+/**
+ * Main ImsService implementation, which binds via the Telephony ImsResolver. Services that extend
+ * ImsService must register the service in their AndroidManifest to be detected by the framework.
+ * First, the application must declare that they use the "android.permission.BIND_IMS_SERVICE"
+ * permission. Then, the ImsService definition in the manifest must follow the following format:
+ *
+ * ...
+ * <service android:name=".EgImsService"
+ *     android:permission="android.permission.BIND_IMS_SERVICE" >
+ *     <!-- Apps must declare which features they support as metadata. The different categories are
+ *     defined below. In this example, the RCS_FEATURE feature is supported. -->
+ *     <meta-data android:name="android.telephony.ims.RCS_FEATURE" android:value="true" />
+ *     <intent-filter>
+ *         <action android:name="android.telephony.ims.ImsService" />
+ *     </intent-filter>
+ * </service>
+ * ...
+ *
+ * The telephony framework will then bind to the ImsService you have defined in your manifest
+ * if you are either:
+ * 1) Defined as the default ImsService for the device in the device overlay using
+ *    "config_ims_package".
+ * 2) Defined as a Carrier Provided ImsService in the Carrier Configuration using
+ *    {@link CarrierConfigManager#KEY_CONFIG_IMS_PACKAGE_OVERRIDE_STRING}.
+ *
+ * The features that are currently supported in an ImsService are:
+ * - RCS_FEATURE: This ImsService implements the {@link RcsFeature} class.
+ * - MMTEL_FEATURE: This ImsService implements the {@link MMTelFeature} class.
+ * - EMERGENCY_MMTEL_FEATURE: This ImsService implements the {@link MMTelFeature} class and will be
+ *   available to place emergency calls at all times. This MUST be implemented by the default
+ *   ImsService provided in the device overlay.
