Class Overview

This class provides methods to play DTMF tones (ITU-T Recommendation Q.23), call supervisory tones (3GPP TS 22.001, CEPT) and proprietary tones (3GPP TS 31.111). Depending on call state and routing options, tones are mixed to the downlink audio or output to the speaker phone or headset. This API is not for generating tones over the uplink audio path.

Public Constructors

public ToneGenerator (int streamType, int volume)

Added in API level 1

ToneGenerator class contructor specifying output stream type and volume.

Parameters
streamType int: The streame type used for tone playback (e.g. STREAM_MUSIC).
volume int: The volume of the tone, given in percentage of maximum volume (from 0-100).

Public Methods

public final int getAudioSessionId ()

Added in API level 16

Returns the audio session ID.

Returns
int the ID of the audio session this ToneGenerator belongs to or 0 if an error occured.

public void release ()

Added in API level 1

Releases resources associated with this ToneGenerator object. It is good practice to call this method when you're done using the ToneGenerator.

public boolean startTone (int toneType, int durationMs)

Added in API level 5

This method starts the playback of a tone of the specified type for the specified duration.

Parameters
toneType int: The type of tone generated @see startTone(int).
durationMs int: The tone duration in milliseconds. If the tone is limited in time by definition, the actual duration will be the minimum of durationMs and the defined tone duration. Setting durationMs to -1, is equivalent to calling startTone(int).
Returns
boolean

public boolean startTone (int toneType)

Added in API level 1

This method starts the playback of a tone of the specified type. only one tone can play at a time: if a tone is playing while this method is called, this tone is stopped and replaced by the one requested.

Parameters
toneType int: The type of tone generated chosen from the following list:
Returns
boolean

public void stopTone ()

Added in API level 1

This method stops the tone currently playing playback.

Protected Methods

protected void finalize ()

Added in API level 1

Invoked when the garbage collector has detected that this instance is no longer reachable. The default implementation does nothing, but this method can be overridden to free resources.

Note that objects that override finalize are significantly more expensive than objects that don't. Finalizers may be run a long time after the object is no longer reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup. Note also that finalizers are run on a single VM-wide finalizer thread, so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary for a class that has a native peer and needs to call a native method to destroy that peer. Even then, it's better to provide an explicit close method (and implement Closeable), and insist that callers manually dispose of instances. This works well for something like files, but less well for something like a BigInteger where typical calling code would have to deal with lots of temporaries. Unfortunately, code that creates lots of temporaries is the worst kind of code from the point of view of the single finalizer thread.

If you must use finalizers, consider at least providing your own ReferenceQueue and having your own thread process that queue.

Unlike constructors, finalizers are not automatically chained. You are responsible for calling super.finalize() yourself.

Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.
