| ↳ | android.media.ToneGenerator |
*** ** * ** ***
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
### ToneGenerator
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public ToneGenerator (int streamType,
int volume)
```
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
### getAudioSessionId
Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public final int getAudioSessionId ()
```
Returns the audio session ID.
| Returns ||
|---|---|
| `int` | the ID of the audio session this ToneGenerator belongs to or 0 if an error occured.
|
### release
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void release ()
```
Releases resources associated with this ToneGenerator object. It is good practice to call this method when you're done using the ToneGenerator.
### startTone
Added in [API level 5](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public boolean startTone (int toneType,
int durationMs)
```
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 `https://developer.android.com/reference/android/media/ToneGenerator#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 `https://developer.android.com/reference/android/media/ToneGenerator#startTone(int)`.
|
| Returns ||
|---|---|
| `boolean` |
|

## Protected methods
### finalize
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
protected void finalize ()
```
Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the `finalize` method to dispose of system resources or to perform other cleanup.
The general contract of `finalize` is that it is invoked if and when the Java virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The `finalize` method may take any action, including making this object available again to other threads; the usual purpose of `finalize`, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.
The `finalize` method of class `Object` performs no special action; it simply returns normally. Subclasses of `Object` may override this definition.
The Java programming language does not guarantee which thread will invoke the `finalize` method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.
After the `finalize` method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.
The `finalize` method is never invoked more than once by a Java virtual machine for any given object.
Any exception thrown by the `finalize` method causes the finalization of this object to be halted, but is otherwise ignored.
