accountmanager refresh token(offline access)

Question

I use google login through account manager in my android app. I can get accesstoken which I send to server and server can create/login new user. Accesstoken is valid only 3600seconds. Problem is that server can not update user's info after this time expires. Web app requires check user's info periodically.

How can I get authentication token and refresh token from android account manager so than server can use refresh token to update data periodically? I don't want use login through webview in android app.

Thanks

Answer 1

This is now possible: https://developers.google.com/+/mobile/android/sign-in#server-side_access_for_your_app

You request a one-time authorisation code, send it to your server and your server exchanges it for an access token and refresh token.

Answer 2

Currently you can't, which I'm sure is not the answer you're hoping for, sorry about that! If you have a web sign in, you can use the hybrid flow to get a refresh token on the server as well (see https://developers.google.com/+/web/signin/server-side-flow), but there's no way of retrieving a code as part of the Android or iOS flows.

If this is something that you need for you use case, could you file a feature request on here: https://code.google.com/p/google-plus-platform/issues - we are actively looking at the number of stars on that to gauge demand for various features.
