Hello,
I am try to read values from Remote Config from an Android Background Service.
Why? I want to notify the user via Android Notification if a Remote Config Value was changed (like a “news” property).
What is the best way to read Remote Config values from an Android Background Service?

Do you mean from the Unity service? There’s more info here:
https://unity.com/remote-config
Otherwise it’s just some kind of REST call, probably with UnityWebReqest to whatever “android background service” you are talking about.
Sorry, I need a solution to do this from an Android Background Service that must write in Java. I cannot access the Unity scripting solutions to do this.
If it has to be Java, I guess break out the Android docs and Android Studio… I haven’t done any Android Service stuff myself and that is far outside of the Unity context, but you can use these handy Unity classes to interoperate with Android OS from within a Unity program:
https://docs.unity3d.com/ScriptReference/AndroidJavaClass.html
That is not my point of interest. I need a solution to get the Remote Config values from Java Code. I now how to write a native Android App and a native Android Service. But I must get the Remote Config values from this service.
Sorry.
