andorid跳过系统API获取以太网IP，网关，DNS，MAC的方法

最近在android平台上构建出windows的效果，之前通过EthernetManager和EthernetDevInfo获取以太网相关信息，但为了边敲代码边运行，想要跳过系统层的api调用，方法如下：

获取DNS：

private String getLocalDNS(){          Process cmdProcess = null;          BufferedReader reader = null;          String dnsIP = "";          try {              cmdProcess = Runtime.getRuntime().exec("getprop dhcp.eth0.dns1");              reader = new BufferedReader(new InputStreamReader(cmdProcess.getInputStream()));              dnsIP = reader.readLine();              return dnsIP;          } catch (IOException e) {              return null;          } finally{          try {             reader.close();              } catch (IOException e) {                 }                cmdProcess.destroy();              }    }

获取网关：

private String getLocalGATE(){        Process cmdProcess = null;        BufferedReader reader = null;        String dnsIP = "";        try {            cmdProcess = Runtime.getRuntime().exec("getprop dhcp.eth0.gateway");            reader = new BufferedReader(new InputStreamReader(cmdProcess.getInputStream()));            dnsIP = reader.readLine();            return dnsIP;        } catch (IOException e) {            return null;        } finally{            try {                reader.close();          } catch (IOException e) {             }            cmdProcess.destroy();          }    }

获取ip地址：

private String getLocalGATE(){        Process cmdProcess = null;        BufferedReader reader = null;        String dnsIP = "";        try {            cmdProcess = Runtime.getRuntime().exec("getprop dhcp.eth0.ipaddress");            reader = new BufferedReader(new InputStreamReader(cmdProcess.getInputStream()));            dnsIP = reader.readLine();            return dnsIP;        } catch (IOException e) {            return null;        } finally{            try {                reader.close();          } catch (IOException e) {             }            cmdProcess.destroy();          }    }

上面的方法只有使用的指令不一样，追求代码简洁的朋友可以合成一个方法来写，或者写入工具类中。

其他相关指令：
