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
