Problem in launching web browser in S60 3rd Edition

[sahidul]

I wanted to launch a web browser with a page opened by default. The application works fine. But the url is openeing in a popup in the browser. So if I open the url more than 5 times it does not allow me to open it as the maximum no of opened popup is 5 in my Nokia E71.
I used the following code
HBufC* param = HBufC::NewLC( 20 );
param->Des().Copy( _L( "4 http://www.yahoo.com/" ) );
const TInt KWmlBrowserUid = 0x10008D39;
TUid id( TUid::Uid( KWmlBrowserUid ) );
TApaTaskList taskList( CEikonEnv::Static()->WsSession() );
TApaTask task = taskList.FindApp( id );
if ( task.Exists() )
{
task.BringToForeground();
HBufC8* param8 = HBufC8::NewLC( param->Length() );
param8->Des().Append( *param );
task.SendMessage( TUid::Uid( 0 ), *param8 ); // Uid is not used
CleanupStack::PopAndDestroy();
}
else
{
RApaLsSession appArcSession;
User::LeaveIfError(appArcSession.Connect()); // connect to AppArc server
TThreadId id;
appArcSession.StartDocument( *param, TUid::Uid( KWmlBrowserUid ), id );
appArcSession.Close();
}
CleanupStack::PopAndDestroy(); // param

I even tried to close the browser and restart the task, but failed to do so. I used the following code
const TInt KWmlBrowserUid = 0x10008D39;// 0x1020724D for S60 3rd Ed

TUid taskId( TUid::Uid( KWmlBrowserUid ) );
TApaTaskList taskList( iEikonEnv->WsSession() );
TApaTask task = taskList.FindApp( taskId );
TBool taskClosed = ETrue;
if ( task.Exists() )
{
taskClosed = EFalse;
task.BringToForeground();
//task.KillTask();
task.EndTask();
//task.SendSystemEvent(EApaSystemEventShutdown);
for(int i=0;i<500;i++)
{
DoSomeOperation();
taskClosed = ETrue;
TApaTaskList taskList2( iEikonEnv->WsSession() );
TApaTask task2 = taskList2.FindApp( taskId );
if(!task2.Exists())
{
taskClosed = ETrue;
break;
}
}

}
if(!taskClosed)
return;
....the code for openeing a new browser continues here

With this code the browser is closed, but it does not restart in the same session.

I saw the cellspotting(http://www.cellspotting.com) application, it opens the browser more than 5 times without any problem.

I tried with Nokia Browser Launch API, but when I restart my application without closing it, the browser is in front of the application which is not the required feature of the application.

Can anybody help me?

Hello,

I am having a similar problem using the same code on the E71 as well. I believe the original code came from this Wiki article:

http://wiki.forum.nokia.com/index.ph...in_3rd_edition

In my case, the code works great if the browser isn't already running. But when the browser is already running, the browser is brought to the foreground, but the URL isn't opened. The web page previously opened in the browser remains active. I do however see a "flash" on the browser window, which leads me to believe that some (error?) message is being displayed, although too quickly to be read.

My application follows the window client/server model, and so I use a RWsSession for the task list:

RWsSession wsSession;
User::LeaveIfError(wsSession.Connect());
CleanupClosePushL(wsSession);

TApaTaskList taskList( wsSession );
TApaTask task = taskList.FindApp( id );

My code is otherwise identical to the sample code provided in the Wiki article.

I've also tried the CBrowserLauncher approach:

http://wiki.forum.nokia.com/index.ph...r_Launcher_API

Unfortunately the call to LaunchBrowserEmbeddedL crashes in my app with a "data" error. My guess is this is related to the window client/server model:

CBrowserLauncher *launcher = CBrowserLauncher::NewL();
launcher->LaunchBrowserEmbeddedL( *param, NULL, NULL, iOverriddenSettings );
CleanupStack::PopAndDestroy();

I'd certainly appreciate any tips to make the browser launch work on the E71 when the browser task is already running.

Best regards,
Brian

The actual panic code could help, check this for help: http://wiki.forum.nokia.com/index.ph...ded_panic_code

Hello,

Thank you for the quick reply. Using the CBrowserLauncher class, my application crashes with a KERN-EXEC 3 error. From what I've read, this usually indicates a stack overflow. Looking at the calling chain, I don't believe an excessive amount of recursive functions are on the stack. Also substituting the code used by sahidul for the CBrowserLauncher implementation eliminates the KERN-EXEC 3 error, so maybe the error is caused by something else.

I currently specify a 20 KB stack using the EPOCSTACKSIZE directive. For grins I increased that to 32 KB and unfortunately that made no difference.

It seems like this code nearly works perfectly, except that when the browser is already running, the new URL is not opened:

http://wiki.forum.nokia.com/index.ph...in_3rd_edition

So my preference is to sort out why the E71 browser fails to open in this case. The flash in the browser window when trying to open the new URL is telling... I wish I knew what failed! Could it be cause by some browser preference?

Thanks again for helping with this issue.

Regards,
Brian

Hi!

Did you find any solution? I have exactly the same problem. If browser is already running, it is brought to foreground but new url is not opened.
I'm using the very same code from the wiki example.

Any help, anyone?

Best regards,
Teemu V.

Hello -

I've copied the code I'm using below. It does work and also opens the new URL if the browser is already running. Note you'll need to add the SwEvent capability to your application build.

const TInt KWmlBrowserUid = 0x10008D39;
TUid id( TUid::Uid( KWmlBrowserUid ) );
RWsSession wsSession;

User::LeaveIfError(wsSession.Connect());
CleanupClosePushL(wsSession);

TApaTaskList taskList( wsSession );
TApaTask task = taskList.FindApp( id );

if ( task.Exists() )
{
task.BringToForeground();
HBufC8* param = HBufC8::NewLC( aUrl.Length() + 2);
param->Des().Append(_L("4 "));
param->Des().Append(aUrl);
task.SendMessage( TUid::Uid( 0 ), *param ); // Uid is not used
CleanupStack::PopAndDestroy(param);
}
else
{
HBufC16* param = HBufC16::NewLC( aUrl.Length() + 2);
param->Des().Append(_L("4 "));
param->Des().Append(aUrl);
RApaLsSession appArcSession;
// connect to AppArc server
User::LeaveIfError(appArcSession.Connect());
TThreadId id;
appArcSession.StartDocument( *param, TUid::Uid( KWmlBrowserUid), id );
appArcSession.Close();
CleanupStack::PopAndDestroy(param);
}

CleanupStack::PopAndDestroy();
