Android:不推荐使用 WifiInfo.getIpAddress()

Question

API 31 已弃用 getIpAddress() 需要帮助从回调实现中获取地址

val networkCallback = object : ConnectivityManager.NetworkCallback() {

    override fun onAvailable(network: Network) {}


    @RequiresApi(Build.VERSION_CODES.Q)
    override fun onCapabilitiesChanged(network: Network, networkCapabilities: NetworkCapabilities) {
        super.onCapabilitiesChanged(network, networkCapabilities)
        val wifiInfo = networkCapabilities.transportInfo as? WifiInfo
    }

    override fun onLinkPropertiesChanged(network: Network, linkProperties: LinkProperties) {
        super.onLinkPropertiesChanged(network, linkProperties)
        // val ipV4Address = ?

    }
};

对于不推荐使用的方法，您可以阅读官方 android 文档，作为documnet syas:

This method was deprecated in API level 31. Use the methods on LinkProperties which can be obtained either via NetworkCallback#onLinkPropertiesChanged(Network, LinkProperties) or ConnectivityManager#getLinkProperties(Network).

所以通过我在这里添加的这种方法，你可以获得所有的IP地址:

   private fun getIpAddress() {
    val connectivityManager = getSystemService(Context.CONNECTIVITY_SERVICE)
     if (connectivityManager is ConnectivityManager) {
        var link:LinkProperties =  connectivityManager.getLinkProperties(connectivityManager.activeNetwork) as LinkProperties
         Log.e("NETWOOOOOOOOOOOORK", link.linkAddresses.toString())
    }

}

注意: link.linkAddresses 方法可能返回地址数组
