如何“分享"android应用程序在技术上可行吗? [英] How the "SHAREit" android application works technically?

问题描述

我想使用"SHAREit"之类的wi-fi在android上构建数据共享应用程序，但我没有从哪里开始.

因此，如果我对"SHAREit"的技术概念有个清晰的了解，那么理解它将会非常有效率.

1. 当我们要发送文件时，我们看到了可用接收器设备的名称.
   • 该名称显示为SSID还是其他?
   • 我们如何广播姓名和其他信息以在发送方设备上显示?
2. 当我选择要发送文件的设备时，会发生什么?
3. 实际上我可以使用的 API 是什么，请简单解释一下.

请我可以运行以测试的所有资源和链接.

解决方案

So if any clear me the technical concept of "SHAREit" it was very much efficient to understand.

   • Is the name displayed as SSID or other?
   • How we broadcast name and other info to display on sender device?
2. When I select a device to send a file then what happens?
3. What API actually I can use to and what for please explain me simply.

Please all resources and links that I could run to test.

解决方案

Use the Android Wi-Fi P2P libaries, and start with the doc on this page. It tells you how use Wi-Fi P2P for service discovery, which takes care of item 1 in your requirements. Basically, you have each device transmit a DNS-SD TXT that can contain user ID info, etc. Devices can see its contents without having to establish a socket, which is what you will later do to accomplish item 2 in your requirements.
