const val AUDIOFOCUS_GAIN = 1: Int

Used to indicate a gain of audio focus, or a request of audio focus, of unknown duration.

const val AUDIOFOCUS_GAIN_TRANSIENT = 2: Int

Used to indicate a temporary gain or request of audio focus, anticipated to last a short amount of time. Examples of temporary changes are the playback of driving directions, or an event notification.

const val AUDIOFOCUS_GAIN_TRANSIENT_EXCLUSIVE = 4: Int

Used to indicate a temporary request of audio focus, anticipated to last a short amount of time, during which no other applications, or system components, should play anything. Examples of exclusive and transient audio focus requests are voice memo recording and speech recognition, during which the system shouldn't play any notifications, and media playback should have paused.

const val AUDIOFOCUS_GAIN_TRANSIENT_MAY_DUCK = 3: Int

Used to indicate a temporary request of audio focus, anticipated to last a short amount of time, and where it is acceptable for other audio applications to keep playing after having lowered their output level (also referred to as "ducking"). Examples of temporary changes are the playback of driving directions where playback of music in the background is acceptable.

const val AUDIOFOCUS_NONE = 0: Int

Used to indicate no audio focus has been gained or lost, or requested.

java-static fun abandonAudioFocusRequest(
    audioManager: AudioManager!,
    focusRequest: AudioFocusRequestCompat!
): Int

Abandon audio focus. Causes the previous focus owner, if any, to receive focus.

synchronized java-static fun getAudioManager(context: Context!): AudioManager!

Returns the AudioManager.

This method avoids potential threading issues where AudioManager keeps access to the thread it was created on until after this thread is stopped.

It is recommended to use this method from a background thread.

    @C.StreamType streamType: Int
): @IntRange(from = 0) Int

java-static fun getStreamMinVolume(
    audioManager: AudioManager!,
    @C.StreamType streamType: Int
): @IntRange(from = 0) Int

Returns the minimum volume index for a particular stream.

java-static fun getStreamVolume(audioManager: AudioManager!, @C.StreamType streamType: Int): Int

Returns the current volume for a particular stream.

java-static fun isStreamMute(audioManager: AudioManager!, @C.StreamType streamType: Int): Boolean
