/**
* {@code ConnectionService} is an abstract service that should be implemented by any app which can
* make phone calls 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_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 dialer 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}.
* @hide
