如何在Android中使用YouTube数据API搜索视频 [英] How to search videos with youtube data API in Android

问题描述

我正在用Android开发一个应用程序，该应用程序需要按关键字搜索YouTube的视频.我已将Youtube数据API与以下代码一起使用:

I'm developing an application in Android which needs to search for videos of YouTube by Keyword. I have used Youtube data API with the code below:

    try {
        youtube = new YouTube.Builder(Auth.HTTP_TRANSPORT, Auth.JSON_FACTORY, new HttpRequestInitializer() {
            public void initialize(HttpRequest request) throws IOException {
            }
        }).setApplicationName("YoutubeQoE").build();

        // Define the API request for retrieving search results.
        YouTube.Search.List search = youtube.search().list("id,snippet");

        // Set your developer key from the Google Cloud Console for
        // non-authenticated requests. See:
        // https://cloud.google.com/console
        search.setKey(DeveloperKey.DEVELOPER_KEY);
        search.setQ("dogs");

        // Restrict the search results to only include videos. See:
        // https://developers.google.com/youtube/v3/docs/search/list#type
        search.setType("video");

        // To increase efficiency, only retrieve the fields that the
        // application uses.
        //search.setFields("items(id/kind,id/videoId,snippet/title,snippet/thumbnails/default/url)");
        search.setMaxResults(25);

        SearchListResponse searchResponse = search.execute();
        List<SearchResult> lista = searchResponse.getItems();

    } catch (GoogleJsonResponseException e) {
        System.err.println("There was a service error: " + e.getDetails().getCode() + " : "
                + e.getDetails().getMessage());
    } catch (IOException e) {
        System.err.println("There was an IO error: " + e.getCause() + " : " + e.getMessage());
    } catch (Throwable t) {
        t.printStackTrace();
    }

对于DEVELOPER_KEY，我已经在Google开发人员控制台上使用了公共API访问权限.

For de DEVELOPER_KEY I have used a public API access at google developer console.

但是当我执行程序时，该行出现了问题:

But when I execute the program there is a problem in the line:

SearchListResponse searchResponse = search.execute();

SearchListResponse searchResponse = search.execute();

在android manifest.xml中，我具有以下权限:

In the android manifest.xml I have these permissions:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

如果有人能帮助我，我将不胜感激

I would be very grateful if anybody could help me
