In linux I like to launch the applications from the terminal. Most of the time it is the fast way to launch apps especially on repeated use. In android there are good launcher like Fast app search tool will do the job well. But I still interested in launching apps fom the terminal. For that I installed JS Terminal but I can't see any app names. Even pressing Ctrl + T does't show any app name.
am start -a android.intent.action.MAIN -n <package_name>/<full_class_name>
