I just want to develop a app to ping all the devices of my house connected on wifi

This is not from android (at least I didn't tested on it), but it worked to ping my android device from my laptop (Notice device must be unlocked as in awake):

public boolean isOnline() {
  Runtime runtime = Runtime.getRuntime();
  try {
    Process ipProcess = runtime.exec("ping  xxx.xxx.xxx.xxx");
    int     exitValue = ipProcess.waitFor();
    return (exitValue == 0);
  } 
  catch (IOException e) { 
    e.printStackTrace();
  }
  catch (InterruptedException e) { 
    e.printStackTrace();
  }return false;
}

This is from reference: https://stackoverflow.com/questions/3584210/preferred-java-way-to-ping-an-http-url-for-availability

One link that could help:

From what I read, not all devices could be configured to respond to pings. I found this app might do what you want. I suggest you use it and see if it can see all the devices that you are looking for. If it does, great, then continue searching for the code:
