I am using the followin code to get an Access Token, after connecting to Google+, to get profile info and e-mail:

String sAccessToken = GoogleAuthUtil.getToken(this,mPlusClient.getAccountName() + "",
                          "oauth2:" + Scopes.PLUS_PROFILE + " 
                          https://www.googleapis.com/auth/userinfo.profile 
                          https://www.googleapis.com/auth/userinfo.email");

This Access Token I am not storing and trying to re-use. Instead I ask for an Access Token everytime, expecting a new(different) Token, so that I don't need to check whether its expired etc..

But I am getting the same Access Token every time I ask for. I uninstalled the app, cleared data of Google+ App and still I get the same Access Token.

The Actual problem is, using this Access Token gives a 401 error - "message": "Invalid Credentials"

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "authError",
    "message": "Invalid Credentials",
    "locationType": "header",
    "location": "Authorization"
   }
  ],
  "code": 401,
  "message": "Invalid Credentials"
 }
}

This is a response on browser.

On a device I get this in Logcat:
