Hello zahangir,

If your code design is ok, there should not be any problem. It will be more convenient if you post some of your code sniffet here.

By the way, how many views are there in your code? and the important thing is that the SetOrdinalPosition will be used in anywhere successfully if used in proper way.

If possible post the ur view::ConstructL(), DoActivateL() and container::ConstructL() and phone::RunL() part to better recognise the problem.

Tushar

Hi Tushar,

I have done it but still some times it works fine but some times it does not work, it goes to background Telephone app comes foregorund. I am working in Symbain 9.1 and using CTelephony API. What I have done that are as follows

1. My Incoming call notifier is an CActive Object. And set it EPriorityHigh
2. SetProcessPriority as high from ConstructL of AppUi
3. SetThreadPriority as high from ConstructL of AppUi
4. Bring to foreground using SetOrdinalPosition on Incoming call

Is there any trick is missing.....

If any idea the please share it.

Hello Zahangir,

try this code in side your BringForeGroundL() instead of TApaTask.

Code:

RWindowGroup iMyWindowGroup2 = iCoeEnv->RootWin();
iMyWindowGroup2.SetOrdinalPosition(0,ECoeWinPriorityAlwaysAtFront);

and let me know whether it worked.

Tushar

Hi Tushar,

According to some solutions about it, I have understood that three main things are important those are.
1. CActive with 'EPriorityHigh' for incoming call listener
2. Application's thread with 'EPriorityAbsoluteHigh'
3. BringForeGround using TApaTask

I have tried this within the following code. But Still native caller screen seen. MyTest1 application comes foregroundand then goes background and then native caller screen comes foreground.

I am sure that definitely some mistakes are here. Please clear it.

My development Points are:
0. SDK: S60 3rd edition and CTelephony API
1. My application name is : MyTest1
2. I have created a call manager for income call listenter with CActive( EPriorityHigh ). CallManager class is like this:
----------------------------------------------------------------
class CCallManager : public CActive
{
public:
static CCallManager* NewL(CTelephony* aTelephony, CInCallListener & aInCallListener);
void Start();
void Stop();
public:
virtual ~CCallManager();
private:
CCallManager(CTelephony* aTelephony, CInCallListener & aInCallListener);
void ConstructL();
private:
void RequestNotification();
protected:
virtual void RunL(); // Inherited from CActive
virtual void DoCancel();
private:
CTelephony* iTelephony;
CInCallListener & iInCallListener;
CTelephony::TCallStatusV1 iLineStatus;
CTelephony::TCallStatusV1Pckg iLineStatusPckg;
};

//Start of CallManager.cpp file
CCallManager* CCallManager::NewL(CTelephony* aTelephony, CInCallListener & aInCallListener)
{
CCallManager * self = new (ELeave) CCallManager(aTelephony, aInCallListener);
CleanupStack::PushL(self);
self->ConstructL();
CleanupStack::Pop(self);
return self;
}

void CCallManager::Start()
{
Cancel();
RequestNotification();
}
void CCallManager::Stop()
{
Cancel();
}
CCallManager::CCallManager(CTelephony* aTelephony, CInCallListener & aInCallListener)
: CActive( EPriorityHigh ),
iTelephony(aTelephony),
iInCallListener(aInCallListener),
iLineStatusPckg( iLineStatus )
{
iLineStatus.iStatus = CTelephony::EStatusUnknown;
CActiveScheduler::Add(this);
}
CCallManager::~CCallManager()
{
Cancel();
}
void CCallManager::ConstructL()
{
}
void CCallManager::RequestNotification()
{
if(IsActive())
{
return;
}
if(iTelephony)
{
iTelephony->NotifyChange( iStatus, CTelephony::EVoiceLineStatusChange,
iLineStatusPckg );
SetActive();
}
}
void CCallManager::RunL()
{
if( iStatus==KErrNone )
{
if( iLineStatus.iStatus == CTelephony::EStatusRinging )
{
// Answer call by calling 'AnswerIncomingCall()'
iInCallListener.NewInCallArrived();
}
}
}
void CCallManager::DoCancel()
{
if(iTelephony)
{
iTelephony->CancelAsync( CTelephony::EVoiceLineStatusChangeCancel );
}
}
//end of CallManager.cpp file
3. Application's priority setting is:
//SetPriority Code
void CMyTest1AppUi::SetPriority()
{
#if !defined(__WINS__) //FIXFIXME
CEikonEnv::Static()->WsSession().ComputeMode(RWsSession::EPriorityControlDisabled);
RThread T;
TFindThread fr(_L("MyTest1*"));
TFullName fn;
if (fr.Next(fn) == KErrNone) //for thread
{
if (T.Open(fn) == KErrNone)
{
T.SetPriority(EPriorityAbsoluteHigh);
T.Close();
}
}
#endif
}
// end of SetPriority Code

4. BringForeGround code
//BringForeGround
void CMyTest1AppUi::BringForeGroundL()
{
// Construct en empty TApaTask object
// giving it a reference to the Window Server session
TApaTask task(iEikonEnv->WsSession( ));

// Initialise the object with the window group id of
// our application (so that it represent our app)
task.SetWgId(CEikonEnv::Static()->RootWin().Identifier());

// Request window server to bring our application
// to foreground
task.BringToForeground();
}
//end of BringForeground

5. on incoming call notification from CallManager
//Code
void CMyTest1AppUi::NewInCallArrived()
{
BringForeGroundL();
ShowGlobalConfQueryL();
}
//end code

-------------------------------------------------
Could you verify it?

Zahangir

Hello Zahangir,

Did you mean problem regarding setting app foreground during incoming call ?

In that case use SetOrdinalPosition(). search on this forum and also in the SDK to know how to use it. You can use this method to set ur app on top of everything even the system incoming dialog.

Plz specify ur probelm in more detail if posible if this is not requirement.

Hi,

I am fetching some problem application foreground when there is an incoming call.

Do you have solved this?
If yes, please post some sample code.
If it is possible please send me a copy to zahangirbd@gmail.com

I have solved the app hang problem ( well, without a single reply from anybody ). My app code was requesting two asynchronous methods simultaneously.
