Sorry, my mistake. Of course for settings it is better to use the appropriate intent action.
But for many applications, the launcher intent is simply MAIN (in category LAUNCHER), so there is no way to differentiate between different applications, except by their component - right? (or is it easily possible to specify the intent MAIN restricted to a specific package? rather than specifying the full component?)
