ConnectionService

public abstract class ConnectionService
extends Service

java.lang.Object
↳	android.content.Context
	↳	android.content.ContextWrapper
		↳	android.app.Service
			↳	android.telecom.ConnectionService

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.

void addConference (Conference conference)

Adds a new conference call.

void conferenceRemoteConnections (RemoteConnection remoteConnection1, 
                RemoteConnection remoteConnection2)

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`	`RemoteConnection`: The first of the remote connections to conference.
`remoteConnection2`	`RemoteConnection`: The second of the remote connections to conference.

RemoteConnection createRemoteOutgoingConnection (PhoneAccountHandle connectionManagerPhoneAccount, 
                ConnectionRequest request)

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

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

getAllConferences

Returns
`Collection<Connection>`	A collection of `Connection`s created by this `ConnectionService`.

onBind

Added in API level 23

IBinder onBind (Intent intent)

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

Added in API level 23

void onConference (Connection connection1, 
                Connection connection2)

Parameters
`connection1`	`Connection`: A connection to merge into a conference call.
`connection2`	`Connection`: A connection to merge into a conference call.

onCreateIncomingConnection

Added in API level 23

Connection onCreateIncomingConnection (PhoneAccountHandle connectionManagerPhoneAccount, 
                ConnectionRequest request)

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

onCreateOutgoingConnection

Added in API level 23

Connection onCreateOutgoingConnection (PhoneAccountHandle connectionManagerPhoneAccount, 
                ConnectionRequest request)

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

Parameters

Parameters
`connectionManagerPhoneAccount`	`PhoneAccountHandle`: 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`	`ConnectionRequest`: Details about the outgoing call.

connectionManagerPhoneAccount

PhoneAccountHandle: 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 ConnectionRequest: Details about the outgoing call.

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

onRemoteConferenceAdded

Added in API level 23

void onRemoteConferenceAdded (RemoteConference conference)

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`	`RemoteConference`: The remote conference call.

onRemoteExistingConnectionAdded

Added in API level 23

void onRemoteExistingConnectionAdded (RemoteConnection connection)

Called when an existing connection is added remotely.

Parameters
`connection`	`RemoteConnection`: The existing connection which was added.

onUnbind

Added in API level 23

boolean onUnbind (Intent intent)

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

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