fix index out of bound exception when statuscode equal to SC_NO_CONTENT

if obj[] length isn't equal 3, the follow code will throw exception:

```
 @Override
    protected void handleMessage(Message msg) {
        switch(msg.what){
            case SUCCESS_JSON_MESSAGE:
                Object[] response = (Object[]) msg.obj;
                handleSuccessJsonMessage(((Integer) response[0]).intValue(),(Header[]) response[1] ,response[2]);
                break;
            default:
                super.handleMessage(msg);
        }
    }
```
