public class MainActivity extends Activity {
    TextView tv;
    String scope="audience:server:client_id:CLIENTID OF WEBPAGE";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv =(TextView)findViewById(R.id.printId);
    new AsyncTask<Void, Void, Void>() {

        @Override
        protected void onPostExecute(Void result) {
            // TODO Auto-generated method stub
            tv.setText(id);
            super.onPostExecute(result);
        }

        @Override

            // TODO Auto-generated method stub

                String[] account=getAccountNames();
                for(int i =0;i<account.length;i++)
                {
                    try {
                    Log.e("account name", account[i]);
                     id=GoogleAuthUtil.getToken(MainActivity.this, account[i], scope);
                        Log.e("google id",id);
                    } catch (UserRecoverableAuthException e) {

                        e.printStackTrace();
                    } catch (GoogleAuthException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }



            return null;
        }
    }.execute(null,null,null);


    }
    private String[] getAccountNames() {
      AccountManager  mAccountManager = AccountManager.get(this);
        Account[] accounts = mAccountManager.getAccountsByType(
                GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE);
        String[] names = new String[accounts.length];
        for (int i = 0; i < names.length; i++) {
            names[i] = accounts[i].name;
        }
        return names;
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

Answer 1

Use this code to get the scope

String scope = "oauth2:" + Scopes.PROFILE;

and use this scpe here

id=GoogleAuthUtil.getToken(MainActivity.this, account[i], scope);

Then you can get your access tocken in variable "id".Simple method.
