Hi,
FYI I was unable to launch Tizen Lockscreen App with ID 'org.tizen.lockscreen' directly via LaunchApplication and I do not find api to perform this action in Tizen::Shell::LockManager class, It allows unlock only.

AFAIK there are no API to lock the screen! And also to unlock you need platform privilege.

Kimi,

Hi All,
Sorry for my previous response. I just forgot to add 'http://tizen.org/privilege/application.launch' privilege in manifest.
After this I was able to start lockscreen app directly from my native App.
    AppId callerAppId = L"org.tizen.lockscreen";
    AppManager* pAppManager = AppManager::GetInstance();
    result res=pAppManager->LaunchApplication(callerAppId, AppManager::LAUNCH_OPTION_DEFAULT);
Alexey.

For back button, you can disable it by not adding the listener to it in your app

Dont use SetFormBackEventListener(this);

Hi,
just fyu,
home and lock-screen appIDs could be different on different devices (M0/M1/Commercial) so to obtain them in Native apps you could use:

Tizen::Base::String _homeAppId, _lockAppId;
SettingInfo::GetValue(L"http://tizen.org/setting/application.home", _homeAppId);
SettingInfo::GetValue(L"http://tizen.org/setting/application.lock", _lockAppId);

Hi
Simple way:I could suggest to use Tizen::Ui::Controls::Popup to lock your App with Edit/Text Box to input password for unlock.

There is one known way (for Home button): You should set for frame highest priority on initialization
Tizen::Ui::Window::SetZOrderGroup(WINDOW_Z_ORDER_GROUP_HIGH)
and handle home button manually inside OnKeyPressed of IPropagatedKeyEventListener.
But you need platform privilege level for SetZOrderGroup api.
