getPreferredFeatures()` Gets the features of routes that media router would like to discover.
Int	`hashCode()`
Boolean	`shouldPerformActiveScan()` Gets whether active scanning should be performed.
String	`toString()`
Unit	`writeToParcel(dest: Parcel, flags: Int)` Flatten this object in to a Parcel.

Public methods

describeContents

Added in API level 30

fun describeContents(): Int

Return
`Int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR`

equals

Added in API level 30

fun equals(other: Any?): Boolean

Parameters
`obj`	the reference object with which to compare.

Return
`Boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

getPreferredFeatures

Added in API level 30

fun getPreferredFeatures(): MutableList<String!>

Gets the features of routes that media router would like to discover.

Routes that have at least one of the features will be discovered. They may include predefined features such as MediaRoute2Info#FEATURE_LIVE_AUDIO, MediaRoute2Info#FEATURE_LIVE_VIDEO, or MediaRoute2Info#FEATURE_REMOTE_PLAYBACK or custom features defined by a provider.

Return
`MutableList<String!>`	This value cannot be `null`.

hashCode

Added in API level 30

fun hashCode(): Int

Return
`Int`	a hash code value for this object.

shouldPerformActiveScan

Added in API level 30

fun shouldPerformActiveScan(): Boolean

Gets whether active scanning should be performed.

If any of discovery preferences sets this as true, active scanning will be performed regardless of other discovery preferences.

toString

Added in API level 30

fun toString(): String

Return
`String`	a string representation of the object.

writeToParcel

Added in API level 30

fun writeToParcel(
    dest: Parcel, 
    flags: Int
): Unit

Flatten this object in to a Parcel.

Parameters
`dest`	Parcel: This value cannot be `null`.
`flags`	Int: Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES

Properties

CREATOR

Added in API level 30

static val CREATOR: Parcelable.Creator<RouteDiscoveryPreference!>
