我应该连接到 Web 服务的 Android 客户端崩溃了。我知道我在我的主线程中连接到 HTTP，但我添加了两行来解决问题（暂时）。稍后我将添加 AsyncTask。

主要活动：

protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();

        StrictMode.setThreadPolicy(policy); 

        try {
            GameAndroidUtil.testGameWS();
        } catch (SoapFault e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

我希望您在应用程序清单中添加了 Internet 权限。

<manifest xlmns:android...>
 ...
 <uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>

编辑：localhost:8080您正在尝试通过指定作为托管服务的系统的地址 来连接到 Web服务。Android 模拟器在虚拟机 (QEMU) 中运行。因此，localhost:8080将是仿真器自己的环回地址，而不是系统的环回地址。

因此，您可以在 Windows 中转到 CommandPrompt 以获取系统的 IP 地址，或者只使用http://10.0.2.2:8080/...而不是使用localhost.
