Java 如何确定设备连接到internet时使用的网络
到目前为止,我试图通过使用Java 如何确定设备连接到internet时使用的网络,java,blackberry,Java,Blackberry,到目前为止,我试图通过使用radio-info类来验证哪个网络处于打开状态,并检查radio-info.getNumberOfPacketsReceived()\Sent()中是否有任何更改,但如果有多个网络处于打开状态,这种方法是无用的。谁能给我指一下正确的方向吗 很抱歉拼写和语法错误,英语不是我的第一语言。您需要在URL后附加连接类型 public static String getConnectionString() { String connectionString = null;
radio-info

它将决定可用的网络类型。您能给出一个您想要实现的目标吗?即使启用了wifi,一些应用程序仍然可以使用radio Connection。我想采用Android应用程序,通过移动网络和wifi测量互联网流量。在Android中,我使用\TrafficStats.getMobileRxBytes\和\TrafficStats.getTotalRxBytes\。在blackberry SDK中,所有统计数据都封装在\Radio Info.getNumberOfPacketsReceived()\Sent()\中,因此现在我需要确定当其他应用程序使用internet时使用的是哪个网络。感谢您的响应和cod示例,但我不会尝试通过开放网络创建到internet的连接。我想确定其他应用程序使用internet时使用的是哪个网络。
con = (HttpConnection) Connector.open(url + getConnectionString());
