Step 1 : Getting Video ID

public static String extractYTId(String ytUrl) 
{
    String vId = null;
    Pattern pattern = Pattern.compile(
            "^https?://.*(?:youtu.be/|v/|u/\\w/|embed/|watch?v=)([^#&?]*).*$",
            Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(ytUrl);
    if (matcher.matches()){
        vId = matcher.group(1);
    }
    return vId;
}

Step 2 : Getting Video thumbnail image from Youtube API

I used my EasyTool library to load image.

{
    img.L("http://img.youtube.com/vi/"+video_id+"/0.jpg");
}

Step 3 : Make a Request to Youtube in MP3 API

Just make a UrlConnection and use inputstream to get converted file.Example usage is up there.

{
    new AsyncTask().execute("http://www.youtubeinmp3.com/fetch/?video=https://www.youtube.com/watch?v="+ **VIDEO_ID** ");
}

Step 4 : Getting Video Title

We need the title of video to writing name of converted mp3 file. I used HttpRequest Library. It's a very useful library if you want to avoid code complexity and more.

{
                HttpRequestFactory factory = new HttpRequestFactory(getApplicationContext()) {
                @Override
                public void Happens(RIO rio) {
                    JSONObject object = rio.response_json;
                    try {
                        video_title = object.getString("title");
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                    
                }
            };
            factory.executeRequest(RequestType.GET,"http://www.youtubeinmp3.com/fetch/?format=JSON&video=https://www.youtube.com/watch?v="+**VIDEO_ID**,null);
}
