I find the solution for list of devices connected in same network,and i placed the code below

Call this method in onCreate -> getClientList(true, 200);

write this method in our class

  public ArrayList<ClientScanResult> getClientList(boolean onlyReachables, int reachableTimeout) {
    BufferedReader br = null;
    ArrayList<ClientScanResult> result = null;
    try {
        result = new ArrayList<ClientScanResult>();
        br = new BufferedReader(new FileReader("/proc/net/arp"));
        String line;
        int i = 0;
        while ((line = br.readLine()) != null) {
            String[] splitted = line.split(" +");
            if ((splitted != null) && (splitted.length >= 4)) {
                String mac = splitted[3];
                if (mac.matches("..:..:..:..:..:..")) {
                    boolean isReachable = InetAddress.getByName(splitted[0]).isReachable(reachableTimeout);

                    if (!onlyReachables || isReachable) {
                        result.add(new ClientScanResult(splitted[0], splitted[3], splitted[5], isReachable));
                        i++;
                    }
                }
            }
        }
    } catch (Exception e) {
        Log.e(this.getClass().toString(), e.getMessage());
    } finally {
        try {
            br.close();
        } catch (IOException e) {
            Log.e(this.getClass().toString(), e.getMessage());
        }
    }
    return result;
}

if any clarifications, please reply a message for this post, THANKS

The file /proc/net/arp does not contain all devices connected to the same network. It is only a cache of recently connected devices. See http://stackoverflow.com/questions/16035636/how-to-get-all-ip-address-of-systems-connected-to-same-wi-fi-network-in-android — Clerenz, Jun 09 '16 at 21:16
