How to call a Youtube Data API through HTTPUrlConnection in Android with using headers?

Question

I am trying to develop a part of my app in which i want to get video details for a keyword. I am using the search list API. I think I have an issue with the authorization. I am getting a 401. I have tried passing my authorization details.

I have tried the following code after going through a few resources online and I am current getting the java.io.FileNotFoundException at the line at which i get the Input Stream. The connection code that I am getting is a 401.

The given code is in the doInBackground of an AsyncTask.

String ytres="";
        URL url;
        HttpURLConnection urlConnection = null;
        try {
            Log.d("youtubedata","a1");
            url = new URL("https://www.googleapis.com/youtube/v3/search?part=id&q=queen%20bohemian");
            Log.d("youtubedata","a2");
            Log.d("youtubedata","a");
            urlConnection = (HttpURLConnection) url
                    .openConnection();
            urlConnection.setRequestMethod("GET");
            urlConnection.setRequestProperty ("Authorization", "Bearer MYAPIKEY");
            urlConnection.setRequestProperty ("Accept", "application/json");
            Log.d("youtubedatanum",Integer.toString(urlConnection.getResponseCode()));
            InputStream in = urlConnection.getInputStream();

        InputStreamReader isw = new InputStreamReader(in);

        int data = isw.read();
        while (data != -1) {
            char current = (char) data;
            data = isw.read();
            ytres=ytres+current;
            System.out.print(current);
        }
        Log.d("youtubedata",ytres);
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (urlConnection != null) {
            urlConnection.disconnect();
        }
    }
    return ytres;

I do suspect the issue is in the way i have passed my API Key.

Please go through the API docs at Calling the API and at Search Endpoint.

You'll see that your URL does not contain the needed API key passed on as the key parameter.

It may also worth it to dug up Google's own sample Java implementation at Search.java. However, that code, due to the layer of library abstraction it uses, is not of immediate help since it obscures the way a client should work directly with the API.
