[最新]Android 热点(HotSpot) 开关检测

作者: 逆水寒Stephen | 来源:发表于2022-08-31 17:11 被阅读0次

问题背景:

需求是实时检测android手机的热点是否打开,网上百度,谷歌都是:
1).主动检测:通过反射去WifiManager类的getWifiApState方法或者isWifiApEnabled方法的值
2).被动检测:动态注册监听广播android.net.wifi.WIFI_AP_STATE_CHANGED,然后判断值是否为11(关闭)/13(打开)
此二方法可适配现在大部分新手机,但是我遇到了一台华为手机(为鸿蒙系统)主动检测一直是false,且不触发被动广播,大写的郁闷!!

问题原因:

经详细查询,这个问题是一个技术变迁导致的问题,手机wifi网卡同一时间只能处于一种状态下(连接wifi上网/做为ap提供网络);
现在比较新的手机支持双网卡,比如小米新款机型,就能实现wifi不断地情况在开ap;
而有些手机只有一张网卡,因此打开热点就只能关闭wifi,这个时候触发的广播其实是android.net.conn.TETHER_STATE_CHANGED,这个广播里面会包含当前支持ap的有那几个接口availableArray,现在激活的是哪个接口tetherArray;其中接口大概有:p2p0, wlan0, p2p-p2p0-6, wlan1, ap0等;

我通过对比三台手机监听android.net.conn.TETHER_STATE_CHANGED这个广播对比发现出问题的华为手机打开/关闭热点tetherArray有变化,因此根据这个特点对原主动检测方法做了兼容处理,完美解决问题,下面是日志记录(其中华为nova 7为问题机型,日志中的标识在最下面的代码里可查看):

解决代码(isHotSpotApOpen()和isHotSpotApOpen2()二选一即可):

//注册广播

                13 -> EventBus.getDefault().post(MsgOperationEvent(MsgOperationEvent.MsgHotSpotChangeState, 1))//已开启
            }
        } else if (action == "android.net.conn.TETHER_STATE_CHANGED") {

                    "error:$error===>isCompatCheckApOpen:${UtilsJava.isCompatCheckApOpen}")
            EventBus.getDefault().post(MsgOperationEvent(MsgOperationEvent.MsgHotSpotChangeState, if(UtilsJava.isCompatCheckApOpen) 1 else 0))
        }
      Utils.debugPrintln("======Stephen=======HotSpotStateReceiver==>"+UtilsJava.isHotSpotApOpen(context)+"/"+UtilsJava.isHotSpotApOpen2(context))
