Always do 'previous instance still active' help SDK 2.3 Webworks

My application is quite simple:

  • request ajax jquery (1.3.2) to the JSON web service to get a list of items
  • Browse the results to produce the list (about 20-30 items in the list)
  • clicks of the user on the point that launches another call ajax for billing details
  • to exit, I call system.exit() using the API
  • the application uses no custom extensions
  • in the application, I also use the messages and calendar API (for sending and adding reminders)

After a few sessions to use the application, I get the error of «Previous instance still active» (report http://go/memoryleaks) I know that the GC is called as I see the spinning out of clock.

in the application on OS7 Manager, I see that the app is more than 2 MB of memory sometimes.

Can anyone suggest what aspects of my application is originally memory leaks still?

Thank you

I've isolated the offending script

I used the API to manage the key features of return (which worked as expected), somehow even on WW 2.3 SDK still is not releasing the back key listener. my code to handle previous key:

function trapForBackKey() {}
blackberry.system.event.onHardwareKey (blackberry.system.event.KEY_BACK, handleBack);
}

function handleBack() {}

If ($("#panel1").css ("display") is "none")
{
showPanel (document.getElementById ('tab1'), 'panel1');
}
on the other
{
BlackBerry.app.Exit ();
}

}

Of course I would have preferred to be able to control the previous button without getting the error, but for now, I'm leaving it.

Any ideas on how to control the previous button and make sure that the listener on the coast of JAVA came out?

  • My experience and a further debate on "the previous instance is still active.

    Hi, expert,

    I came across this problem to my application UI last a day and spent some time in this. The reason of the root, I discovered, is that the code does not call a code specific to one of the close method (last screen), so the following will not be cleaned:

    1. my entire user interface application is put into running store

    2 global envent listener for my application Ui

    After debugging, I discovered that this is due to the #1.  However on debugging time, I found that this problem is actually very difficult to debug because reproduce is inconsistent. So, even every time, I don't clean my application user interface of the store of my last screen of UI runtime user close, the will of "the previous instance is still active" appear after a certain (it seems to me that I should also leave my open screen for just a little bit time as well). So although I could not reproduce this problem anymore after the method of the last screen you add code to clean up close, I can't say 100% here that I solved the problem.

    It would be appreciated if someone would confirm the reproduction behavior of his that I've seen here.

    In this position, he also spoke against putting the entire application in the TERM store:

    http://supportforums.BlackBerry.com/T5/Java-development/UiApplication-put-into-RuntimeStore-vs-make-...

    I think that I should remove the code to put together Ui App store time anyway.

    I also searched the forum, I think the following 2 positions are most useful:

    In the post, he said that he should be careful with the external auditor. For my purposes of background, I used the earpiece of the phone and found out that he would be called to the phone application. However, other headphones I've used as follows, I haven't not because they are called to external applications (must be in the thread principal current substantive application event)

    SystemListener2

    CoverageStatusListener, RadioStatusListener, WLANConnectionListener

    CodeModuleListener

    ApplicationMessageFolderListener

    Should I bother with the earphone as well?

    I suggest to cancel the registration of all and each listener when your application stops.

  • Previous instance of the pilot still in memory - hard drive Ext

    It is on a disk Toshiba external hard usb connected to a w XPS8700 8.1 which works fine on other computers. The error message -cannot load the driver the previous instance of the device still in memory driver. I uninstalled the drive ext devices and printers where it appears with an exclamation mark and error message, rebooted, removed and reconnected to the diff, usb ports, changed power outlets, registered disk management - does not appear there or to Mgr. Unit nothing works. Yet to test it on my another victory 8.1 computer recognizes it immediately and I have access to all files.  It scans the drive and found no errors. Files can be moved to the other hard drive. The ext drive works OK on the 8700 for more than a year.

    edit -- found the reason - USB Mass Storage Device has the error -previous instance... still in memory. Any suggestions? Uninstalling and restarting does not help. Diagnostic tests were all very well.

    The fixed! This was caused by Pépin of the history of the files. (I hate file history) I opened Device Mgr, selected hidden devices and found an old entry of WD ext hard drive and deleted. Historical files should be disabled before changing anything. because it gave me errors on the disc Toshiba not found or not connected. I had disabled the USB storage device and had to re - activate. This requires a reboot, and the Toshiba external drive is now active and functional.

    I am leaving the history of files and make manual backups instead.

    There is no exchange of free display.  You will pay is the AppleCare + fresh incident (if you bought AC +), or the elimination of guaranteed replacement costs / costs of replacing the screen.  Your best bet would be to visit the Apple store with a genius bar appointment.

  • menus are gray but still active

    updated thunderbird a few months back. Continuing the problem with greyed out, along the top of the menu and right click etc. They are still active, if you click it, the function works. The menu appears sometimes after a few seconds, sometimes one minute, sometimes never!
    Have you tried to go to continue in safe mode that works but in bulk all the books of customization and address etc.
    Reset toolbars and controls makes no difference. Disable all add them ons also makes no difference.
    Installed add on "disable add the compatibility check" without success.
    Using windows 7

    Try Tools-Options-Advanced and uncheck the box "use hardware acceleration when available. Turn it back on.
    I suggest this because you mentioned that Safe Mode solves the problem, but disabling modules has no effect. Safe mode does both.

  • How to check a timertask calendar is still active or not?

    Hello

    I created the following code:

    class StateTracker extends TimerTask
    {
    Minu private;
            
    public StateTracker()
    {
    Timer = new Timer();
    Timer.Schedule (this, 5000, 150000); begins after 5seconds Repeat task every 150 seconds
    }

    public void run()

    ....

    }

    The code runs allright, unless, in certain circumstances, the task stopped after a few periodic race (I suspect is disconnected network). Y at - there any API I could use to check whether the calendar is still active or not.

    I would like to reschedule the timertask if the original schedule was disrupted.

    timertasks should not be used for the treatment of blocking. I would say to put the actual work load in an own thread.

    as long as the enforcement code is surrounded by exception handling, execution continues. There is no method to check if the timer is running correctly.
