Google TV

Media keys

Google TV keyboards have seven media-control keys that are mapped to KeyEvent constants. These are listed in Table 1. If your application plays music, displays video or or runs a slide show, you can handle these control keys in the android.view.View.onKeyDown() callback for the View that controls the media.

Note: The media-control keys for Android versions prior to 2.3 (Gingerbread) are not supported.

Action KeyEvent keycode constant Keyboard Symbol1
Start playback KeyEvent.KEYCODE_MEDIA_PLAY illustration of a play button
Pause playback KeyEvent.KEYCODE_MEDIA_PAUSE illustration of a pause button
Stop playback KeyEvent.KEYCODE_MEDIA_STOP illustration of a stop button
Next KeyEvent.KEYCODE_MEDIA_NEXT illustration of a next button
Fast-forward KeyEvent.KEYCODE_MEDIA_FAST_FORWARD illustration of a fast-forward button
Previous KeyEvent.KEYCODE_MEDIA_PREVIOUS illustration of a previous selection button
Rewind KeyEvent.KEYCODE_MEDIA_REWIND illustration of a rewind button

This code snippet demonstrates how to handle media key events:

 * Overrides the callback method for a UI control handling a slideshow
public boolean onKeyDown(int keyCode, KeyEvent event) {

   * Chooses the action to take, based on the incoming keycode
  switch (keyCode) {
    case KeyEvent.KEYCODE_PAUSE:
      Log.d("MediaPlayer", "Pausing the slideshow");

      if (slideshow.pause()) {

      return true;

    case KeyEvent.KEYCODE_MEDIA_PLAY:
      Log.d(TAG, "Resuming the slideshow");
      if (slideshow.resume()) {

      return true;

     * Keycodes should always be passed upwards in the chain for handling.
      return super.onKeyDown(keyCode, event);
