Android Question Google Oauth class

[walterf25]

Hello everyone, i just came across this google Oauth class and it fits perfectly for a project i'm working on which requires to sign in to Gmail without asking the user for a password, however i have a service running which checks every 30 seconds if there are any new emails.

My questions are the following:
can i check if the accesstoken has expired from a service?
and how do i obtain a new one?
does the app have to launch the browser to ask the user for permission every time the accesstoken expires and the app needs to get a new one?

Thanks in advance for you guy's help.

Regards,
Walter

If the token is not revoked then you should get updated token automatically.

That's the issue, I'm not getting a refresh token.

Make sure to use the latest version of GoogleOAuth2 class. It is attached separately: https://www.b4x.com/android/forum/threads/class-b4x-google-oauth2.79426/#content

If implemented correctly it can run forever after the user granted permission once.
