The sample runs successfully. But Alternatively, you should get the access token on the server side, and supply client app with it.
I set up a server and create RESTful api for app to get the access token.
{"token":"1234567890sdertyuikjhgfghjk....."}
And also use api: https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={token} to get the token info:
{ "issued_to": "102073270616313859663", "audience": "102073270616313859663", "scope": "https://www.googleapis.com/auth/cloud-platform", "expires_in": 3600, "access_type": "offline" }
Then create a Token instance:
AccessToken token = new AccessToken(tokenValue, expiresIn);
But following error:

I could use the sample code:
final InputStream stream = getResources().openRawResource(R.raw.credential);
final GoogleCredentials credentials =
GoogleCredentials.fromStream(stream).createScoped(SCOPE);
final AccessToken token = credentials.refreshAccessToken();
and get a working Token, and get its token value by using getTokenValue() and get it expiration time by getExpirationTime. Then create a Token instance:
AccessToken token = new AccessToken(tokenValue, expiresIn);
to return a AccessToken instance.
It will cause the same error. So my question is that how to create an working AccessToken instance when I get the token value string and the expiration time.
