Builder

open class Builder

kotlin.Any
↳	androidx.media.AudioAttributesCompat.Builder

Builder class for AudioAttributesCompat objects.

example:

new AudioAttributes.Builder()
      .setUsage(AudioAttributes.USAGE_MEDIA)
      .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
      .build();
      

By default all types of information (usage, content type, flags) conveyed by an AudioAttributesCompat instance are set to "unknown". Unknown information will be interpreted as a default value that is dependent on the context of use, for instance a will use a default usage of AudioAttributesCompat#USAGE_MEDIA. See also AudioAttributes.Builder.

Summary

Public constructors
<init>() Constructs a new Builder with the defaults.
<init>(aa: AudioAttributesCompat!) Constructs a new Builder from a given AudioAttributes

Public methods
open AudioAttributesCompat!	build() Combines all of the attributes that have been set and return a new object.
open AudioAttributesCompat.Builder!	setContentType(contentType: Int) Sets the attribute describing the content type of the audio signal, such as speech, or music.
open AudioAttributesCompat.Builder!	setFlags(flags: Int) Sets the combination of flags.
open AudioAttributesCompat.Builder!	setLegacyStreamType(streamType: Int) Create an AudioAttributesCompat that best approximates the specified stream type constant.
open AudioAttributesCompat.Builder!	setUsage(usage: Int) Sets the attribute describing what is the intended use of the the audio signal, such as alarm or ringtone.

Public constructors

<init>

Builder()

Constructs a new Builder with the defaults. By default, usage and content type are respectively AudioAttributesCompat#USAGE_UNKNOWN and , and flags are 0. It is recommended to configure the usage (with setUsage(int)) or deriving attributes from a legacy stream type (with setLegacyStreamType(int)) before calling build() to override any default playback behavior in terms of routing and volume management.

<init>

Builder(aa: AudioAttributesCompat!)

Constructs a new Builder from a given AudioAttributes

Parameters
aa	AudioAttributesCompat!: the AudioAttributesCompat object whose data will be reused in the new Builder.

Public methods

build

open fun build(): AudioAttributesCompat!

Combines all of the attributes that have been set and return a new object.

Return
AudioAttributesCompat!: a new AudioAttributesCompat object

setContentType

open fun setContentType(contentType: Int): AudioAttributesCompat.Builder!

Sets the attribute describing the content type of the audio signal, such as speech, or music.
