I have been stuck on this for way too long (4 hours yesterday, 3 hours today!) now. In my main menu screen, I have a mute button. I want it to call a method in my background service, which mutes all of the MediaPlayer audio that would be played in the background of my game.
Here is something that might be causing the issue:
I am getting the error whenever the audio plays (which plays fine):
QCMediaPlayer mediaplayer NOT present

Here is the method in Main_Menu (x starts as zero)
if ((x%2) == 0) { //If it's even
TwentySeconds.unMute();
Toast.makeText(Main_Menu.this, "UNMUTED", Toast.LENGTH_SHORT).show();
x++;
} else { //If its odd
TwentySeconds.myMute();
Toast.makeText(Main_Menu.this, "MUTED", Toast.LENGTH_SHORT).show();
x++;
}

I would really appreciate any feedback (positive or negative)! Let me know if you need any thing else. Thanks so much for everything, I hope I can solve this issue... :)
