I am trying to initiate HttpConnection at every 1min (or whatever interval the user supplies) but the thread.sleep() method I am using causes the whole phone to freeze for 1min instead of spacing the recursive HttpConnection call by 1min.


-----------------------------
private void getInterval()
{
_sleepThread.run();
fetchStock();
getInterval();
}
----------------------------
private static class SleepThread extends Thread
{
public void run()
{
try {
sleep(60000); }
catch ( InterruptedException e) {}
}
}
----------------------------

The fetchStock() method calls the HttpConnection method in another private thread class which retreives the webpage, retrieval is synchrozied to prevent another call being made while the previous one is still working.

The BlackBerry freezes whenever i call "_sleepThread.run()" from getInterval() method in the main class of the application.

Is there another way to pause the recursive getInterval() method for a particular interval?

The BlackBerry becomes unresponsive to any keypad input for exactly the amount of milli-seconds specified in the thread.sleep(TIME) method, then goes on to execute the HttpConnection request.

I dont want the BB to freeze, I only want to pause the recursive call.

What am I doing wrong?

Are you ever unwinding that recursion? You'll run out of stack eventually if you don't.

Anyway, you're treating SleepThread like a Runnable instead of a Thread. Use "start" instead of "run".

Thx for the response, this is my first BlackBerry application so I am not yet very familiar with the syntaxes.

How do I unwind the recursion?
Where am I to change "run" to start? In class SleepThread or I should change the calling method from _sleepThread.run() to _sleepThread.start()?

Maybe you should look into Timer and TimerTask. Schedule your http connection to occur on an interval. That will take care of a lot of the dirty work for you. Concurrency *and* mobile is kind of a big intro to Java programming.

Thx richard, Timer/TimerTask did the trick though I had to create an additional "runnable" thread class that calls the timer class.
