Function call doesn`t work in ConstructL() but at other places it works fine, why?

[Besieger]

Hi, I wrote a programm, which should get the IMEI at startup. I implement the IMEI-program from the WIKI.
When I call the IMEI-function in the UI-constructor my program give me on a device the error message: Program closed.
On the 3rd edition emulator the program works fine and it works also fine at devices with 2nd edition sdk. Only at devices with 3rd edition it doesn`t work.
I use a developer certificate with all available capabilities.

Have anyone some suggestions or an explanation? I`m really confused, why it doesn`t work in the constructL() at 3rd edition.

There could be several things.. try posting a snippet, and let us know the specific error (panic) you're getting. Search the forum for explanations to achieve this.

BTW, which IMEI reading code are you using ?

As far as know the CTelephony does not work with 2nd edition (or maybe I have never tried), but has worked just fine with me when constructed in Appui's ConctructL function.

I use the Imei-Function, which get the imei synchronously.
This is the cpp-file:

#include "SMSExampleValidate.h"
 
void CGetImei::GetIMEI(TDes& aIMEI)
{
	CGetImei* self= new (ELeave) CGetImei(aIMEI);
	CleanupStack::PushL(self);
  	self->ConstructL();
	CleanupStack::PopAndDestroy(self);
}
 
void CGetImei::ConstructL()
{
        //if( iStatus =! KRequestPending )
	//{	
        iTelephony = CTelephony::NewL();
	CActiveScheduler::Add(this);	
	CTelephony::TPhoneIdV1Pckg iPhoneIdV1Pckg(iPhoneIdV1);
	iTelephony->GetPhoneId(iStatus, iPhoneIdV1Pckg);
	SetActive();
	CActiveScheduler::Start();
        //}
}
 
CGetImei:: CGetImei(TDes& imei): CActive(EPriorityStandard),IMEI(imei)
{
    //default constructor
}
 
CGetImei::~CGetImei()
{
    delete iTelephony;
    iTelephony = NULL;
    
    Cancel();
}
 
void CGetImei::RunL()
{
    if(iStatus==KErrNone)
    {
	IMEI= iPhoneIdV1.iSerialNumber;
	CActiveScheduler::Stop();
    }
}
 
void CGetImei::DoCancel()
{
    iTelephony->CancelAsync(CTelephony::EGetPhoneIdCancel);
}

I think my code is right, because I get it from the Wiki and at other places in my program it works fine. Only in the ConstructL() from the UI it doesn`t work. I suppose that something is wrong with other active functions. I tested under the above ConstructL() the if-loop with KRequestPending. With the loop my program starts, but didn`t read the IMEI.

I don´t know, what I can further do?
Have you some ideas?

Basically, if you would just take the code as it is given in the Wiki it would work. I personally wrote that and tested it, and it doesn't re-assemble your code really...Thus make it easy for your self and copy paste the code from the Wiki without modifications....
