Как внедрить фоновую службу Android в проект NativeScript Angular?

Я пытаюсь создать фоновую службу для nativescript-geolocation, чтобы получать уведомления при запуске события.

Я нашел много примеров для общей версии NS, но ничего для версии Angular, и я не могу найти способ ее реализовать.

В настоящее время я получаю Class "com.nativescript.location.BackgroundService" not found. сообщений об ошибках.

Службы были объявлены в AndroidManifest.xml, удален каталог платформ и выполнена чистая сборка.

<service android:name="com.nativescript.location.BackgroundService"
         android:exported="false" >
</service>
<service android:name="com.nativescript.location.BackgroundService26"
         android:permission="android.permission.BIND_JOB_SERVICE"
         android:enabled="true"
         android:exported="false">
</service>

Я использую это как ссылку и пытаюсь создать версию Angular этого https://github.com/NativeScript/nativescript-geolocation/tree/master/demo
