Answer 1

If you just want to test if the user is logged in to the device, it is sufficient to do this with SharedPreference as others indicated.

However, if you want to ensure that the user is logged in to your external website, it is more complicated and requires more work.

1- Your website should have remember me functionality by setting some cookie

2- Once the user logged in successfully to your website from the app; you need to preserve the remember me cookie (e.g. serialize it to some file)

3- When the user open the app, you have to load that cookie if exists and make a request to the server to ensure if the user still logged in or not (e.g. handle the HTTP response code)
