AsyncTask在尝试获取令牌时触发错误消息

Question

我试着用谷歌的游戏服务来验证自己的身份，但我无法这样做。

我获得令牌的代码如下，

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

        @Override
        protected String doInBackground(String... params) {
            try {
                return fetchToken(params[0]);
            } catch (IOException e) {
                return null;
            }
        }

        @Override
        protected void onPostExecute(String result) {
            if (result != null) {
                ProximityApi.getInstance(MainActivity.this)
                        .setAuthToken(result);
                setResult(RESULT_OK);
                finish();
            }
        }
    }

我得到的错误响应如下，

Answer 1

错误是不言自明的。这一点：UserRecoverableAuthException: DeviceManagementSyncDisabled似乎是根本原因。(上述错误的解释)

我假设您需要在测试设备上启用同步，这将解决错误。

PS:日志中的以下文本是因为八月失败了。
