调用Linux的busybox，通过linux命令来获取AndRoidIP

IT知识Linux命令

古人已用三冬足，年少今开万卷余。这篇文章主要讲述调用Linux的busybox，通过linux命令来获取AndRoidIP相关的知识，希望能为你提供帮助。
【调用Linux的busybox，通过linux命令来获取AndRoidIP】//根据busybox获取本地Mac
public static String getLocalMacAddressFromBusybox(){
String result = "";
String Mac = "";
result = callCmd("busybox ifconfig","HWaddr");

//如果返回的result == null，则说明网络不可取
if(result==null){
return "网络出错，请检查网络";
}

//对该行数据进行解析
//例如：eth0Link encap:EthernetHWaddr 00:16:E8:3E:DF:67
if(result.length()> 0 & & result.contains("HWaddr")==true){
Mac = result.substring(result.indexOf("HWaddr")+6, result.length()-1);
Log.i("test","Mac:"+Mac+" Mac.length: "+Mac.length());

/*if(Mac.length()> 1){
Mac = Mac.replaceAll(" ", "");
result = "";
String[] tmp = Mac.split(":");
for(int i = 0; i< tmp.length; ++i){
result +=tmp[i];
}
}*/
result = Mac;
Log.i("test",result+" result.length: "+result.length());
}
return result;
}

private static String callCmd(String cmd,String filter) {
String result = "";
String line = "";
try {
Process proc = Runtime.getRuntime().exec(cmd);
InputStreamReader is = new InputStreamReader(proc.getInputStream());
BufferedReader br = new BufferedReader (is);

//执行命令cmd，只取结果中含有filter的这一行
while ((line = br.readLine ()) != null & & line.contains(filter)== false) {
//result += line;
Log.i("test","line: "+line);
}

result = line;
Log.i("test","result: "+result);
}
catch(Exception e) {
e.printStackTrace();
}
return result;
}
