如何获得在Android上多播数据包 [英] How to receive Multicast packets on Android

问题描述

我想从一个组播地址接收数据，但调用MulticastSocket.receive（）阻塞，直到超时发生。 我做了一些网络嗅探，并发现我的设备（和仿真器）从不发送MulticastSocket.joinGroup请求。 我想从我的电脑作为一个独立的应用程序运行在同一个Java code，效果不错。会不会是Android平台块IGMP加入请求？ 与多播前有没有人成功地在Android？

I'm trying to receive data from a multicast address, but the call to MulticastSocket.receive() blocks until a timeout takes place. I did some network sniffing and found out that my device (and the emulator) never send a MulticastSocket.joinGroup request. I tried running the same Java code from my PC as a standalone application and it worked well. Could it be that the Android platform blocks IGMP join requests? Has anyone succeeded with Multicast on Android before?

我的清单文件包含以下权限：

My manifest file contains the following permission:

我正在我的2.1的应用程序（这两个仿真器和放大器;设备）。

I am running my application on 2.1 (Both emulator & device).

任何想法吗？

谢谢

推荐答案

，因为它似乎，还有在模拟器没有适当的多播支持。

As it seems, there is no proper multicast support in the emulator.
