【问题描述】：

安装 XAMPP 服务器，创建数据库并成功从 chrome 浏览器和 android 模拟器访问它。但是，每当我尝试从我的三星设备运行应用程序时，它都会拒绝连接我的 IP 地址。

我的 IP 地址没有在 DNS 中注册。

我试过了： 1) 从 url- 127.0.0.1 和 localhost 访问 2) 修改 httpd.conf 和 httpd-xampp.conf 文件 - 更改为需要所有授予的权限 3）卸载我的防病毒软件 4) 更改防火墙和代理设置 5) 在防火墙高级安全中创建新的入站规则 6）重新输入INTERNET权限 7) 写了 httpPost.setHeader("Accept", "application/json");在代码中

我仍然收到以下错误：

【参考方案1】：

请尝试检查您 PC 的本地 IP 地址。将手机连接到同一网络（WIFI）。然后使用以下地址/端口连接到您的 PC。

在安卓中：

网址：your_pc_local_ip

PORT：80（但我认为这不是强制性的）

我以这种方式使用，它对我来说工作正常。

【讨论】：

谢谢布莱希。它的工作！但是，我的应用程序通过同一网络（WIFI）运行我如何通过另一个网络访问它？

不幸的是我不知道。对不起。

Blehi，还有一个问题.. 现在它说“java.net.SocketException: The operation timed out at org.apache.harmony.luni.platform.OSNetworkSystem.connectStreamWithTimeoutSocketImpl”怎么办？跨度>

我不知道到底是什么问题，不幸的是我的笔记本电脑死了，所以我不能告诉你我是如何建立连接的。我记得我尝试使用 apache 和 volley 并且它工作正常。当它得到修复时，我会更新我的答案。我希望不会太晚。

Np。它得到了修复。实际上，由于网络的变化，我的 IP 地址发生了变化。感谢您的回复布莱希。 :)
