Voice Android SDK Changelog
Welcome to the Programmable Voice Android SDK
The Twilio Programmable Voice SDKs allow you to add voice-over-IP (VoIP) calling into your native Android applications. See Android Getting Started Guide to begin using the SDK.
To make sure your app is ready for Android 11 please visit this page.
The Twilio Programmable Voice SDKs use Semantic Versioning. Twilio supports version N-1 for 12 months after the first GA release of version N. We recommend that you upgrade to the latest version as soon as possible to avoid any breaking changes. Version 5.x is the latest Android version.
Support for 4.x ceased October 28, 2020. This branch will no longer receive fixes for critical issues. Check out this guide when planning your migration to 5.x.
Support for 3.x ceased July 1, 2020. Please upgrade to the latest version.
Support for 2.x ceased on January 1, 2020. Please upgrade to the latest version.
End-of-Life for 1.x will occur on March 23, 2021. A two-hour maintenance period is planned for 1.x at 9am Pacific Time on January 26, 2021. Please upgrade to the latest version. See this EoL notice for further details.
6.3.0
Sept 5th, 2023
- Programmable Voice Android SDK 6.3.0[Maven Central], [docs] MD5 Checksum : a2e5f997dbf3c6b0e6b1a169e2cbf79d
API Updates
- Provides a
LoggerInterface
interface. This interface contains alog
method that is invoked with aLogParameters
object every time a log message becomes available. TheLogParameters
object contains all the information relevant to the log message being delivered. - The Android SDK internally implements the
LoggerInterface
to provide default logging capabilities to stdout using android.util.Log. - Provides a
Voice.SetLogger(LoggerInterface)
method that allows setting a custom logger that conforms toLoggerInterface
to which log messages will be delivered. - Provides a
Voice.GetLogger()
method that returns the logger that was previously set withsetLogger
. If no custom logger was set, this method returns the default logger currently used by the SDK. - Users can send their messages to be logged by the SDK using
Voice.GetLogger().log(LogParameters)
. This logs the message using the SDK's default logger. - Users can also implement custom loggers that conform to
LoggerInterface
to customize the logging mechanism, for eg., logging to a file, sending the logs to a server, etc. - The existing
Logger
class is deprecated and will be removed in the next major version release.

- Programmable Voice Android SDK 6.1.0[Maven Central], [docs] MD5 Checksum : 164b77f552b7a2a9c8c40ace9b30077f
API updates
- The Voice Android SDK now supports Twilio Regional by providing the home region specifier in the access token header when calling the
Voice.register()
method, theVoice.unregister()
method, or theVoice.connect()
method.
Existing customers can now migrate their Voice use-cases to data centers in Ireland or Australia to establish data residency within the region. In addition, new customers may now select Ireland or Australia as their region of choice for Voice related use cases. There is no additional cost to use the new data centers in Ireland or Australia. To learn more about Regional Voice, check out our blog post or head over to our developer docs to get started.
Below is an example of specifying home region in the access token using the Twilio Node.js helper library:
const accessToken = new twilio.jwt.AccessToken(
credentials.accountSid,
credentials.apiKeySid,
credentials.apiKeySecret, {
identity,
ttl,
region: 'au1',
},
);
The decoded header of your access token should look like this:
{
"alg": "HS256",
"typ": "JWT",
"cty": "twilio-fpa;v=1",
"twr": "au1"
}
Maintenance
- The SDK compileSDKVersion and targetSDKVersion were updated to 31.

5.3.0
June 3, 2020
API changes
- A new
Call.Listener
callbackonCallQualityWarningsChanged()
is introduced.
void onCallQualityWarningsChanged(Call call,
Set<CallQualityWarning> currentWarnings,
Set<CallQualityWarning> previousWarnings);
The Set
that contain the warnings are consisted of enum
with values of the newly introduced CallQualityWarning
public enum CallQualityWarning {
WARN_HIGH_RTT("high-rtt"),
WARN_HIGH_JITTER("high-jitter"),
WARN_HIGH_PACKET_LOSS("high-packet-loss"),
WARN_LOW_MOS("low-mos"),
WARN_CONSTANT_AUDIO_IN_LEVEL("constant-audio-input-level"),
}
The trigger conditions for the warnings defined in the enumeration are defined as follows:
WARN_HIGH_RTT
- Round Trip Time (RTT) > 400 ms for 3 out of last 5 samples.WARN_HIGH_JITTER
- Jitter > 30 ms for 3 out of last 5 samples.WARN_HIGH_PACKET_LOSS
- Raised when average packet loss > 3% in last 7 samples. Cleared when average packet loss <= 1% in last 7 samples.WARN_LOW_MOS
- Mean Opinion Score (MOS) < 3.5 for 3 out of last 5 samples.-
WARN_CONSTANT_AUDIO_IN_LEVEL
- Raised when the standard deviation of audio input levels for last 10 samples is less than or equals 1% of the maximum possible audio input level (32767) i.e. 327.67 and the call is not in the muted state and the call is not on hold. Cleared when the standard deviation of audio input levels for last 10 samples is greater than 3% of the maximum possible audio input level. -
A new method
getCallQualityWarnings()
is added toCall
to retrieve the present set of call quality related warnings. -
This release also adds the Mean Opinion Score (MOS) measurement
mos
toRemoteAudioTrackStats
. UseCall.getStats()
API during a call to retrieve the score. Themos
is computed once per second. Since the MOS is calculated from network performance measurements, it can be used to indicate the current network condition to the user to provide better usability. See API Docs for more information.
Example:
call.getStats(new StatsListener() {

- This release includes support for the expansion of Twilio’s Global Infrastructure via Edge Locations which allows customers to control their connectivity into and out of Twilio’s platform. The Voice Android SDK uses these Edges to connect to Twilio’s infrastructure via the new property
Voice.edge
. This new property supersedes the now deprecatedVoice.region
. See the new Edge names and how they map to the old region names.
Here is an example:
// Connect using global low latency
Voice.setEdge("roaming")
Below are the new methods signatures introduced in Voice
class.
@NonNull public static String getEdge();
public static void setEdge(@NonNull String edge)
The following APIs have been deprecated in favor of the new methods.
@NonNull public static String getRegion();
public static void setRegion(@NonNull String region)
- Added a boolean property
enableIceGatheringOnAnyAddressPorts
inCallOptions
that allows gathering of ICE candidates from "any address" ports. This allows applications to work in certain VPN environments.
Reference the following code snippet to enable or disable this feature. Note, enableIceGatheringOnAnyAddressPorts
is disabled by default.
Configure enableIceGatheringOnAnyAddressPorts
with ConnectOptions
ConnectOptions connectOptions = new ConnectOptions.Builder(accessToken)
.enableIceGatheringOnAnyAddressPorts(iceGatheringOnAnyAddressPorts)
.build();
Voice.connect(context, connectOptions, callListener);
Configure enableIceGatheringOnAnyAddressPorts
with AcceptOptions
AcceptOptions acceptOptions = new AcceptOptions.Builder()
.enableIceGatheringOnAnyAddressPorts(iceGatheringOnAnyAddressPorts)
.build();
callInvite.accept(context, acceptOptions, callListener);
- By default ICE gathering is done on all interfaces except some VPN type interfaces. This makes it impossible to connect to Twilio in networks that require the use of VPN. In this release, the new boolean property
enableIceGatheringOnAnyAddressPorts
inCallOptions
allows the gathering of ICE candidates from all available interfaces. This should be used in those networks where the default does not work. See AcceptOptions.Builder.enableIceGatheringOnAnyAddressPorts or ConnectOptions.Builder.enableIceGatheringOnAnyAddressPorts for more information.

AudioDevice API
The AudioDevice API is an advanced API that can be used to create innovative and sophisticated in-app audio capabilities. For example, enable pre-recorded messages to be played in-call, or apply noise reduction algorithms before playing out the received audio.
An AudioDevice
is a logical device that is used to capture and render audio. The captured audio is sent to the remote party, and the received audio is rendered locally. By default, the SDK uses DefaultAudioDevice which uses the mic for capturing and the local speaker/earpiece/headset for rendering. The AudioDevice
API allows for the creation of custom audio capturers and renderers. See this example and API docs to learn more about custom audio devices.
SDK size update
The AudioDevice
feature requires additional native APIs that result in a small increase in SDK size. The table below highlights the updated App Size Impact.

5.0.0
October 28, 2019
This release introduces an update to the Programmable Voice call model. To upgrade your application please follow the migration guide.
Background
Prior to 5.0.0
, when
Voice.register(...)
is invoked, the Voice SDK registers for two push
notifications: a call and cancel push notification. The call and cancel push notification payloads
could then be passed as arguments to Voice.handleMessage(...)
and your application would be
provided with a callback via MessageListener
indicating if the message was a CallInvite
or CancelledCallInvite
.
Starting with 5.0.0, when Voice.register(...)
is invoked, the Voice SDK will register
for call push notifications and cancelled call invites will be determined via a signaling connection.
Voice.handleMessage(...)
no longer processes cancel push notification payloads and will return
false
if provided with a cancel message. As a result, developers must re-register via
Voice.register(...)
after upgrading their application to 5.0.0
to stop receiving cancel push
notifications.
CallInvite and CancelledCallInvite updates
A valid call push notification, when passed to Voice.handleMessage(...)
, will still result in a CallInvite
being raised to the provided MessageListener
. A CancelledCallInvite
will be raised to
the provided MessageListener
if any of the following events occur:
- The call is prematurely disconnected by the caller.
- The callee does not accept or reject the call within 30 seconds.
- The Voice SDK is unable to establish a connection to Twilio.
A CancelledCallInvite
will not be raised if a CallInvite
is accepted or rejected.
Insights
To provide observability for incoming call cancellations the following Insights events have been added:
Event Group | Level | Event Name | Description |
---|---|---|---|
connection | INFO | listen | Raised when an attempt to listen for cancellations is made |
connection | INFO | listening | Raised when an attempt to listen for cancellations has succeeded |
connection | INFO | cancel | Raised when a cancellation has been reported |
connection | ERROR | listening-error | Raised when an attempt to listen for cancellation has failed |
registration | ERROR | unsupported-cancel-message-error | Raised when a "cancel" push notification is processed by the SDK. This version of the SDK does not support "cancel" push notifications |
API updates
-
MessageListener.onCancelledCallInvite
has been updated to the following signature.void onCancelledCallInvite(@NonNull CancelledCallInvite cancelledCallInvite, @Nullable CallException callException)
The provided
CallException
will indicate if a call was cancelled as the result of an error. If no error occurred, then theCallException
isnull
. -
Both
Voice.handleMessage(...)
methods require an AndroidContext
as the first argument. -
CallInvite
class includesisValid(...)
utility method to validate whether the payload is a valid notification sent by Twilio. A valid notification payload will result in aCallInvite
being raised viaMessageListener.onCallInvite(...)
callback when passed toVoice.handleMessage(...)
. -
Enabling insights and setting the region are now specified on the
Voice
class. These options were previously accessible onConnectOptions
andAcceptOptions
.- Sending stats data to Insights is enabled by default.
- The default region uses Global Low Latency routing, which establishes a connection with the closest region to the user.
Below are the new methods signatures introduced in
Voice
class.public static boolean isInsightsEnabled(); public static void enableInsights(boolean enable); @NonNull public static String getRegion(); public static void setRegion(@NonNull String region)
-
Introduced a new error code that gets surfaced when
handleMessage(..)
API is called with push notification bundle withtwilio.voice.cancel
as thetwi_message_type
.
Error Code | Level | Error Message | Description |
---|---|---|---|
31302 | Error | Unsupported Cancel Message Error | This version of the SDK no longer supports processing cancel push notification messages. You must register via Voice.register(...) with this version of the SDK to stop receiving cancel push notification messages. Cancellations are now handled internally and reported to you on behalf of the SDK. |

July 12th, 2019
New Features
Max Average Bandwidth API
By default, Opus codec is set up with a bitrate of around 32kbps (40-50kbps on the wire). With this release, you are able to set a custom max average bitrate transmission to better control how much bandwidth your VoIP application should use. See RFC-7587 7.1 for information about Max Average Bitrate.
The main purpose of this API is to set a lower max average bitrate to minimize bandwidth usage. This is particularly useful in deployments where bandwidth is a premium. Where bandwidth is not of concern, you do not need to use this API.
Max Average Bitrate can be set to as low as 6,000bps and as high as 51,000bps. Values outside this range are ignored and the default Opus operation mode is used. See API Docs for more information.
As would be expected, lowering the max average bitrate impacts audio quality. We don’t recommend setting max average bitrate to a value below 8,000bps. On the other hand, setting values over 32,000bps will have negligible audio quality improvements.
For example, to set a new max average bitrate to 16,000bps:
ConnectOptions connectOptions = new ConnectOptions.Builder(accessToken)
.params(params)
.preferAudioCodecs(Arrays.asList( new OpusCodec(16000)))
.build();
Call call = Voice.connect(VoiceActivity.this, connectOptions, callListener);
Other Enhancements
- Programmable Voice Android SDK transmits data for VoIP calls and for Insights. With this release, we have reduced Insights related data consumption by around 25%. This was accomplished by reducing the events reporting interval.
- The SDK now reports
ice-candidate
events to Insights. These events are raised whenOnIceCandidate
is called on thePeerConnection
.
Known Issues
- Restrictive networks may fail unless ICE servers are provided via
ConnectOptions.Builder.iceOptions(...)
orAcceptOptions.Builder.iceOptions(...)
. ICE servers can be obtained from Twilio Network Traversal Service. - Occasional native crash in

4.0.0
June 28th, 2019
New Features
Reconnecting State API
This release introduces the new Reconnecting State API
. This API adds a new state RECONNECTING
to Call.State
and two new Call.Listener()
callbacks, onReconnecting(...)
and onReconnected(...)
.
Call reconnection capability has been available since SDK 3.0. For example, if a call is established over a wifi network and the wifi network becomes unavailable, the SDK will automatically switch the call over to the next available network.
This release adds the reconnection related callbacks. onReconnecting(...)
indicates when a call is being reconnected due to a network disruption or network switch over and onReconnected(...)
is called once the call has been re-connected. You can use this information to provide intuitive feedback to your App user when a reconnection is taking place.

Improved error codes
We now surface more details about errors encountered during Voice.register(...), Voice.unregister(...), Voice.connect(...), and CallInvite.accept(...). Previously, these functions reported these errors with the generic error REGISTRATION_ERROR_CODE/31301 or EXCEPTION_CONNECTION_ERROR/31005.
With the new error codes, you can make more informed decisions about how to remedy the problem. For example, error code EXCEPTION_BAD_REQUEST
and EXCEPTION_TOO_MANY_REQUEST
indicate potential programming issues, while EXCEPTION_ACCESS_TOKEN_REJECTED
indicates an issue with your Access Token.
Please note, you may need to change your code if you have added special handling for REGISTRATION_ERROR_CODE/31301 or EXCEPTION_CONNECTION_ERROR/31005.
For more information see the API docs
The following is a summary of the new codes available for Voice.register(...)
and Voice.unregister(...)
:
Error Code | Error Message |

31403 | Forbidden |
31404 | Not Found |

Enhancements
API Changes:
- Nullability annotations have been added. Methods that expect
@NonNull
parameters throwNullPointerException
. Methods that validate parameters for a specified input throwIllegalStateException
if invalid. - Moved
CallState
toCall.State
- Provide a stateless mechanism for processing push messages related to call invites and call invite cancellations. This API no longer raises errors when processing invalid messages, instead a
boolean
value is returned whenhandleMessage(context, data)
is called. The boolean value istrue
when the provided data results in aCallInvite
orCancelledCallInvite
. IfhandleMessage(context, data)
returnsfalse
it means the data provided was not a Twilio Voice push message. TheCallInvite
has anaccept()
andreject()
method. While theCancelledCallInvite
simply provides theto
,from
, andcallSid
fields also available in theCallInvite
. The methodgetCallSid()
can be used to associate aCallInvite
with aCancelledCallInvite
. - Migrated the API
CallInvite
toCallInvite
andCancelledCallInvite
.
// Processing push messages in 2.X
handleMessage(context, data, new MessageListener() {
@Override
void onCallInvite(CallInvite callInvite) {
// Check state and process invite
if (callInvite.getState().equals(PENDING)) {
// Show notification to answer or reject call
} else if(callInvite.getState().equals(CANCELLED)) {
// Hide notification
}
}
@Override
void onError(MessageException messageException) {
// Invalid data was provided
}
});
// Processing push messages in 3.X
boolean handled = handleMessage(context, data, new MessageListener() {
@Override
void onCallInvite(CallInvite callInvite) {
// Show notification to answer or reject call
}
@Override
void onCancelledCallInvite(CancelledCallInvite callInvite) {
// Hide notification
}
});
if(!handled) {
// This message is not a Twilio voice push message
}
- Introduced
call.getStats()
method that returns a list ofStatsReport
with metrics for all the audio tracks in a call.
call.getStats(new StatsListener() {
@Override
public void onStats(@NonNull List<StatsReport> statsReports) {
// Process statsReports
}
});

Enhancements
API Changes:
- Introduced
CallState.RINGING
- Introduced a new callback method
Call.Listener.onRinging()
. This callback is emitted once before theCall.Listener.onConnected()
callback when the callee is being alerted of aCall
. The behavior of this callback is determined by theanswerOnBridge
flag provided in theDial
verb of your TwiML application associated with this client. If theanswerOnBridge
flag isfalse
, which is the default, theCall.Listener.onConnected()
callback will be emitted immediately afterCall.Listener.onRinging()
. If theanswerOnBridge
flag istrue
, this will cause the call to emit theonConnected
callback only after the call is answered. See answeronbridge for more details on how to use it with theDial
TwiML verb. If the twiML response contains aSay
verb, then the call will emit theCall.Listener.onConnected
callback immediately afterCall.Listener.onRinging()
is raised, irrespective of the value ofanswerOnBridge
being set totrue
orfalse
