/**
* An abstract service that should be implemented by any apps which either:
* <ol>
* <li>Can make phone calls (VoIP or otherwise) and want those calls to be integrated into the
* built-in phone app. Referred to as a <b>system managed</b> {@link ConnectionService}.</li>
* <li>Are a standalone calling app and don't want their calls to be integrated into the
* built-in phone app. Referred to as a <b>self managed</b> {@link ConnectionService}.</li>
* </ol>
* Once implemented, the {@link ConnectionService} needs to take the following steps so that Telecom
* will bind to it:
* <p>
* 1. <i>Registration in AndroidManifest.xml</i>
* <br/>
* <pre>
* &lt;service android:name="com.example.package.MyConnectionService"
* android:label="@string/some_label_for_my_connection_service"
* android:permission="android.permission.BIND_TELECOM_CONNECTION_SERVICE"&gt;
* &lt;intent-filter&gt;
* &lt;action android:name="android.telecom.ConnectionService" /&gt;
* &lt;/intent-filter&gt;
* &lt;/service&gt;
* </pre>
* <p>
* 2. <i> Registration of {@link PhoneAccount} with {@link TelecomManager}.</i>
* <br/>
* See {@link PhoneAccount} and {@link TelecomManager#registerPhoneAccount} for more information.
* <p>
* System managed {@link ConnectionService}s must be enabled by the user in the phone app settings
* before Telecom will bind to them. Self-manged {@link ConnectionService}s must be granted the
* appropriate permission before Telecom will bind to them.
* <p>
* 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.
* <p>
* When there are no more live calls, telecom will unbind from the {@link ConnectionService}.
