			↳	android.telecom.ConnectionService

Class Overview

An abstract service that should be implemented by any apps which can make phone calls (VoIP or otherwise) and want those calls to be integrated into the built-in phone app. Once implemented, the ConnectionService needs two additional steps before it will be integrated into the phone app:

1. Registration in AndroidManifest.xml

 <service android:name="com.example.package.MyConnectionService"
    android:label="@string/some_label_for_my_connection_service"
    android:permission="android.permission.BIND_TELECOM_CONNECTION_SERVICE">
  <intent-filter>
   <action android:name="android.telecom.ConnectionService" />
  </intent-filter>
 </service>

2. Registration of PhoneAccount with TelecomManager.
See PhoneAccount and registerPhoneAccount(PhoneAccount) for more information.

Once registered and enabled by the user in the phone app settings, telecom will bind to a ConnectionService implementation when it wants that ConnectionService to place a call or the service has indicated that is has an incoming call through addNewIncomingCall(PhoneAccountHandle, Bundle). The ConnectionService can then expect a call to onCreateIncomingConnection(PhoneAccountHandle, ConnectionRequest) or onCreateOutgoingConnection(PhoneAccountHandle, ConnectionRequest) wherein it should provide a new instance of a Connection object. It is through this Connection object that telecom receives state updates and the ConnectionService receives call-commands such as answer, reject, hold and disconnect.

When there are no more live calls, telecom will unbind from the ConnectionService.

Public Methods

public final void addConference (Conference conference)

Added in API level 23

Adds a new conference call. When a conference call is created either as a result of an explicit request via onConference(Connection, Connection) or otherwise, the connection service should supply an instance of Conference by invoking this method. A conference call provided by this method will persist until destroy() is invoked on the conference instance.

Parameters

conference	The new conference object.

public final void addExistingConnection (PhoneAccountHandle phoneAccountHandle, Connection connection)

Added in API level 23

Adds a connection created by the ConnectionService and informs telecom of the new connection.

Parameters

phoneAccountHandle	The phone account handle for the connection.
connection	The connection to add.

public final void conferenceRemoteConnections (RemoteConnection remoteConnection1, RemoteConnection remoteConnection2)

Added in API level 23

Indicates to the relevant RemoteConnectionService that the specified RemoteConnections should be merged into a conference call.

If the conference request is successful, the method onRemoteConferenceAdded(RemoteConference) will be invoked.

Parameters

remoteConnection1	The first of the remote connections to conference.
remoteConnection2	The second of the remote connections to conference.

public final RemoteConnection createRemoteIncomingConnection (PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request)

Added in API level 23

Ask some other ConnectionService to create a RemoteConnection given an incoming request. This is used by ConnectionServices that are registered with CAPABILITY_CONNECTION_MANAGER and want to be able to manage SIM-based incoming calls.

Parameters

connectionManagerPhoneAccount	See description at `onCreateOutgoingConnection(PhoneAccountHandle, ConnectionRequest)`.
request	Details about the incoming call.

Returns

The Connection object to satisfy this call, or null to not handle the call.

public final RemoteConnection createRemoteOutgoingConnection (PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request)

Added in API level 23

Ask some other ConnectionService to create a RemoteConnection given an outgoing request. This is used by ConnectionServices that are registered with CAPABILITY_CONNECTION_MANAGER and want to be able to use the SIM-based ConnectionService to place its outgoing calls.

Parameters

connectionManagerPhoneAccount	See description at `onCreateOutgoingConnection(PhoneAccountHandle, ConnectionRequest)`.
request	Details about the incoming call.

Returns

The Connection object to satisfy this call, or null to not handle the call.

public final Collection<Connection> getAllConnections ()

Added in API level 23

Returns all the active Connections for which this ConnectionService has taken responsibility.

Returns

A collection of Connections created by this ConnectionService.

public final IBinder onBind (Intent intent)

Added in API level 23

Return the communication channel to the service. May return null if clients can not bind to the service. The returned IBinder is usually for a complex interface that has been described using aidl.

Note that unlike other application components, calls on to the IBinder interface returned here may not happen on the main thread of the process. More information about the main thread can be found in Processes and Threads.

Parameters

intent	The Intent that was used to bind to this service, as given to `Context.bindService`. Note that any extras that were included with the Intent at that point will not be seen here.

Returns

Return an IBinder through which clients can call on to the service.

public void onConference (Connection connection1, Connection connection2)

Added in API level 23

Conference two specified connections. Invoked when the user has made a request to merge the specified connections into a conference call. In response, the connection service should create an instance of Conference and pass it into addConference(Conference).

Parameters

connection1	A connection to merge into a conference call.
connection2	A connection to merge into a conference call.

public Connection onCreateIncomingConnection (PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request)

Added in API level 23

Create a Connection given an incoming request. This is used to attach to existing incoming calls.

Parameters

connectionManagerPhoneAccount	See description at `onCreateOutgoingConnection(PhoneAccountHandle, ConnectionRequest)`.
request	Details about the incoming call.

Returns

The Connection object to satisfy this call, or null to not handle the call.

public Connection onCreateOutgoingConnection (PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request)

Added in API level 23

Create a Connection given an outgoing request. This is used to initiate new outgoing calls.

Parameters

connectionManagerPhoneAccount

connectionManagerPhoneAccount	The connection manager account to use for managing this call. If this parameter is not `null`, it means that this `ConnectionService` has registered one or more `PhoneAccount`s having `CAPABILITY_CONNECTION_MANAGER`. This parameter will contain one of these `PhoneAccount`s, while the `request` will contain another (usually but not always distinct) `PhoneAccount` to be used for actually making the connection. If this parameter is `null`, it means that this `ConnectionService` is being asked to make a direct connection. The `getAccountHandle()` of parameter `request` will be a `PhoneAccount` registered by this `ConnectionService` to use for making the connection.
request	Details about the outgoing call.

The connection manager account to use for managing this call.

If this parameter is not null, it means that this ConnectionService has registered one or more PhoneAccounts having CAPABILITY_CONNECTION_MANAGER. This parameter will contain one of these PhoneAccounts, while the request will contain another (usually but not always distinct) PhoneAccount to be used for actually making the connection.

If this parameter is null, it means that this ConnectionService is being asked to make a direct connection. The getAccountHandle() of parameter request will be a PhoneAccount registered by this ConnectionService to use for making the connection.

request Details about the outgoing call.

Returns

The Connection object to satisfy this call, or the result of an invocation of createFailedConnection(DisconnectCause) to not handle the call.

public void onRemoteConferenceAdded (RemoteConference conference)

Added in API level 23

Indicates that a remote conference has been created for existing RemoteConnections. When this method is invoked, this ConnectionService should create its own representation of the conference call and send it to telecom using addConference(Conference).

This is only relevant to ConnectionServices which are registered with CAPABILITY_CONNECTION_MANAGER.

Parameters

conference	The remote conference call.

public void onRemoteExistingConnectionAdded (RemoteConnection connection)

Added in API level 23

Called when an existing connection is added remotely.

Parameters

connection	The existing connection which was added.

public boolean onUnbind (Intent intent)

Added in API level 23

Called when all clients have disconnected from a particular interface published by the service. The default implementation does nothing and returns false.

Parameters

intent	The Intent that was used to bind to this service, as given to `Context.bindService`. Note that any extras that were included with the Intent at that point will not be seen here.

Returns

Return true if you would like to have the service's onRebind(Intent) method later called when new clients bind to it.
