    You can assign values to an instance using dot notation. This syntax for selecting a variable from a module, such as math.pi or string.uppercase. In this case, though, we are assigning values to named elements of an object. These elements are called attributes. The following diagram shows the result of these assignments. A state diagram that shows an object and its attributes is called an object diagram:

                             

    The variable blank refers to a Point object, which contains two attributes. Each attribute refers to a floating-point number. The expression blank.x means, ‘Go to the object blank refers to and get the value of x’. In this case, we assign that value to a variable named x. There is no conflict between the variable x and the attribute x. You can use dot notation as part of any expression. And you can pass an instance as an argument in the usual way. For example:

     

    Inside the function, p is an alias for blank, so if the function modifies p, blank changes.

    Audio Attributes

    Audio players support attributes that define how the audio system handles routing, volume, and focus decisions for the specified source. Applications can attach attributes to an audio playback (such as music played by a streaming service or a notification for a new email) then pass the audio source attributes to the framework, where the audio system uses the attributes to make mixing decisions and to notify applications about the state of the system.

    Note: Applications can also attach attributes to an audio recording (such as audio captured in a video recording), but this functionality is not exposed in the public API.

    In Android 4.4 and earlier, the framework made mixing decisions using only the audio stream type. However, basing such decisions on stream type was too limiting to produce quality output across multiple applications and devices. For example, on a mobile device, some applications (i.e. Google Maps) played driving directions on the STREAM_MUSIC stream type; however, on mobile devices in projection mode (i.e. Android Auto), applications cannot mix driving directions with other media streams.

    Using the audio attribute API, applications can now provide the audio system with detailed information about a specific audio source:

    • Usage. Specifies why the source is playing and controls routing, focus, and volume decisions.
    • Content type. Specifies what the source is playing (music, movie, speech, sonification, unknown).
    • Flags. Specifies how the source should be played. Includes support for audibility enforcement (camera shutter sounds required in some countries) and hardware audio/video synchronization.

    For dynamics processing, applications must distinguish between movie, music, and speech content. Information about the data itself may also matter, such as loudness and peak sample value.

    Using attributes


    Usage specifies the context in which the stream is used, providing information about why the sound is playing and what the sound is used for. Usage information is more expressive than a stream type and allows platforms or routing policies to refine volume or routing decisions.

    Supply one of the following usage values for any instance:

    • USAGE_UNKNOWN
    • USAGE_MEDIA
    • USAGE_VOICE_COMMUNICATION
    • USAGE_VOICE_COMMUNICATION_SIGNALLING
    • USAGE_ALARM
    • USAGE_NOTIFICATION
    • USAGE_NOTIFICATION_RINGTONE
    • USAGE_NOTIFICATION_COMMUNICATION_INSTANT
    • USAGE_NOTIFICATION_COMMUNICATION_DELAYED
    • USAGE_NOTIFICATION_EVENT
    • USAGE_ASSISTANCE_ACCESSIBILITY
    • USAGE_ASSISTANCE_NAVIGATION_GUIDANCE
    • USAGE_ASSISTANCE_SONIFICATION
    • USAGE_GAME

    Audio attribute usage values are mutually exclusive. For examples, refer to USAGE_MEDIA and USAGE_ALARM definitions; for exceptions, refer to the AudioAttributes.Builder definition.

    Content type


    Content type defines what the sound is and expresses the general category of the content such as movie, speech, or beep/ringtone. The audio framework uses content type information to selectively configure audio post-processing blocks. While supplying the content type is optional, you should include type information whenever the content type is known, such as using CONTENT_TYPE_MOVIE for a movie streaming service or CONTENT_TYPE_MUSIC for a music playback application.

    Supply one of the following content type values for any instance:

    • CONTENT_TYPE_UNKNOWN (default)
    • CONTENT_TYPE_MOVIE
    • CONTENT_TYPE_MUSIC
    • CONTENT_TYPE_SONIFICATION
    • CONTENT_TYPE_SPEECH

    Audio attribute content type values are mutually exclusive. For details on content types, refer to the audio attribute API.

    Flags


    Flags specify how the audio framework applies effects to the audio playback. Supply one or more of the following flags for an instance:

    • FLAG_AUDIBILITY_ENFORCED. Requests the system ensure the audibility of the sound. Use to address the needs of legacy STREAM_SYSTEM_ENFORCED (such as forcing camera shutter sounds).
    • HW_AV_SYNC. Requests the system select an output stream that supports hardware A/V synchronization.

    Audio attribute flags are non-exclusive (can be combined). For details on these flags, refer to the audio attribute API.

    Example


    In this example, AudioAttributes.Builder defines the AudioAttributes to be used by a new AudioTrack instance:

    AudioTrack myTrack = new AudioTrack(
      new AudioAttributes.Builder()
     .setUsage(AudioAttributes.USAGE_MEDIA)
        .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
        .build(),
      myFormat, myBuffSize, AudioTrack.MODE_STREAM, mySession);

    Compatibility


    Application developers should use audio attributes when creating or updating applications for Android 5.0. However, applications are not required to take advantage of attributes; they can handle legacy stream types only or remain unaware of attributes (i.e. a generic media player that doesn't know anything about the content it's playing).

    In such cases, the framework maintains backwards compatibility with older devices and Android releases by automatically translating legacy audio stream types to audio attributes. However, the framework does not enforce or guarantee this mapping across devices, manufacturers, or Android releases.

    Compatibility mappings:

    FLAG_AUDIBILITY_ENFORCED (@hide) STREAM_SYSTEM_ENFORCED

    Note: @hide streams are used internally by the framework but are not part of the public API.
