java - Android:从 JAVA 中的 SocketFactory 获取 DatagramSocket

Question

有没有办法从android中的SocketFactory获取DatagramSocket？

https://developer.android.com/reference/javax/net/SocketFactory.html

createSocket

added in API level 1
Socket createSocket (String host, 
                int port)

上面获取的是 TCP 类型的 Socket。需要一个 DatagramSocket UDP 套接字。

这可能吗？

用例:

https://developer.android.com/reference/android/net/Network.html#getSocketFactory()

从 Network.getSocketFactory 专门获取一个 DatagramSocket。

谢谢

Answer 1

从 API 级别 22 开始，您可以使用 Network.bindSocket(DatagramSocket)

Binds the specified DatagramSocket to this Network. All data traffic on the socket will be sent on this Network, irrespective of any process-wide network binding set by bindProcessToNetwork(Network). The socket must not be connected.
