I've created it for my own purpose (mostly for discovering HTTP services in LAN) to simplify the whole NSD process. I also added couple of nice features (timeout, detailed log) and fixed a [#71367](https://code.google.com/p/android/issues/detail?id=71367) using simple FIFO queue. All public methods are well documented so it should be pretty straightforward to use. 7 | 8 | 9 | > **Important!** 10 | 11 | > Please note that it still under development and needs couple of tests.

There is only one listener (```NsdListener```) for all NSD actions (registration, discovery, resolve): 36 | 37 | ```java 38 | public class MainActivity extends AppCompatActivity implements NsdListener { 39 | NsdHelper nsdHelper; 40 | 41 | @Override 42 | protected void onCreate(Bundle savedInstanceState) { 43 | super.onCreate(savedInstanceState); 44 | setContentView(R.layout.activity_login); 45 | 46 | nsdHelper = new NsdHelper(this, this); 47 | nsdHelper.setLogEnabled(true); 48 | nsdHelper.setAutoResolveEnabled(true); 49 | nsdHelper.setDiscoveryTimeout(30); 50 | ... 51 | } 52 | ... 53 | } 54 | ``` 55 | Configuration methods: 56 | - ```setLogEnabled(boolean enabled)``` - enable logcat messages (default: false) 57 | - ```setAutoResolveEnabled(boolean enabled)``` - resolve service immediately after it was discovered (default: true) 58 | - ```setDiscoveryTimeout(int seconds)``` - if no new service has been discovered for a timeout interval, discovering will be stopped 59 | 60 | 61 | Dont forget about internet permissions: 62 | ```xml 63 | 64 | 65 | ``` 66 | 67 | ### Registration ### 68 | ```java 69 | nsdHelper.registerService("Chat", NsdType.HTTP); 70 | ... 71 | nsdHelper.unregisterService(); 72 | ``` 73 | ### Discovery ### 74 | ```java 75 | nsdHelper.startDiscovery(NsdType.HTTP); 76 | ... 77 | nsdHelper.stopDiscovery(); 78 | ``` 79 | ### Resolve ### 80 | ```java 81 | nsdHelper.resolveService(nsdService); 82 | ``` 83 | ### Listeners ### 84 | There is only one listener common for all actions. Implement ```NsdListener``` interface: 85 | ```java 86 | @Override 87 | public void onNsdRegistered(NsdService registeredService) { 88 | } 89 | 90 | @Override 91 | public void onNsdDiscoveryFinished() { 92 | } 93 | 94 | @Override 95 | public void onNsdServiceFound(NsdService foundService) { 96 | } 97 | 98 | @Override 99 | public void onNsdServiceResolved(NsdService resolvedService) { 100 | } 101 | 102 | @Override 103 | public void onNsdServiceLost(NsdService lostService) { 104 | } 105 | 106 | @Override 107 | public void onNsdError(String errorMessage, int errorCode, String errorSource) { 108 | } 109 | ``` 110 | 111 | ### Example logcat output ### 112 | 113 | ``` 114 | D/NsdHelper: Service discovery started. 115 | D/NsdHelper: Service found -> Kodi (OpenELEC) 116 | D/NsdHelper: Service found -> ds115 117 | D/NsdHelper: Service resolved -> Kodi (OpenELEC), OpenElec.lan/192.168.1.110, port 80, ._http._tcp 118 | D/NsdHelper: Service resolved -> ds115, DS115.lan/192.168.1.102, port 5000, ._http._tcp 119 | D/NsdHelper: Registered -> Chat 120 | D/NsdHelper: Service discovery stopped. 121 | D/NsdHelper: Unregistered -> Chat 122 | ``` 123 | 124 | 125 | ### License ### 126 | ``` 127 | Copyright 2016 Rafał Kobyłko 128 | 129 | Licensed under the Apache License, Version 2.0 (the "License"); 130 | you may not use this file except in compliance with the License. 131 | You may obtain a copy of the License at 132 | 133 | http://www.apache.org/licenses/LICENSE-2.0 134 | 135 | Unless required by applicable law or agreed to in writing, software 136 | distributed under the License is distributed on an "AS IS" BASIS, 137 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 138 | See the License for the specific language governing permissions and 139 | limitations under the License. 140 | ``` 141 | -------------------------------------------------------------------------------- /gradlew: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env bash 2 | 3 | ############################################################################## 4 | ## 5 | ## Gradle start up script for UN*X 6 | ## 7 | ############################################################################## 8 | 9 | # Add default JVM options here.
