Tizen Developers

You can create a 'Service' application which will always be running in the background. Please refer -> https://developer.tizen.org/help/index.jsp?topic=%2Forg.tizen.native.appprogramming%2Fhtml%2Fguide%2Fapp%2Fservice_app_fundamentals.htm

You can launch application at a later time by using RegisterAppLaunch() method provided in Tizen::App::AppManager Class. Writing the condition in the OnTerminating() callback method should work for your purpose. You can refer this article for sample code -> https://developer.tizen.org/documentation/articles/native-appmanagement 

Hi
Try this api also:
Tizen::App::App::OnAppWillTerminate
The OnAppWillTerminate() method returns false to prevent the application from getting terminated...
Alexey.

thank you. I did it.

And now i have problem with drap & drop event. U can give me some sample code about it?

I following:https://developer.tizen.org/documentation/articles/working-drag-and-drop

But it not show drap animation.

You can check the sample application 'Dynamic Box Viewer' which contains such a drag-drop feature.
