How to launch an application with its UID
Article Metadata
We can launch any application installed on a device with it's UID rather using the name of the application .
- By this way we can prevent the name clashes.
- No need for searching for the full path of the application.
In mmp file:
LIBRARY apgrfx.lib // for RApaLsSession
LIBRARY apparc.lib // for CApaCommandLine, TApaAppInfo
Source code
// System Includes
#include <apgcli.h> // for RApaLsSession
#include <apacmdln.h> // for CApaCommandLine
// ...
// ----------------------------------------------------------------------------
// CMyUtility::LaunchAppL(const TUid aAppUid)
// Find the application with it's UID and if exists then launch the
// application to the foreground.
// ----------------------------------------------------------------------------
//
void CMyUtility::LaunchAppL(const TUid aAppUid) const
{
RApaLsSession apaLsSession;
User::LeaveIfError(apaLsSession.Connect());
CleanupClosePushL(apaLsSession);
TApaAppInfo appInfo;
TInt retVal = apaLsSession.GetAppInfo(appInfo, aAppUid);
if(retVal == KErrNone)
{
CApaCommandLine* cmdLine = CApaCommandLine::NewLC();
cmdLine->SetExecutableNameL(appInfo.iFullName);
cmdLine->SetCommandL(EApaCommandRun);
User::LeaveIfError( apaLsSession.StartApp(*cmdLine) );
CleanupStack::PopAndDestroy(cmdLine);
}
else
{
// The application not found!
}
CleanupStack::PopAndDestroy(&apaLsSession);
}
