AudioAttributesCompat.Builder

public Builder()

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

public Builder(AudioAttributesCompat aa)

Constructs a new Builder from a given AudioAttributes

public AudioAttributesCompat build()

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

public AudioAttributesCompat.Builder setContentType(int contentType)

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

public AudioAttributesCompat.Builder setFlags(int flags)

Sets the combination of flags.

This is a bitwise OR with the existing flags.

public AudioAttributesCompat.Builder setLegacyStreamType(int streamType)

Sets attributes as inferred from the legacy stream types.

Warning: do not use this method in combination with setting any other attributes such as usage, content type, or flags, as this method will overwrite (the more accurate) information describing the use case previously set in the Builder. In general, avoid using it and prefer setting usage and content type directly with setUsage and setContentType.

Use this method when building an AudioAttributes instance to initialize some of the attributes by information derived from a legacy stream type.

public AudioAttributesCompat.Builder setUsage(int usage)

Sets the attribute describing what is the intended use of the the audio signal, such as alarm or ringtone.
