AsyncTask在尝试获取令牌时触发错误消息

我试图在后台获取令牌以使用google playservices进行身份验证，但我无法这样做。AsyncTask在尝试获取令牌时触发错误消息

我的代码来获得令牌如下，

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(); 
      } 
     } 
    }

错误响应，我得到的是如下，

发布完整的logcat结果 –

它是用于获取GCM的令牌。因为你错过了一些不正确的东西。可能是需要在工作线程 –

我已经发布了完整的logcat结果 –

的错误是自我解释。这：UserRecoverableAuthException: DeviceManagementSyncDisabled似乎是根本原因。（Explanation的上述错误）

我假设您需要在您的测试设备上启用同步，并且应该可以解决该错误。

PS：日志中的以下文本是因为Auth失败。
