我需要在2个roid器、1个电话和1个表格之间发送信息。 Im利用 Java来制造 app。 I m 看服务器,但我可以看一看何时开始。 感谢任何帮助:
P.s. 这两种装置都将使用相同的wifi连接,这样我就可以利用港口发出电文。
除了“@dilix”的明显解决办法外,你还可以使用像JGroups这样的图书馆,提供自动发现其他装置。
答案取决于这些装置的距离。 相互接触的权利? NFC。 在大约20英尺之内? Bluetooth。 在100米内? Wifi Direct是同侪无线连接。 超过这一点? 您需要一个中央服务器,因为没有承运人允许接收TCP或UNDP数据,即所有防火墙。 当然,所有较长距离的答案也将缩短距离。 但这里的不同解决办法也有不同的安全要求。

打耳“Rodid socket”,你甚至可以找到一些关于 st流的信息。
