| /** |
| * 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}. |
