J2ME: can you clear the key pressed buffer on a cell?

Question

I am having trouble with keypressed.
I am writing a cell phone game in MIDP 2.0. Basically its the standard GameCanvas setup, where you have a main game loop and it calls your input function. The input function then does:
int keyStates = getKeyStates();
keyprocessing
to get the states.
When I demo it on the color phone in WTK2.0, and tap the right arrow, and my input loop processes the right multiple times. My initial thought was that the loop ran too fast perhaps and it read the press several times, so I put in a delay before keyprocessing:
int keyStates = getKeyStates();
long time = System.currentTimeMillis();
if ((time - timeOfLastInput) < MIN_TIME_INPUT)
return;
keyprocessing
timeOfLastInput = System.currentTimeMillis();
Now, I have cut it down to only going in a direction once. However, if I press up, down, left, right, (in honor of Konami) My input goes as follow Up (delays MIN_TIME_INPUT) then Down, delays again, left, delays, right.
And so I am out of ideas.

Answer 1

haha, this is interesting... a month ago, i had the same problem, until i flash of intellect put me out of my misery...
rule 1: dont use the time delay. with the processor speed of the cell phones, with your delay, it will take a decade before the app runs...
heres how to do the coding to keep it to only 1 step at a time: ( i do it in the run method of the thread)
int originalKey = 0; // keeps the keystates once the execution completes once
int key = 0; // keeps the keystates for comparision
while(isRunning) {
    key = getKeyStates();
    if(key == originalKey) {
        originalKey = 0;
        continue;
    if( (key & LEFT_PRESSED) != 0) {
        // do what you want to do, or who you want to do
        originalKey = key;
// do the same for right pressed and etc etc... this will keep your code from executing too many timesheheh... i think i deserve a few dukes...
