当互联网连接可用时，黑莓会收到通知。
有什么方法可以知道黑莓设备中的网络是否已连接。我有以下代码，但它一直在等待，直到网络超时。
int rc = connection.getResponseCode();
if (rc != HttpConnection.HTTP_OK) {
throw new IOException("HTTP response code: " + rc);
}
还有什么办法吗。

有几个API用于获取网络信息：

该问题的标题与问题正文的含义不同。根据标题，您可以使用RadioStatusListener 接口在网络启动时收到通知，该接口定义了一个networkStarted() 函数。然后，您可以使用 Coldice 建议的检查来确保当前网络支持数据传输。

The title of this question has a different meaning than the body of the question. Based on the title, you can be notified when the network starts by using the RadioStatusListener interface, which defines a networkStarted() function. You could then use the checks that coldice recommends to make sure that the current network supports data transfer.
