{color:#000080}The variable ml is declared but is null since you have never assigned a value to it. This is the correct approach:
-- pass a reference to MyWatch to the constructor of MyWatchCanvas
-- retrieve the reference to the instance field ml
In MyWatchdisplay.setCurrent (new MyWatchCanvas (this, display));In MyWatchCanvas constructorMyWatchCanvas (MyWatch ml, Display display)
   this.ml = ml;
   this.display = display;etc.
This code is inefficientif(watchStop==false)
   watchStop=true;
else
   watchStop=false;
}You do not test comaprison against true and false. This is betterif (watchStop)
   watchStop = false;
else
   watchStop = true;
}but this is what you should be doingwatchStop = !watchStop;in one line.
There may be more wrong with your code, if you like you can repost with these corrections, and within code tags, for further review.
