Question

我想保持没有互联网的Wifi连接，以防远程控制设备。我有一个持有WiFi锁的前台服务，而且我也尝试像这样绑定bindProcessToNetworkLooks：

val wifiManager = applicationContext
            .getSystemService(WIFI_SERVICE) as WifiManager

    if (wifiLock == null) {
        wifiLock = wifiManager.createWifiLock(WIFI_MODE_FULL_HIGH_PERF, "cameraServiceWifiLock")
    }

    Timber.d("CameraService wifiLock null=%s held=%s", wifiLock != null, wifiLock?.isHeld)
    if (wifiLock != null && !wifiLock!!.isHeld) {
        Timber.d("CameraService wifiLock acquire")
        wifiLock!!.acquire()
    }


    val cm = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
    if (SDK_INT >= M && CameraApi.network != null) {
        Timber.d("CameraService bindProcessToNetwork")
        cm.bindProcessToNetwork(CameraApi.network)
    }

现在我发现Android系统一直在随机丢弃WiFi日志：

D/WificondControl: Scan result ready event

您知道断开原因= 3是什么意思，还是我该如何告诉android这是应该立即使用的网络？

更新1：

在Linux中，

reason = 3似乎是设备无法通过DCHP解析地址。我试图在WiFi配置中设置设备的静态Ip-没有进行任何更改

Android 9断开了WiFi连接，没有互联网
