列出作为WiFi接入点连接到Android手机的设备
当安卓手机充当WiFi路由器时,安卓API中是否有列出已连接设备的方法列出作为WiFi接入点连接到Android手机的设备,android,wifi,router,device,access-point,Android,Wifi,Router,Device,Access Point,当安卓手机充当WiFi路由器时,安卓API中是否有列出已连接设备的方法 还有一种方法可以与路由请求交互以提供欢迎/登录页面吗?这是另一个stackoverflow问题的答案,我在两个月前阅读了它,不知道答案来自哪个用户,但这应该有效。WifiManager为您提供您所需的: Main.java import java.util.ArrayList; import android.app.Activity; import android.os.Bundle; import android.widg

我认为这不是关于Android手机充当WiFi路由器,而是只是扫描Android手机范围内的接入点。我的意思是,当您可以在手机内启动wifi路由器,而其他设备(如计算机)将手机视为路由器时,请检查此链接@killer\u PL您不应“编辑”您接受的答案。如果不是你想要的答案,不要接受。如果你找到了问题的答案,请将其作为其他答案或评论分享。但是1。塞吉找到了。2.目前被接受的答案是完全离题的,任何进入该页面的人都会感到困惑。我编辑它是因为真正的答案只存在于Segi注释中,而答案内容现在(在我的编辑还原后)已脱离主题且无效。@killer\u PL在这种情况下,您实际上可以“不接受”答案,但由于Segi编辑了他的答案,所以现在与此无关。
