I am trying to access users YouTube private data like subscriptions which require OAuth authentication. I have tried 2 approaches so far.
1.Using GoogleAuthUtil.getToken() method. But it's deprecated and using this function only access token can be acquired which expires after 1 hour. I have no idea how to retrieve refresh token using this method.
2.According to this article and this answer we should avoid use of getToken method because of security and UX problems. So I tried using Auth.GOOGLE_SIGN_IN_API. According to the documentation, we need to use GoogleSignInOptions. So I used it and using requestScopes() i added the Youtube scope. Also I used requestserverauthcode() to get the exchange code, using which access and refresh token can be acquired. Now here's my problem, we need to use GoogleApiClient with addApi(). The available set of API's doesn't have a Youtube API listed to put it in addApi(). So there is no way I can get access to access tokens / refresh token.
Can anyone help me out?
EDIT:
I solved it. I used getToken approach to get tokens. Whenever a 401 authorization error occurs, we need to call getToken method returns a new token.
