application getting launched even if it is open android -

As soon as the user clicks on an app icon from the menu, the app is launching. This is also happening if the application has previously been opened.

I would like to maintain the state like if the application is opened then the app should display the default opened page and it should not be launched again.

Please tell me your valuable suggestions.

Thank you in advance :)

I resolved this issue. Before I was using Android: Launchmoda as an example. When I corrected my work with it :)
