/**
|
|
* 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" >
|
|
* ...
|
|
* <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_mmtel_package" or "config_ims_rcs_package".
|
|
* 2) Defined as a Carrier Provided ImsService in the Carrier Configuration using
|
|
* {@link CarrierConfigManager#KEY_CONFIG_IMS_MMTEL_PACKAGE_OVERRIDE_STRING} or
|
|
* {@link CarrierConfigManager#KEY_CONFIG_IMS_RCS_PACKAGE_OVERRIDE_STRING}.
|
|
*
|
|
* There are two ways to define to the platform which {@link ImsFeature}s this {@link ImsService}
|
|
* supports, dynamic or static definitions.
|
|
*
|
|
* In the static definition, the {@link ImsFeature}s that are supported are defined in the service
|
|
* definition of the AndroidManifest.xml file as metadata:
|
|
* <!-- Apps must declare which features they support as metadata. The different categories are
|
|
* defined below. In this example, the MMTEL_FEATURE feature is supported. -->
|
|
* <meta-data android:name="android.telephony.ims.MMTEL_FEATURE" android:value="true" />
|
|
*
|
|
* The features that are currently supported in an ImsService are:
|
|
* - RCS_FEATURE: This ImsService implements the RcsFeature class.
|
|
* - MMTEL_FEATURE: This ImsService implements the MmTelFeature class.
|
|
* - EMERGENCY_MMTEL_FEATURE: This ImsService supports Emergency Calling for MMTEL, must be
|
|
* declared along with the MMTEL_FEATURE. If this is not specified, the framework will use
|
|
* circuit switch for emergency calling.
|
|
*
|
|
* In the dynamic definition, the supported features are not specified in the service definition
|
|
* of the AndroidManifest. Instead, the framework binds to this service and calls
|
|
* {@link #querySupportedImsFeatures()}. The {@link ImsService} then returns an
|
|
* {@link ImsFeatureConfiguration}, which the framework uses to initialize the supported
|
|
* {@link ImsFeature}s. If at any time, the list of supported {@link ImsFeature}s changes,
|
|
* {@link #onUpdateSupportedImsFeatures(ImsFeatureConfiguration)} can be called to tell the
|
|
* framework of the changes.
