|  | * 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 {@code ConnectionService} needs two additional steps before it will be | 
|  | * integrated into the phone app: | 
|  | * <p> | 
|  | * 1. <i>Registration in AndroidManifest.xml</i> | 
|  | * <br/> | 
|  | * <pre> | 
|  | * <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> | 
|  | * </pre> | 
|  | * <p> | 
|  | * 2. <i> Registration of {@link PhoneAccount} with {@link TelecomManager}.</i> | 
|  | * <br/> | 
|  | * See {@link PhoneAccount} and {@link TelecomManager#registerPhoneAccount} for more information. | 
|  | * <p> | 
|  | * Once registered and enabled by the user in the phone app settings, telecom will bind to a | 
|  | * {@code ConnectionService} implementation when it wants that {@code ConnectionService} to place | 
|  | * a call or the service has indicated that is has an incoming call through | 
|  | * {@link TelecomManager#addNewIncomingCall}. The {@code ConnectionService} can then expect a call | 
|  | * to {@link #onCreateIncomingConnection} or {@link #onCreateOutgoingConnection} wherein it | 
|  | * should provide a new instance of a {@link Connection} object.  It is through this | 
|  | * {@link Connection} object that telecom receives state updates and the {@code ConnectionService} | 
|  | * receives call-commands such as answer, reject, hold and disconnect. | 
|  | * <p> | 
|  | * When there are no more live calls, telecom will unbind from the {@code ConnectionService}. |
