/**
|
|
* A class to encapsulate a collection of attributes describing information about an audio
|
|
* stream.
|
|
* <p><code>AudioAttributes</code> supersede the notion of stream types (see for instance
|
|
* {@link AudioManager#STREAM_MUSIC} or {@link AudioManager#STREAM_ALARM}) for defining the
|
|
* behavior of audio playback. Attributes allow an application to specify more information than is
|
|
* conveyed in a stream type by allowing the application to define:
|
|
* <ul>
|
|
* <li>usage: "why" you are playing a sound, what is this sound used for. This is achieved with
|
|
* the "usage" information. Examples of usage are {@link #USAGE_MEDIA} and {@link #USAGE_ALARM}.
|
|
* These two examples are the closest to stream types, but more detailed use cases are
|
|
* available. Usage information is more expressive than a stream type, and allows certain
|
|
* platforms or routing policies to use this information for more refined volume or routing
|
|
* decisions. Usage is the most important information to supply in <code>AudioAttributes</code>
|
|
* and it is recommended to build any instance with this information supplied, see
|
|
* {@link AudioAttributes.Builder} for exceptions.</li>
|
|
* <li>content type: "what" you are playing. The content type expresses the general category of
|
|
* the content. This information is optional. But in case it is known (for instance
|
|
* {@link #CONTENT_TYPE_MOVIE} for a movie streaming service or {@link #CONTENT_TYPE_MUSIC} for
|
|
* a music playback application) this information might be used by the audio framework to
|
|
* selectively configure some audio post-processing blocks.</li>
|
|
* <li>flags: "how" is playback to be affected, see the flag definitions for the specific playback
|
|
* behaviors they control. </li>
|
|
* </ul>
|
|
* <p><code>AudioAttributes</code> are used for example in one of the {@link AudioTrack}
|
|
* constructors (see {@link AudioTrack#AudioTrack(AudioAttributes, AudioFormat, int, int, int)}),
|
|
* to configure a {@link MediaPlayer}
|
|
* (see {@link MediaPlayer#setAudioAttributes(AudioAttributes)} or a
|
|
* {@link android.app.Notification} (see {@link android.app.Notification#audioAttributes}). An
|
|
* <code>AudioAttributes</code> instance is built through its builder,
|
|
* {@link AudioAttributes.Builder}.
