Android的查找时，它的承载热点设备的IP地址

问题描述

我需要找到设备的IP地址时，它的承载热点。我用这个code到目前为止：

I need to find the device's ip address when it's hosting a hotspot. I've used this code so far :

//if is using Hotspot
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
    NetworkInterface intf = en.nextElement();
    if (intf.getName().contains("wlan")) {
        for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
            InetAddress inetAddress = enumIpAddr.nextElement();
            if (!inetAddress.isLoopbackAddress() && (inetAddress.getAddress().length == 4)) {
                return inetAddress.getHostAddress();
            }
        }
    }
}

这工作得很好，但在无线的NetworkInterface 名称不同，在某些设备上。所以，我一定要找到该设备的WiFi 的NetworkInterface 名称（其热点）第一。我如何才能找到这个名字呢？还是有更好的方法来找到设备的IP地址？

This works quite fine but the wifi NetworkInterface name differs on some devices. So I have to find the device's wifi NetworkInterface name (for its hotspot) first. How can I find this name? Or is there a better approach to find the device's ip address?

///查找的MAC正确的IP地址也似乎不工作

/// Finding the right ip address by the MAC also doesn't seem to work

推荐答案

最近我想通了，在WifiAP IP地址硬codeD的Andr​​oid系统。除非用户手动修改这个值（我认为这是非常罕见的），使用硬codeD值是绝对足够了。我认为这是最好的一段路要走。 IP地址为192.168.43.1：<一href="https://github.com/CyanogenMod/android_frameworks_base/blob/cm-10.1/wifi/java/android/net/wifi/WifiStateMachine.java?source=c#L1299">https://github.com/CyanogenMod/android_frameworks_base/blob/cm-10.1/wifi/java/android/net/wifi/WifiStateMachine.java?source=c#L1299

I recently figured out that the WifiAP ip address is hardcoded in Android. Unless a user has changed this value manually (I think that is very uncommon) using the hardcoded value is absolutely sufficient. I think this is the best way to go. The IP address is "192.168.43.1" : https://github.com/CyanogenMod/android_frameworks_base/blob/cm-10.1/wifi/java/android/net/wifi/WifiStateMachine.java?source=c#L1299
