Android 上的 Ifconfig 和路由命令

Question

我想知道是否存在以编程方式在 Android 设备中获取 ifconfig 和 route 命令结果的方法？我可以在非 root 设备上执行此操作吗？

Answer 1

在你的AndroidManifest.xml文件中

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

您的代码：

    ConnectivityManager connectivityManager = (ConnectivityManager) getApplicationContext().getSystemService(Service.CONNECTIVITY_SERVICE);

                /* you can print your active network via using below */
                Log.i("myNetworkType: ", connectivityManager.getActiveNetworkInfo().getTypeName());
                WifiManager wifiManager= (WifiManager) getApplicationContext().getSystemService(getApplicationContext().WIFI_SERVICE);


                Log.i("routes ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getRoutes().toString());
                Log.i("domains ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getDomains().toString());
                Log.i("ip address ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getLinkAddresses().toString());
                Log.i("dns address ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getDnsServers().toString());



                if(connectivityManager.getActiveNetworkInfo().getType() == ConnectivityManager.TYPE_WIFI) {
                    Log.i("myType ", "wifi");
                    DhcpInfo d =wifiManager.getDhcpInfo();
                    Log.i("info", d.toString()+"");
                }
                else if(connectivityManager.getActiveNetworkInfo().getType() == ConnectivityManager.TYPE_ETHERNET) {
/* there is no EthernetManager class, there is only WifiManager. so, I used this below trick to get my IP range, dns, gateway address etc */

                    Log.i("myType ", "Ethernet");
                    Log.i("routes ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getRoutes().toString());
                    Log.i("domains ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getDomains().toString());
                    Log.i("ip address ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getLinkAddresses().toString());
                    Log.i("dns address ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getDnsServers().toString());

                }
                else {

                }

输出

您无法知道您是通过 wifi 连接还是使用 WifiManager 网络连接，因为 WifiManager 仅处理 wifi。你必须使用 ConnectivityManager。我再次更新了代码，合并了 WifiManager 和 ConnectivityManager 以产生您想要的结果。
