* 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">

 * 
*

* 2. Registration of {@link PhoneAccount} with {@link TelecomManager}. *
* See {@link PhoneAccount} and {@link TelecomManager#registerPhoneAccount} for more information. *

* System managed {@link ConnectionService}s must be enabled by the user in the phone app settings * before Telecom will bind to them. Self-managed {@link ConnectionService}s must be granted the * appropriate permission before Telecom will bind to them. *

* Once registered and enabled by the user in the phone app settings or granted permission, telecom * will bind to a {@link ConnectionService} implementation when it wants that * {@link ConnectionService} to place a call or the service has indicated that is has an incoming * call through {@link TelecomManager#addNewIncomingCall}. The {@link 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 {@link ConnectionService} * receives call-commands such as answer, reject, hold and disconnect. *

* When there are no more live calls, telecom will unbind from the {@link ConnectionService}. */ public abstract class ConnectionService extends Service { /** * The {@link Intent} that must be declared as handled by the service. */ @SdkConstant(SdkConstant.SdkConstantType.SERVICE_ACTION) public static final String SERVICE_INTERFACE = "android.telecom.ConnectionService"; /** * Boolean extra used by Telecom to inform a {@link ConnectionService} that the purpose of it * being asked to create a new outgoing {@link Connection} is to perform a handover of an * ongoing call on the device from another {@link PhoneAccount}/{@link ConnectionService}.
