Creating a playlist with Youtube DATA API on Android

I am trying to use the Youtube GDATA API in order to add a new playlist to a youtube account. I base my code on the documentation: https://developers.google.com/youtube/2.0/developers_guide_protocol_playlists#Adding_a_playlist

I first get an access token and use my developer key appropriately. The post seems to work just fine, but when trying to get back the response, I get a file not found exception while calling getInputStream.

Does anyone has an idea? Thanks

Here is the connection code (an updated cleaner version):

@Override
protected Boolean doInBackground(Void... arg0) {
    BufferedReader input = null;
    InputStreamReader inputStreamReader = null;
    StringBuilder postContentXml = new StringBuilder();

    postContentXml.append("<?xml version='1.0' encoding='UTF-8'?>").
        append("<entry xmlns='http://www.w3.org/2005/Atom'") .
        append(" xmlns:yt='http://gdata.youtube.com/schemas/2007'>").
        append("<title type='text'>Sports Highlights Playlist</title>").
        append("<summary>A selection of sports highlights</summary>").
        append("</entry>");

    byte[] buffer = postContentXml.toString().getBytes();
    StringBuilder response = new StringBuilder();

    try {
        URL url = new URL("https://gdata.youtube.com/feeds/api/users/default/playlists");
        HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

        // Initialize connection parameters
        urlConnection.setConnectTimeout(30000);
        urlConnection.setReadTimeout(30000);
        urlConnection.setDoOutput(true);
        urlConnection.setRequestMethod("POST");

        // Headers initialization
        urlConnection.setRequestProperty("Content-Type", "application/atom+xml");
        urlConnection.setRequestProperty("Content-Length", String.valueOf(buffer.length));
        urlConnection.setRequestProperty("Authorization", mAuthToken);
        urlConnection.setRequestProperty("GData-Version", "2");
        urlConnection.setRequestProperty("X-GData-Key", YoutubeUtils.getDevKey());

        OutputStream os = urlConnection.getOutputStream();
        os.write(buffer, 0, buffer.length);
        os.flush();
        os.close();

        InputStream inputStream = urlConnection.getInputStream();

        inputStreamReader = new InputStreamReader(inputStream, "UTF-8");


        input = new BufferedReader(inputStreamReader, 4096);

        String strLine = null;
        while ((strLine = input.readLine()) != null) {
            response.append(strLine);
        }

        input.close();
        inputStreamReader.close();
        inputStream.close();
        urlConnection.disconnect();

        Log.d("CreatePlaylistTask", "Response: " + response);
    }
    catch(Exception e) {
        Log.d("CreatePlaylistTask", "Error occured: " + e.getMessage());
    }

    return true;
}

I have put together a sample Android application which uses the YouTube Data v3 API to demonstrate how you can load a playlist into a ListView.

https://github.com/akoscz/YouTubePlaylist

Note that you MUST have a valid API key for this sample application to work. You can register your application with the Google Developer Console and enable the YouTube Data API. You need to Register a Web Application NOT an Android application, because the API key that this sample app uses is the "Browser Key".

I'm assuming that the POST wasn't actually successful.

If I had to guess from looking at your code, I'd think that the problem might be the Authorization header value. What does myAuthToken look like, and what type of token is it? If it's an OAuth 2 token, for instance, then the value needs to be Bearer TOKEN_VALUE, not just TOKEN_VALUE.

Also, please note that v3 of the YouTube Data API will be released in the near future, and it will offer better support on Android using the new Google APIs Client Library for Java.
