Android：Google登录无效令牌

Question

I am getting an error from the token I am receiving through google sign in android:

{ "error": "invalid_token", "error_description": "Invalid Value" }

I also noticed that my token looks a bit short compared to the one I am getting in iOS:

ya29.4AFYx2XNZ1sdfdzhWo-of-fSpsDPjgmATx-J82mCjqZJXglwj8VOvedpY_YXJgEVIWe

I am getting the token like this:

 private class RetrieveTokenTask extends AsyncTask<String, Void, String> {

        @Override
        protected String doInBackground(String... params) {
            String accountName = params[0];
            String scopes = "oauth2:profile email";
            String token = null;
            try {
                token = GoogleAuthUtil.getToken(getActivity().getApplicationContext(), accountName, scopes);
            } catch (IOException e) {
                Log.e(TAG, e.getMessage());
            } catch (UserRecoverableAuthException e) {
                //startActivityForResult(e.getIntent(), REQ_SIGN_IN_REQUIRED);
            } catch (GoogleAuthException e) {
                Log.e(TAG, e.getMessage());
            }
            return token;
        }

        @Override
        protected void onPostExecute(String token) {
            super.onPostExecute(token);
            Log.i("Token Value: ", token);
        }
}

Any idea what might be happening, or how to debug more in depth the problem?

Answer 1

Ok so I found the answer, the scopes must be written like this:

String scopes = "oauth2:"
                + Scopes.PLUS_LOGIN
                + " "
                + Scopes.PROFILE;

And the endpoint differs from android to iOS

'https://www.googleapis.com/oauth2/v1/tokeninfo?id_token='; //for iOS
'https://www.googleapis.com/oauth2/v1/tokeninfo?access_token='; //for android
