How and is it possible to use vk anroid sdk together with a service key?

Question

Android

I want to work with vk api without authorization, use a service key. But here it is written that it "cannot be transferred and stored on the client". Did I understand correctly that the key cannot be stored in resources or string project variable? Can hackers open apk and get the key? If yes, what are the consequences? Can I get an insult to the feelings of someone by contacting api on my behalf? Is it necessary to make a shim between the client and the api and store the key there, or is it possible to somehow encrypt the key in the project?
If this is all nonsense, then how to transfer the service key to vk android sdk and use it without registration

Answer 1

First, the VK API rejects requests through the SDK if the application's signature fingerprint is not registered.
Secondly, almost nothing can be done with the service key, there is a search available and a few more methods.
