How to write requests to api in contact

Here is an example of how to request a list of audio records as a result of a search by title. There you can run the song. In my case, the first song in the list is launched.

Description of the code snippet from memory:

1. Create a VKRequest object for the request.

2. We pass on to him that for the request we will do the parameters - the name of the track and the constant (unfortunately I forgot what it does).

3. We carry out the request and set him a listener.

4. In response, a response comes in and the onComplete method is executed (there are several other methods for different cases, for example, an error).

5. Parsim received JSON in the model for the track and we have a list of songs.
6. Select the first item from the list (as the best option).

7. My implementation of song playback.

   public void searchTrack(String trackName) { VKRequest searchSongRequest = new VKRequest("audio.search", VKParameters.from(VKApiConst.Q, trackName)); searchSongRequest.executeWithListener(new VKRequest.VKRequestListener() { @Override public void onComplete(VKResponse response) { super.onComplete(response); ArrayList<VkTrack> trackList = VkTrack.parseJSON(response.responseString); String song; if (trackList != null) { song = trackList.get(0).getArtist() + " - " + trackList.get(0).getTitle(); AppData.sSongUrl = trackList.get(0).getUrl(); Log.d(TracksSearcher.class.getSimpleName(), song); Log.d(TracksSearcher.class.getSimpleName(), AppData.sSongUrl); } else { Log.e(TracksSearcher.class.getSimpleName(), "trackList is null"); } AppData.sAudioPlayer.play(mContext, AppData.sSongUrl); AppData.isSongPlayed = true; } }); 

   }
