copied!<p>The most common way to do it is using the Youtube data API, which will return XML/Json that you can parse to retrieve things like the video url.</p> <p><strong>Updated (2017/01/24) (v3)</strong></p> <p>Use the following call to search for YouTube videos using a search query:</p> <pre><code>https://www.googleapis.com/youtube/v3/search?part=snippet&q=fun%20video&key=YOUR-API-KEY </code></pre> <p>It supports the following basic parameters for searching:</p> <ul> <li><strong>part</strong> : Video data you want to retrieve in the search. For basic searches the recommended value is <strong>snippet</strong>.</li> <li><strong>q</strong> : The text you want to search for</li> <li><strong>key</strong> : Your Google Developer API Key. This key can be obtained at the <a href="https://console.developers.google.com/" rel="nofollow noreferrer">Google Developer API Console</a> on the Credentials page of your application. Make sure to enable the Youtube Data API v3 on the application your key belongs to.</li> </ul> <p>For more parameters see the <a href="https://developers.google.com/youtube/v3/docs/search/list" rel="nofollow noreferrer">Google API Documentation</a></p> <p><strong>Using the Java library</strong></p> <p>On Android you can either do a HTTP request to the URL using the standard HTTP request classes available on the platform, or you can use the <a href="https://developers.google.com/api-client-library/java/" rel="nofollow noreferrer">Google API Java Library</a> as shown below:</p> <pre><code> YouTube youtube = new YouTube.Builder(Auth.HTTP_TRANSPORT, Auth.JSON_FACTORY, new HttpRequestInitializer() { public void initialize(HttpRequest request) throws IOException { } }).setApplicationName("YOUR-APPLICATION-NAME").build(); String queryTerm = "A fun video" // Define the API request for retrieving search results. YouTube.Search.List search = youtube.search().list("id,snippet"); search.setKey("Your-Api-Key"); search.setQ(queryTerm); // Call the API and print first result. SearchListResponse searchResponse = search.execute(); if(searchResponse.getItems().size() == 0) { //No items found. return; } SearchResult firstItem = searchResponse.getItems().get(0); ResourceId rId = firstItem.getId(); // Confirm that the result represents a video. Otherwise, the // item will not contain a video ID. if (rId.getKind().equals("youtube#video")) { Thumbnail thumbnail = firstItem.getSnippet().getThumbnails().getDefault(); Log.d("YOUTUBE_SAMPLE","Video Id" + rId.getVideoId()); Log.d("YOUTUBE_SAMPLE","Title: " + firstItem.getSnippet().getTitle()); Log.d("YOUTUBE_SAMPLE","Thumbnail: " + thumbnail.getUrl()); } </code></pre>
