Request audio focus. Send a request to obtain the audio focus

Parameters
l AudioManager.OnAudioFocusChangeListener: the listener to be notified of audio focus changes

streamType int: the main audio stream type affected by the focus request

durationHint int: use AUDIOFOCUS_GAIN_TRANSIENT to indicate this focus request is temporary, and focus will be abandonned shortly. Examples of transient requests are for the playback of driving directions, or notifications sounds. Use AUDIOFOCUS_GAIN_TRANSIENT_MAY_DUCK to indicate also that it's ok for the previous focus owner to keep playing if it ducks its audio output. Alternatively use AUDIOFOCUS_GAIN_TRANSIENT_EXCLUSIVE for a temporary request that benefits from the system not playing disruptive sounds like notifications, for usecases such as voice memo recording, or speech recognition. Use AUDIOFOCUS_GAIN for a focus request of unknown duration such as the playback of a song or a video.

Returns
int AUDIOFOCUS_REQUEST_FAILED or AUDIOFOCUS_REQUEST_GRANTED

setAllowedCapturePolicy

Added in API level 29
public void setAllowedCapturePolicy (int capturePolicy)

Specifies whether the audio played by this app may or may not be captured by other apps or the system. The default is AudioAttributes#ALLOW_CAPTURE_BY_ALL. There are multiple ways to set this policy:

The most restrictive policy is always applied. See AudioPlaybackCaptureConfiguration for more details on which audio signals can be captured.

Parameters
capturePolicy int: one of AudioAttributes#ALLOW_CAPTURE_BY_ALL, AudioAttributes#ALLOW_CAPTURE_BY_SYSTEM, AudioAttributes#ALLOW_CAPTURE_BY_NONE. Value is AudioAttributes.ALLOW_CAPTURE_BY_ALL, AudioAttributes.ALLOW_CAPTURE_BY_SYSTEM, or AudioAttributes.ALLOW_CAPTURE_BY_NONE

setBluetoothA2dpOn

Added in API level 3
Deprecated in API level 15
public void setBluetoothA2dpOn (boolean on)

This method was deprecated in API level 15.
Use MediaRouter#selectRoute instead.

Parameters
on boolean

setBluetoothScoOn

Added in API level 1
public void setBluetoothScoOn (boolean on)

Request use of Bluetooth SCO headset for communications.

This method should only be used by applications that replace the platform-wide management of audio settings or the main telephony application.

Parameters
on boolean: set true to use bluetooth SCO for communications; false to not use bluetooth SCO for communications

setCommunicationDevice

Added in API level 31
public boolean setCommunicationDevice (AudioDeviceInfo device)

Selects the audio device that should be used for communication use cases, for instance voice or video calls. This method can be used by voice or video chat applications to select a different audio device than the one selected by default by the platform.

The device selection is expressed as an AudioDeviceInfo among devices returned by getAvailableCommunicationDevices(). Note that only devices in a sink role (AKA output devices, see AudioDeviceInfo#isSink()) can be specified. The matching source device is selected automatically by the platform.

The selection is active as long as the requesting application process lives, until clearCommunicationDevice() is called or until the device is disconnected. It is therefore important for applications to clear the request when a call ends or the the requesting activity or service is stopped or destroyed.

In case of simultaneous requests by multiple applications the priority is given to the application currently controlling the audio mode (see setMode(int)). This is the latest application having selected mode MODE_IN_COMMUNICATION or mode MODE_IN_CALL. Note that MODE_IN_CALL can only be selected by the main telephony application with permission Manifest.permission#MODIFY_PHONE_STATE.

If the requested devices is not currently available, the request will be rejected and the method will return false.

This API replaces the following deprecated APIs:

Example

The example below shows how to enable and disable speakerphone mode.

 // Get an AudioManager instance
 AudioManager audioManager = Context.getSystemService(AudioManager.class);
 AudioDeviceInfo speakerDevice = null;
 List devices = audioManager.getAvailableCommunicationDevices();
 for (AudioDeviceInfo device : devices) {
     if (device.getType() == AudioDeviceInfo.TYPE_BUILTIN_SPEAKER) {
         speakerDevice = device;
         break;
     }
 }
 if (speakerDevice != null) {
     // Turn speakerphone ON.
     boolean result = audioManager.setCommunicationDevice(speakerDevice);
     if (!result) {
         // Handle error.
     }
     // Turn speakerphone OFF.
     audioManager.clearCommunicationDevice();
 }
 

Parameters
device AudioDeviceInfo: the requested audio device. This value cannot be null.

Returns
boolean true if the request was accepted, false otherwise.

Throws
IllegalArgumentException If an invalid device is specified.

setEncodedSurroundMode

Added in API level 31
public boolean setEncodedSurroundMode (int mode)

Requires Manifest.permission.WRITE_SETTINGS

Parameters
mode int: Value is ENCODED_SURROUND_OUTPUT_UNKNOWN, ENCODED_SURROUND_OUTPUT_AUTO, ENCODED_SURROUND_OUTPUT_NEVER, ENCODED_SURROUND_OUTPUT_ALWAYS, or ENCODED_SURROUND_OUTPUT_MANUAL

Returns
boolean true if successful, otherwise false

setMicrophoneMute

Added in API level 1
public void setMicrophoneMute (boolean on)

Sets the microphone mute on or off.

This method should only be used by applications that replace the platform-wide management of audio settings or the main telephony application.

Parameters
on boolean: set true to mute the microphone; false to turn mute off

setMode

Added in API level 1
public void setMode (int mode)

Sets the audio mode.

The audio mode encompasses audio routing AND the behavior of the telephony layer. Therefore this method should only be used by applications that replace the platform-wide management of audio settings or the main telephony application. In particular, the MODE_IN_CALL mode should only be used by the telephony application when it places a phone call, as it will cause signals from the radio layer to feed the platform mixer.

Parameters
mode int: the requested audio mode. Informs the HAL about the current audio state so that it can route the audio appropriately. Value is MODE_NORMAL, MODE_RINGTONE, MODE_IN_CALL, MODE_IN_COMMUNICATION, MODE_CALL_SCREENING, MODE_CALL_REDIRECT, or MODE_COMMUNICATION_REDIRECT

setParameters

Added in API level 5
public void setParameters (String keyValuePairs)

Sets a variable number of parameter values to audio hardware.

Parameters
keyValuePairs String: list of parameters key value pairs in the form: key1=value1;key2=value2;...

setPreferredMixerAttributes

Added in API level 34
public boolean setPreferredMixerAttributes (AudioAttributes attributes, 
                AudioDeviceInfo device, 
                AudioMixerAttributes mixerAttributes)

Configures the mixer attributes for a particular AudioAttributes over a given AudioDeviceInfo.

Call getSupportedMixerAttributes(android.media.AudioDeviceInfo) to determine which mixer attributes can be used with the given device.

The ownership of preferred mixer attributes is recognized by uid. When a playback from the same uid is routed to the given audio device when calling this API, the output mixer/stream will be configured with the values previously set via this API.

Use clearPreferredMixerAttributes(android.media.AudioAttributes, android.media.AudioDeviceInfo) to cancel setting mixer attributes for this AudioAttributes.
Requires Manifest.permission.MODIFY_AUDIO_SETTINGS

Parameters
attributes AudioAttributes: the AudioAttributes whose mixer attributes should be set. Currently, only AudioAttributes#USAGE_MEDIA is supported. When playing audio targeted at the given device, use the same attributes for playback. This value cannot be null.

device AudioDeviceInfo: the device to be routed. Currently, only USB device will be allowed. This value cannot be null.

mixerAttributes AudioMixerAttributes: the preferred mixer attributes. When playing audio targeted at the given device, use the same AudioFormat for both playback and the mixer attributes. This value cannot be null.

Returns
boolean true only if the preferred mixer attributes are set successfully.

setRingerMode

Added in API level 1
public void setRingerMode (int ringerMode)

Sets the ringer mode.

Silent mode will mute the volume and will not vibrate. Vibrate mode will mute the volume and vibrate. Normal mode will be audible and may vibrate according to user settings.

This method has no effect if the device implements a fixed volume policy as indicated by isVolumeFixed(). *

From N onward, ringer mode adjustments that would toggle Do Not Disturb are not allowed unless the app has been granted Do Not Disturb Access. See NotificationManager#isNotificationPolicyAccessGranted().

Parameters
ringerMode int: The ringer mode, one of RINGER_MODE_NORMAL, RINGER_MODE_SILENT, or RINGER_MODE_VIBRATE.

setRouting

Added in API level 1
Deprecated in API level 15
public void setRouting (int mode, 
                int routes, 
                int mask)

This method was deprecated in API level 15.
Do not set audio routing directly, use setSpeakerphoneOn(), setBluetoothScoOn() methods instead.

Sets the audio routing for a specified mode

Parameters
mode int: audio mode to change route. E.g., MODE_RINGTONE.

routes int: bit vector of routes requested, created from one or more of ROUTE_xxx types. Set bits indicate that route should be on

mask int: bit vector of routes to change, created from one or more of ROUTE_xxx types. Unset bits indicate the route should be left unchanged

setSpeakerphoneOn

Added in API level 1
Deprecated in API level 34
public void setSpeakerphoneOn (boolean on)

This method was deprecated in API level 34.
Use AudioManager#setCommunicationDevice(AudioDeviceInfo) or AudioManager#clearCommunicationDevice() instead.

Sets the speakerphone on or off.

This method should only be used by applications that replace the platform-wide management of audio settings or the main telephony application.

Parameters
on boolean: set true to turn on speakerphone; false to turn it off

setStreamMute

Added in API level 1
Deprecated in API level 23
public void setStreamMute (int streamType, 
                boolean state)

This method was deprecated in API level 23.
Use adjustStreamVolume(int, int, int) with ADJUST_MUTE or ADJUST_UNMUTE instead.

Mute or unmute an audio stream.

This method should only be used by applications that replace the platform-wide management of audio settings or the main telephony application.

This method has no effect if the device implements a fixed volume policy as indicated by isVolumeFixed().

This method was deprecated in API level 22. Prior to API level 22 this method had significantly different behavior and should be used carefully. The following applies only to pre-22 platforms:

  • The mute command is protected against client process death: if a process with an active mute request on a stream dies, this stream will be unmuted automatically.
  • The mute requests for a given stream are cumulative: the AudioManager can receive several mute requests from one or more clients and the stream will be unmuted only when the same number of unmute requests are received.
  • For a better user experience, applications MUST unmute a muted stream in onPause() and mute is again in onResume() if appropriate.

Parameters
streamType int: The stream to be muted/unmuted.

state boolean: The required mute state: true for mute ON, false for mute OFF

Parameters
streamType int: The stream to be soloed/unsoloed.

state boolean: The required solo state: true for solo ON, false for solo OFF

See also:

setStreamVolume

Added in API level 1
public void setStreamVolume (int streamType, 
                int index, 
                int flags)

Sets the volume index for a particular stream.

This method has no effect if the device implements a fixed volume policy as indicated by isVolumeFixed().

From N onward, volume adjustments that would toggle Do Not Disturb are not allowed unless the app has been granted Do Not Disturb Access. See NotificationManager#isNotificationPolicyAccessGranted().

Parameters
streamType int: The stream whose volume index should be set.

index int: The volume index to set. See getStreamMaxVolume(int) for the largest valid value.

flags int: Value is either 0 or a combination of FLAG_SHOW_UI, FLAG_ALLOW_RINGER_MODES, FLAG_PLAY_SOUND, FLAG_REMOVE_SOUND_AND_VIBRATE, and FLAG_VIBRATE

Throws
SecurityException if the volume change triggers a Do Not Disturb change and the caller is not granted notification policy access.

setSurroundFormatEnabled

Added in API level 31
public boolean setSurroundFormatEnabled (int audioFormat, 
                boolean enabled)

Sets and persists a certain surround format as enabled or not.

This API is called by TvSettings surround sound menu when user enables or disables a surround sound format. This setting is persisted as global user setting. Applications should revert their changes to surround sound settings unless they intend to modify the global user settings across all apps. The framework does not auto-revert an application's settings after a lifecycle event. Audio focus is not required to apply these settings.

setVibrateSetting

Added in API level 1
Deprecated in API level 16
public void setVibrateSetting (int vibrateType, 
                int vibrateSetting)

This method was deprecated in API level 16.
Applications should maintain their own vibrate policy based on current ringer mode that can be queried via getRingerMode().

Sets the setting for when the vibrate type should vibrate.

Parameters
vibrateType int: The type of vibrate. One of VIBRATE_TYPE_NOTIFICATION or VIBRATE_TYPE_RINGER.

vibrateSetting int: The vibrate setting, one of VIBRATE_SETTING_ON, VIBRATE_SETTING_OFF, or VIBRATE_SETTING_ONLY_SILENT.

setWiredHeadsetOn

Added in API level 5
Deprecated in API level 15
public void setWiredHeadsetOn (boolean on)

This method was deprecated in API level 15.
Do not use.

Parameters
on boolean: set true to route audio to/from wired headset; false disable wired headset audio

shouldVibrate

Added in API level 1
Deprecated in API level 16
public boolean shouldVibrate (int vibrateType)

This method was deprecated in API level 16.
Applications should maintain their own vibrate policy based on current ringer mode that can be queried via getRingerMode().

Returns whether a particular type should vibrate according to user settings and the current ringer mode.

This shouldn't be needed by most clients that use notifications to vibrate. The notification manager will not vibrate if the policy doesn't allow it, so the client should always set a vibrate pattern and let the notification manager control whether or not to actually vibrate.

Parameters
vibrateType int: The type of vibrate. One of VIBRATE_TYPE_NOTIFICATION or VIBRATE_TYPE_RINGER.

Returns
boolean Whether the type should vibrate at the instant this method is called.

startBluetoothSco

Added in API level 8
Deprecated in API level 34
public void startBluetoothSco ()

This method was deprecated in API level 34.
Use AudioManager#setCommunicationDevice(AudioDeviceInfo) instead.

Start bluetooth SCO audio connection.

Requires Permission: Manifest.permission#MODIFY_AUDIO_SETTINGS.

This method can be used by applications wanting to send and received audio to/from a bluetooth SCO headset while the phone is not in call.

As the SCO connection establishment can take several seconds, applications should not rely on the connection to be available when the method returns but instead register to receive the intent ACTION_SCO_AUDIO_STATE_UPDATED and wait for the state to be SCO_AUDIO_STATE_CONNECTED.

As the ACTION_SCO_AUDIO_STATE_UPDATED intent is sticky, the application can check the SCO audio state before calling startBluetoothSco() by reading the intent returned by the receiver registration. If the state is already CONNECTED, no state change will be received via the intent after calling startBluetoothSco(). It is however useful to call startBluetoothSco() so that the connection stays active in case the current initiator stops the connection.

Unless the connection is already active as described above, the state will always transition from DISCONNECTED to CONNECTING and then either to CONNECTED if the connection succeeds or back to DISCONNECTED if the connection fails (e.g no headset is connected).

When finished with the SCO connection or if the establishment fails, the application must call stopBluetoothSco() to clear the request and turn down the bluetooth connection.

Even if a SCO connection is established, the following restrictions apply on audio output streams so that they can be routed to SCO headset:

  • the stream type must be STREAM_VOICE_CALL
  • the format must be mono
  • the sampling must be 16kHz or 8kHz

The following restrictions apply on input streams:

  • the format must be mono
  • the sampling must be 8kHz

Note that the phone application always has the priority on the usage of the SCO connection for telephony. If this method is called while the phone is in call it will be ignored. Similarly, if a call is received or sent while an application is using the SCO connection, the connection will be lost for the application and NOT returned automatically when the call ends.

NOTE: up to and including API version Build.VERSION_CODES.JELLY_BEAN_MR1, this method initiates a virtual voice call to the bluetooth headset. After API version Build.VERSION_CODES.JELLY_BEAN_MR2 only a raw SCO audio connection is established.

stopBluetoothSco

Added in API level 8
Deprecated in API level 34
public void stopBluetoothSco ()

This method was deprecated in API level 34.
Use AudioManager#clearCommunicationDevice() instead.

Stop bluetooth SCO audio connection.

Requires Permission: Manifest.permission#MODIFY_AUDIO_SETTINGS.
