Right now, what is happening is when I press home-key, last active activity is displayed. But what I want is to start the application as new every time the user presses home key and start the app from launcher. Please help

    Why? What does the user gain by your proposed behavior? – CommonsWare Jan 03 '13 at 14:30
  • Security .. Consider this case - the user presses the home key and forgets to log out of the app and later, when the app is relaunched, instead of asking for user-credentials, app's data is shown directly. – Rookie Jan 03 '13 at 14:38

    Implement a configurable timeout mechanism for user credentials, rather than blindly wiping them out simply because something else took over the foreground. – CommonsWare Jan 03 '13 at 14:55

I think you can override onPause() event when you pressing home button and in there you can implement finishing your activity. with setting intent flag as FLAG_ACTIVITY_CLEAR_TOP on starting your Activity your back stack would be clear so with finishing the last activity there is no activity on the task and stack

While creating intent you can set the flag. for example 

   Intent intent = new Intent();
   intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
