同盾sdk获取局域网内其他设备的Ip和Mac

同盾sdk代码：

static String gqgggggg9q9qqggqq() {String str;int i = 0;try {BufferedReader bufferedReader = new BufferedReader(new FileReader("/proc/net/arp"));String str2 = "";String str3 = "";String str4 = "";String str5 = "";String str6 = "";while (true) {String readLine = bufferedReader.readLine();if (readLine == null) {str = str6;break;}try {String trim = readLine.trim();if (trim.length() >= 63 && !trim.toUpperCase(Locale.US).contains("IP")) {String trim2 = trim.substring(0, 17).trim();trim.substring(29, 32).trim();String trim3 = trim.substring(41, 63).trim();if (!trim3.contains("00:00:00:00:00:00")) {i++;str6 = str6 + trim3.replace(":", "") + trim2 + "_";if (i >= 20) {str = str6;break;}} else {continue;}}} catch (Exception e) {}}bufferedReader.close();return str.substring(0, str.length() - 1);} catch (Exception e2) {return "";}}

/proc/net/arp内容:
