                               int flags)

Adjusts the volume of a particular stream by one step in a direction.

Parameters:

adjustVolume

public void adjustVolume(int direction,
                         int flags)

Adjusts the volume of the most relevant stream. For example, if a call is active, it will have the highest priority regardless of if the in-call screen is showing. Another example, if music is playing in the background and a call is not active, the music stream will be adjusted.

Parameters:

direction - The direction to adjust the volume. One of ADJUST_LOWER, ADJUST_RAISE, or ADJUST_SAME.

flags - One or more flags.

See Also:

adjustSuggestedStreamVolume(int, int, int), adjustStreamVolume(int, int, int), setStreamVolume(int, int, int)

public void adjustSuggestedStreamVolume(int direction,
                                        int suggestedStreamType,
                                        int flags)

Adjusts the volume of the most relevant stream, or the given fallback stream.

Parameters:

direction - The direction to adjust the volume. One of ADJUST_LOWER, ADJUST_RAISE, or ADJUST_SAME.

suggestedStreamType - The stream type that will be used if there isn't a relevant stream. USE_DEFAULT_STREAM_TYPE is valid here.

flags - One or more flags.

See Also:

adjustVolume(int, int), adjustStreamVolume(int, int, int), setStreamVolume(int, int, int)

getRingerMode

public int getRingerMode()

Returns the current ringtone mode.

Returns:

The current ringtone mode, one of RINGER_MODE_NORMAL, RINGER_MODE_SILENT, or RINGER_MODE_VIBRATE.

Returns:

The current volume index for the stream.

See Also:

getStreamMaxVolume(int), setStreamVolume(int, int, int)

setRingerMode

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.

Parameters:

ringerMode - The ringer mode, one of RINGER_MODE_NORMAL, RINGER_MODE_SILENT, or RINGER_MODE_VIBRATE.

See Also:

getRingerMode()

                            int index,
                            int flags)

Sets the volume index for a particular stream.

Parameters:

streamType - The stream whose volume index should be set.

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

flags - One or more flags.

See Also:

getStreamMaxVolume(int), getStreamVolume(int)

setStreamSolo

public void setStreamSolo(int streamType,
                          boolean state)

Solo or unsolo a particular stream. All other streams are muted.

The solo command is protected against client process death: if a process with an active solo request on a stream dies, all streams that were muted because of this request will be unmuted automatically.

The solo requests for a given stream are cumulative: the AudioManager can receive several solo requests from one or more clients and the stream will be unsoloed only when the same number of unsolo requests are received.

For a better user experience, applications MUST unsolo a soloed stream in onPause() and solo is again in onResume() if appropriate.

Parameters:

streamType - The stream to be soloed/unsoloed.

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

setStreamMute

public void setStreamMute(int streamType,
                          boolean state)

Mute or unmute an audio stream.

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 - The stream to be muted/unmuted.

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

shouldVibrate

public boolean shouldVibrate(int vibrateType)

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 - The type of vibrate. One of VIBRATE_TYPE_NOTIFICATION or VIBRATE_TYPE_RINGER.

Returns:

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

This shouldn't be needed by most clients that want to vibrate, instead see shouldVibrate(int).

Parameters:

vibrateType - The type of vibrate. One of VIBRATE_TYPE_NOTIFICATION or VIBRATE_TYPE_RINGER.

Returns:

The vibrate setting, one of VIBRATE_SETTING_ON, VIBRATE_SETTING_OFF, or VIBRATE_SETTING_ONLY_SILENT.

See Also:

setVibrateSetting(int, int), shouldVibrate(int)

setVibrateSetting

public void setVibrateSetting(int vibrateType,
                              int vibrateSetting)
