最后一天我试图修复我的 asynchttpclient 的一个错误，但是我创建的帮助并没有解决这个问题。 希望有人可以帮助我。 错误是当我启动该服务时，我希望该任务始终使用 php 执行 sql 查询并接收我稍后将使用的参数。

感谢 future 的帮助!!

最佳答案

错误“在 AsyncHttpClient 中使用同步 ResponseHandler。您应该在循环线程中创建响应处理程序或改用 SyncHttpClient。”提示问题是什么。

由于在这种情况下您想使用 AsyncHttpClient 而不是 SyncHttpClient，因此您需要使用循环线程。

Handler mainHandler = new Handler(Looper.getMainLooper());
Runnable myRunnable = new Runnable() {
           @Override
            public void run() {
                //Code that uses AsyncHttpClient in your case ConsultaCaract()
            }
        };
mainHandler.post(myRunnable);

关于java - AsyncHttpClient 错误中使用的同步 ResponseHandler，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35095931/
