我正在尝试使用以下内容获取在我的YouTube频道上传的视频列表

https://www.googleapis.com/youtube/v3/search?part=snippet&channelId {MY_CHANNEL_ID}&maxResults = 50&key = {MY_APP_ID}

我在Google App Console中创建了应用程序并为其生成了APP ID.但是,当我尝试通过我的Android应用程序访问它时,得到java.io.FileNotFoundException错误

我也给了应用程序标识符和SHA1,如果我尝试通过Web浏览器键访问而没有任何其他约束它运行良好并返回所有视频列表但是在Android的情况下它不起作用.

@Override
    protected String doInBackground(Void... voids) {

        HttpURLConnection urlConnection = null;

        String urlString = "https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=UCrF362wkcVnjqqPRsSEzvgg&maxResults=50&key=AIzaSyAiAFjZb1eVdRxVWnymrhuAb1iDlmYupu8";

        String jsonString = new String();

        URL url = null;
        try {
            url = new URL(urlString);

        urlConnection = (HttpURLConnection) url.openConnection();

        urlConnection.setRequestMethod("GET");
        urlConnection.setReadTimeout(10000 /* milliseconds */);
        urlConnection.setConnectTimeout(15000 /* milliseconds */);

        urlConnection.setDoOutput(true);

        urlConnection.connect();

        BufferedReader br=new BufferedReader(new InputStreamReader(url.openStream()));

        char[] buffer = new char[1024];

        StringBuilder sb = new StringBuilder();
        String line;
        while ((line = br.readLine()) != …
