/**
|
|
* Base class for service that allows system apps to suggest phone accounts for outgoing calls.

|
|
* Phone account suggestions allow OEMs to intelligently select phone accounts based on knowledge
|
|
* about the user's past behavior, carrier billing patterns, or other factors unknown to the AOSP
|
|
* Telecom system.
|
|
* OEMs who wish to provide a phone account suggestion service on their device should implement this
|
|
* service in an app that resides in the /system/priv-app/ directory on their device. For security
|
|
* reasons, the service's entry {@code AndroidManifest.xml} file must declare the
|
|
* {@link android.Manifest.permission.BIND_PHONE_ACCOUNT_SUGGESTION_SERVICE} permission:
|
|
* <pre>
|
|
* {@code
|
|
* <service android:name="your.package.YourServiceName"
|
|
* android:permission="android.permission.BIND_PHONE_ACCOUNT_SUGGESTION_SERVICE">

* <action android:name="android.telecom.PhoneAccountSuggestionService"/>
|
|
* </intent-filter>
|
|
* </service>
|
|
* }
|
|
* </pre>
|
|
* Only one system app on each device may implement this service. If multiple system apps implement
|
|
* this service, none of them will be queried for suggestions.
