Hi All,

I am developing one BB aplication where Ineed to use Global Screen. My application stops after running for sometime and shows Outof memory error. A have checked the display stack. the count shows 118.

My program works with GLOBAL_SHOW_LOWER as like below

Ui.getUiEngine().pushGlobalScreen(screen,0,UiEngine.GLOBAL_SHOW_LOWER);

what might be the possible cause. how do i empty the stack.  or is it for any other reason.

Thanks in advance.

Are you closing these global screens?

Hi,

No. I am not closing Global screen. the VM is showing as below..

Post the exception stack trace.

VM Stack

0x03896000

[RexDoug]

That is not the stack trace. I wonder how you expect to successfully create programs if you cannot perform basic problem determination?

Is this on the device or the simulator? If you can duplicate the issue on the simulator, you can view the call stack at the time of the exception. This call stack will show you the sequence of method calls leading yup to the point of the exception.

If this is the device, the stack trace must be retrieved from the device event log, or by duplicating the issue while the device is attached to the debugger.

Sorry, I copied the wrong stack.

Nothing jumps out at me - can you post some code where the exception occurs?

[peter_strange]

How big is the Bitmap you are creating?

Actually I am trying to display a clock on my homescreen. I am drawing 3 hands of the cloch using bitmap & rotate method. I am able to get them all on my homescreen but when the soconds hand reaches some perticular point, the application throws out of memory error.

UiApplication.getUiApplication().invokeLater(new Runnable(){
     public void run(){
          try{
             TestClockHands screen =new TestClockHands();  
             screen.loadCanvas(count,secVect,minVect,hourVect,index,index1);  
             synchronized(Application.getEventLock()){
                     Ui.getUiEngine().pushGlobalScreen(screen, 0, UiEngine.GLOBAL_SHOW_LOWER);
                     }
            }catch(Exception e){
                                System.out.println(e);
                     }
             }
             });
