android - 操作超时

Question

我有一个奇怪的错误:我什至设置了无限超时来尝试解决它。我说这很奇怪，因为它以前工作得很好，但现在，它不起作用，我不知道原因。错误:

这是调用 web 服务的方法:最后一行是 eclipse 告诉我问题发生的地方。

public static final String ruta = "http://10.0.0.2:2731/Api/Usuario";

        HttpParams httpParameters = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(httpParameters, 0);
        HttpConnectionParams.setSoTimeout(httpParameters, 0);
        HttpConnectionParams.setTcpNoDelay(httpParameters, true);

        HttpClient httpClient = new DefaultHttpClient(httpParameters);
        HttpGet del = new HttpGet(ruta + "s");
        del.setHeader("content-type", "application/json");

        try {
            HttpResponse resp = httpClient.execute(del);

您在代码中将超时值设置为 0。您使用大于 5000(毫秒)的值而不是 0。 即HttpConnectionParams.setConnectionTimeout(httpParameters, 5000); HttpConnectionParams.setSoTimeout(httpParameters, 5000);
