Secure API how to do?

Question

Android

In the application I am trying to interact with the api of the online service. The question arose, it turns out that anyone who decompiles my apk file will receive access keys and will be able to access the service from their application (can delete, add information). How to avoid it?

Answer 1

Get an API key from your server in some tricky way and store it in a secure storage (preferably in encrypted form)
