Android token - data loss on app cache clear

I have this token that I am using to call remote rest API
I get this token from the server in the app at runtime (when user install the app)
How/where can I store this token on Android device so it will not go away,
So even if user clear the app cache or clear the app data it will stay?
So local file or db is out of the question..
Thank you
