Frequency of saving credentials

Question

I notice the Java SDK Android example only seems to save the "credential" (access token and refresh token) when it is initially created. Is there a recommended frequency for updating the credential in preferences or is that not necessary as long as the original refresh token is still valid?

As long as the refresh token is valid, it's not necessary to update the credentials. The SDK will automatically perform a refresh using the existing refresh token whenever needed.
