Exoplayer 2.x.x

Get the current volume: int currentvolume = player.getVolume();
Mute: player.setVolume(0f);
Unmute: player.setVolume(currentVolume);

Exoplayer 1.x.x

I found two ways to achieve it by editing DemoPlayer from ExoPlayer.

Good one :

Basicly, you need to get the audioTrackRenderer which is a ExoPlayerComponent and send message to it. So :

1. Add audioRenderer member and set it in onRenderers:

   // Complete preparation.  
   this.videoRenderer = renderers[TYPE_VIDEO];  
   this.audioRenderer = renderers[TYPE_AUDIO];  
   

2. Add public method :

   public void setMute(boolean toMute){
       if(toMute){
           player.sendMessage(audioRenderer, MediaCodecAudioTrackRenderer.MSG_SET_VOLUME, 0f);
       } else {
           player.sendMessage(audioRenderer, MediaCodecAudioTrackRenderer.MSG_SET_VOLUME, 1f);
       }
   }
   

Usage :
mute : player.setMute(true);
unmute : player.setMute(false);

The other one :

This is not a good solution has the player will need to rebuffer when unmuting.
Consist of changing the audio track to an empty one:

// mute
player.selectTrack(FullPlayer.TYPE_AUDIO, ExoPlayer.TRACK_DISABLED);

// Unmute
player.selectTrack(FullPlayer.TYPE_AUDIO, ExoPlayer.TRACK_DEFAULT);
