我们通常使用下面的代码启动浏览器并打开指定网页:

void OpenUrlL(const TDesC& aUrl)
{
if(aUrl.Length() <= 0)
return;
 
HBufC* param = HBufC::NewLC( aUrl.Length() + 8 );
param->Des().Format( _L( "4 %S" ),&aUrl );
 
// Wap Browser's constants UId
const TInt KWmlBrowserUid = 0x10008D39;
TUid id( TUid::Uid( KWmlBrowserUid ) );
 
TApaTaskList taskList( CEikonEnv::Static()->WsSession() );
TApaTask task = taskList.FindApp( id );
if ( task.Exists() )
{
HBufC8* param8 = HBufC8::NewLC( param->Length() * 4 );
param8->Des().Append( *param );
task.SendMessage( TUid::Uid( 0 ), *param8 ); // Uid is not used
CleanupStack::PopAndDestroy(); // param8
}
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
return;
}

然而在S60 3rd的设备上存在两个浏览器"网络"和"服务","网络"UID是0x1020724D,"服务"的UID是0x10008D39,上面的代码会启动"服务",但是确不能打开指定的网页,如果把UID换成"网络"的UID是可以正常打开的,可是在S60 3rd FP1的设备上只剩下一个浏览器,UID为0x10008D39,这就造成了代码通用性的问题,为了避免生成两个版本的程序,我们可以首先查找0x1020724D这个UID对应的程序是否在系统中存在,如果存在说明手机的基于S60 3rd的,如果不存那么就是基于S60 3rd FP1的,这时我们使用0x10008D39就可以了:

void OpenUrlL(const TDesC& aUrl)
{
if(aUrl.Length() <= 0)
return;
 
const TInt KBrowserUid1 = 0x1020724D;
const TInt KBrowserUid2 = 0x10008D39;
 
RApaLsSession appArcSession;
User::LeaveIfError(appArcSession.Connect()); // connect to AppArc server
 
HBufC* param = HBufC::NewLC( aUrl.Length() + 8 );
param->Des().Format( _L( "4 %S" ),&aUrl );
 
// Wap Browser's constants UId
TUid browserId( TUid::Uid( KBrowserUid1 ) );
 
TApaAppInfo appInfo;
if( appArcSession.GetAppInfo( appInfo, browserId ) != KErrNone )
{
browserId = TUid::Uid( KBrowserUid2 );
}
 
TApaTaskList taskList( CEikonEnv::Static()->WsSession() );
TApaTask task = taskList.FindApp( browserId );
if ( task.Exists() )
{
HBufC8* param8 = HBufC8::NewLC( param->Length() * 4 );
param8->Des().Append( *param );
task.SendMessage( TUid::Uid( 0 ), *param8 ); // Uid is not used
CleanupStack::PopAndDestroy(); // param8
}
else
{
TThreadId id;
appArcSession.StartDocument( *param, browserId, id );
}
 
appArcSession.Close();
CleanupStack::PopAndDestroy(); // param
return;
}

上面的代码在E50和N95上验证通过.
