Below is my code to discover all the available _http._tcp services. final NsdManager.DiscoveryListener discoveryListener = new NsdManager.DiscoveryListener() { @Override public void onDiscoveryStarted(String s) { Log.i(TAG, "onDiscoveryStarted: " + s); } @Override public void onServiceFound(NsdServiceInfo nsdServiceInfo) { Log.i(TAG, "onServiceFound: " + nsdServiceInfo.toString()); } @Override public void onServiceLost(NsdServiceInfo nsdServiceInfo) { Log.i(TAG, "onServiceLost: " + nsdServiceInfo.toString()

In the course of the last weeks, Android's NSD implementation is making me go mad: From a user's point of view, the following problems arise: Devices discover each other in a completely non-deterministic fashion. If I launch my NsdManager -based app, it works more or less if only two devices are involved. If a third device joins, it will seldomly discover the first two , and the first two will not see the third. If I exit the apps (they gracefully unregister the NSD listeners) and restart them in a different order, the discovery pattern is not exactly the same, but similar. In my home network,

Hi i am trying to find all devices connected to My WIFI Router from android and ,i need to device Mac address and local ip address of each device (Including iOT Devices) , right now , i am trying to find from ARP cache table . but sometime in the scan some devices are missing , it is not so accurate . My Code : List<LocalDeviceInfo> devicesInfos = new ArrayList<>(); BufferedReader bufferedReader = null; try { bufferedReader = new BufferedReader(new FileReader("/proc/net/arp")); String line; while ((line = bufferedReader.readLine()) != null) { String[] splitted = line.split(" +"); if (splitted
