尝试打开与 http URL 的连接时出现 IOException

Question

我正在尝试使用 Connector.open("http://someurl.something/something"); 打开 HttpConnection

这在 8800 over Edge (GSM) 和 Pearl 上运行良好，但不行9800，我得到 IOException 字符串“未指定 apn”。

9800 目前没有 SIM 卡，但有可用的 WiFi 连接，我可以用它浏览网页。

有什么建议吗？

更新： 奇怪的是，如果我在 URL 中加上 ";interface=wifi" 后缀，连接实际上可以工作，但我认为它无法在 EDGE 连接上工作。这真的是正常的黑莓编程吗？您应该提前知道您想要使用哪个连接来上网？

Answer 1

仅当设备有 wifi 并且已连接时才添加 ";interface=wifi"：

if ((WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED)
                    && RadioInfo.areWAFsSupported(RadioInfo.WAF_WLAN)) {
                url += ";interface=wifi";
            }
