If we want to identify all the installed packages on an android device / mobile, we need to use below command,
$ adb shell
$ cmd package list packages
In the older versions of android, you can also try using
$ pm list packages
For “cmd package” command following more options are available,
list packages [-f] [-d] [-e] [-s] [-3] [-i] [-l] [-u] [-U] [--uid UID] [--user USER_ID] [FILTER]
Prints all packages; optionally only those whose name contains
the text in FILTER.
Options:
-f: see their associated file
-d: filter to only show disabled packages
-e: filter to only show enabled packages
-s: filter to only show system packages
-3: filter to only show third party packages
-i: see the installer for the packages
-l: ignored (used for compatibility with older releases)
-U: also show the package UID
-u: also include uninstalled packages
--uid UID: filter to only show packages with the given UID
--user USER_ID: only list packages belonging to the given user
