title: How to launch system apps programmatically or how to filter out launchable system apps?
body: <p>I want to make  a list of installed and system applications. system applications means the pre-installed applications (applications which are installed at the time of manufacture).
  For this i categorized all the apps using <code>(ApplicationInfo.flags &amp; ApplicationInfo.FLAG_SYSTEM) != 0</code> - which are system apps and others are installed apps.
  Now my problem is i want to launch these  apps on click of list items.But i could not launch system apps like Contacts,Dialer etc...</p>
