MediaPlayer can't turn volume back up

Question

Hello i am working on little android app witch has some sounds. I am trying to make a toggle style button to enable/disable the audio. I tried it this way. The audio plays fine oncreate and when i click the button once it goes off like it's supposed to but it won't come back on

boolean volon = true;

player = MediaPlayer.create(this, R.raw.aud);
player.setLooping(true);    
player.setVolume(100,100);
player.start();

volumebtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (volon) {
                player.setVolume(0, 0);
                volumebtn.setImageResource(R.drawable.voff);
                volon = false;
            }else {
                player.setVolume(100, 100);
                volumebtn.setImageResource(R.drawable.von);
                volon = true;
            }
        }
    });

Log cat output:

The logcat confirms the audio is being toggled from 0 to 100 yet i don't hear any audio.

Answer 1

Try using a value between 0.0f and 1.0f

MediaPlayer.setVolume()
