Panic KERN-EXEC 3 Error

[vshnuforu@yahoo.co.in]

Hi all,
I am in the midst of developing my first symbian application which solely based on the forum nokia thread about retriving the incoming/outgoing calls .
http://wiki.forum.nokia.com/index.php/TSS000685_-_Retrieving_incoming_and_outgoing_call_numbers
It is jus a simple d60 GUI application which handling an active object CallLogNotifier.
I got kernel panic error when i run it on the emulator .then i trued debugging i got one more error dialog
application closed:!WidgetRegistry ALLOC:36c62aa40 before the kernel get panic.

i can find that the error is based on the code statement
iTelephony->NotifyChange( iStatus, CTelephony::EVoiceLineStatusChange, lineStatusPckg );


my source code for both the active object and a simple application view are given..
please give me a solution.

You have not allocated the memory for iTelephony object, you have simply declared it in header.

Write the following in ConstructL(): iTelephony = CTelephony::NewL();

[vshnuforu@yahoo.co.in]

hi vineet.jain,
Thanks for the solution... Now its working...
You know What happen to my application when a call gets active..? It might terminate????

[symbianyucca]

hi vineet.jain,
Thanks for the solution... Now its working...
You know What happen to my application when a call gets active..? It might terminate????

What do you mean by that ? Basically it depends on your logic and what you do there. Anf if your application suddenly terminates, then do check what panic code you get, and see whwther you can find the code part that causes the panic.

[vshnuforu@yahoo.co.in]

hi sir,
I meant what happened to my application when an incoming call in progress.. will it closed or will it notify???
please help

[symbianyucca]

You should really test that by yourself, and see how it behaves. It appears to be monitoring call and then notifying the state changes, though you should re-start the monitoring in RunL, so it would also get more than one event..

thank you very much mr sumbianycca...
i understood it...thanks again..

i developed this using s60 5th edition sdk and carabide c++ ide, but i have only nokia E65 device on testing.... how can i test ..please help me again sir?

[vineet.jain]

well compile your project for phone release, make a sis file for it & install it in your device.

[symbianyucca]

I would strongly suggest using 3rd ed MR SDK with the E65 device, since it is original 3rd ed MR device. The 5th edition SDK is basically meant for building for 5th ed touch devices.

where is the implementation of CallStatusChangedL method?

i posted what you have asked..please give me a solution..its really urgent..

Thanks in Advance

[mekal2002]

your code seems ok but i suspect the following lines
CreateListBoxItemL( listString, buf );
AddListBoxItemL( iListBox, listString );
iListBox->SetCurrentItemIndexAndDraw(iListBox->Model()->NumberOfItems()-1);

I want to veryfy that the caller no. is coming in call back method or not, I suspect that the Item are not getting updated in your UI,

Now to check that whether you are receiving the caller no. in correct format , write some file log insilde the CallStatusChangedL() method. and try to write buf into the log file.

[mekal2002]

also try this

instead of

iListBox->SetCurrentItemIndexAndDraw(iListBox->Model()->NumberOfItems()-1);
call
iLiiListBox->HandleItemAdditionL();
