_LIT(KFlashHiShowMyUril,"http://wap.shanxiu.net/wapLoginAction.do?method=clientLogin&loginUser=13606493540");//我的闪秀
// Load a string from the resource file and display it
TUid id(TUid::Uid(0x10008D39));
TApaTaskList taskList(CEikonEnv::Static()->WsSession());
TApaTask task = taskList.FindApp(id);
RApaLsSession appArcSession;
TThreadId thread_id = 0;

TBuf<256> urllink;
urllink.Copy(KFlashHiShowMyUril);



if (task.Exists())
{

// task.SendMessage(TUid::Uid(0), urllink); // Uid is not used
CleanupStack::PopAndDestroy();
}
else
{
User::LeaveIfError(appArcSession.Connect()); // connect to AppArc server
appArcSession.StartDocument(urllink, TUid::Uid(0x10008D39), thread_id);
appArcSession.Close();
}

但是在测试程序上 调用成功在工程失败
