hi


i have a problem with the garbage collector (i think ). my graphic routine runs wery well and i can get 15-20 fps from it with out any problems. but sometimes my scroll routine hacks.
i have checked for any lose variables, and everything that could make the GB run.
is there any method for keeping the GB in place.

the small pauses it makes, have a even time interval.

ive tried to put System.gc() calls in my code , at different places but it has no effect.


please help.... im so close to finish

You can check amount of used/free memory using Runtime like this:

Runtime rt = java.lang.Runtime.getRuntime();

System.out.println("Total mem: " + rt.totalMemory());
System.out.println("Total free: " + rt.freeMemory());

If you don't use Nokia specific classes, you may find Sun Memory Monitor more convenient. It's included to Wireless Toolkit and will even show you how much memory every object eats

I suggest that make a test version, and in this version draw the free memory and the frame-time on the canvas. It will flickering, but readable, and uesefull. You will see, that you canot avoid GC running. Of course, printing test results makes new strings and a little sophisticated results.

Yah, love the Sun's WTK.

We commented the Nokia's UI API whenever we use Sun's WTK, although it might not be as accurate, but it gives a good idea on how things might work down the road.
