推荐答案

您可以通过可用的网络API在Android中轻松完成此操作，但请记住，如果没有路由器和网络连接，您无法做到这一点。 ：笑：



您的应用程序将连接到网络，并寻找网络上的任何活动客户端 - 也许其他人需要将自己显示为活动状态，并为此您也可以为他们提供应用程序并启用网络可见性。之后，您可以在套接字上传输数据。例如，Android Developer网站上的这篇文档讨论了与WiFi的点对点连接; 使用Wi-Fi创建P2P连接Android开发者 [ ^ ]这正是你所需要的。

You can do this easily in Android through the Networking APIs available, but remember you cannot do this without a router and the network connection. :laugh:

Your application will connect to the network, and look for any active clients on the network — maybe others would need to show themselves as active, and for this you can provide them with the app as well and enable the network visibility. After that, you can transfer the data on the sockets. For instance, this documentation on Android Developer website talks about peer-to-peer connectivity with WiFi; Creating P2P Connections with Wi-Fi | Android Developers[^] and this is exactly what you need.

您可以使用NFC（如果足够接近）或蓝牙。无需额外的硬件。

You can use either NFC (if they are close enough) or Bluetooth for this. No additional hardware required.
