I tried to dig through the some of the Topics to see if I could find a solution to no avail. How do I get my Script to recognize when a player declines a trade? causes my script to crash. I was digging through the API and thought maybe the Trade.RequestListener and capture the Message when they Decline the Trade "Other player declined the trade"? I tried testing it a little but I couldn't seem to get it working correctly so I am still not sure if that is the right solution? Any suggests or tips? There were a few Topics that have like mentioned it lightly but nothing in explicit detail. 

 @Override
    public void onMessage(Message msg) throws InterruptedException {
        if (msg.getType() == Message.MessageType.GAME && msg.getMessage().contains("Declined trade or what ever it says")) {
            //do stuff
        }
    }

MY MANNNNNNNNNN COMIN' in clutch thank you your too kind. I was actually kinda close in my code but I was for sure still off. THANK YOU!

Don't forget to add a null check, somehow it can at times return a null and be annoying, but that is my paranoia maybe ^^
version1:

@Override
public void onMessage(Message msg) {
    if (msg != null && 
        msg.getType() == Message.MessageType.GAME && 
        msg.getMessage().contains("Declined trade or what ever it says")) {
        // do stuff
    }
}

or return on null, depending on what u like:

@Override
public void onMessage(Message msg) {
	if (msg == null) {
		return;
	}

    if (msg.getType() == Message.MessageType.GAME && 
        msg.getMessage().contains("Declined trade or what ever it says")) {
        // do stuff
    }
}
