Android NSD not discovering all services

I'm trying to run an application using Android Native Service Discovery but sometimes when I run the application, it doesn't discover all services from my network. I'm running the code from https://github.com/joeluchoa/nsd using four galaxy nexus and most of the times each of them discoveries different number of services at the same time. Basically I run a service with a ServerSocket: ``` ServerSocket server = new ServerSocket(0); Log.i(TAG, "IP " + server.getInetAddress() + ", running on port " + server.getLocalPort()); Intent intent = new Intent(MySocket.this, MyPresence.class); intent.putExtra("PORT", server.getLocalPort()); startService(intent); ``` Then I publish it using the method registerService from NsdManager: ``` NsdServiceInfo serviceInfo = new NsdServiceInfo(); serviceInfo.setServiceName(Build.SERIAL + "-" + new Date().getTime()); serviceInfo.setServiceType(SERVICE_TYPE); serviceInfo.setPort(port); mNsdManager.registerService(serviceInfo, NsdManager.PROTOCOL_DNS_SD, mRegistrationListener); ``` To discover the services I use the method discoverServices from NsdManager: ``` mNsdManager.discoverServices(SERVICE_TYPE, NsdManager.PROTOCOL_DNS_SD, mDiscoveryListener); ``` With mDiscoveryListener as follows: ``` mDiscoveryListener = new NsdManager.DiscoveryListener() { @Override public void onDiscoveryStarted(String regType) { Log.d(TAG, "Service discovery started"); } @Override public void onServiceFound(NsdServiceInfo service) { Log.d(TAG, "Service discovery success"); Log.d(TAG, String.format("%s %s %s %d", service.getServiceName(), service.getServiceType(), service.getHost(), service.getPort())); if (!service.getServiceType().contains(SERVICE_TYPE)) { Log.d(TAG, "Unknown Service Type: " + service.getServiceType()); } else if (service.getServiceName().equals(mServiceName)) { Log.d(TAG, "Same machine: " + mServiceName); } else { mNsdManager.resolveService(service, mResolveListener); } } @Override public void onServiceLost(NsdServiceInfo service) { Log.e(TAG, "service lost" + service); } @Override public void onDiscoveryStopped(String serviceType) { Log.i(TAG, serviceType + " Discovery stopped: " + serviceType); } @Override public void onStartDiscoveryFailed(String serviceType, int errorCode) { Log.e(TAG, serviceType + " Discovery failed: Error code:" + errorCode); mNsdManager.stopServiceDiscovery(this); } @Override public void onStopDiscoveryFailed(String serviceType, int errorCode) { Log.e(TAG, serviceType + " Discovery failed: Error code:" + errorCode); mNsdManager.stopServiceDiscovery(this); } }; ``` Am i doing something wrong? Does anybody know a solution or a workaround for this?
