推荐答案

Wi-Fi对等(P2P)允许具有适当硬件的Android 4.0(API级别14)或更高版本的设备通过彼此直接连接没有中间访问点的Wi-Fi(Android的Wi-Fi P2P框架符合Wi-Fi联盟的Wi-Fi Direct™认证计划).使用这些API，您可以在每台设备都支持Wi-Fi P2P时发现并连接到其他设备，然后通过快速连接进行通信，通信距离远超过蓝牙连接.这对于多用户游戏或照片共享应用程序之类的在用户之间共享数据的应用程序很有用

Wi-Fi peer-to-peer (P2P) allows Android 4.0 (API level 14) or later devices with the appropriate hardware to connect directly to each other via Wi-Fi without an intermediate access point (Android's Wi-Fi P2P framework complies with the Wi-Fi Alliance's Wi-Fi Direct™ certification program). Using these APIs, you can discover and connect to other devices when each device supports Wi-Fi P2P, then communicate over a speedy connection across distances much longer than a Bluetooth connection. This is useful for applications that share data among users, such as a multiplayer game or a photo sharing application
