Question

我开发了一个应用程序，它将使用https将数据发布到服务器。代码在设备上运行良好，现在我突然得到 java.net.SocketException：操作在少数设备中超时。

以下是我的代码。

public void connectMe() {
    httpClient = new DefaultHttpClient();
    HttpConnectionParams
            .setConnectionTimeout(httpClient.getParams(), 25000);
    HttpConnectionParams.setSoTimeout(httpClient.getParams(), 25000);
    try {
        HttpResponse response = null;
        switch (method) {
        case GET:
            response = httpClient.execute(new HttpGet(url));
            break;
        case POST:
            try {
                HttpPost httpPost = new HttpPost(url);
                UrlEncodedFormEntity p_entity = new UrlEncodedFormEntity(
                        params, HTTP.UTF_8);
                httpPost.setEntity(p_entity);

                response = httpClient.execute(httpPost);

            } catch (Exception e) {
                e.printStackTrace();
            }
            break;
            }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

以下是logcat信息

我卸载并重新安装了应用程序，没有工作得到相同的异常。但在进行工厂数据重置后，上面的代码可以在同一个移动和同一网络中工作。

任何人都可以请我解释一下发生了什么......？我很困惑..

感谢。

这看起来像是临时网络问题。您也可以尝试进入飞行模式并恢复正常再次测试。
