What is the best way to detect when an Android "Application" has been launched from the Home screen/History screen?
Basically, what I'm trying to achieve is force the user to login to certain screens each time they come back to the app (i.e. they have full access to all activities once logged in, but essentially I want them to re-authenticate when they come back to the app via launching on the home screen).
I know similar questions have been asked before (i.e. how to log launches of an app) - but none that I have seen has yet been able to solve my problem. All ideas welcome...

Activities will very often need to support the CATEGORY_DEFAULT so that they can be found by Context. startActivity(). So, CATEGORY_DEFAULT can appear number of times. Android does not grab whichever one appears first in the manifest but it starts with activity having CATEGORY_LAUNCHER.
Navigate to APPS and select the app u want by long press. And then hit the Info button on top right corner. Thats it , it will show u the modified or installed time.

What about
if((getIntent().getFlags() & Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY )!=0) {
Log.d(TAG, "Called from history");
}
? This uses a simple Intent flag.
