What is the correct way to check the access_token on the Android server?

Question

Android

Hey! At the first launch and subsequent android application, you need to check the availability and relevance of the access_token.
Do I understand correctly: If it is not in the phone database, we do authorization on the server and get a token, enter it into the database.
If there is a token, we send a test request to check the token, like api.site.ru/v1/auth/check;
if it is clumsy, we proceed to the registration stage.

Answer 1

Instead of it is better to check during request something?
Those. store the token locally and send it where the token is needed, and the server already checks - the token is up-to-date - gives a normal answer, not up-to-date - gives an error and a specific code that the token is not up-to-date.
If you receive an error that the token is not relevant, you need to refresh it.
In this way you get rid of unnecessary requests
