title: How to reference resId's from MainActivity to Service
body: <p>I'm having to move my MediaPlayer outside of the MainActivity and into a Service.</p>
  
  <p>My code currently has all of the buttons hosted within the MainActivity however when the button is pressed, an ID (resId) is assigned to it so that I can use general MediaPlayer code to play any button that is pressed.</p>
  
  <p>For example:</p>
  
  <pre><code>public void onClick(View v) {
      int resId;
      switch (v.getId()) {
      case R.id.button_1:
          resId = R.raw.birdsong;
          break;
      case R.id.button_2:
          resId = R.raw.brown_noise;
          break;
      case R.id.button_3:
          resId = R.raw.car_journey;
          break;
      case R.id.button_4:
          resId = R.raw.crackling_fire;
          break;
      case R.id.button_5:
          resId = R.raw.electrifying_thunderstorms;
          break;
      case R.id.button_6:
          resId = R.raw.fan;
          break;
      case R.id.button_7:
          resId = R.raw.jungle_river;
          break;
      case R.id.button_8:
          resId = R.raw.pig_frogs;
          break;
      case R.id.button_9:
          resId = R.raw.pink_noise;
          break;
      case R.id.button_10:
          resId = R.raw.predawn;
          break;
      case R.id.button_11:
          resId = R.raw.rain;
          break;
      case R.id.button_12:
          resId = R.raw.shower;
          break;
      case R.id.button_13:
          resId = R.raw.snoring;
          break;
      case R.id.button_14:
          resId = R.raw.whale_song;
          break;
      case R.id.button_15:
          resId = R.raw.white_noise;
          break;
      default:
          resId = R.raw.birdsong;
          break;
      }
      // Release any resources from previous MediaPlayer
      if (mp != null) {
          mp.release();
      }
      // Create a new MediaPlayer to play this sound
      mp = MediaPlayer.create(this, resId);
      mp.setLooping(true);    
      mp.start();
  </code></pre>
  
  <p>How would I be able move the code to a service, but still have the buttons on the MainActivity? The service will not recognise the resId associated with the button as all of the code will be in MainActivity and so will not play the correct sound.</p>
